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.
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.
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.

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.
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
Hoist 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.
When facing the hand chain side of the hoist:
Rotate hand chain clockwise to raise load.
Rotate hand chain counterclockwise to lower load.
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.
NOTICE
• The clicking sound of the pawl on the ratchet gear is
normal when a load is being raised.
WARNING
Storing the Hoist
• Only allow personnel trained in safety and operation of
this hoist to operate the hoist.
1. Always store the hoist in a no load condition.
2. Wipe off all dirt and water.
• The hoist is not designed or suitable for lifting, lowering or
moving persons. Never lift loads over people.
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.
INSPECTION
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.
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.
Records and Reports
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.
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
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.
• 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.

Load Chain Reports
Records should be maintained documenting the condition of
load chain removed from service as part of a long-range load
chain inspection program. Accurate records will establish a
relationship between visual observations noted during frequent
inspections and the actual condition of the load chain as
determined by periodic inspection methods.
Frequent Inspection
The Manual Chain Hoist should be inspected at the beginning of
each shift. Visual inspections should also be conducted during
regular service for any damage or evidence of malfunction
which appears between regular inspections.
1. OPERATION. Check for visual signs or abnormal noises
which could indicate a potential problem. Do not operate a
hoist unless the chain feeds through the hoist and hook
block smoothly. Listen for “clicking”, binding or
malfunctioning. The clicking sound of the pawl on the
ratchet gear is normal when a load is being raised. If chain
binds, jumps, or is excessively noisy, clean and lubricate
the chain. If problem persists, replace the chain. Do not
operate the hoist until all problems have been corrected.
Check that hand chain moves freely and without binding or
excessive drag. Hook should stop moving when hand chain
stops moving.
(Dwg. MHP0111)
3. HOOK LATCHES. Check operation of the hook latches.
Replace if broken or missing.
4. CHAIN. Refer to Dwg. MHP0102. Examine each of the
links for bending, cracks in weld areas or shoulders,
transverse nicks and gouges, weld splatter, corrosion pits,
striation (minute parallel lines) and chain wear, including
bearing surfaces between chain links. Replace a chain that
fails any of the inspections. Check lubrication and lubricate
if necessary. Refer to “Load Chain” under
2. HOOKS. Check for wear or damage, increased throat
width, bent shank or twisting of hook. Replace hooks
which exceed the throat opening discard width (15%)
shown in Table 2 (refer to Dwg. MHP0040) or exceed a
“LUBRICATION.”
°
10 twist (refer to Dwg. MHP0111). If the hook latch snaps
past the tip of the hook, the hook is sprung and must be
replaced. Check hook support bearings for lubrication and
damage. Make sure that they swivel easily and smoothly.
Repair or lubricate as necessary.
(Dwg. MHP0102)
CAUTION
• The full extent of chain wear cannot be determined by
visual inspection. At any indication of chain wear inspect
chain and load sheave in accordance with instructions in
“Periodic Inspection.”
(Dwg. MHP0040)
5. LOAD CHAIN REEVING. Make sure welds on standing
links are away from load sheave. Reinstall chain if
necessary. Make sure chain is not capsized, twisted or
kinked. Adjust as required.
Periodic Inspection
According to ASME B30.16, frequency of periodic inspection
depends on the severity of usage:
NORMAL
HEAVY
SEVERE
yearly
semiannually
quarterly
Disassembly may be required for HEAVY or SEVERE usage.
Keep accumulative written records of periodic inspections to
provide a basis for continuing evaluation. Inspect all items in
“Frequent Inspection.” Also inspect the following:
1. FASTENERS. Check rivets, capscrews, nuts, cotter pins
and other fasteners on hooks and hoist body. Replace if
missing and tighten or secure if loose.

2. ALL COMPONENTS. Inspect for wear, damage,
distortion, deformation and cleanliness. If external
evidence indicates the need, disassemble. Check gears,
shafts, bearings, sheaves, chain guides, springs and covers.
Replace worn or damaged parts. Clean, lubricate and
reassemble.
3. HOOKS. Inspect hooks for cracks. Use magnetic particle
or dye penetrant to check for cracks. Inspect hook retaining
parts. Tighten, repair or replace if necessary. Refer to the
latest edition of ASME B30.10 (Hooks) for additional hook
inspection information.
4. CHAIN SHEAVES. Check for damage or excessive wear.
Replace damaged parts.
5. BRAKE. Ensure proper operation. Brake should not slip
with test load ( rated capacity). If load test indicates the
need, disassemble. Brake discs must be free of excess oil,
any grease, unglazed, uniform in thickness and at least 5/64
in. (2 mm) thick. Check all other brake surfaces for wear,
deformation or foreign deposits. Inspect pawl brake. Teeth
of ratchet gear should be undamaged, and should stop gear
rotation in the counterclockwise direction. Check pawl
spring for damage. Clean and replace components as
necessary.
6. SUPPORTING STRUCTURE. If a permanent structure is
used inspect for continued ability to support load.
7. LABELS AND TAGS. Check for presence and legibility.
Replace if necessary.
8. END ANCHOR. Ensure end anchor on chain hoist is
engaged and unbent. Repair if damaged, replace if missing.
Refer to “Attaching End of Load Chain” in

