G
Risk of accidents due to incorrect setting or intended triggering
Prior to operating the crane, ensure that the lowering limit switch is set
correctly and always complete the lowering operation before the lowering
limit switch is triggered.
This prevents the hoist rope becoming damaged due to complete unreeling
or switching off at high speeds, and the load being dropped as a result.
G
Risk of accidents due to adjustments made to the lowering limit switch
Always re-adjust the lowering limit switch if you unreel hoist rope from the
stationary rope drum. The lowering limit switch does not record the
number of these winds.
This prevents the lowering limit switch switching off too late or not switch-
ing off at all, the hoist rope being damaged and the load being dropped.
