SECTION I – GENERAL DESCRIPTION
1-1. GENERAL. Yale “Global King” electric hoists
are wire rope and drum type hoists that are
manufactured with an integral trolley. These hoists
are all low headroom models with the drum and
upper block (or dead-end anchor depending on the
reeving type) on opposite sides of the beam
suspending the trolley. There are two basic frame
sizes each with two standard lifts: the “B” Frame
handles capacities up to 5 tonne; and the “C” Frame
handles capacities up to 10 tonne. The “B” Frame
has an integral trolley with two different flange width
ranges available: 4-5/8” through 14” or 14-1/8”
through 20” wide with a maximum flange thickness
of 1-3/4”. The “C” Frame integral trolley has a flange
range of 4 5/8” through 20” with a maximum flange
thickness of 2”. The hoist motor is 2-speed with a 6:1
ratio between high and low speeds as standard. The
Motor Driven trolley has two available speeds with 1speed, 2-speed, or Variable Frequency control.
Throughout this manual you will see references to
the “B” or “C” frame hoists. If you are unsure about
which frame size you have, see Section IV,
Paragraph 4-2 for a simple gearcase measurement
to easily determine the size of your hoist.
1-2. BASIC CONSTRUCTION. Yale “Global King”
hoists consist of a rugged steel frame which houses
a lifting drum and serves as the suspension for
carrying the entire hoist load. An aluminum
gearcase, attached to one end of the drum frame,
houses a triple-reduction gear train. The first two
reductions are helical with the third being spur.
Attached to the gearcase is a 2-speed hoisting
motor with a 6:1 ratio between the high and low
speeds. A 200% torque DC motor brake is attached
to the motor. A single NEMA 4/12 control enclosure
contains both the hoist and trolley electrical system
controls. Hoisting cable and a covered lower block
assembly are used for lifting loads. A rotary geared
limit switch is used to limit travel both up and down.
A secondary block operated limit switch is used to
limit the travel of the lower block when raising. A
push button control station (purchased separately)
for operating the hoist is suspended on a wire strain
cable attached to the hoist.
SECTION II – INSTALLATION
WARNING
Only qualified personnel properly
supervised shall mount the hoist and
trolley on the monorail and perform final
pre-operation inspection.
2-1. GENERAL. Yale “Global King” electric hoists
are lubricated and tested before being shipped from
the factory. To place a hoist in service, adjust
appropriately for the beam flange width (Paragraph
2-2), connect to electrical service (Paragraph 2-3)
and perform pre-operation tests and checks
(Paragraph 2-4).
WARNING
Working in or near exposed energized
electrical equipment presents the danger
of electric shock.
TO AVOID INJURY:
DISCONNECT POWER AND IMPLEMENT
LOCKOUT/TAGOUT PROCEDURE BEFORE
REMOVING COVER OR SERVICING THIS
EQUIPMENT.
2-2. SUSPENDING HOIST.
FIGURE 2-1. Trolley Wheel Spacing.
a) OPEN-END BEAM: If the trolley can be
installed directly from the end of the
supporting beam, adjust the spacing
between the trolley wheel flanges to be
3/16”-1/4” greater than the exact width of the
beam flange (See Figure 2-1). Before
adjusting the width of the trolley frame be
sure to loosen the clamp collar nearest the
traverse drive on the hex traverse drive
shaft. Also, the electrical conduit/cable must
not be constrained when attempting to
adjust the trolley sides in or out.
NOTICE
Loosen all electrical cable or conduit
attached to the frame and alignment bars
before adjusting trolley width. Ensure
that the electrical cable is not stretched,
pinched, twisted or otherwise damaged
when adjusting trolley width.
4
The trolley width shall be adjusted by
loosening the jam nuts on the traverse drive
side of the threaded rods at each end of the
hoist. If necessary, lubricate the frame
alignment bars with penetrating oil before
attempting to adjust trolley width. The trolley
side may then be pushed or driven into
position by turning the adjusting nuts on the
treaded rods. Adjust nuts on each side of
the hoist simultaneously to avoid binding.
After adjusting the trolley to the proper
width, tighten all adjusting nuts and the
clamp collar, and re-secure the electrical
conduit/cable. Verify that the geared wheels
mesh properly with the traverse drive
pinions. Using proper equipment, carefully
lift the trolley and hoist and install on the end
of the beam. Lubricate the wheel gear and
pinion (WG, Section IV, Paragraph 4-3).
b) CLOSED-END BEAM
are to be mounted along the span of a beam
not having open ends, the trolley must be
adjusted in the same manner as described
above to a width that allows clearance
between the axles and the beam flange.
Using proper lifting equipment, the trolley
and hoist must then be lifted to the beam
where it is to be installed. Once in position,
adjust the spacing between the trolley wheel
flanges to be 3/16”-1/4”” greater than the
exact width of the beam flange (See Figure
2-1). After tightening all adjusting bolts, the
clamp collar, and all electrical conduit/cable
clamps, carefully set the trolley on the beam.
Lubricate the wheel gear and pinion (WG,
Section IV, Paragraph 4-3).
2-3. CONNECTING HOIST TO ELECTRICAL
SERVICE. Electrical service to the hoist may be
power cable or a guarded system having sliding
shoe or wheel type collectors.
: For trolleys which
WARNING
Be certain that electrical power supply is
OFF and locked in the open position
before attempting any electrical
connections to the hoist. This equipment
must be effectively grounded according
to the National Electric Code ANSI/NFPA
70, or other applicable codes. If the
grounding method used is through the
trolley wheels, then each section of track
must be grounded by metal-to-metal
connection to the building ground.
Certain environments may prevent
proper grounding by this means. In this
case a separate grounding conductor
should be provided.
a) Follow ANSI/NFPA 70, state, and local
electrical codes including the grounding
provisions thereof when providing electrical
service to the hoist.
b) Make electrical connections using the
appropriate wiring diagrams furnished with
the hoist. All electrical connections
connections to collectors or power cord shall
be made only by qualified journeyman
electricians.
, including
CAUTION
Power supply to hoist and trolley must
be the same voltage, frequency, and
phase that are specified on the hoist and
trolley nameplate.
2-4. PRE-OPERATION CHECKS.
a) Check Oil Level.
has been filled with oil to the proper level.
However this should be re-checked before
operating the hoist.
Check oil level by removing the plug
indicated in Figure 2-1. When properly filled,
oil should be level with the bottom of the
tapped hole. Fill to this level with oil as
specified in Paragraph 4-2.e.
b) Check Push Button Operation and Phasing.
To properly check the phase of the hoist,
follow these steps:
(1) With “POWER OFF” operate all the push
buttons and determine that they do not
bind or stick in any position.
(Figure 2-1) The gearcase
WARNING
If any push button binds or sticks in any
position – DO NOT TURN POWER ON –
determine the cause and correct the
malfunction before operating.
(2) Connect hoist to power source.
WARNING
On three phase hoists it is possible to
have “Reverse Phasing” causing the
block to lower when the “UP” button is
depressed. When this condition exists
the automatic limit switch is inoperative
and hoist operation will be dangerous.
5
(3) Operate “UP” button briefly to determine
direction of hook travel.
(4) If hook raises when “UP” button is
depressed, phasing is correct.
(5) If hook lowers when “UP” button is
depressed, hoist is “Reverse Phased.”
TURN AND LOCK POWER OFF and
check the pushbutton wiring. If the
pushbutton was wired properly, correct the
problem by interchanging any two leads at
power source
internal wiring of hoist.
c) Check Limit Switch Operation.
(1) A block operated upper limit stop is
furnished as standard equipment on all
Yale “Global King” hoists. This limit stop is
factory set to stop the lower block at the
safest high position, guarding against over
travel and possible damage to hoist. No
adjustment can be made. However, the
hoist should be tested by jogging the lower
block against the limit weight to be sure
the limit switch is functioning properly.
When lower block lifts the limit weight, the
hoist will automatically stop. If lower block
coasts through the limit switch when lifting
a reversing switch will automatically close
and reverse direction of motion to
lowering.
connection. Do not change
WARNING
Damage to the hoist, a dropped load, and
injury may result if limit switches fail due
to improper use.
TO AVOID INJURY:
UNDER NORMAL OPERATING CONDITIONS,
STOP HOIST TRAVEL BEFORE ENGAGING
LIMIT SWITCHES. LIMIT SWITCHES ARE
SAFETY DEVICES AND SHOULD NOT BE
USED AS NORMAL OPERATING CONTROL.
WARNING
Some hoists may be shipped with the
electrical controls loose (disconnected)
and will not have the upper and lower
limit switches connected. DO NOT
OPERATE HOIST UNTIL LIMIT SWITCHES ARE PROPERLY CONNECTED AND
ADJUSTED. Failure to do so may allow
hoist to be operated beyond proper travel
limits, which can cause load to drop,
resulting in damage to equipment or
injury.
6
(2) A geared rotary type upper and lower limit
switch is also provided as standard. This
switch is adjustable and although roughly
preset by the factory, it should be adjusted
at time of installation to the desired high
and low limits of lower block travel. Refer
to SECTION VII, Paragraph 7-3.
d) Check Lower Block and Hoisting Cable.
Depress “DOWN” push button and run lower
block to its lowest position. No less than two
wraps shall remain on the drum with the
loaded hook in its lowest position. Also
check to see that the lower block and rope
do not twist excessively. If it does twist to
the extent that two ropes rub against each
other, disengage the swaged rope end from
the frame anchor and twist the rope four or
five turns in a direction opposite to that
which the block turns. Reconnect rope to the
frame anchor, holding firmly to eliminate
rope twisting back to its original position.
Operate hoist up and down a few times. If
lower block still rotates excessively repeat
process until twisting is corrected.
e) Lubricate Hoisting Cable.
life, it is recommended that the cable be
lubricated at time of installation by applying
a heavy coating of lubricant CL (Paragraph
4-7) as outlined in SECTION IV, Paragraph
4-3.
f) When first using the hoist and trolley,
operate with lighter loads through full travel
before applying maximum load.
For longer cable
SECTION III – OPERATION
3-1. GENERAL. Operation of Yale “Global King”
hoists is controlled by a convenient pendant push
button station. With it, the hoist can be controlled to
give fast lifting and lowering; or controlled to lift or
lower the load in small increments, providing
accurate spotting. The push button station has a
built-in interlock to prevent depressing opposing
buttons simultaneously.
When first using the hoist, break in by operating
under lighter loads to full travel before applying
maximum load.
3-2. PUSH BUTTON OPERATION.
a) Depress push button marked “UP” to raise
load.
b) Depress push button marked “DOWN” to
lower load.
c) Depress push button marked “RIGHT” to
traverse one direction.
d) Depress push button marked “LEFT” to
traverse in the opposite direction.
CAUTION
Excessive “jogging” will cause
premature burning of contact tips, motor
overheating, and premature brake wear.
e) On two-speed hoist or trolley motions, partial
depression of a button operates hoist or
trolley at slow speed; depressing button
completely operates hoist or trolley at full
speed.
3-3. OPERATING PRECAUTIONS. Safe operation
of an overhead hoist is the operator’s responsibility.
Listed below are some basic rules that can make an
operator aware of dangerous practices to avoid and
precautions to take for his own safety and the safety

