"Hoist limit” warning light (A2B)
This red warning light lights up when the hoist limit switch
contacts open, i.e. when a hoist limit situation has occurred.
The acoustic alarm sounds and load-moment-increasing
crane movements are switched off at the same time.
A hoist limit situation occurs when the hook block
comes into contact with the boom head. The danger
exists in such situations that the hoist rope will
break, causing the load to fall. A hoist limit situation
could arise from the load being pulled against the
boom head or from the boom being extended or
lowered without the hoist rope being spooled off the
winch.

“Hoist limit switch bypass” warning light

of the hoist limit switch has been manually bypassed.
