GENERAL INFORMATION

The ShopAir Hoists are precision, air operated link type chain
hoists that are available in five rated capacities: 250, 300, 500
600 and 1000 pounds (113, 136, 226, 272 and 453 kg.). Each
unit is supplied with a pendant throttle control station for
controlling the lifting and lowering speeds and an upper latch
type hook for suspending the hoist from a fixed support or
trolley.

The basic design of the ShopAir consists of a lightweight,
rugged aluminum alloy frame which houses a vane type air
motor, hardened steel gears, hardened steel oblique lay
liftwheel, a disc type load brake and a muffler for quiet
operation. The gearing includes a Protector™ that is a
factory set clutch that prevents lifting dangerous overloads.
The lifting medium is alloy, hardened steel link type chain
and it connects the lower hook to the liftwheel. The hoists
with rated capacity of 250, 300 and 500 pounds (113, 136
and 226 kg.) are single reeved units whereas the units with
rated capacities of 500, 600 and 1000 pounds (226, 272 and
453 kg.) are double reeved units. The standard lift of each
capacity is 10 feet (3 meters) and units with longer lifts can
be provided on a special, per order basis.

The pendant throttle control is suspended from the hoist
frame so that the control levers are approximately four feet
(1.2 meters) above the lower hook when it is in its lowest
position. A unique, three tube hose is provided between the
throttle control and the hoist head to control the vane type air
motor and the lifting speed. The three tube hose includes an
internal, aircraft type wire rope to eliminate strain on the hose
connections at the throttle control and at the hoist head.

A quick connect type fitting is provided at the air inlet to easily
attach the hoist to the external air supply (refer to
INSTALLATION on page 3). At installation, there are no
adjustments to be made. Just connect the hoist to the external
air supply and the ShopAir Hoist is ready for operation.

REPAIR/REPLACEMENT POLICY

All Columbus McKinnon (CM®) ShopAir Chain Hoists are
inspected and performance tested prior to shipment. If any
properly maintained hoist develops a performance problem,
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 ShopAir 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.

Alterations or modification of hoist and use of non­original repair parts can lead to dangerous operation
and injury.

TO AVOID INJURY:

• Do not alter or modify equipment.

• Do use only original replacement parts.

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 Acknowledgment. Also, refer to the back cover for
Limitations of Warranties, Remedies and Damages, and
Indemnification and Safe Operation.

INSTALLATION

UNPACKING

After opening the carton, carefully inspect the hoist frame,
control tube, hooks and pendant throttle control for damage
that may have occurred during shipment. If there is
damage, refer to the packing slip envelope.

Operating the hoist 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 hoist for external damage prior to
installation.

All hoists are completely assembled, lubricated and load
tested prior to shipment. To place the hoist in service,
attach the upper hook to a support or trolley that has
sufficient strength to support the hoist and several times
the rated capacity of the hoist. If in doubt, consult a
registered engineer and local building code.

Be certain that the upper hook is attached to the support
so that the support is firmly seated in the center of hook
bowl, the latch closes and contacts the tip of the hook, and
that the latch does not bear against the support.

Suspending the hoist from an inadequate support may
allow the hoist and load to fall and cause injury and/or
property damage.

TO AVOID INJURY:

Make sure the structure has sufficient strength to hold
several times the hoist and its rated load. Using the
upper hook, hang the hoist from the support.

AIR SUPPLY SYSTEM

Connect hoist to a filtered and lubricated air source using a
1/2” (12.7 mm.) I.D. hose (see Figure 3). Do not use
smaller diameter hose, since it will restrict air flow and
reduce hoist performance. If the hoist is suspended from a
trolley, provide sufficient hose to reach from the source to
the farthest point of trolley travel. CM®Hose Trolleys are
recommended to keep the hose up and out of the way.

A filter and lubricator (see Figure 3)
be

tween the air source and the air hose leading to the hoist.
These keep the air flowing free from dirt and add lubricant
to the air so internal parts of the motor are constantly
lubricated. Use a good grade of oil with a viscosity of 180
SSU at 100

0

F., air powered tool oil or SAE 0W machine oil.