4-1. GENERAL. The lubrication services outlined in
Paragraphs 4-3 thru 4-6 should be performed before
initial operation of the hoist. The lubrication services
outlined in Paragraphs 4-2 thru 4-6 should be
performed at regular intervals at least every six (6)
months, coinciding with spring and fall seasons is
recommended. The reason for this is that on hoists
installed outside or in unheated areas a “cold test” oil
is required in such (below freezing) climates making
seasonal changes necessary.
4-2. CHANGING GEARCASE OIL.
doubt of the supporting structure’s strength,
consult a structural engineer.
WARNING
DO NOT operate hoist with the hoisting
rope out of the drum grooves. Such
operation may result in damage to the
rope and/or the rope breaking. This may
result in dropping the load that can
cause damage to equipment and injury to
operator or other personnel. Hoist rope
will remain in the drum grooves during
operation under normal operating conditions, however, slack or kinked rope,
excessive side pulls, swinging or jerking
of load, or similar abuse, may cause the
rope to leave the grooves.
vv) DO NOT use hoist in location that will not
allow operator movement to be free of the
load.
ww) DO, when starting to lift, move the load a
few inches at which time the hoist should be
checked for proper load holding action. The
operation shall be continued only after the
operator is assured that the hoist is
operating properly and that the load is
supported in the center of the
base/bowl/saddle of the hook.
xx) DO Observe recommended inspection and
maintenance procedures.
yy) DO Use common sense and best judgment
whenever operating a hoist.
SECTION IV – LUBRICATION
a) Add 5% solution of Mobilsol A (or
equivalent) to the oil and run for a short
time. This will clean components and hold
particles in suspension for draining.
e) Refill through filler hole to proper level
(bottom of oil level plug hole) using GCOH
(Paragraph 4-7). The amount of oil required
depends on overall size of gearcase; two
sizes are used for “Global King” hoists. To
determine size and amount of oil to add,
measure width of hoist gearcase (see Figure
4-2). The “B” Frame measures 11-3/4” and
requires approximately 6 quarts of oil. The
“C” Frame’s width is 14-1/2” and requires
approximately12 quarts of oil.
FIGURE 4-1. View of Hoist Showing Location of
Name Plates and Oil Plugs.
b) Remove oil drain plug from bottom of
gearcase and drain oil out. Dispose of oil in
accordance with local environmental codes.
WARNING
Avoid skin contact with Mobilsol A. In
case of skin contact: dry wipe the skin,
cleanse the area with a waterless hand
cleaner and follow by washing
thoroughly with soap and water.
c) Reinstall drain plug.
d) Remove oil level plug from front of gearcase
cover.
FIGURE 4-2. Gearcase Width Illustration.
4-3. LUBRICATION OF HOISTING CABLE. Hoists
are shipped from the factory without an exterior
coating of grease on hoisting cable. It is
recommended, where conditions permit, that the
cable be thoroughly coated at installation and kept
well lubricated with CL (Paragraph 4-7).
4-4. LUBRICATION OF LIMIT SWITCH. Provide a
light film of grease MPG (Paragraph 4-7) on bevel
gear of rotary geared limit switch.
4-5. LUBRICATION OF GEARED TROLLEY
WHEELS AND PINIONS. At installation and
periodically apply grease WG (Paragraph 4-7) to the
traverse drive pinions and the gears of the trolley
wheels.
4-6. LUBRICATION OF ROPE GUIDE
a) Maintenance
following actions are required:
(1) Periodically re-grease with MPG
(Paragraph 4-7) using the grease fitting
provided (Figure 5-3, Item 6).
(2) Every 6 months the rope guide should be
removed per Section V, Paragraph 5-5,
cleaned and inspected. When the rope
guide is reassembled, the rope guide
should be thoroughly greased with MPG
(Paragraph 4-7) and the hoist run up and
down to lubricate both the drum and the
wire rope.

