GENERAL INFORMATION
This manual contains important information to help you properly
install, operate and maintain your Series 622A Hoist for maximum
performance, economy and safety.
Please study its contents thoroughly before putting your hoist
into operation. By practicing correct operating procedures and by
carrying out the recommended preventive maintenance suggestions,
you will be assured of long, dependable and safe service. After
you have completely familiarized yourself with the contents of this
manual, we recommend that you carefully le it for future reference.
The information herein is directed to the proper use, care and
maintenance of the Series 622A Hoist and does not comprise a
handbook on the broad subject of rigging.
Rigging can be dened as the process of lifting and moving heavy
loads using hoists and other mechanical equipment. Skill acquired
through specialized experience and study is essential to safe rigging
operations. For rigging information, we recommend consulting a
standard textbook on the subject.
CM REPAIR/REPLACEMENT POLICY
All Columbus McKinnon (CM) Series 622A Hoists are inspected and
performance tested prior to shipment. If any properly maintained
hoist develops a performance problem, within one year of shipment,
due to a material or workmanship defect, as veried by CM, repair
or replacement of the unit will be made to the original purchaser
without charge. This repair/replacement policy applies only to Series
622A Hoists installed, maintained and operated as outlined in this
manual, and specically excludes hoists subject to normal wear,
abuse, improper installation, improper or inadequate maintenance,
hostile environmental effects and unauthorized repairs/modications.
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-CM replacement parts voids
the guarantee and could lead to dangerous operation. For full Terms
of Sale, see Sales Order Acknowledg-ment. Also, refer to the back
cover for Limitations of Warranties, Remedies and Damages, and
Indemnication and Safe Operation.
UNPACKING
After opening the carton, the hoist should be carefully inspected
for damage which may have occurred during shipment or handling.
Check the hoist frame for dents or cracks and inspect the load chain
for nicks and gouges. If shipping damage has occurred, refer to the
packing list envelope on the carton for claim procedure.
OPERATING INSTRUCTIONS
After mounting and before placing in service, check the hoist for
proper operation. Before operating the 3 and 5 ton units, make
sure that all strands of chain are straight and have no twists (due to
capsized hook). If the chain is twisted, reverse capsize. To operate
the hoist, pull on the hand chain as indicated below.

ENGLISH
Operating a unit with obvious external damage may cause load to
drop and that may result in personal injury and/or property damage.
TO AVOID INJURY:
Carefully check unit for external damage prior to installation.
Operating the 3 and 5 ton hoists in the lifting direction with the hook
block in contact with the frame and/or hoist hanger may break the
chain and allow the load to drop.
TO AVOID INJURY:
Stop operating in the lifting direction when the hook block
contacts the hoist frame and/or hanger, as noted by sudden
increase in hand chain pull or tipping of the hook block.
SAFETY PROCEDURES
1. The hoist 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 be
allowed to bear on any support when in use as this would
cause bending of the hook or frame and damage the unit.
2. When preparing to lift or move a load, be sure that the
attachments to both hooks are rmly seated in the saddles
of the hooks. Avoid off center loading of any kind especially
loading on the tip of the hook. Also observe that the chain
hangs straight (without twist) from hoist to lower hook.
3. When lifting, raise the load only enough to clear the oor or
support, and check to be sure brake will hold load and that
attachments to the load are rmly seated. Continue the lift only
after you are assured the load is free of all obstructions.
4. Do not load beyond the rated capacity of the hoist.
Rated capacity can be achieved with the following
hard chain pulls:

2 (2000) 103 (47)
3 (3000) 77 (35)
5 (5000) 86 (39)
Since these hand chain pulls can easily be applied by one person,
under no circumstances should more than one person operate the hoist
hand chain. Overloading can cause immediate failure of some load
carrying parts or result in damage causing future failure at less than
rated capacity. When in doubt, use the next larger capacity CM hoist.
Exceeding the rated capacity of the hoist may cause load to fall.
TO AVOID INJURY:
Do not exceed the hand chain pulls specied in 4 above.
5. 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 mean twisted chain and
a jammed liftwheel. The chain could be damaged at the hook.
6. Stand clear of all loads and avoid moving a load over the heads
of other personnel. Warn personnel of your intention to move a
load in their area.
7. Do not leave the load in the air unattended.
8. Do not lower the hook to a point where the chain becomes taut
between the liftwheel and loose end pin.
9. Do not run the lower hook block into the hoist frame. Frame
and/or chain guide damage may result.
10. The hoist has 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 Series 622A Hoists using hand power only.
11. Do not use this or any other overhead materials handling
equipment for lifting persons.
12. Do not allow the load to bear against the hook latch. The latch
is to help maintain the hook in position while the chain is slack
before taking up slack chain.
Allowing the load to bear against the hook latch and/or hook tip can
result in loss of load.
TO AVOID INJURY:
Do not allow the load to bear against the hook latch and/or hook
tip. Apply load to hook bowl or saddle only.
13. Never operate the hoist when ammable materials or vapors
are present. Sharp contact between metal parts can produce
sparks that can cause a re or explosion.
14. STAY ALERT! Watch what you are doing and use common
sense. Do not use the hoist when you are tired, distracted or
under the inuence of drugs, alcohol or medication causing
diminished control.

