Danger to life due to deformed fork hooks!
Always observe the following:
– Ensure that the hooks of the fork arm do not bend upwards by more than
0.079 inches (2 mm).
Fork hooks are used for both power transmission and as the locking device. If
the fork hooks are deformed due to material fatigue or overloading, the specified
nominal load capacity of the fork arms is no longer ensured. This could (e.g.,
due to breakage) cause the load to fall and result in serious accidents.
