GENERAL SAFETY RULES
WARNING!
READ AND UNDERSTAND ALL INSTRUCTIONS
Failure to follow all instructions listed below may result
in serious personal injury to the operator or nearby personnel by nature of released load or broken hoist components.
SAVE THESE INSTRUCTIONS
The following are guidelines for the safe operation of overhead hoists. A few minutes spent reading these rules can make an operator aware of
dangerous practices to avoid and precautions to take for personal safety and the safety of others. Frequent examinations and periodic inspections
of the equipment as well as the use of "common sense" and observance of safety rules may save lives, time and money.
HOIST SELECTION
1. Choose a hoist with the capacity for the job. Know the capaci-
ties of your hoists and the weight of your loads, then match them.
2. The application, size and type of load, attachments and period
of use must be taken into consideration when selecting the right
hoist for the job.
HOIST INSPECTION
3. Do not operate a damaged or malfunctioning hoist. Do not
operate a hoist with a twisted, kinked or damaged chain.
4. Make sure the hoist suspension hook is securely attached
to a support that has sufficient strength to hold several
times the rated load of the hoist.
5. All hoists should be visually inspected before use in addition to regular, periodic maintenance inspections. Inspect
hoists regularly and insure that operational warning labels and tubes
are legible. Replace damaged or worn parts and keep appropriate
records of maintenance.
6. Make sure that load slings (or other approved single attach-
ments) are properly sized and seated in the hook saddle.
7. Make sure that the hook latch, if used, is closed and not
supporting any part of the load.
8. Replace damaged or malfunctioning hook latches.
9. Check hoist for gouged, twisted or distorted chain links.
10. Chains should be checked for deposits of foreign material
which may be carried into the hoist mechanism.
11. Deficiencies should be noted and brought to the attention
of a supervisor. Be sure defective hoists are tagged and
taken out of service until repairs are made. Under no circumstances should you operate a malfunctioning hoist.
HOIST USE
20. Take up slack chain carefully, check load balance, lift a few
inches (centimeters) and check load holding action before
continuing.
21. Avoid swinging of load or load hook.
22. Use hook latches wherever possible.
23. Hooks that are bent, worn or have openings that are en-
larged beyond normal should not be used. If latch does not
engage throat opening of hook, hoist should be taken out of
service.
24. Check brake for evidence of slippage under load.
25. Do not lift more than the rated load.
26. Be sure hoist is solidly held in the uppermost part of the
support hook arc.
27. Do not lift at an angle. Be sure hoist and load are in a straight
line.
28. Be sure load is hooked securely. Do not tip load the hook.
Do not load hook latch. Hook latch is to prevent detachment
of load under slack chain conditions only.
29. Do not lift a load unless chain is properly seated in chain
wheel.
30. Do not use load chain as a sling or wrap chain around the
load.
31. Do not lift a load if any binding prevents equal loading on all
supporting chains.
32. Do not operate hoist with other than manual power.
33. Do not allow your attention to be diverted from operating
the hoist.
34. Do not operate hoist beyond limits of load chain travel.
35. Do not leave a suspended load unattended unless appropri-
ate precautions have been taken.
36. Do not allow sharp contact between two hoists or between
hoist and obstructions.
12. Hoists were designed to ease our burden, carelessness not
only endangers the operator, but in many cases, a valuable
load.
13. Become familiar with hoist operating controls, procedures
and warnings.
14. Maintain firm footing or be otherwise secured when operating hoist.
15. Do not operate with hoist head resting against any object. Lift
the load gently. Do not jerk it.
16. Do not lift people or loads over people.
17. Make sure everyone is clear of the load when you lift.
18. Do not remove or obscure operational warning notices.
19. Make sure that the load is free to move and will clear all ob-
structions.

