Initial Operating Checks
CAUTION
• Ensure the hoist top hook is properly installed on the support
member and the hook latch is engaged.
Operate the hoist with a test load (10% of rated capacity) by
raising and lowering this load several times. Verify the brake
operation by lowering the same load to check load does not slip
when lowering stops.
NOTICE
• Each time a load is lifted, the operation of the load brake
should be checked by raising the load slightly and stopping to
ensure the brake will hold the load before proceeding to lift the
load.
Familiarize operators and people responsible for hoist installation
and service with ASME B30.16 specifications prior to placing the
unit into service. All the requirements of this specification,
including testing should be met before approving the hoist for
operation.
OPERATION
The four most important aspects of hoist operation are:
1. Follow all safety instructions when operating the hoist.
2. Allow only personnel trained in safety and operation of this
hoist to operate hoist.
3. Subject each hoist to a regular inspection and maintenance
procedure.
4. Be aware of hoist capacity and weight of load at all times.
WARNING
• Hoist is not designed or suitable for lifting, lowering or
moving persons. Never lift loads over people.
Hoist Operation
When facing hand chain side of hoist:
1. Pull down on the right hand chain (clockwise) to raise load.
2. Pull down on the left hand chain (counterclockwise) to lower
load.
NOTICE
• The clicking sound of the pawl on the ratchet gear is normal
when a load is being raised.
Slip Clutch Operation
Hoists are equipped with a slip clutch. When trying to lift a load
that exceeds capacity of hoist the hand chain will rotate in the
hoist body but the load will not be lifted.
It is important to keep the slip clutch properly adjusted. Refer to
the “MAINTENANCE” section on page 8 for the proper
procedure.
Storing the Hoist
1. Always store hoist in a no load condition.
2. Wipe off all dirt and water.
3. Oil the chain, hook pins and hook latch pins.
4. Hang in a dry place.
5. Before returning hoist to service follow instructions for
“Hoists Not in Regular Use” in the “INSPECTION” section
on page 5.
INSPECTION
WARNING
• All new, altered or modified hoists should be inspected and
tested by personnel trained in safety, operation and
maintenance of this hoist to ensure safe operation at rated
specifications before placing hoist in service.
Frequent and periodic inspections should be performed on hoists
in regular service. Frequent inspections are visual examinations
performed by operators or service personnel and include
observations made during routine hoist operation. Periodic
inspections are thorough inspections conducted by personnel
trained in the safety, operation and maintenance of this hoist.
ASME B30.16 states inspection intervals depend upon the nature
of the critical components of the hoist and the severity of usage.
Careful inspection on a regular basis will reveal potentially
dangerous conditions while still in the early stages, allowing
corrective action to be taken before the condition becomes
dangerous.
Deficiencies revealed through inspection, or noted during
operation, must be reported to designated personnel trained in
safety, operation and maintenance of this hoist. A determination as
to whether a condition constitutes a safety hazard must be decided,
and the correction of noted safety hazards accomplished and
documented by written report before placing the hoist in service.
Records and Reports
Inspection records, listing all points requiring periodic inspection
should be maintained for all load bearing equipment. Written
reports, based on severity of service, should be made on the
condition of critical parts as a method of documenting periodic
inspections. These reports should be dated, signed by the person
who performed the inspection, and kept on file where they are
readily available for review.
