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 specified 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 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.
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 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 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 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.
