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.
