"Hoist limit" warning light
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 ex-
tended or lowered without the hoist rope being spooled off
the drum(s).