37. Protect load chain from weld spatter or other damaging
contaminates.
38. Do not allow the chain or hook to be used as a ground for
welding.
39. Do not allow the chain or hook to be touched by a live welding electrode.
40. Hoists should be kept clean and free of dust, dirt, moisture,
etc. which will in any way affect the operation or safety of
the equipment.
41. Chain should be lubricated as recommended in this
operator's manual.
42. Carefully test hoist after repairs before returning it to full
service (See "Testing" under the "Maintenance" section).

OPERATION
WARNING!
To reduce the risk of injury, carefully check unit for
external damage prior to installation. Do not operate a damaged or malfunctioning hoist. Do not
operate a hoist with a twisted, kinked or damaged
chain. Operating a unit with obvious external damage may cause load to drop resulting in personal
injury and/or property damage.
After mounting and before placing in service, check the hoist for proper
operation. Before operating the 3 and 5 ton units, make sure that all strands
of chain are straight and have no twists (due to capsized hook). If the
chain is twisted, reverse capsize. To operate the hoist, pull on the hand
chain as indicated below (Fig. 1).

Recommended Procedures
1. The hoist must always be rigged to lift in a straight line from hook to
hook.
a. Rigging can be defined as the process of lifting and moving
heavy loads using hoists and other mechanical equipment.
Skill acquired through specialized experience and study is
essential to safe rigging operations. For rigging information,
we recommend consulting a standard text book on the subject.
b. The hoist must always be free to swivel on the upper hook.
Under no condition should the hoist frame be allowed to bear
on any support when in use as this would cause bending of
the hook or frame and damage the unit.
2. When preparing to lift or move a load, be sure that the attachments
to both hooks are firmly seated in the saddles of the hooks. Avoid off
center loading of any kind, especially loading on the tip of the hook.
Observe that the chain hangs straight (without twist) from hoist to
lower hook.
3. When lifting, raise the load only enough to clear the floor or the
support, and check to be sure brake will hold load and that attachments to the load are firmly seated. Continue the lift only after you
are assured the load is free of all obstructions.
4. Do not load beyond the rated capacity of the hoist. Rated capacity
can be achieved with the hand chain pulls listed (Fig. 2)
Fig. 2
Hand Chain Pull
Hoist Rated Load
Tons (Kg)
to lift Rated Load
Pounds (Kg)
Test the operation of the hoist before operating at rated capacity.
Operate the hoist with no load and then with a light load of approximately
50 pounds (23 Kg) times the number of load supporting chains to make
sure it operates properly and that the brake holds the load when the
hand chain is released.
WARNING!
To reduce the risk of injury, stop operating in the
lifting direction before the hook block contacts the
hoist frame and/or hanger, as noted by sudden
increase in hand chain pull or tipping of the hook
block. Operating the 3 and 5 ton hoists in the lifting
direction with the hook block in contact with the
frame and/or hoist hanger may break the chain and
allow the load to drop.
WARNING!
To reduce the risk of injury, do not lift people or loads
over people.
Do not lift more than the rated load.
Do not lift at an angle.
Do not use load chain as a sling.