Figure 3 Air Filter and Lubricator Unit

The recommended operating air pressure for the hoist is 90
psig. When line pressure exceeds 100 psig (at the hoist
when it is lifting rated load), it is recommended that a
pressure regulator be provided in the air supply line to keep
the pressure at 90 psig. Although there is a wide range of
pressures within which the hoist will operate, motor efficiency
decreases as the air pressure drops (refer to the following
Chart).

strands of chain together. With no load on the lower hook,
depress the UP () lever in the pendant throttle control and
raise the lower hook until it is about 2 feet (0.61 M) below the
bottom of the hoist. Check both strands of chains for twists.
Twists occur if the lower hook block has been capsized
between the strands of chain during packing, shipment
and/or handling. Reverse the capsize to remove twists.

CHAIN CONTAINER

If the chain container is to be used, attach it to the hoist
per the instructions provided.

OPERATING INSTRUCTIONS

The hoist is equipped with a Protector™ that is designed to
allow the first gear to slip when it is attempted to lift an
excessive overload. An overload is indicated when the
hoist speed slows down, it raises the load in a jerky
manner or if it will not lift the load at all. In addition, some
clutching noise may be heard. Should this occur,
immediately release the UP () lever to stop the operation
of the hoist and reduce the load to the rated capacity of
the hoist. When the excessive load is removed, normal
operation of the hoist is automatically restored.

of ambient temperatures (above 150

0

F., -90C.), changes in lubricant properties may permit

15
the hoist to raise larger loads than under operating
temperatures and could present possibility of property
damage or injury. Hoist operation is controlled by
depressing the pendant throttle control levers. Depressing
the UP () lever will move the lower hook towards the hoist
and depressing the DOWN () lever will move the lower
hook away from the hoist. The speed of lifting and lowering
can be varied by the distance the lever is depressed. To
stop lifting and lowering, release the lever. The up and down
levers are momentary type and the hoist will operate in the
selected direction as long as the lever is held in the
depressed direction. Release the lever and the hoist will
stop.

5. Stand clear of all loads and avoid moving loads over
heads of other personnel. Warn personnel of your
intention to move a load into their area.

6. Do not leave the load suspended in air unattended.

7. Permit only qualified personnel to operate this hoist.

8. Do not wrap the load chain around the load and hook
onto itself as a choker chain. Doing so will result in:

• The loss of the swiveling effect of the hook which could

cause twisted chain and jammed liftwheel.

• The chain could be damaged at the hook.

9. On the 500, 600 and 1000 pound (226, 272 and 453 Kg.)
double reeved units, check for twists in the load chain. A
twist can occur if the lower hook block has been
capsized between the strands of chain. Reverse the
capsize to remove twist.

10.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 the 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 a load to bear against the hook latch and/or
the hook tip. Apply load to hook bowl or saddle only.

11.Take up slack load chain carefully and start load easily
to avoid shock and jerking of the chain. If there is any
evidence of overloading, immediately lower the load
and remove the excess load.

12.Do not allow the load to swing or twist while hoisting.

13.Never operate the hoist when flammable materials or
vapors are present. Contact between steel parts may
produce sparks that in turn can cause a fire or

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. Frequent
inspections are to be performed daily or monthly and shall
include the following items:

a. Operate the hoist, with no load, and check for visual

signs or abnormal noises which could indicate a

potential problem - daily.
b. Brake for evidence of slippage - daily.
c. Chain for lubricant, wear, damaged links or foreign

material - daily (see below).
d. Hooks for damage, cracks, twist, latch engagement

and latch operation - daily (see below).

Any deficiencies must be corrected before the hoist is
returned to service.

PPeerriiooddiicc IInnssppeeccttiioonnss

These are

cords apparent external conditions to provide a basis for

re
continuing evaluation. Periodic inspections are to be
performed semi-annually and they should include the
following:

liftwheel or sheave (double reeved unit). Widening and

deepening of pockets may cause chain to lift-up in the

pockets and cause binding between liftwheel and

chain guide or between lower sheave and hook block.