SECTION V – INSPECTION AND
PREVENTATIVE MAINTENANCE
5-1. GENERAL. All Yale “Global King” hoists are
inspected and tested at the factory. Regular inservice inspection and preventative maintenance
programs not only help reduce overall maintenance
costs but may also prevent service shutdowns by
forewarning of problems that could cause these
shutdowns. Regular inspections, periodic minor
adjustments, regular cleaning and lubrication and
replacement of worn parts can help preserve good
performance and operation of your hoist.
Many factors influence the inspection and
preventative maintenance program required for your
hoist. Frequency and severity of service and material
handled, local environmental conditions and various
applicable codes are some of the factors that the
user must consider to adjust inspection and
maintenance program outlined in this section to
meet his specific conditions.
The inspection and maintenance services outlined in
this section are considered minimum.
Recommended in the schedule are minimum
inspection and maintenance intervals based on
average daily use in a normal environment. Average
daily use is based on 1000 total operational hours
per year maximum and intermittent operation of the
hoist eight hours per day, five days per week with a
maximum 50 percent “on” time and the average
loading not exceeding 65 percent of rated load. For
more details regarding hoist duty cycles, please
reference ANSI/ASTM HST-4.
Environmental conditions in which the hoist operates
are also important considerations for the user when
adjusting hoist inspection and maintenance
programs to local conditions. Frequency of
inspection and maintenance must be increased if
hoist is subjected to severe atmospheric
AMBIENT TEMPERATURE
(10° to 38°C) (38° to 121°C)