General Disassembly
The following instructions provide the necessary information to
disassemble, inspect, repair, and assemble the hoist. Parts
drawings of the hoist assembly are provided in the Parts Section.
If a hoist is being completely disassembled for any reason,
follow the order of the topics as they are presented.
It is recommended that all maintenance work on the hoist be
performed on a bench.
In the process of disassembling the hoist, observe the following:
1. Never disassemble the hoist any further than is necessary to
accomplish the needed repair. A good part can be damaged
during the course of disassembly.
(Dwg. MHP0043)
2. Never use excessive force when removing parts. Tapping
gently around the perimeter of a cover or housing with a
soft hammer, for example, is sufficient to break the seal.

3. Do not heat a part with a flame to free it for removal unless
the part being heated is already worn or damaged beyond
repair and no additional damage will occur to other parts.
In general, the hoist is designed to permit easy disassembly
and assembly. The use of heat or excessive force should
not be required.
5. Polish the edges of all shaft shoulders to remove small
nicks which may have been caused during handling.
6. Remove all nicks and burrs caused by lockwashers.
Assembly
4. Keep the work area as clean as practical, to prevent dirt and
other foreign matter from getting into bearings or other
moving parts.
5. When grasping a part in a vise, always use leather-covered
or copper-covered vise jaws to protect the surface of the
part and help prevent distortion. This is particularly true of
threaded members, machined surfaces and housings.
6. Do not remove any part which is press fit in or on a
subassembly unless the removal of that part is necessary for
repairs or replacement.
CAUTION
• The brake will not operate properly if there is too much oil
on the brake discs (27 and 28). Excessive oil or grease on
brake components could cause the load to slip.
1. Dip replacement brake discs (27 and 28) in ISO VG32
hydraulic oil or SAE 10 oil for two seconds. Wipe off
excess oil.
2. Place brake disc B (28) over hub (26). Brake disc B (28)
has a smaller outside diameter than brake disc A (27).
3. Install ratchet gear (29) on hub (26) so recessed face fits
over brake disc B. Teeth of ratchet gear (29) must engage
pawl (24). Ratchet gear (29) should not rotate
counterclockwise and should “click” when rotating
clockwise.
4. Place brake disc A (27) on ratchet gear (29).
5. Place brake cover (30) over stay bolts on side plate 1
assembly (1).
6. With brake surface of handwheel (31) towards the brake
disc A (27), place handwheel (31) on pinion shaft (13).
Rotate handwheel (31) clockwise until clicking occurs.
Hold load chain (43) if necessary.

2. Remove hand chain (46) from hand wheel (31).
3. Remove cotter pin (34), unscrew pinion nut (33) and
remove washer (32).
4. Remove hand wheel (31) by holding the load chain (43)
and rotating hand wheel (31) counterclockwise until it can
be lifted off pinion shaft (13).
5. Remove brake cover (30) and brake disc A (27).
6. Remove ratchet gear (29) and brake disc B (28).
Cleaning, Inspection and Repair
Use the following procedures to clean and inspect the
components of the hoist.
7. Place washer (32) over pinion (13). Install pinion nut (33)
and cotter pin (34). Refer to “Brake Adjustment.”
8. Install hand chain (42) on handwheel (31). Make sure hand
chain (42) is seated properly.
Cleaning
9. Place wheel cover (35) over stay bolts. Install U-nuts (36).
Clean all hoist component parts in an acid free solvent (except
for the brake disc). The use of a stiff bristle brush will facilitate
the removal of accumulated dirt and sediments on the gears and
frames. Dry each part using low pressure, filtered compressed air.
Gears (14)
1/2, 1 and 2 ton units do not use gears with a circle.
On 1-1/2, 3 and 5 ton units, each hoist body must have one gear
without a “circle” and one gear with a “circle”. Refer to Dwg.
MHP0044.
Inspection
All disassembled parts should be inspected to determine their
fitness for continued use. Pay particular attention to the
following:
1. Inspect all gears for worn, cracked, or broken teeth.
2. Inspect shafts for ridges caused by wear. If ridges caused
by wear are apparent on shafts, replace the shaft.
3. Inspect all threaded items and replace those having
damaged threads.
4. Measure the thickness of the brake discs. If brake discs do
not have uniform thickness or are less than 5/64 in. (2 mm)
thick replace brake discs.
(Dwg. MHP0044)
NOTICE
Repair
• The 1/2 ton hoist has a center pinion gear with only 5 teeth.
Actual repairs are limited to the removal of small burrs and
other minor surface imperfections from gears and shafts. Use a
fine stone or emery cloth for this work.
1. Worn or damaged parts must be replaced. Refer to the
applicable parts listing for specific replacement parts
information.
2. Inspect all remaining parts for evidence of damage.
Replace or repair any part which is in questionable
condition. The cost of the part is often minor in comparison
with the cost of redoing the job.
3. Smooth out all nicks, burrs, or galled spots on shafts,
bores, pins, and bushings.
4. Examine all gear teeth carefully, and remove nicks and
burrs.

