OPERATING INSTRUCTIONS

4

This manual contains important information to help you properly install, operate and
maintain your Series 622 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 file it for future reference.

The information herein is directed to the proper use, care and maintenance of the
Series 622 Hoist and does not comprise a handbook on the broad subject of rigging.

Rigging can be defined 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 622 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 verified
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 622 Hoists installed,
maintained and operated as outlined in this manual, and specifically excludes hoists
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-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 Indemnification 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.

WARNING

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.

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 firmly 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 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.

4. Do not load beyond the rated capacity of the hoist. Rated capacity can be
achieved with the following hand chain pulls:

Loose End
Pin

Upper Hook

Hoist Frame

Load Chain

Hand Chain

Loose End

Hook Latch
Lower Hook

To Raise Hook
Pull On This
Part of
Hand Chain

To Lower
Hook
Pull On This
Part of
Hand Chain

After mounting and before placing in service, check the hoist for proper operation.
Before operating the 3, 5, and 10 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.

WARNING

Exceeding the rated capacity of the hoist may cause load to fall.

TO AVOID INJURY:

Do not exceed the hand chain pulls specified in 4 above.

GENERAL INFORMATION

WARNING

Operating the 3, 5, and 10 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.

Operate the hoist with no load and then a light load of approximately 50 pounds (23
Kg.) times the number of load supporting chains to make sure it operates properly
and the brake holds the load when the hand chain is released; then operate with a
rated load as shown on the capacity plate.

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.

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.

WARNING

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.

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 classifications 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 deficiencies 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, 5 and 10 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.

MAINTENANCE

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 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.

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 figure 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).

13. Never operate the hoist when flammable materials or vapors are present.
Sharp contact between metal parts can produce sparks that can cause a fire
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 influence of drugs,
alcohol or medication causing diminished control.

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.

WARNING

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 622 Hoists using hand power only.

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 deficiencies 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.

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.

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.

WARNING

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 622 Hand Hois

t.

Before returning chain to service or after replacing a load chain, lubricate liberally
with Lubriplate Bar and Chain Oil 10-R (Fiske Bros. Refining 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

WARNING

The Lubricants used in and recommended for the Series 622 Hand Hoist may
contain hazardous materials that mandate specified 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. Refining Co.) or equal lubricant. Be sure the lubricant reaches the bearing sur­faces between the links. Remove excess oil from the chain.

WARNING

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.

WARNING

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, 5 and 10 ton); hook ball
bearings (3 and 5 ton); hook collar journals (3 and 5 ton); dead end stud (3,
5 and 10 ton); bearing surface of hook knob (10 ton); hook block pin (10
ton); and hanger pin (10 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. Refer to pages 8
and 10 for information on ordering the lubricants.

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:

2. 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 flats. Insert cotter pin and bend ends
to secure same.

TIMING
MARKS

2. The intermediate gears (622-8) 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, 5 and
10 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, 3, 5 and 10 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 (622-13) and down between the liftwheel and the
chain guide (622-16). Position the chain so that the first, as well as the third, link
stands on edge with the weld away from the liftwheel and the second link lays flat 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 (622-

15) 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 (622-5). Loop
the chain, making sure there are no twists, up to the loose end pin and slide the pin

B. 3 and 5 Ton Hoists

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 (first link
around the sheave must stand on edge) and up to the dead end block (622-26).
Secure chain to dead end block using the stud, nut and cotter pin. Refer to illustra­tion below.

through the last link of the chain. Slide the loose end pin into hole in the handwheel side
plate (622-4). 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.

WARNING

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.

10 Ton Hoist

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 20 feet (6M) long. Run the chain thru the hook block (first
link around the sheave must stand on edge) around the first hook block sheave, up
around the hanger sheave, down around the second hook block sheave and up to
the hoist hanger. Secure the chain to the hoist hanger using the dead end stud, nut
and cotter pin (622-38). Refer to Illustration below.

WARNING

TO AVOID INJURY:

Check each stage of reeving the chain to be sure it has no twists.

On the 3, 5 and 10 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.

EXTERIOR FINISH

The exterior surfaces of the hoists have a durable, scratch resistant finish. Normally,
the exterior surfaces can be cleaned by wiping with a cloth. However, if the finish 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.
Touch-up paint is only available in case quantities. See below for ordering informa­tion.

RECOMMENDED SPARE PARTS

To insure continued operation, it is recommended that two friction washers for each
Series 622 Hand Hoist in service, Key No. 622-39, be kept on hand at all times to
replace friction washers that are worn, contaminated or glazed. 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

The following information must accompany all correspondence or repair parts
orders.

1. Hoist Capacity

2. Serial Number -- stamped on the capacity label.