MAINTANCE
INSPECTION
To maintain continuous and satisfactory operation, a regular
inspection procedure must be initiated so that worn or damaged
parts can be replaced before they become unsafe. The intervals of
inspection must be determined by the individual application and are
based upon the type of service to which the hoist will be subjected.
The inspection of hoists is divided into two general classications
designated as “frequent” and “periodic.”
FREQUENT INSPECTIONS:
These inspections are usually visual examinations by the operator
or other designated personnel. The frequent inspections are to be
performed daily or monthly and shall include the following items:
a. Braking mechanisms for evidence of slippage — daily.
b. Load Chain for lubricant, wear, damaged links or foreign
material — daily. See below.
c. Hooks for damage, cracks, twists, latch engagement and latch
operation — monthly. See below.
Any deciencies noted are to be corrected before the hoist is
returned to service.
PERIODIC INSPECTIONS:
These are visual inspections by an appointed person who makes
records of apparent external conditions to provide the basis for a
continuing evaluation. For normal service, the periodic inspections
are to be performed yearly and for heavy service, the periodic
inspections are to be performed semi-annually.
Due to the construction of the hoist, it will be necessary to partially
disassemble the unit to perform the periodic inspections. The
periodic inspections are to include those items listed under frequent
inspections as well as the following:
a. Chain for excessive wear or stretch. See below.
b. Worn, cracked or distorted parts such as hook blocks, hoist
hanger, chain guide, stripper, loose end pin, shafts, gears, hook
collar and bearings.
c. Inspect for wear on the tip of the pawl, teeth of the ratchet and
pockets of the liftwheel and handwheel.
d. Loose or missing bolts, nuts, pins or rivets.
e. Inspect brake components for worn, glazed or contaminated
friction discs and scoring of the handwheel hub, ratchet and
friction hub. Replace friction discs if the thickness is less than
0.044 in. (1.12 mm) on 1/2 & 1 ton units and 0.059 in. (1.50 mm)
on 2, 3 and 5 ton units.
f. Corroded, stretched or broken pawl spring.
g. Free movement of the pawl on the pawl stud. Also, apply a
thin coat of lubricant to the pawl stud (see page 6) before
reassembling the unit.
h. Hooks — dye penetrant, magnetic particle or other suitable
crack-detecting inspections should be performed at least once
a year, if external conditions indicate there has been unusual
usage.
Any deciencies noted are to be corrected before the hoist is
returned to service. Also, the external conditions may show the need
for more detailed inspection which, in turn, may require the use of
nondestructive-type testing.
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 to prevent possible future
use as a repair item and properly disposed of.

HOOK INSPECTION
Hooks damaged from chemicals, deformations or cracks or that
have more than a 10° twist from the plane of the unbent hook or
excessive opening or seat wear must be replaced.
Also, hooks that are opened and those that 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.
The chart below should be used to determine when the hook must
be replaced. To measure throat opening, depress the latch against
the hook body as shown below.

Also, check to make sure that the latch is not damaged or bent and
that it operates properly with sufcient 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.
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.
To determine if load chain should be continued in service, check
gage lengths as indicated in gure below. Chain worn beyond length
indicated, nicked, gouged or twisted should be replaced before
returning hoist to service. Chain should be clean, free of twists and
pulled taut before measuring. In cases where the wear is localized
and not beyond serviceable limits, it is sometimes possible to
reverse the load chain, end for end, and allow a new section to take
the wear. Proper installation of the load chain is covered in section
on Reeving Load Chain (page 7).