environmental conditions, such as corrosive vapors,
extreme heat or cold, cement or dust and other
airborne contaminants. The user should carefully
consider all environmental conditions and adjust
frequency and degree of maintenance for his local
conditions. Consult the factory’s Field Service
Department for advice regarding unusual environmental conditions.
Various codes also regulate inspection and
maintenance programs. Attention must be given to
applicable federal standards, OSHA regulations,
national standards, state and local codes which may
include mandatory rules relating to hoist inspection
and maintenance. The user should become familiar
with all applicable codes for his area and be guided
accordingly.
Listed on the Recommended Inspection and
Maintenance Schedule are inspection frequencies
and requirements. Perform these inspections
regularly as scheduled and additional inspections as
may be required for activity, service, and environment of your hoist. The hoist operator must be
responsible for determining the operating conditions
and severity of service.
Inspection Schedule and Maintenance Report Form.
Shown on page 13 of this manual is a recommended
Inspection Schedule and Maintenance Report form
that lists various components of the hoist. The form
also includes trolley components, runway components, and miscellaneous items. This form is
suggested as a guide for written inspection reports.
Inspections are recommended each month and
should be performed thoroughly enough to inform
the hoist user of deficiencies for any item listed. This
form does not supersede the Inspection and
Maintenance Schedule listed on page 12 of this
manual but may be used to record scheduled
inspection and maintenance services required.

The user should revise the inspection interval, add
additional units or provide a similar form to suit
particular conditions that may exist. However,
written, dated and signed inspection reports should
be maintained particularly on critical items such as
hoist hooks, hoisting rope, sheaves, drums and
brakes. Periodic review of old inspection reports can
point out service life of hoist components,
forecasting need for adjustment, repair or
replacement of these components.
As a matter of expedience, appointed maintenance
personnel inspecting hoist can also take care of
minor adjustments, repairs and cleaning, where
required. Note column on Inspection Schedule and
Maintenance Report form headed Corrective Action
and Notes. When corrective action is made during
inspection, note condition of part or unit as inspected
in appropriate Condition
(`). Note “during inspection” corrective action taken
and date in space provided. In this manner, items
requiring further attention will be checked (`)
without showing corrective action. This will advise
the designated person responsible for hoist
operation and safety, who reviews the reports that
deficiencies exist. The designated person will check
all deficiencies as listed and re-examine or otherwise
determine whether they constitute
column with a check mark
asafety hazard.
WARNING
Deficiencies may be hazardous to
personnel and equipment. Do not operate
a hoist having deficiencies unless a
designated qualified person has
determined that these deficiencies DO
NOT constitute a safety hazard.
Written, dated and signed inspection reports for
many items are mandatory under OSHA regulations,
and many state safety codes. It is strongly
recommended that the Inspection Schedule and
Maintenance Report, shown herein, be completed by
a qualified person designated with the responsibility
for hoist operation and safety or an inspector
appointed by this person.
Inspection records can point out the service life of
hoist components and help forecast the need for
adjustments, repairs, and ordering of replacement
parts. File and review these reports after each
inspection.

WARNING
Do not operate a hoist having unusual
vibrations, sounds, or with anything
wrong or apparently wrong. Danger may
be present that the hoist operator
cannot see. Determine and correct the
cause of unusual conditions and make
certain hoist can be operated safely.
5-2. INSPECTION OF LOWER BLOCK.
a) Check lubrication of all parts. Also lubricate
the shank of the hook that passes through
the crosshead. If the thrust bearing is
removed, apply MPG grease (Section IV,
Para. 4-7).
b) Check each sheave to insure rope groove
is smooth and free from burrs, or other
surface defects.
c) Check each sheave for freedom of rotation;
replace bearings if defective.
d) Make certain that the spring pin holding the
hook nut to the hook is securely in position.
e) If hook is equipped with a hook latch or
rotational lock, check to determine that they
are in good operating condition.
f) Check throat opening of the hook. (Refer to
Figure 5-2.) It is recommended that upon
receipt of the hoist, a measurement be
made and recorded of the hook throat
opening. OSHA regulations require that the
hook be replaced if the throat opening
exceeds 15 percent of the original opening,
or if the hook is twisted more than 10
degrees from the unbent plane. We
suggest that a gage block properly
identified to the hoist, similar to the one
shown in Figure 5-2, be made for each
hook for use in these measurements.
g) Hooks showing signs of cracks must be
replaced. Hooks should be inspected at
least once per year using dye penetrants,
magnetic particle, or other suitable nondestructive test methods.
h) Check wear of the hook, especially at the
saddle and replace if worn more than 10%
of original dimensions.
5-3. INSPECTION OF UPPER BLOCK.
a) Check upper block sheaves (when hoist is
so equipped) for wear, damage and
freedom of rotation.
If sheaves do not rotate freely, disassemble
block and inspect bearings. Replace worn
or damaged bearings, washers, pins, or
sheaves.
b) Make certain that all sheaves, bearing and
hanger pins are free of foreign material.
Bearings without grease fittings are
lubricated for the life of the bearing and
require no further lubrication.
c) Make certain that the rope retention bolts
are not bent, loose or otherwise distorted;
bolts must have close clearance to sheave
flange to keep rope in sheave grooves.
5-4. INSPECTION OF ELECTRICAL CONTROLS.
Arrangement of electrical control equipment varies
with the type of control, physical space and the
optional control features ordered with the hoist.
Note the location in the electrical enclosure of the
control circuit fuse, transformer, limit stop switches
and the hoist contactors. Trolley contactors and
optional hoist and trolley fuses are also located in
this enclosure.
Use wiring diagrams furnished with hoist to
determine electrical components on your hoist; then
determine component location and identity on your
hoist.

