• Check that the name plate/label showing the hoist capacity is attached and clearly legible.
• Check lubrication and lubricate if necessary.
• Check the functioning of the chain drive in unloaded condition. When facing the hand chain
side of the hoist with no load, the brake is operating normally if the pawl "clicks" when the hand
chain is wound in a clockwise direction and does not "click" when operated in the anti-clockwi-
se direction.
• Check for loose or missing nuts and for missing split pins.
Check the brake function
Before starting work, always check operation of the brake. To do this, lift, pull or tension, then
lower or release a load over a short distance with the unit. When the hand chain is released, the
load must be held in any position. Repeat this at least twice before starting further work.
Inspect the supporting structure and attachment point
The attachment point for the hoist must be selected so that the supporting structure to which
it is to be fitted has sufficient stability and to ensure that the expected forces can be safely
absorbed. The unit must align freely also under load in order to avoid impermissible additional
loading. Check that the hoist and the load are correctly attached.
Inspect the hand chain
If the unit's hand chain has been supplied with a Hand Chain Joiner link, make sure that it
has been fitted correctly and is in good working order. See Chapter CHAIN AND HOOKS for
more information.
Inspect the load chain
Inspect the load chain for sufficient lubrication, mechanical damage and check for external
defects, deformations, superficial cracks, wear, excessive rust and corrosion marks. Check for
gouged, twisted and distorted links, and for deposits of foreign material which may be carried
into the chain block mechanism. Do not operate chain blocks with twisted, kinked or damaged
chain links. See Chapter CHAIN AND HOOKS.
Inspection of the Load Chain Anchoring
The load chain anchoring must always be fitted securely at both ends. There must be no
wear or incorrect alignment.
Inspection of the top hook and bottom load hook
The top and load hooks must be checked for cracks, deformations, damage, wear and
corrosion marks. The safety latch must be attached, move freely and be fully functioning.
Hooks that are bent, worn or have openings which are enlarged beyond normal throat opening
(Chapter TECHNICAL DATA/HOOKS) should not be used. If the latch does not engage in
the throat opening of the hook, the chain block should be taken out of service. Hooks that do
not fulfil all requirements must be replaced immediately. See Chapter CHAIN AND HOOKS
and Chapter TECHNICAL DATA/HOOKS for more information. Welding on hooks, e.g. to
compensate for wear or damage is not permissible.
Inspection of chain reeving in the bottom block
All units with two or more chain falls must be inspected before initial operation to ensure that
the load chain is not twisted or kinked. The chains of hoists with two or more falls may become
twisted if the bottom block is rolled over "capsized" (i.e. bottom hook has looped through the
multi fall chain). A twist in the load chain can damage the chain block and cause injury.