Note that worn chain can be an indication of worn hoist
components. For this reason, the hoist’s chain guide roller and
liftwheel should be examined for wear and replaced as necessary
when replacing worn chain.
Also, load chains are specially heat treated and hardened and should
never be repaired.
Using other than CM-supplied load chain may cause the chain to
jam in the hoist and/or allow the chain to break and the load to drop.
TO AVOID INJURY:
Due to the size requirements and physical properties, use only
CM Hoistaloy
®
load chain in the Series 622A Hand Hoist.
IMPORTANT: Do not use replaced chain for other purposes such
as lifting or pulling. Load chain may break suddenly without
visual deformation. For this reason, cut replaced chain into short
lengths to prevent use after disposal.
Before returning chain to service or after replacing a load chain,
lubricate liberally with Lubriplate Bar and Chain Oil 10-R (Fiske Bros.
Rening Co.) or equal lubricant. Remove excess lubricant from the
chain by wiping with a cloth.
HAND CHAIN
Hand chain should be cleaned, inspected and gaged in the same
manner as load chain.
As received from the factory, the hand chain contains an unwelded
link. This link can be placed in a vise and twisted open to facilitate
changing chain length. Please note that opening and closing of
the connecting link more than twice is not recommended. Also,
connecting links must not be made by cutting the weld side of a
standard hand chain link.
Hand chain should be assembled to handwheel free from twists with
weld on vertical link facing inwards towards handwheel and weld on
horizontal link facing towards the handwheel side plate.
Care must be taken to assure that there is no twist in the
hand chain loop.
LUBRICATION
The Lubricants used in and recommended for the Series 622A Hand
Hoist may contain hazardous materials that mandate specied
handling and diposal procedures.
AVOID CONTACT AND CONTAMINATION:
Handle and dispose of lubricants only as directed in applicable
material safety data sheets and in accordance with applicable
local, state and federal regulations.
Lubricate load chain with a light coat of Lubriplate Bar and Chain
Oil 10-R (Fiske Bros. Rening Co.) or equal lubricant. Be sure the
lubricant reaches the bearing surfaces between the links. Remove
excess oil from the chain.

(ENGLISH)
Manual P/N: 192052171 Rev AA May 2018
ENGLISH
Used motor oils contain unknown carcinogenic materials.
TO AVOID HEALTH PROBLEMS:
Never use used motor oils as a chain lubricant. Only use Lubriplate
Bar and Chain Oil 10-R as a lubricant for the load chain.
The hoist normally requires no additional lubrication, except for
periodically lubricating the load chain as indicated above or when
the unit is disassembled for periodic inspections, cleaning or repairs.
The brake is designed to operate dry. Do not use any grease
or lubricant on the braking surfaces. When lubricating parts
adjacent to the brake, do not use an excessive amount of
lubricant which could seep onto the brake surfaces.
Using any grease or lubricant on the braking surfaces will cause
brake slippage and loss of load control which may result in injury
and/or property damage.
TO AVOID INJURY:
Do not use any grease or lubricant on braking surfaces. The brake is
designed to operate dry.
When the hoist is disassembled for periodic inspections, check the
pawl for free movement and apply a light coat of WD-40 (WD-40 Co.)
lubricant to the pawl stud.
When the hoist is disassembled for cleaning or repairs, the following
locations should be lubricated using approximately 1 oz. (29.5mL)
per hoist of Molykote BR-2-S (Dow Corning Corp.) grease or
equivalent—threads of handwheel; gears; liftwheel rollers; gear
bearing rollers; journals of chain guide and dead end pin; sheave
wheel rollers (3 and 5 ton); hook ball bearings (3 and 5 ton); hook
collar journals (3 and 5 ton); dead end stud (3 and 5 ton).
NOTE: To assure extra long life and top performance, be sure
to lubricate the various parts of the hoist using the lubricants
specified above. If desired, these lubricants may be purchased
from CM.

The latch is secured to the hook (upper and lower) by a rivet. To
remove the latch, it is necessary to remove the head of the rivet by
grinding or drilling. For replacement of the latch, refer to paragraph
4 of the Assembly Instructions.
ASSEMBLY
Consideration must be given to the following when assembling the
hoist:
1. Assemble the brake components as shown below. The ratchet
teeth must face as shown and engage the pawl. Do not
lubricate the brake surfaces. The brake operates dry. Assemble
handwheel to pinion shaft and turn handwheel to seat brake
components. Assemble the pinion shaft nut to the shaft until
the nut bottoms. Then back nut off at least one but not more
than two ats. Insert cotter pin and bend ends to secure same.