WARNING
Be certain that main power switch is
locked in open position (OFF) before
opening hinged control enclosure cover
mounted to the counterweight.
FIGURE 5-2 Gage Block.
a) Open hinged control panel enclosure cover
mounted to the counterweight and inspect
wiring and terminals. Terminals should be
securely crimped to wires and insulation
sound. Terminal screws should be tight.
b) Check condition of contactor assembly,
transformer, and upper limit switches.
WARNING
Check to be certain main power switch
is locked in open position (OFF) before
removing brake cover.

drum.
Once shoulder bolts are removed, the
halves will separate and, if not properly
supported, the halves could fall.
(3) Carefully unhook the rope tensioning spring
(Item 3), which is under tension.
The rope tensioning spring is under
considerable tension; use caution when
unhooking to avoid injury.
(4) Remove the split plastic shroud (Item 2)
from the drum. When reassembling the
rope guide be sure the plastic shroud (Item
2) fits snugly in the rope guide body
groove.

Figure 5-8. Hoist Gear Case Assembly.
a) General
reduction splash lubricated vertically split
cast aluminum case and cover. The first
two high-speed reductions are helical and
the third low speed output reduction is
. The hoist gear case is a triple
spur. The gear shafts are supported with
ball bearings housed in the back of the
case and in the cover. The input helical
pinion is cut directly into the motor shaft. An
oil seal housed in the gear case at the
motor input seals the motor shaft as it
passes into the gear case. Since the entire
motor shaft is submerged in oil, anytime the
motor is removed, the oil must be drained
from the gear case. All pinions are integral
with their shafts while the gears are keyed
and pressed onto their shafts. The output
shaft passes through an oil seal in the back
of the gear case and drives the drum by
means of a crowned spline. One end of the
rope drum is supported on this output shaft.
b) Inspection and Disassembly
Gearcase. (See Figure 5-8.)
(1) Lower hook block to the floor and relieve all
load from ropes.
(2) Make sure power to hoist is off and locked
out.
.
WARNING
Before disassembly, prevent rope drum
from free spinning by wedging drum in
place with a block of wood, and resting
lower block on work surface so all
weight is off rope drum. Rope may also
be removed from hoist drum.
(3) Drain the oil from the gear case per
Section IV, Paragraph 4-2.
(4) Provide adequate means to support the
gear case cover. Once the cover is
supported, remove the two (2) shoulder
bolts, seven (7) socket head cap screws,
and nine (9) lock washers holding the
cover to the gear case. Carefully draw
the cover directly away from the gear
case, as damage to this surface will
prevent the gasket from sealing properly.
As the cover is removed, ensure that all
gear and shaft assemblies remain in the
case.
WARNING
If output shaft assembly is pulled out of
the gear case with the cover, it will
disengage from the drum allowing the
drum to drop. Be certain all shaft
assemblies stay in the case.
(5) If it is necessary to remove the output
shaft assembly from the gear case, the
rope drum must first be removed from the
hoist. See Section V, Paragraph 5-7.
WARNING
The hoist must be removed from service
and repaired on the ground for any
maintenance that requires removal of
the output shaft assembly or drum.
Only once the output shaft is free of the
rope drum, can the output shaft assembly
be safely removed from the gear case.
Provide an adequate means to support
this shaft and gear assembly before
removing, as it weighs approximately 80
lbs. (“C” Frame Hoist).
(6) The pinion shaft and gear assemblies
may be removed as necessary.
(7) Inspect all gears, pinions, bearings, and
the output shaft spline for wear, pitting, or
mechanical damage. Replace as
necessary. See Section IX, Figure 9-2 for
replacement parts. It is recommended
that gears and pinions only be replaced
as sets. Thoroughly clean the output
shaft external spline teeth before
reassembly.
(8) Assembly is opposite of removal. Use a
new gasket. Do not attempt to assemble
the cover to the gear case without a
gasket, as the spacing between bearings
will be reduced. Severe damage to the
hoist will occur if no gasket or the wrong
gasket is used. Refill gear case with new
lubricant per Section IV, Paragraph 4-2
before use. Using SG (Paragraph 4-7),
grease the spline teeth on the output
shaft before reinstalling rope drum.
(9) Test hoist per Section V, Paragraph 5-13
to ensure proper lubrication.
Hoist Motor.
(1) Lower hook block to the floor and relieve all
load from ropes.
(2) Make sure power to hoist is off and locked
out.
(3) Drain the oil from the gear case per
Section IV, Paragraph 4-2.
19
(4) Disconnect the wiring and conduit from
the motor junction box.
(5) Provide a means to support the hoist
motor. The hoist motor weighs approximately 250 lbs. And must be held level
while removing and installing.
(6) Once the motor is properly supported,
remove the hardware fastening it to the
gear case. Carefully withdraw the motor
horizontally straight out from the gear
case. Do not tip or move the motor from
side to side.
(7) Replace the motor shaft seal using an
appropriate seal driver. It is
recommended that a new seal be
installed each time the motor is removed
from the case.
IMPORTANT!
(8) Before installing the motor, pack the gear
teeth with MPG grease (Paragraph 4-7)
and wrap the gear teeth with a number of
layers of Teflon tape to protect the seal
lip from being damaged by the gear
teeth. Coat the seal lip and the motor
shaft with MPG grease.
NOTICE
Failure to use a factory replacement seal
will cause premature seal failure due to
specific lip material requirements that
must be met.
(9) Install the motor to the gear case. The
motor shaft must be in line with the seal
bore and perpendicular to the mounting
surface before attempting to insert the
shaft through the seal. The motor shaft
must remain horizontal and not rock up
and down or side-to-side while installing
the motor or seal damage will occur. It
may be necessary to rotate the rope
drum slightly to align the gear teeth to
mesh with the teeth on the motor shaft.
Ensure that the motor seats properly into
the rabbet fit machined in the gear case.
Fasten the motor to the gear case.
(10) Reconnect the conduit and power
leads to the motor. See Section VIII
and refer to the specific wiring
diagrams shipped with your hoist.
(11) Refill gear case with lubricant per
Section IV, Paragraph 4-2.

