3) Brake - Inspect for proper operation, ensur-
ing the brake does not slip while holding a load.
The hoist shall be capable of lifting 125% of the
rated load without any movement when the hand
chain is released. Check all surfaces for oil,
wear, deformation, cracks or foreign objects. If
any defects are noticed, disassemble and repair
or replace parts as needed (see page 17).
4) Chain Sheaves - Inspect for damage or
excessive wear that may affect hoist operation.
5) Hooks- Inspect both hooks for the following
conditions:
a) The hooks should rotate freely even
when under load.
b) Latches should be appropriately secured
in place and open/close properly.
c) Any signs of cracking (use of magnetic
particle or dye penetrants are
recommended).
d) Any indications of deformation including:
i)
Throat Width
(1) New style hooks (see Figure 12,
page 16) have elongation marks
that are measured by comparing
the distances between pins 1 and 2
and pins 1 and 3. The difference
between these distances should be
no more than 5 mm as shown in
Figure 4.
ii)
Twisting
- Check for twisting of the hook
(Figure 5). Discard if twisted over 10°.