DISASSEMBLY
Two points of caution to be observed in disassembly are:
1. Loose rollers and bearing balls are used in various locations
in the units. Care must be taken so as to not lose or misplace
these since they may drop from the unit as the various parts are
disassembled. The number of rollers or bearing balls used are:

* 1/2 ton hoist has two pawls 180° apart.
2. The intermediate gears have timing marks (letter “O” stamped
on one tooth). The gears must be assembled with these marks
orientated as shown below.
3. For proper operation, the correct number of rollers must be
installed at the rotating points of the liftwheel, intermediate
gears, hook block sheave (3 and 5 ton) and hoist hanger sheave
(10 ton). Also, on the 3 and 5 ton units, the correct number
of bearing balls must be installed in the hook collar to retain
the hook and insure proper loading. Refer to Disassembly
Instructions above for the number of rollers at these locations.
Applying grease, Molykote BR - 2 - S (Dow Corning Corp.) or
equal EP grease, to the rollers or bearing balls will help hold
them in position during assembly.

4. When assembling the latch to the hook, the end of the rivet
must be peened over. When peening over the rivet, only apply
enough force to form the head and retain the rivet. Excessive
force will deform the latch and make the latch inoperable.
REEVING LOAD CHAIN
A. 1/2, 1, 2 (SINGLE REEVE) TON HOISTS
Attach approximately 20”(508mm) of soft wire to the loose end of the
chain. Pass the wire over the top of the liftwheel and down between
the liftwheel and the chain guide. Position the chain so that the rst,
as well as the third, link stands on edge with the weld away from the
liftwheel and the second link lays at on the liftwheel. After the chain
has been started, pull hand chain in the hoisting direction until about
2 feet (0.6M) of chain has passed over the liftwheel. The wire should
now be removed from the chain. Remove the cotter pin from the
loose end pin and slide the loose end pin to the side into the gear
housing, leaving approximately 1/2”(12.7mm) of the pin protruding
from the geared side plate. Loop the chain, making sure there are no
twists, up to the loose end pin and slide the pin through the last link
of the chain. Slide the loose end pin into hole in the handwheel side
plate until the cotter pin hole is visible. Secure the loose end pin by
reinstalling the cotter pin and spreading the legs of the cotter pin.

ENGLISH
LIFTWHEEL
LOOSE END PIN
Failure to properly install the load chain between chain guide and
liftwheel may cause the chain to lift out of the liftwheel pockets and
allow the load to drop.
TO AVOID INJURY:
Feed load chain between liftwheel and chain guide, as shown above,
before attaching it to the loose end pin..
B. 2 (DOUBLE-REEVE), 3 AND 5 TON
The load chain must have an odd number of links. After attaching
the chain to the loose end pin per above, operate in the hoisting
direction until the load end of the chain is approximately 5 feet
(1.5M ) long. Run chain thru the hook block (rst link around the
sheave must stand on edge) and up to the dead end block.
Secure chain to dead end block using the stud, nut and cotter
pin. Refer to illustration below.
On the 3 and 5 ton units, twisted load chain will cause the chain to
jam in the liftwheel or sheave wheels and this may break the chain
and allow the load to drop.
TO AVOID INJURY:
Check each stage of reeving the chain to be sure it has no twists.
REEVING
3 AND 5-TON HOIST
EXTERIOR FINISH
The exterior surfaces of the hoists have a durable, scratch resistant
nish. Normally, the exterior surfaces can be cleaned by wiping with
a cloth. However, if the nish is damaged, compatible touch-up
paint can be purchased from CM. Order one case (12-12 oz.-354mL
aerosol cans) of orange touch-up paint Part Number 84190. Touchup paint is only available in case quantities. See below for ordering
information.
PREVENTIVE MAINTENANCE
In addition to the periodic inspection procedure, a preventive
maintenance program should be established to prolong the useful
life of the hoist and maintain its dependability 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.
TESTING
Before using, all altered, repaired or used hoists that have not been
operated for the previous 12 months should be tested by the user for
proper operation. First, test the unit without a load and then with a
light load of 50 pounds (23Kg.) times the number of load supporting
chains to be sure that the hoist operates properly and that the brake
holds the load when the hand chain is released. Next test with a
load of 125% of rated capacity. In addition, hoists in which load
sustaining parts have been replaced should be tested with 125% of
rated capacity by or under the direction of an appointed person and
written report prepared for record purposes.
NOTE: For additional information on inspection and testing, refer
to Code B30.16 “Overhead Hoists” obtainable from ASME Order
Department, 22 Law
