BAIL LIMIT ADJUSTMENT
NOTE:
Reference to LED is past production.
The optional minimum bail limit assembly on Drum 1 (main
hoist in insert), Drum 2 (main hoist in boom butt), and Drum 3
(whip hoist on crane) is a protective device which limits how
much wire rope can be spooled off the corresponding drum.

corresponding drum when there are 3 to 4 wraps of wire rope
remaining on the first layer. The drum can be operated in the
hoist direction when the minimum bail limit switch is
contacted.
Adjusting the minimum bail limit switch requires operating
the drum to spool wire rope off the drum.
