7.1.13.2 Hook operated control limit switch, Frame size: VT1, VT2, VT3, VT4.
The hook operated limit switch trips hoisting movement when the hook reaches the adjustable lever. The hook
operated limit switch can be reset automatically or manually. With automatic reset, the hoisting movement is
possible again after tripping as soon as the hook has been lowered from the switching area. The hook operated
limit switch with automatic reset can be used as a working limit before the tripping height of the standard upper
limit.
With manual reset, the hoisting movement is not possible before the limit switch has been manually reactivated. A
hook operated limit switch with manual reset can be used as a backup switch for the standard upper limit switch.
When a manual reset limit switch is used as a backup switch and this switch stops the hoisting movement, the
function of the rotating limit switch has to be checked and corrected before using the hoist again.
The hook operated control limit switch increases the hook approach (the hook-rail distance).
