Hooks Replacement for Model 555
INSPECT
WARNING
The lifting hooks are safety critical compo-
nents due to the fact that it is the hook that
carries all the load when picking up and carry-
ing a container. Hooks are a wearing part and
should be inspected for wear and or damage
on a regular basis.
1.
Check hook for cracks. Replace hook if damaged.
2.
Check inside angle of hook.
New hooks have
22 mm (0.87 in.) of material between flat por-
tion of hook and top of hook. The hook should
be replaced if worn area leaves less than 15 mm
(0.59 in.) from start of wear area to flat portion
of hook. See Figure 9 and Figure 10.
3.
Check wear area of hook where corner casting
of container is carried. This area should be in-
spected and when wear is more than 5% of origi-
nal thickness, hook should be replaced. See Fig-
ure 9 and Figure 10.
4.
Check tightness between nuts and threads of
hook. Hook should be replaced if threads of hook
become worn. See Figure 9.
5.
The pin that hook is secured through can wear
and should be replaced if excess play is discov-
ered.
WARNING
Do not try to correct hook alignment by bend-
ing. Replace damaged hooks.
6.
A common fault that can be found is hooks get
bent sideways. If hook is bent more than 5 de-
grees, it should be replaced with a straight one.