NOTE: Since the 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

hoist.
WARNING!
To reduce the risk of injury, do not exceed the hand
chain pulls specified in Fig. 2. Exceeding the rated
capacity of the hoist may cause load to drop resulting in personal injury and/or property damage.
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 result in a twisted chain and a jammed liftwheel. The chain
could also be damaged at the hook.
6. Do not move a load over the heads of other personnel. Warn personnel
of your intention to move a load in their area. Stand clear of all loads.
7. Do not leave a suspended load 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. Do not operate hoist with other than manual power.
11. Do not use this or any other overhead materials handling equipment for
lifting people.
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.
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 reduced control.
WARNING!
To reduce the risk of injury, operate hoist using
manual power only. Power operation may result in
structural damage or premature wear that may cause
a part to break and allow the load to fall.
MAINTENANCE
WARNING!
To reduce the risk of injury, do not allow the load to
bear against the hook latch and/or hook tip. Apply
load to hook bowl or saddle only. Allowing the load
to bear against the hook latch and/or hook tip can
result in loss of load.
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 must be based upon the
type of service to which the hoist will be subjected. Conduct inspections
only when there is no load on hoist. If a trolley is used to suspend the
hoist, secure the trolley from movement. Place warning signs and barriers in area when overhead maintenance is taking place.
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 and should include the following items:
1. All functional operating mechanisms for maladjustment and unusual
sounds.
2. Hoist braking mechanisms for evidence of slippage.
3. Load chain for lubricant, wear, damaged links or foreign material.
4. Proper reeving of load chain (See “Reeving of Load Chain” under the
“Maintenance” section).
5. Hooks for damage, cracks, twists, latch engagement and latch operation.
Any deficiencies noted are to be corrected before the hoist is returned
to service.
Periodic Inspections
These are visual inspections by an appointed and qualified person or
service center 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 annually and for heavy service, inspections are to be performed semiannually.
Due to the construction of the hoist, it will be necessary to partially
disassemble the unit to perform the periodic inspections.
Two points of caution to be observed in disassembly are:
1. Loose rollers and bearing balls are used in various locations in the
unit. Care must be taken so as not to lose or misplace these since
they may drop from the unit as the various parts are disassembled.
The number of rollers or bearing balls used are listed in Fig. 3.

2. The latch is secured to the hook (upper and lower) by a rivet. To
remove the latch, it is necessary to remove the head of the rivet by
grinding or drilling. For replacement of the latch, refer to Step 4 of the
Assembly Instructions.
The periodic inspections are to include those items listed under frequent
inspections as well as the following:
1. Inspect chain and end connections for excessive wear or stretch.
2. Check for worn, cracked or distorted parts such as hook blocks,
hoist frame, hoist hanger, chain guide, liftwheel, sheave wheel,
handwheel, stripper, loose end pin, shafts, gears, pins, rollers, bearings, and hook block screw.
3. Inspect for wear on the tip of the pawl, teeth of the ratchet and
pockets of the liftwheel and handwheel.
4. Check for loose or missing bolts, nuts, pins or rivets.
5. Inspect brake components for worn, glazed or contaminated friction
discs, worn pawls, cams and scoring of the handwheel hub, ratchet
and friction hub. Replace friction discs if the thickness is less than
.044 in. (1.12 mm) on 1/2 and 1 ton units and .059 in. (1.5 mm) on 2,
3 and 5 ton units.
6. Check for corroded, stretched or broken pawl spring.
7. Check for free movement of the pawl on the pawl stud. Apply a thin
coat of lubricant to the pawl stud before reassembling the unit (see
lubrication section).
8. Check for damage to the hooks, hook retaining nuts, collars, pins,
welds or rivets used to secure the retaining members. Dye penetrant, magnetic particle or other suitable crack detecting inspections should be performed at least once a year.
9. Check for damage of supporting structure or trolley if used.
10. Check for warning labels required by ASME B30.16 par. 16-1.1.4,
except as provided in par. 16-2.3.3 (c) (8).
Any deficiencies noted are to be corrected before the hoist is returned
to service. 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.
page 5
Hook Inspection and Maintenance
Hooks damaged from chemicals, deformations or cracks, or that have
more than a 10 degree twist from the plane of the unbent hook, excessive opening or seat wear must be replaced.
Hooks that are opened and allow the latch to disengage the tip must be
replaced.
Any hook that is twisted or has excessive throat opening indicates
abuse or overloading of the unit. As a result, other components of the
hoist could be damaged.
The chart in Fig. 4 should be used to determine when the hook must be
replaced. To measure the throat opening, depress the latch against the
hook body as shown in Fig. 4.

Check to make sure that the latch is not damaged or bent and that it
operates properly with sufficient spring pressure. Spring pressure keeps
the latch tight against the tip of the hook and allows the latch to spring
back to the tip when released. If the latch does not operate properly, it
should be replaced.