Check chain guide for wear or burring where the chain

enters the hoist. Severely worn or damaged parts

should be replaced.

e. External evidence of excessive wear of brake parts -

see page 7.

f. Check the control station levers to make sure they

operate freely and spring back when released.

g. Check air supply hose and control hose for kinks, cuts,

leaks and damage.

h. Check the chain pin or dead end pin and chain stop

for wear and cracks.

i. Check for lubricant leaks at gasket between main

frame and gear housing. Tighten gear housing screws
to stop leak. If leak persists, replace gasket.

j. Inspect splines on first pinion shaft and motor coupling

for signs of wear or deterioration. Replace splined
parts if worn or damaged.

k. Check for air leaks at brake end cap. Replace piston

seals to stop leaks.

l. Check for air leaks at the joints of the motor. Tighten

screws to stop leaks. If leaks persist, disassemble
motor, see page 8, and replace seals.

m. Check for air leaks at joint between the supply block

and valve body. Tighten screws or replace gasket to
stop leaks.

n. Check for air leaks at o-rings on top and under valve

body. Tighten valve bolt or replace o-ring to stop leaks.

Any deficienci

es

noted must 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.

Hook Inspection

Hook damage from chemicals, deformations or cracks or
that have more than a 10

0

twist from the plane of the

unbent hook or excessive opening must be replaced.

Any hook that is twisted or has excessive throat opening
indicates abuse or overloading of the unit. Other load­sustaining components of the hoist should be inspected
for damage.

On latch type hooks, 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. See below to determine when the
hook must be replaced.

LOAD CHAIN

Chain should feed smoothly into and away from the hoist
or hook block (500, 600 and 1000#, 226, 272 and 453 Kg.
units). If chain binds, jumps or is noisy, first clean and
lubricate it (see below). If trouble persists, inspect chain
and mating parts for wear, distortion or other damage.

Chain Inspection

First clean chain with a non-caustic/non-acid type solvent
and make a link by link inspection for nicks, gouges,
twisted links, weld spatter, corrosion pits, sitriations
(minute parallel lines), cracks in weld areas, wear and
stretching. Chain with any one of these defects must be
replaced.

Slack the portion of the chain that normally passes over
the liftwheel. Examine the interlink area for the point of
maximum wear (polishing, see figure 5). Measure and
record the stock diameter at this point of the link. Then
measure stock diameter in the same area on a link that
does not pass over the liftwheel (use the link adjacent to
the loose end link for this purpose). Compare these two
measurements. If the stock diameter of the worn link is

0.010 inches (0.254 mm.), or more, less than the stock
diameter of the unworn link, the chain must be replaced.

FFiigguurree 55.. CChhaaiinn WWeeaarr AArreeaass

On the 500, 600 and 1000# (226, 272 and 453 Kg.) units,
repeat this examination of the chain that passes through the
hook block.

Also check chain for stretch using a vernier caliper as
shown in figure 6. Select an unused, unstretched section
of chain (usually at the loose end) and measure and
record the length over 11 chain links (pitches). Measure
and record the same length on a worn section of chain.
Obtain the amount of stretch and wear by subtracting the
measurement of the unworn section from the measurement
of the worn section. If the result (amount of stretch and
wear) is greater than 0.145 inch (3.7 mm.), the chain must
be replaced.

Use only a “Knife-edge” caliper to eliminate possibility of
false reading by not measuring full pitch length.

Note that worn chain can be an indication of worn hoist
components. For this reason, the hoist’s chain guide, hook
block and liftwheel should be examined for wear and
replaced as necessary when replacing worn chain.

Also, these chains are specially heat treated and hardened
and should never be repaired.

A
load chain. Do not allow the chain to run dry. keep it clean
and lubricate at regular intervals with Lubriplate

®

Chain Oil 10-R (Fiske Bros, Refining Co.) or equal lubricant.
Normally, weekly lubrication and cleaning is satisfactory, but
under hot and dirty conditions, it may be necessary to clean
the chain at least once a day and lubricate it several times
between cleanings.

Used motor oils contain known carcinogenic materials.

