Tiger TCB Series Original Instruction Manual page 11

The following checks should be carried out before starting work:
Check the unit

Inspect the unit for visual defects, e.g. deformations, damage, cracks, wear and corrosion marks.
 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-clockwise 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. This check is intended to
ensure that even at temperatures below 0 °C, the brake discs are not frozen. Repeat this at least twice before starting further
work. Stop the load at various positions to test holding power and observe the amount of drift, if any.
To adjust the brake: (See Figure 1)
A. Fully-tightened the check nut (C-31).
B. Slacken off slightly from Position A, and insert the cotter/split pin (C-32) in the check
nut.
Note: Replace the brake disc if thickness is less than 1.5mm (0.06 inch). If the brake
discs are bonded with the ratchet gear, the entire bonded unit will need to be replaced.
! WARNING
If the brake does not function properly, the unit must be immediately removed from service and placed in a quarantine
area until it can be repaired by a relevant competent person.
Inspect the supporting structure and attachment point
Inspect the supporting structure for visual defects, e.g. deformations, damage, cracks, wear and corrosion marks.
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. The selection and calculation
of the appropriate supporting structure are the responsibility of the operating company.
Inspect the hand chain
If the unit's hand chain has been supplied with a Tiger Hand Chain Joiner link, make sure that it has been fitted correctly and
is in good working order. See Chapter 6 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 6 Chain and Hooks.