NOTE: Worn chain can be an indication of worn hoist components. For
this reason, the hoist's chain guide roller and liftwheel should be examined for wear and replaced as necessary when replacing worn chain.
Load chains are specially heat treated and hardened and should never
be repaired.
Do not use replaced chain for other purposes such as lifting or pulling. Load chain may break suddenly without visual deformation. For this
reason, cut replaced chain into short lengths to prevent use after disposal.
Before returning chain to service or after replacing a load chain, lubricate liberally with Bar and Chain Oil such as Lubriplate® 10-R (Fiske
Bros. Refining Co.) or equivalent. Remove excess lubricant from chain
by wiping with a clean, dry cloth.
Hand Chain
Cleaning and Inspection
Hand chain should be cleaned, inspected and gaged in the same manner
as a load chain.
As received from the factory, the hand chain contains an unwelded link.
This link can be placed in a vise and twisted open to facilitate changing
chain length. The opening and closing of the connecting link more than
twice is not recommended. Connecting links must not be made by cutting
the weld side of a standard hand chain link.
Hand chain should be assembled to handwheel free from twists with weld
on vertical link facing inwards towards handwheel and weld on horizontal
link facing towards the handwheel side plate.
Care must be taken to assure that there is no twist in the hand chain loop.
Lubrication
WARNING!
To reduce the risk of injury, avoid contact with
lubricants. Handle and dispose of lubricants only as
directed in applicable Material Safety Data Sheets
and in accordance with applicable local, state and
federal regulations.
Load Chain
Cleaning and Inspection
Clean the load chain with a non-acid or non-caustic type solvent then
slack the chain and make a link-by-link inspection for nicks, gouges,
twisted links, excessive wear or stretching. Worn chain should be gaged
throughout it's entire length and replaced if beyond serviceable limits.
To determine if the load chain should remain in service, check gage
lengths as indicated in Fig. 5. A chain that is nicked, gouged, twisted or
worn beyond length indicated, should be replaced before returning hoist
to service. Chain should be clean, free of twists and pulled taut before
measuring. In cases where the wear is localized and not beyond serviceable limits, it is sometimes possible to reverse the load chain, end for
end, and allow a new section to take the wear. Proper installation of the
load chain is covered in the section on “Reeving Load Chain”.

Lubricate load chain with a light coat of Bar and Chain Oil such as
Lubriplate® 10-R (Fiske Bros. Refining Co.) or equivalent. Be sure the
lubricant reaches the bearing surfaces between the links. Remove excess oil from the chain by wiping with a clean, dry cloth.
WARNING!
To reduce the risk of injury, never use used
motor oil as a chain lubricant. Used motor oil
contains unknown carcinogenic materials. Use
only Bar and Chain Oil such as Lubriplate® 10-R or
equivalent as a lubricant for the load chain.
The hoist normally requires no lubrication, except for periodically lubricating the load chain or when the unit is disassembled for periodic
inspections, cleaning or repairs.
page 6
WARNING!
To reduce the risk of injury, do not use any grease or
lubricant on braking surfaces. The brake is designed
to operate dry. Using any grease or lubricant on the
braking surfaces will cause brake slippage and loss
of load control which may result in injury and/or
property damage.
The brake is designed to operate dry. Do not use any grease or lubricant
on the braking surfaces. When lubricating parts adjacent to the brake,
do not use an excessive amount of lubricant which could seep onto the
brake surfaces.
When the hoist is disassembled for periodic inspections, check the
pawl for free movement and apply a light coat of spray lubricant such
as WD-40 (WD-40 Co.) or equivalent, to the pawl stud. When the hoist is
disassembled for cleaning or repairs, the following locations should be
lubricated using approximately 1 oz. (29.5ml) per hoist of Extreme Pressure Grease such as Molykote BR-2-S (Dow Corning Corp.) or equivalent:
Threads of handwheel, gears, liftwheel rollers, gear bearing rollers, journals of chain guide and dead end pin, sheave wheel rollers
(3 and 5 ton), hook bearing balls (3 and 5 ton), hook collar journals
(3 and 5 ton) and dead end stud (3 and 5 ton).
NOTE: To assure extra long life and top performance, be sure to lubricate the various parts of the hoist using the lubricants specified.
Assembly
Particular attention must be given to the following when assembling the
hoist:
1. Assemble the brake components as shown in Fig. 6. The ratchet teeth
must face as shown and engage the pawl. Do not lubricate the brake
surfaces. The brake operates dry. Assemble handwheel to pinion shaft
and turn handwheel to seat brake components. Assemble the pinion
shaft nut to the shaft until the nut bottoms. Then back nut off at least
one but not more than two flats. Insert cotter pin and bend ends to
secure same.