Never use used motor oils as a chain lubricant. Only use

TO AVOID HEALTH PROBLEMS:

Lubriplate®Bar and Chain Oil 10-R as a lubricant for the
load chain.

When lubricating the chain, apply sufficient lubricant to
obtain natural run-off and full coverage, especially in the
interlink area.

LUBRICATION

Refer to Exploded View and Parts List on pages 10 thru 14.

The lubricants used in and recommended for the ShopAir
Hoist may contain hazardous materials that mandate
specific handling and disposal procedures.

TO 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.

If

the gears are removed from the housing, wipe the excess

ease off the outside surfaces of the Protector™ with a soft

gr
cloth and degrease the remaining gears and housings. Upon
reassembly, add 2 oz. of the above grease to gears and
housing. Also, coat the spline on the end of the first pinion
and shaft (620-131) with a Molydisulphide lubricant such as
Moly-Duolube 67 (Hercules Packing Co.).

Bearings

Needle bearings (620-109, 620-114, 620-115, 620-128 and
620-164) are packed at assembly with grease and should
not need to be relubricated. However, if the housings (620­113 and 620-107), liftwheel (620-127) or sheave wheel (620-

162) have been degreased, these bearings should be
greased using “Century Lubricants HB-11, #3” grease.

Seals

When reassembling the unit, wipe the inside surface of the
seals with “Century Lubricants HB-11, #3” grease.

Service Air Line Lubricator

The air line filter and lubricator is the only source of lubrication
for control valves and air motor. Fill lubricator with a good
grade air hoist motor oil or low machine oil (viscosity of 180
SSU at 100

0

F.). Multi-viscosity, detergent type oil is not
recommended. Feed one drop of oil for every 50 to 75 cubic
feet of air going through the air motor.

Hook Block

If the hook blocks are disassembled for inspection purposes,
wipe the grease from the hook knob and the hook knob
cavities in the hook blocks. At reassembly, coat the underside
of the hook knob and the knob bearing surfaces of cavities in
the hook blocks with Molykote BR-2-S (Dow Corning Corp.)
grease or equivalent.

Chain Guide, Liftwheel and Sheave Wheel

When the hoist is disassembled for inspection and/or repair, the
chain guide, stripper, sheave wheel (on double chain unit) and
liftwheel must be lubricated with Lubriplate

®

Bar and Chain Oil
10-R (Fiske Bros. Refining Co.) prior to reassembly. The
lubricant must be applied in sufficient quantity to obtain natural
runoff and full coverage of these parts.

LLooaadd CChhaaiinn

See above for lubrication of the load chain.

Exterior Finish

he exterior surface of the hoist has a durable, scratch

T
resistant baked powder coating. Normally, the exterior
surfaces can be cleaned by wiping with a cloth.

BRAKE

The brake is non-adjustable with a nominal 0.004 inch (0.012
mm) air gap and the brake disc must be replaced when the
gap reaches 0.012 inches (0.305 mm). The brake spacer
should be no more than 0.012 inches (0.305 mm) thicker than
the combined thickness of the brake disc and armature plate.

Failure to follow proper lockout/tagout procedures may
present the danger of injury from the escape of high
pressure air.

TO AVOID HEALTH INJURY:

Disconnect the hoist from the air supply and
lockout/tagout the main air supply valve before removing
the cover or servicing this hoist.

521), o-ring (620-536), coupling (620-523) and seal (620-535)
by removing screw (620-575). Removing the air cyclinder
assembly will expose the brake armature (620-118), brake
disc (620-117), brake spacer (620-193) and brake base plate
(620-116). Inspect these parts and replace if worn or
damaged. Check o-ring (620-536) and seal (620-535) and
replace these if worn or damaged. Make sure to install new
seal with the opening towards the coupling. Apply grease to
the outside of the lip seal and o-ring. Making sure that the
o-ring (620-536) is on piston shaft, slide the piston (620-521)
into the air cylinder (620-524). Install coupling (620-523) into
air cyclinder (620-524) using screw (620-575).

Assemble the brake base plate (620-116), brake spacer
(620-193), brake disc (620-117) and brake armature (620-

spacer (620-527) and end cover (620-533) to gear housing
(620-113) using the three screws (620-507).