2. If you are replacing the hand chain, disconnect it at the “C”
link and carefully remove the hand chain.
Hand Chain Adjustment or Replacement
3. When replacing a hand chain, cut a length 2 times the
required hand chain drop plus about one foot (305 mm).
For adjustments, remove or add a length of chain twice the
difference in hand chain height. To prevent the hand chain
from twisting, maintain an even number of links, by
removing or adding an even number of links.
4. If you are replacing the hand chain, run the new hand chain
up through the left hand chain guide, around the handwheel,
making sure the hand chain is seated in the handwheel
pockets, and back down through the right hand chain guide.
5. Connect the hand chain ends with the “C” link(s), making
the total number of links even, and bend the “C” link(s)
shut.
CAUTION
• When cutting the weld side of a hand chain link, do not cut
or nick the opposite side. A damaged link must be replaced
to prevent premature failure. A falling hand chain could
cause injury.
6. Make sure the hand chain is not twisted. If twisted, untwist
or open a “C” link and remove one hand chain link if
necessary.
(Dwg. MHP0016)
Load Test
Prior to initial use, all new, extensively repaired, or altered
hoists shall be load tested by or under the direction of a person
trained in the operation and maintenance of this hoist, and a
written report furnished confirming the rating of the hoist. Test
hoist to 125% of its rated capacity. Testing to more than 125%
may be necessary to comply with standards and regulations set
forth in areas outside of the USA.

WARRANTY
LIMITED WARRANTY
IMPORTAND NOTICE
Ingersoll-Rand Company (I-R) warrants to the original user its
Hoists and Winches (Products) to be free of defects in material
and workmanship for a period of one year from the date of
purchase. I-R will repair, without cost, any Product found to be
defective, including parts and labor charges, or at its option, will
replace such Products or refund the purchase price less a
reasonable allowance for depreciation, in exchange for the
Product. Repairs or replacements are warranted for the
remainder of the original warranty period.
It is our policy to promote safe delivery of all orders.
This shipment has been thoroughly checked, packed and
inspected before leaving our plant and receipt for it in good
condition has been received from the carrier. Any loss or
damage which occurs to this shipment while enroute is not due
to any action or conduct of the manufacturer.
VISIBLE LOSS OR DAMAGE
If any of the goods called for on the bill of lading or express
receipt are damaged or the quantity is short, do not accept them
until the freight or express agent makes an appropriate notation
on your freight bill or express receipt.
If any Product proves defective within its original one year
warranty period, it should be returned to any Authorized Hoist
and Winch Service Distributor, transportation prepaid with
proof of purchase or warranty card.
CONCEALED LOSS OR DAMAGE
This warranty does not apply to Products which I-R has
determined to have been misused or abused, improperly
maintained by the user, or where the malfunction or defect can
be attributed to the use of non-genuine I-R parts.
When a shipment has been delivered to you in apparent good
condition, but upon opening the crate or container, loss or
damage has taken place while in transit, notify the carrier’s
agent immediately.
I-R makes no other warranty, and all implied warranties
including any warranty of merchantability or fitness for a
particular purpose are limited to the duration of the
expressed warranty period as set forth above. I-R’s
maximum liability is limited to the purchase price of the
Product and in no event shall I-R be liable for any
consequential, indirect, incidental, or special damages of any
nature rising from the sale or use of the Product, whether
based on contract, tort, or otherwise.
DAMAGE CLAIMS
You must file claims for damage with the carrier. It is the
transportation company’s responsibility to reimburse you for
repair or replacement of goods damaged in shipment. Claims for
loss or damage in shipment must not be deducted from the
Ingersoll-Rand invoice, nor should payment of Ingersoll-Rand
invoice be withheld awaiting adjustment of such claims as the
carrier guarantees safe delivery.
You may return products damaged in shipment to us for repair,
which services will be for your account and form your basis for
claim against the carrier.
Note: Some states do not allow limitations on incidental or
consequential damages or how long an implied warranty lasts so
that the above limitations may not apply to you.
This warranty gives you specific legal rights and you may also
have other rights which may vary from state to state.
