GENERAL INFORMATION

SPECIFICATIONS

Yale LH2 Hand Hoists

The Yale LH2 Hand Hoist is a highly versatile
tool that can be used to lift loads. The hoist has
aluminum frame, handwheel, handwheel cover
and gear cover to provide dependable strength
at minimum weight. The internal gears are made
of high grade, heat treated steel. Shielded ball
bearings are used at each rotating point in the
mechanism. Latch type, heat treated, forged steel
upper and lower hooks are standard. The load chain
is strong and durable Hoistaloy

®

. A pawl and ratchet,
dry-operating, Weston-type friction brake supplies
very positive load control and will suspend the load
at any point. A Load Limiter is provided on every unit.
As a result, the application of an excessive overload
disengages the driving handwheel and prevents
hoisting. Note that the Load Limiter is not intended
for use as a scaling device. Removal of the excess
load automatically restores normal hoisting action
(see Figure 1 for specifications of available models).

Yale Low Headroom Trolley Hoists

The Yale Low Headroom Trolley Hoists (Figure 2, page 2)
are a combination of the Yale Hand Hoist built
integral with a rugged trolley to provide better head­room than that obtained with the standard hoist and
trolley. The basic hoist is similar to the Yale LH2 Hand
Hoist except the frame, aluminum on the 1/2 through
3 ton units and cast iron on the 4 through 6 ton units,
which is designed to provide low headroom and
attachment to the trolley. The trolley has a rugged
frame, cast iron on the 1/2 through 1 ton units, and
steel plates on the 1-1/2 through 6 ton units. Crowned
tread, flanged trackwheels are provided to minimize
rolling friction. Hardened, pressed steel ball bearing
wheels are used on the 1/2 and 1 ton units. Hardened,
cast iron wheels with Timken bearings are used on the
1-1/2 through 6 ton units. Trolleys are adjustable for
operation on various American standard beams and
the 1-1/2 through 6 ton units are available in a geared
type trolley.

UNPACKING INFORMATION

After removing the hoist from the carton, check to
be sure there has been no damage in shipment.
Before cutting the cord ties on multiple-reeved
units, be sure that all strands of chain are straight
with no twist (due to a capsized hook block). If
length of lift is to be modified, follow disassembly
and assembly instructions for correct procedure.

OPERATING INSTRUCTIONS

After mounting and before placing in service,
check the hoist for proper operation. On multi­reeved units, be sure that all strands of chain are
straight with no twist (due to a capsized hook
block).

The Yale Hand Hoist must always be rigged to lift
in a straight line from hook to hook (see Figure 4).
The hoist must always be free to swivel on the
upper hook. Under no condition should the hoist
be allowed to bear on any support when in use as
this would cause bending of the hook or frame
and damage the unit.

HOOKS

Type of hooks supplied on the Yale Hoists are shown
in Figure 3.

YALE REPAIR/REPLACEMENT POLICY

All Yale LH2 Hand Hoists and Low Headroom Trolley
Hoists are thoroughly inspected and performance
tested prior to shipment. If any properly maintained
Yale Hoist develops a performance problem due to a
material or workmanship defect, as verified by Yale or
an authorized service station, repair or replacement
of the unit will be made to the original purchaser
without charge. This repair/replacement policy applies
only to Yale Hoists installed, maintained and operated
as outlined in this manual, and specifically excludes
parts subject to normal wear, abuse, improper instal­lation, improper or inadequate maintenance, hostile
environmental effects, and unauthorized repairs/
modifications.

We reserve the right to change materials or design if
in our opinion, such changes will improve our product.
Abuse, repair by an unauthorized person, or use of
non-Yale replacement parts voids the guarantee and
could lead to dangerous operation. For full Terms of

TROLLEY INSTALLATION

Operating the trolley hoist on a beam that has no rail
stops may allow the trolley hoist to fall off the end of
the beam.

To Avoid Injury:

Install rail stops at each end of the beam on which
the trolley hoist is to operate.