Control Valve Assembly

Once a year, disassemble the control valve assembly (see
Exploded View, Pages 13 & 14) and check the condition of
the pistons, springs, spring seats, gasket, O-rings, valve
bolts, air fittings and muffler. Replace worn or damaged
parts. If the parts appear to be in good condition, do not
service other than lubricating them with light machine oil.

PROTECTOR

The Protector™ should operate for the normal life of the hoist
without service. The device has been lubricated and
calibrated and it should not be adjusted. If the Protector™ is
not operating properly (see testing on page 9), it must be
replaced with a properly calibrated unit from the factory.

PREVENTIVE MAINTENANCE

A preventive maintenance program should be established to
prolong the useful life of the hoist and maintain its reliability
and continued safe use. The program should include the
periodic and frequent inspections with particular attention
being paid to the lubrication of the various components using
the recommended lubricants (see page 11).

RECOMMENDED SPARE PARTS

To insure continued service of the ShopAir Hoist, the following

5. On the 250, 300 and 500# (Single Reeved) (113, 136
and 226 kg.) units, remove the hook block from the old
chain and attach it to the new chain by reusing the
chain pin (620-158).

On the 500, 600 and 1000# (226, 272 and 453 kg.)
units:

• Remove dead end plate (620-160) from hoist.

• Remove dead end pin (620-161) from the last link

of chain and pull chain out of dead end plate.

• Pull old chain out of hook block and disassemble

the hook block.

• Make sure the new chain is not twisted and wrap

the chain around the sheave wheel (620-162) with
welds down and towards the sheave wheel.

• Reassemble hook block and pull the new chain

through the hook block.

• Slide the dead end plate over the last link and

secure it using the dead end pin.

• Making sure the chain is not twisted between the

hook block and hoist, attach the dead end plate to
the stripper (620-143).

CUTTING CHAIN

Hoistaloy

®

load chain is hardened and it is difficult to cut.
The following methods are recommended when cutting a
length of new chain from stock or cutting off worn chain.
Always wear eye protection when cutting chain.

1. Use a grinder and nick

the link on both sides
(see right), then secure
the link in a vise and
break off with a
hammer.

2. Use a 7”(177 mm) minimum diameter by 1/8" (3.1 mm)

thick abrasive wheel (or type recommended by wheel
supplier) that will clear adjacent links.

3. Use a bolt cutter (see

right) with special cutter
jaws for cutting hardened
chain. Jaws should be 1
inch (25.4 mm) long.

TESTING

Before using, all altered, repaired or used hoists that have
not been operated for the previous 12 months must be
tested by the user for proper operation. First, test the unit
without a load and then with a light load of 50 pounds (23
kg) times the number of load supporting parts of load
chain to be sure that the hoist operates properly and that
the brake holds the load when control 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 a written report
prepared for record purposes. After this test, check the
Protector™ functions. If the Protector™ permits lifting a
load in excess of 200% of rated load, it should be
replaced.

*If the Protector™ prevents lifting of a load of 125% of
rated capacity, reduce load to rated capacity.

ORDERING INSTRUCTIONS

The following information must accompany all
correspondence and orders for replacement parts:

1. Hoist rated load from identification plate.

2. Serial number of the hoist from identification plate.

3. Length of lift.

4. Key number of part from parts list.

5. Number of parts required.

6. Part name from parts list.

7. Part number from the parts list.

NOTE: When ordering replacement parts, it is recom­mended that consideration be given to the need for
also ordering such items as gaskets, fasteners, seals,
etc. These items may be damaged or lost during
disassembly or just unfit for future use because of
deterioration from age or service.

Cutting chain can produce flying particles.

• Wear eye protection.

TO AVOID HEALTH PROBLEMS:

• Place a shield over chain to prevent flying objects.

Using “commercial” or other manufacturer’s parts to repair the
ShopAir Hoist may cause load loss.

TO AVOID INJURY:

Use only factory supplied replacement parts. Parts may look alike
but factory original parts are made of specific materials or
processed to achieve specific properties.
