HEALTH & SAFETY INFORMATION
GENERAL SAFETY INSTRUCTIONS
WARNING: - Before the use of this or any other lifting equipment all persons who
install, operate or maintain this equipment should read and fully understand this
manual. If chain blocks or any other lifting equipment presents the possibility of
personal injury or damage to property, then it should not be used.
- Ensure that the chain block is fully inspected before every use.
- Chain blocks are only to be operated by a trained operator.
- Do not exceed the maximum lifting capability of the chain block.
- Ensure that the fixing point is substantial enough to take the load which is intended
to be lifted.
- Ensure the chain block can swivel freely on this upper hook.
- Never allow the chain block housing to bear any support when lifting a load.
- Ensure the suspension hooks fits and sits freely within the support clamp.
- Ensure the chains are not twisted or obstructed to prevent free running of the chain.
- Never use undue effort to force the chain hoist to operate.
- Never allow oil or grease to come in contact with the brake.
- Never use the load chain as a sling.
- Never wrap the chain around the load which is to be lifted.
- Never leave the load suspended in the air unattended.
- Do not lower the hook to a point where the chain becomes taut between the lift
wheel and the loose end pin.
- THE CHAIN BLOCK:
- Ensure the chain block is positioned directly over the load which is to be lifted, this
will prevent side lifting.
- While the load is lifted ensure no persons are under the load.

- Never use a chain block or any other overhead lifting equipment for lifting persons.
- Never use a chain block in wet, explosive or corrosive enviroments.

HEALTH & SAFETY INFORMATION
Always ensure that the product is fully inspected before every use, this will prevent damage
or serious injury to person.
FREQUENT INSPECTION
A visual inspection is to be carried out by a trained person before every use. This
inspection should consist of:
- Evidence of slippage on the braking mechanisms.
- Inspection of the load chain for wear, lubricant, damaged chain links or dirt.
- Hooks for damage, fracture marks, cracks, latch engagement and latch operation.
- Any missing parts or safety devices
- Housing is not distorted.
PERIODIC INSPECTION
An appointed person who over see the visual inspection and ensure that records are
taken to ensure continue evaluation.
It will be necessary to partially disassemble the unit to perform more periodic
inspection.
The periodic inspection are to include the following -
- more in depth inspection to look for wear, cracks or distortion of all parts of the
chain block including - hooks, chains, chain guide, hook collar, dead end stud, all
nuts, bolts and pins, shafts, gears and bearings.
- Inspection of the chain for excessive wear or stretch, (see maintenance section for
further details on Gaging Load Chain Wear).
- Inspection for wear on the tip or the pawl, teeth or the ratchet and pockets of the lift
wheel and hand wheel, hook block sheaves and hanger sheaves
- Loose or missing bolts, nuts, pins or rivets.
- Inspection for corroded, stretched or broken pawl spring.
- Inspection of the brake compartment for worn, glazed, or oil-contaminated friction
discs and scoring of the hand wheel hub, ratchet and friction hub.
Any deficiencies noted are to be corrected before the hoist is returned to service.
Any parts that are deemed unserviceable are to be replaced with new parts before the
unit is returned to service.
OPERATION AND USE
WARNING:
Before each use ensure that the lever hoist is fully inspected.
Ensure that all chains are not twisted. The chain block must always be rigged to lift in
a straight line. The chain block must always be free to swivel on the upper hook and
not be disrupted in any way. Under no condition should the block frame or hanger
bear any support or weight of the load.

NOTE: The ambient operating temperature of this chain block
is between –10°C and +50°C.
MOUNTING THE CHAIN HOIST (Fig.1.):
Ensure that the hook sits over the holding beam of a
secure beam clamp or dolly. The secure latch should be
in the closed position once the unit is hung. Before
attaching the load, ensure the hand chain runs freely.
LIFTING THE LOAD:
Ensure that the lower hook is attached to the load
securely over the centre of it's gravity, this will prevent
the load from tilting or twisting while the lift happens.
Ensure that the surrounding area is free of obstacles.
To lift the load, move the chains through your hands in
a clockwise direction at an even rate. Sudden jerks can
cause the load to twist and tilt. To lower the load, run
the chain in an anti-clockwise direction, ensure that the
area below the load is free of obstacles.
Be aware that the braking mechanism can become
heated during prolonged lowering of loads. FIG.1
MAINTENANCE
Care should be taken when handling and disposing of the lubricants. Clean the chain
with a non-acid and non-caustic type solvent.
HOOK INSPECTION:
Hooks damaged from chemicals, deformations or crack, or that have more than a 10
degree twist from the plane of the unbent hook or excessive opening or seat wear
must be replaced.
Hooks that are opened and those allow the latch to disengage the tip, must be
replaced.
Any hooks that is twisted or has excessive throat opening indicates abuse or
over-loading of the unit. Other load sustaining components of the hoist should be
inspected for damage.
CHECK TO ENSURE THAT THE LATCH IS NOT
DAMAGED OR BENT (FIG.2.):
If the opening has been increased due to use,
measure the throat opening, depress the latch
against the hook body as shown, once the
measurement has been taken compare against the
chart below.

Hoist Capacity
Replace hook when the opening is greater than
1000kgs
28.6mm
2000kgs
38.5mm
GAUGING LOAD CHAIN WEAR (Fig.3.):
To determine if the load chain should continue to
Be used. Check the gauge lengths as shown. Chain
wornbeyond length indicated, severely nicked,
gouged or twisted should be replaced before using
the chain block again. Both chains should be cleaned,
free of twists and pulled taut before measuring. In
cases where the wear is localized and not beyond
serviceable limits, the chain should be replaced.
HAND CHAIN:
The hand chain should be cleaned, inspected and gauged in the same manner as the load
chain. The hand chain does contain an un-welded link. Therefore, if it is necessary to
shorten the hand chain or replace the hand chain, a hand chain connecting link will be
required. Note, opening and closing the connecting link more than twice is not
recommended. Also, connecting links must not be made by cutting the weld side of a
standard hand chain link. Care must be taken to ensure that there is no twists in the hand
chain loop.
LUBRICATION:
Lubricate the load chain with a light coating of chain oil. Be sure the lubricant reaches the
bearing surfaces between the links, remove the excess oil from the chain using a cloth.
WARNING:
The brake is designed to operate dry. Do not use any grease or lubricant on the braking
surfaces. When lubricating pans adjacent to the brake, do not use excessive amount of
lubricant, which could seep onto the brake surfaces.