The railstops must be positioned so as to not exert
impact force on the hoist portion of the unit or the
trolley wheels. They must contact the ends of the
trolley side frames.

Due to the variations in beam flange widths, it is sug­gested that the beam flange width be measured to
determine the exact distribution of spacer washers.
The distance between trackwheel flanges (dimension
“X”) should be 1/8 to 3/16 inch greater than the
beam flange width for straight runway beams, and
3/16 to 1/4 inch greater than the beam flange width
if runway system includes sharp curves. Also, the use
of other than Yale supplied washers may result in
trackwheel to beam flange variations and thus Figure
5 will not apply.

Assemble the trolley on the beam by sliding one side
out far enough to allow the wheels to clear the
beam flange. Draw side frames together and tighten
nuts securely (do not over tighten) and then install
the cotter pins.

If washer spacing recommendations are not followed,
trolley hoist may fall from beam.

To Avoid Injury:

Measure the actual beam flange on which the trolley
hoist is to operate and use figure 5 to determine the
arrangement of the spacer washers for that flange
width.

Immediately after installation, operate trolley with a
capacity load over the entire length of runway or
monorail system to be sure that all adjustments and
operations are satisfactory.

When applying a load, it should be directly under
the trolley. Avoid off center loading of any kind.
Side loading may spread trolley side frames.

On systems with curves, the edges of the rail at the
curved sections should be lightly lubricated with
grease.

An excessively worn beam flange may fail and
allow the trolley hoist to fall from the beam.

To Avoid Injury:

Periodically inspect the beam flange for wear.
Replace beam if flange is worn.

OPERATING AND SAFETY PROCEDURES

For safety precautions and a list of do’s and do not’s
for safe operation of hoists, refer to page ii.

The Yale LH2 Hand Hoist (see Figure 6) must always
be rigged to lift in a straight line from hook to
hook. The hoist must always be free to swivel on
the upper hook. Under no condition should the
hoist frame or hanger be allowed to bear on any
support when in use as this would cause bending of
the hook or frame and damage the unit.

When preparing to lift or move a load, be sure that
the attachments to both hooks are firmly seated in
the saddles of the hooks. Avoid off center loading
of any kind especially loading on the point of the
hook.

When lifting, raise the load only enough to clear
the floor or support, and check to be sure brake will
hold load and that attachments to the load are
firmly seated. Continue the lift only after you are
assured the load is free of all obstructions.

Do not load beyond the rated capacity of the hoist.
Overloading can cause immediate failure of some
load carrying part or result in damage causing fail­ure at less than rated capacity. When in doubt, use
the next larger capacity of Yale LH2 Hoist.

Do not wrap load chain around the load or bring
the load in contact with the hoist. Doing this will
result in the loss of the swivel effect of the hook
which could cause twisted chain and a jammed lift­wheel. The chain could be damaged at the hook.

Rail stops must be installed for all trolleys operating
on open end beams. These stops must be positioned
to exert impact force on the trolley side frames only.

Do not use this or any other overhead materials
handling equipment for lifting persons.

Stand clear of all loads and avoid moving a load over
the heads of any people. Warn any people of your
intention to move a load in their area.

Do not leave the load suspended in the air unattended.

Do not lower the hook to a point where the chain
becomes taut between the liftwheel and loose end
screw. (See Troubleshooting, Item 5C).

The Yale LH2 Hand Hoist and Yale Low Headroom
Trolley Hoist have been designed for manual
operation only.

Power operation may result in structural damage or
premature wear that may cause a part to break and
allow the load to fall.

To Avoid Injury:
Operate Yale LH2 Hand and Trolley Hoists using
hand power only.

To maintain continuous and satisfactory operation, a
regular inspection procedure must be initiated to
replace worn or damaged parts before they become
unsafe. Inspection intervals must be determined by
the individual application and are based on the type
of service to which your hoist will be subjected and
the degree of exposure to wear, deterioration or
malfunction of the critical components.

