Safety Summary
WARNING
The National Safety Council, Accident Prevention Manual for
Industrial Operations, Eighth Edition and other recognized
safety sources make a common point: Employees who work
near cranes or assist in hooking on or arranging a load should be
instructed to keep out from under the load. From a safety
standpoint, one factor is paramount: conduct all lifting
operations in such a manner that if there were an equipment
failure, no personnel would be injured. This means keep out
from under a raised load and keep out of the line of force of any
load.
Ingersoll-Rand Material Handling hoists are manufactured in
accordance with the latest ASME B30.16 standards.
The Occupational Safety and Health Act of 1970, generally
places the burden of compliance with the user, not the
manufacturer. Many OSHA requirements are not concerned or
connected with the manufactured product but are, rather,
connected with the final installation. It is the owner’s and user’s
responsibility to determine the suitability of a product for any
particular use. It is recommended that all applicable industry,
trade association, federal, state and local regulations be checked.
Read all operating instructions and warnings before operation.
Rigging: It is the responsibility of the operator to exercise
caution, use common sense and be familiar with proper rigging
techniques. Refer to ASME B30.9 for rigging information,
American National Standards Institute, 1430 Broadway, New
York, NY 10018.
NOTICE
• Using other than genuine Ingersoll-Rand Material
Handling parts will void the warranty.
• Do not use this hoist for lifting, supporting, or transporting
people or lifting or supporting loads over people.
• Hoists are designed to provide a 4 to 1 safety factor. The
supporting structures and load-attaching devices used in
conjunction with this hoist must provide adequate support
to handle all hoist operations plus the weight of the hoist
and attached equipment. This is the customer’s
responsibility. If in doubt, consult a registered structural
engineer.
SAFE OPERATING INSTRUCTIONS
The following warnings and operating instructions have been
adapted in part from American National (Safety) Standard
ASME B30.16 (Overhead Hoists) and are intended to avoid
unsafe operating practices which might lead to injury or
property damage.
Ingersoll-Rand recognizes that most companies who use hoists
have a safety program in force in their plants. In the event you
are aware that some conflict exists between a rule set forth in
this publication and a similar rule already set by an individual
company, the more stringent of the two should take precedence.
Safe Operating Instructions are provided to make an operator
aware of dangerous practices to avoid and are not necessarily
limited to the following list. Refer to specific sections in the
manual for additional safety information.
1. Only allow personnel, trained in safety and operation of
this product, to operate the hoist.
2. Only operate a hoist if you are physically fit to do so.
3. When a “DO NOT OPERATE” sign is placed on the
hoist, do not operate the hoist until the sign has been
removed by designated personnel.
4. Before each shift, the operator should inspect the hoist for
wear or damage.
5. Never use a hoist which inspection indicates is worn or
damaged.
2
6. Periodically, inspect the hoist thoroughly and replace worn
or damaged parts.
7. Lubricate the hoist regularly.
8. Do not use hoist if hook latch has been sprung or broken.
9. Check that the hook latches are engaged before using.
10. Never splice a hoist chain by inserting a bolt between links.
11. Only lift loads less than or equal to the rated capacity of the
hoist. Refer to “SPECIFICATION” section.
12. When using two hoists to suspend one load, select two
hoists each having a rated capacity equal to or more than
the load. This provides adequate safety in the event of a
sudden load shift.
13. Never place your hand inside the throat area of a hook.
14. Never use the hoist load chain as a sling.
15. Never operate a hoist when the load is not centered under
the hook. Do not “side pull” or “yard.”
16. Never operate a hoist with twisted, kinked, “capsized” or
damaged load chain.
17. Do not force a chain or hook into place by hammering.
18. Never insert the point of the hook into a chain link.
19. Be certain the load is properly seated in the saddle of the
hook and the hook latch is engaged.

WARNING TAG
Each hoist is supplied from the factory with the safety tag
shown. If the tag is not attached to your unit, order a new tag
and install it. Refer to the parts list for the part number. Read
and obey all warnings and other safety information attached to
this hoist. Tag may be shown smaller than actual size.
INSTALLATION
Prior to installing the hoist, carefully inspect it for possible
shipping damage.
Hoists are supplied fully lubricated from the factory.
Lubrication of the load chain is recommended before initial
hoist operation.
CAUTION
• Owners and users are advised to examine specific, local or
other regulations, including American National Standards
Institute and/or OSHA Regulations which may apply to a
particular type of use of this product before installing or
putting hoist to use.
WARNING
• A falling load can cause injury or death. Before installing,
read “SAFETY INFORMATION”.
• Depending on the model selected, the hoist may weigh
more than 90 lbs. (41 kg). If parts of the hoist are dropped,
they can cause injury, death or property damage.
Adequately support the hoist during installation.
Hoists are designed to provide a 4 to 1 safety factor. The
supporting structures and load-attaching devices used in
conjunction with this hoist must provide adequate support to
handle all hoist operations plus the weight of the hoist and
attached equipment. This is the customer’s responsibility. If in
doubt, consult a registered structural engineer.
The MCH5 manual chain hoist must be used in a vertical
position to provide a straight line pull from top hook to bottom
hook. The hoist must be positioned so that it does not contact
the support members when in use. When operating in limited
areas suitable lifting attachments or slings must be used to
prevent the hoist body and hand chain from being obstructed.

Initial Operating Checks
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 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.
OPERATION
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.
The four most important aspects of hoist operation are:
1. Follow all safety instructions when operating the hoist.
2. Allow only people trained in safety and operation of this
hoist to operate the hoist.
3. Subject each hoist to a regular inspection and maintenance
procedure.
4. Be aware of the hoist capacity and weight of load at all
times.
WARNING
• Only allow personnel trained in safety and operation of
this hoist to operate the hoist.
• The hoist is not designed or suitable for lifting, lowering or
moving persons. Never lift loads over people.
INSPECTION
WARNING
• All new, altered or modified equipment should be
inspected and tested by personnel trained in safety,
operation and maintenance of this equipment to ensure safe
operation at rated specifications before placing equipment in
service.
Frequent and periodic inspections should be performed on
equipment in regular service. Frequent inspections are visual
examinations performed by operators or service personnel and
include observations made during routine equipment operation.
Periodic inspections are thorough inspections conducted by
personnel trained in the safety, operation and maintenance of
this equipment. ASME B30.16 states inspection intervals
depend upon the nature of the critical components of the
equipment 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.
Hoist Operation
When facing the hand chain side of the hoist:
Rotate hand chain clockwise to raise load.
Rotate 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.
Storing the Hoist
1. Always store the 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 Service in the “INSPECTION”
section.
Deficiencies revealed through inspection, or noted during
operation, must be reported to designated personnel trained in
safety, operation and maintenance of this equipment. 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 equipment 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.
NOTICE
• The external placement of coded marks on equipment
identifying completed inspections and operationally certified
equipment is an acceptable method of documenting periodic
inspections in place of written records.