(12) Test hoist to ensure proper operation
per Section V, Paragraph 5-13.
5-10. INSPECTION OF MOTOR BRAKE AND
ACTUATING MECHANISM.
a) General Operation
electro-magnetically released, spring set nonadjustable brake. Torque is generated by
compressing a friction disk between the
stationary motor end bell and the spring loaded
brake armature. The friction disk is fixed to the
motor shaft and rotates with the motor shaft.
When the magnet coil is energized, the
armature plate is pulled across the air gap. The
friction disk is carried by a splined hub that
permits axial movement when the brake is
released. This axial movement releases both
sides of the friction disk from their mating
stationary surfaces and allows the friction disk
to rotate freely when the brake is energized.
When power is removed from the magnetic
coil, the compression springs push the
armature against the friction disk and the other
side of the friction disk against the motor end
bell generating the torque necessary to stop
the hoist machinery and hold the load.
It will be necessary to compensate for the
friction disk wear when a greater amount of
hook movement (drift) is noticed when
stopping. There is no torque adjustment of the
brake. Friction disk wear can only be
compensated for by resetting air gap.
Figure 5-9. Motor Brake.
b) Friction Disk Inspection and Air Gap
Adjustment.
(1) Lower hook block to the floor and relieve
all load from ropes.
. The hoist brake is an
(2) Make sure power to the hoist is off and
locked out.
(3) Remove the four (4) bolts attaching the
fan shroud to the motor and remove the
fan shroud. See Figure 5-9.
(4) Carefully roll the large O-ring from the
groove over the air gap back toward the
magnet body. Do not excessively stretch
this O-ring.
(5) Measure the air gap using feeler gages.
If the air gap exceeds the maximum
value shown in Table 5-1, the air gap
must be reset.
(6) To measure the thickness of the friction
disk, it is necessary to remove the brake
body from the motor end bell. Remove
the three (3) brake mounting bolts and
draw the brake body away from the
friction disk. Carefully set the brake body
down on the motor shaft directly in front
of the fan. Draw the friction disk away
from the end bell and measure the
thickness over the friction surfaces. If the
friction disk thickness is less than the
minimum shown in Table 1, it must be
replaced. See Section IX, Figure 9-10. If
the friction disk thickness is within the
allowable, reassemble the brake body to
the motor end bell and torque the
mounting bolts to the value shown in
Table 5-1. Whenever the friction disk is
replaced, it is necessary to reset the air
gap.

(7) To reset the air gap, begin by releasing
the (3) mounting bolts 1/2 turn. Turn the
hollow spacer bolts into the magnet body
approximately 1/4 turn. Retighten all
three mounting screws. Measure the air
gap at a minimum of three places around
the circumference. Threading the hollow
spacer bolts into the magnet body will
decrease the air gap while backing these
spacer bolts out of the magnet body will
increase the air gap. Repeat this step as
necessary until the required air gap is

achieved. The air gap must be the same
all the way around the brake. Once the
air gap is correct, torque the mounting
bolts to the value shown in Table 5-1.
(8) Replace the large O-ring over the air gap
and reassemble the fan shroud to the
motor.
(9) Test hoist per Section V, Paragraph 5-13
to ensure proper brake operation.
c) Brake Disassembly
(1) Lower hook block to the floor and relieve
all load from ropes.
(2) Make sure power to the hoist is off and
locked out.
(3) Remove the four (4) bolts attaching the
fan shroud to the motor and remove the
fan shroud. See Figure 5-9.
(4) Remove the snap ring behind the plastic
fan. Carefully remove the fan from the
motor shaft. Remove the snap ring in
front of where the fan was mounted.
(5) Disconnect the two wires from the
terminal block on the magnetic body.
(6) Remove the three mounting bolts that
attach the brake body to the motor end
bell and remove the brake body from the
motor. Remove the friction disk from the
motor shaft.
(7) Clean and inspect all components and
working surfaces. Replace all damaged
or worn components as necessary.
Measure friction disk thickness and
replace if less than the minimum
thickness shown in Table 5-1.
d) Brake Re-assembly
(1) Install the friction disk on the splined hub.
The friction disk must slide on the splined
hub and seat against the end bell of the
motor.
(2) Install the brake body to the motor end
bell using the three (3) mounting bolts.
The air gap must be reset as described in
Section V, Paragraph 5-10.b. Torque the
mounting bolts to the values shown in
Table 5-1. Install the large O-ring in the
groove over the air gap. Ensure this Oring is not pinched in the air gap.