3. For proper operation, the correct number of rollers must be installed
at the rotating points of the liftwheel, intermediate gears and hook
block sheave (3 and 5 ton). The correct number of bearing balls
must be installed in the hook collar to retain the hook and insure
proper loading. Refer to Fig. 3 for the correct number of bearing
balls/rollers at these locations. Applying an Extreme Pressure grease
such as Molykote BR-2-S (Dow Corning Corp.) or equivalent to the
rollers or bearing balls will help hold them in position during assembly.
4. When assembling the latch to the hook, the end of the rivet must be
peened over. When peening over the rivet, apply only enough force
to form the head and retain the rivet. Excessive force will deform the
latch and make the latch inoperable.

1. Attach approximately 20" (508 mm) of soft wire to the loose end of
the chain. Pass the wire over the top of the liftwheel and down
between the liftwheel and the chain guide.
2. Position the chain so that the first, as well as the third link stands on
edge with the weld away from the liftwheel and the second link lays
flat on the liftwheel.
3. After the chain has been started, pull hand chain in the hoisting
direction until about 2 feet (0.6 M) of chain has passed over the
liftwheel. The wire should now be removed from the chain.
4. Remove the cotter pin from the loose end pin and slide the loose end
pin to the side into the gear housing, leaving approximately 1/2"
(12.7 mm) of the pin protruding from the geared side plate.
5. Loop the chain making sure there are no twists up to the loose end
pin and slide the pin through the last link of the chain. Slide the loose
end pin into the hole in the handwheel side plate until the cotter pin
hole is visible.
6. Secure the loose end pin by reinstalling the cotter pin and spreading
the legs of the cotter pin.
WARNING!
To reduce the risk of injury, feed load chain
between liftwheel and chain guide before attaching it to the loose end pin. Failure to properly
install the load chain may cause the chain to lift
out of the liftwheel pockets and allow the load to
drop.

3 and 5 Ton Hand Chain Hoists
The load chain must have an odd number of links. After attaching the
chain to the loose end pin, operate in the hoisting direction until the load
end of the chain is approximately 5 feet (1.5M) long. Run the chain
through the hook block (first link around the sheave must stand on edge)
and up to the dead end block. Secure chain to dead end block using the
stud, nut and cotter pin. Refer to Fig. 9.

WARNING!
To reduce the risk of injury, check each stage of
reeving the chain to be sure it has no twists. On the
3 and 5 ton units, twisted load chain will cause the
chain to jam in the liftwheel or sheave wheels and
this may break the chain and allow the load to
drop.

cover of this operator’s manual.

Testing
Before use, all altered, repaired or used hoists that have not been operated for the previous 12 months should be tested by the user for proper
operation. Test the unit without a load and then with a load of 50 pounds
(23Kg) times the number of load supporting chains, to be sure that the
hoist operates properly and that the brake holds the load when the hand
chain is released. Then test with a load of 125% of rated capacity. Hoists
in which load sustaining parts have been replaced should be tested with
a load of 125% of rated capacity by, or under the direction of, an appointed person and a written report prepared for record purposes.

If your hoist is damaged, call 1-800-414-6527 for assistance.