The type of service to which the hoist is subjected
can be classified as “Normal”, “Heavy” and “Severe”.

Normal Service: involves operation with randomly
distributed loads within the rated load limit, or
uniform loads less than 65% of rated load for not
more then 25% of the time.

Heavy Service: involves operating the hoist within
rated load limit which exceeds normal service.

Severe Service: is normal or heavy service with
abnormal operating conditions.

Following are the recommended, minimum intervals
of inspection. When the unit is subjected to extra
heavy usage or dusty, gritty, moist, or other adverse
atmospheric conditions, shorter time intervals must
be assigned. During the Periodic Inspection, inspection
must be made of all parts for unusual wear, corrosion
effect or damage in addition to those specifically
mentioned.

Before working on the hoist, review the disassembly
and assembly information on pages 8 through 13.

Minimum Inspection Schedule

Frequent Inspections: These inspections are

visual examinations by the operator or other des­ignated personnel. Records of such inspections are
not required. The frequent inspections are to be
performed monthly for normal service, weekly to
monthly for heavy service, and daily to weekly for
severe service and they should include those items
listed in Table 1.

Periodic Inspections: These inspections are visu­al inspections of external conditions by an appoint­ed person. Records of periodic inspections are to

be kept to provide the basis for continuing evalua­tion of the condition of the hoist.

Periodic inspections are to be performed yearly for
normal service, semi-annually for heavy service and
quarterly for severe service and they are to include
those items listed in Table 2.

Any parts that are deemed unserviceable are to be
replaced with new parts before the unit is returned
to service. It is very important that the unserviceable
parts be destroyed and properly disposed of to
prevent their possible future use as a repair item.

Any deficiencies are to be corrected before returning the
hoist to service. Operating a hoist with worn or damaged
parts or a malfunctioning hoist may result in serious
personal injury to the operator, nearby personnel and/or
property damage.

Also, the external conditions may show the need for dis­assembly to permit a more detailed inspection which, in
turn, may require the use of nondestructive type testing.

PREVENTIVE MAINTENANCE

In addition to the above inspection procedure, a preventive
maintenance program should be established to prolong
the useful life of the hoist and maintain its reliability and
continued safe use. The program should include the
periodic inspections with particular attention being paid
to the lubrication of various components using the
recommended lubricants.

HOOK INSPECTION

Hooks damaged from chemicals, deformation or
cracks, or that have more than a 10 degree twist
from the plane of the unbent hook or excessive
opening or seat wear must be replaced.

Also, on latch type hooks, hooks that are opened
and allow the latch to disengage the tip, must be
replaced.

Any hook that is twisted or has excessive throat
opening indicates abuse or overloading of the unit.
Other load sustaining components of the hoist
should be inspected for damage.

Check to assure latch is not damaged or bent and
that it operates properly with sufficient spring
pressure to keep the latch tightly against the tip of
the hook and allow the latch to spring back to the
tip when released. If the latch does not operate
properly, it should be replaced.

The charts below (Figures 7 and 8) should be used
to determine when the hook must be replaced.

LOAD CHAIN
Cleaning and Inspection

First clean the load chain with a non-acid or non-caustic
type solvent, then slack the chain and make a link-by-link
inspection for nicks, gouges, twisted links and excessive
wear or stretching. Worn chain should be gaged through­out its entire length and replaced if beyond serviceable
limits. Also, these chains are specially heat treated and
hardened and should never be repaired.

Using other than a Yale supplied load chain may
cause the chain to jam and this, in turn may break
the chain and allow the load to drop.

To Avoid Injury:

Use only Hoistaloy®load chain in the Yale LH2 Hand
and Low Headroom Trolley Hoists.

Gaging Load Chain Wear

To determine if the load chain should be continued in
service, check gage lengths as indicated in Figure 9.
Chain worn beyond length indicated, nicked, gouged
or twisted should be replaced before returning the
hoist to service. Chain should be clean, free of twists
and pulled taut before measuring. To aid in checking