(5) Test hoist per Section V, Paragraph 5-13.
5-11. INSPECTION OF HOIST TRAVERSE
DRIVE.
Figure 5-10. Traverse Drive Arrangement.
a) General.
single flange wheels, two on each side of
the beam, carried directly by the hoist
frame. These wheels rotate on sealed ball
bearings supported by fixed pins. Pinions
drive two opposing wheels with gear teeth
cut into the flange. Both pinions are
mounted on a hexagonal drive shaft
supported by sealed ball bearings at each
hoist side. The pinions are held in place by
means of clamp collars. The drive shaft
passes through one hoist side and is driven
by a single reduction hollow shaft gear
reducer.
b) Ensure that the hoist is properly fitted to the
beam. The hoist must be centered on the
beam with clearance between the sides of
the bottom of the beam flange and the
inside faces of the wheel flanges. Proper
clearance must exist along the entire length
of beam that the hoist can traverse. An
amount of 3/32 to 1/8 inch clearance per
side is recommended for a total of 3/16 to
1/4 inch wider than the beam flange. If too
little or too much clearance is determined,
adjust trolley per Section II, Paragraph 2-2.
c) Inspect wheel treads, flanges, and gear
teeth for wear. Check for adequate
lubrication (WG, Section IV, Paragraph 4-7)
on the wheel gear and pinion mesh. Check
wheel bearings for any signs of wear,
including rough rotation and signs of
lubricant leakage. Replace all damaged or
22
The traverse drive consists of four
missing items. Wheels must always be
changed in opposing pairs and drive
wheels should be changed when the drive
pinions are replaced.
CAUTION
Ensure that the cross shaft is properly
positioned and locked into place by
means of the clamp collars. Failure to
do so may allow the drive shaft to
contact the rope on the rope drum (B
frame) or the hoist gearcase (C frame
hoist).
d) Examine the drive pinions, cross shaft, and
cross shaft bearings. Check pinions for
gear tooth wear and proper alignment with
wheel gear. A spacer washer between the
cross shaft bearings and the pinion aligns
the gear mesh. Clamp collars hold the
pinions and spacer washers tight against
the bearings. Verify that the clamp collars
are tight on the cross shaft. If it is
necessary to adjust or reset the clamp
collars, verify that the hex shaft surface is
free of mechanical damage and oil before
tightening the clamp collars. Drive pinions
must be replaced as sets and should be
replaced along with the drive wheels. The
cross shaft bearings are sealed for life and
should be replaced at any sign of
mechanical wear or lubricant leakage.
e) Inspect the traverse gearbox and motor.
Look for signs of rough operation,
mechanical damage or lubricant leaks.
Inspect the hollow bore and hexagonal
drive shaft for wear. Verify that the four
bolts that hold the gearbox to the trolley
frame and the four bolts that hold traverse
motor to the gearbox are all present and
tight. Replace and tighten as necessary.
The factory recommends complete
replacement of the traverse gearbox.
However, gearbox service may be
available from you local authorized Yale
repair center.

a) General.
a secondary upper limit switch actuated
when the lower block contacts the limit
switch weight. The rotary geared limit
switch (screw type limit switch) is the
primary upper limit switch and must be
temporarily disconnected to allow the block
operated limit switch to be tested.
The block operated limit switch is
b) Procedure. Remove load from the hook. To
disconnect the geared limit switch refer to
Figure 7-2. Remove the limit switch cover
then loosen the two (2) screws holding the
locking plate in place. Allow the locking
plate to slide down and disengage from the
adjustment discs. Do not rotate the
adjustment discs.
CAUTION
Damage to the hoist may occur if the
block operated limit switch fails during
testing.
Damage can be avoided by immediately
releasing the pushbutton once the lower
block has traveled through the limit
switch weight.
The block operated limit switch may now be
tested by slowly and carefully raising the
hook until the limit switch weight contacts
the lower block. If the hook does not stop
when the limit switch weight is lifted,
immediately release the pushbutton before
damage to your hoist occurs. If the block
operated switch functions properly, proceed
by testing in the same manner with rated
load on the hook.
Once it has been determined that the block
operated limit switch is functioning properly,
the geared limit switch must be
reconnected and tested.
Position the lower block three inches (3”)
below the point where the block operated
limit switch is activated. The geared limit
switch shall be reconnected by sliding the
locking plate back into position ensuring
slots on adjustment discs are fully engaged
and tightening locking plate screws to 4 inlbs. (See Figure 7-2). The geared limit
switch must then be tested.
Test the geared limit switch by raising the
lower block until it stops. Ensure that the
geared limit switch stopped the hoist before
the block operated limit switch was
activated. If this is not the case see Section
VII, Paragraph 7-3 for adjusting the geared
limit switch. Replace geared limit switch
cover when testing and adjusting is
complete.
WARNING
Check limit switch operation carefully,
without load, before placing hoist in
service. If misadjusted, SEVERE
DAMAGE AND/OR A DROPPED LOAD
COULD RESULT. Allow 3” for hook drift
in both directions. Never allow less than
two (2) complete wraps of rope on drum
with hook in lowest position.
5-13. TESTING HOIST.
a) General.
accordance with ANSI B30.16-2 and this
manual. Before placing hoist in service,
hoist should be tested to insure safe
operation when hoist has been
disassembled and reassembled. To test,
suspend hoist from an overhead supporting

“drifts” downward more than usual for your hoist
before coming to a stop, the motor brake may
require adjustment to compensate for brake disc
wear.
WARNING
Check to be certain main power switch
is locked in open position (OFF) before
removing brake cover.
Refer to Figure 5-9 and proceed as outlined in
Section V, Paragraph 5-10.
7-2. BLOCK OPERATED LIMIT SWITCH. The
block operated limit stop, furnished as standard
equipment, is non-adjustable and designed to stop
the lower block at the safest high point of travel to
eliminate any possibility of double-blocking. When
the safest high point is reached, the limit switch
automatically stops hook travel.
7-3. GEARED ROTARY LIMIT SWITCH
ADJUSTMENT. The geared rotary type limit switch
is standard equipment and is located on the drum
end opposite the gearcase end.
25
This limit switch has a rotary screw driven by a gear
reduction that is coupled to the end of the drum
shaft. Adjustment discs operate the contacts of
separate switches, one for the hoisting circuit and
one for the lowering circuit. The switch assembly
must be wired in accordance with the appropriate
wiring diagram, which is shipped with the hoist.
Instructions for adjusting limit switch are inside
cover and are repeated below (see Figure 7-2).
Be certain that electrical power supply
is OFF and locked in the open position
before removing limit switch cover.
a) Remove four screws and lift off switch
cover.
b) Loosen locking plate screws. Slide locking
plate away from adjustment disc.
c) Turn proper adjustment disc (right for up,
left for down) toward switch to reduce hook
travel or away from switch to increase hook
travel.
d) Slide locking plate back into position
ensuring slots on adjustment discs are fully
engaged, tighten locking plate screws to 4
in-lbs.
e) Replace cover.
f) Carefully check limit switch operation
without load before placing hoist in service.
If misadjusted, repeat steps above. Allow 3”
for hook drift in both directions. Never allow
less than two (2) complete wraps of rope
on drum with hook in lowest position.
WARNING
Check limit switch operation carefully,
without load, before placing hoist in
service. If misadjusted, SEVERE
DAMAGE AND/OR A DROPPED LOAD
COULD RESULT. Allow 3” for hook drift
in both directions. Never allow less than
two (2) complete wraps of rope on drum
with hook in lowest position.
Provide a light film of MPG grease (Paragraph 4-7)
on gear of both limit switches.
7-4. SHORTENING OF PUSHBUTTON CABLE.
WARNING
Be certain that electrical power supply
is OFF and locked in the open position
before attempting shortening of push
button cable.
a) Loosen screws at cable connectors and
clamps at top of cable.
b) Adjust steel support cable to proper length
and tighten screws.
c) Loosen upper cable grip and pull excess
cable into connection box at hoist.
d) Tighten cable grip and cut off excess cable.
e) Strip cable sheath and connect wires with
the same type of terminals previously
furnished (care must be taken to match
previous wire color coding with wire
markers in accordance with wiring diagram
furnished with hoist.)
SECTION VIII – WIRING DIAGRAMS
8-1. GENERAL. Comprehensive wiring diagrams for
Yale electric hoists have been omitted from this
book because of the many possible variations. This
is due to different currents and types of electrical
components used in their construction. Figures 8-1
and 8-2 are examples of typical two-speed hoist
and trolley wiring diagrams respectively. However,
please consult the exact wiring diagrams for your
hoist. A print of the correct wiring diagram for each
hoist is furnished as a separate insert and shipped
with the hoist. We suggest you carefully file the
wiring diagram with this book for future reference.

9-1. GENERAL. The parts lists and illustrations in
this section of the manual cover parts for models of
Yale “Global King” Electric hoists. A typical hoist is
shown as the basis for the exploded parts
illustrations; therefore, certain variations may occur
from the information given. For this reason, always
give the Hoist Serial Number, Catalog Number,
Motor Horsepower, Voltage, Phase, Frequency and
Capacity of Hoist when ordering parts.
Yale “Global King” Hoists are built in two basic
frame sizes, “B” Frame and “C” Frame. To
determine the size of your hoist, measure the width
of the gearcase (see Figure 4-2.) The “B” Frame’s
gearcase has a width of 11 3/4” and the “C” Frame
has a gearcase width of 14 1/2”.
Certain parts of your hoist will, in time, require
replacement under normal wear conditions. It is
suggested that these parts be purchased for your
hoist as spares for future use. These parts are
indicated by a (†) symbol at the side of the parts
reference numbers.
The numbers assigned to parts of our
various assemblies in our parts list are not
the part numbers used in manufacturing the
part. They are identification numbers, that
when given with the model number, permit
us to identify, select or manufacture, and
ship the correct part needed.
WHEN ORDERING PARTS OR INFORMATION
ON THIS EQUIPMENT, ALWAYS INCLUDE
MODEL AND SERIAL NUMBER ON ORDER.
WARNING
Using “Commercial” or other manufacturer’s parts to repair Global King
Hoists may cause load loss.
