MINIMUM BAIL LIMIT
See Figure 5-5 for following instructions.
The optional minimum bail limit assembly on Drum 1 and 2
(front and rear) is a protective device which limits how much
wire rope can be spooled off each drum.
The minimum bail limit stops the corresponding drum when
there are 3 to 4 wraps of wire rope remaining on the first
layer (View A).
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.
Weekly Maintenance
1. Check minimum bail limit switch for proper operation.
Pay out wire rope from drum (4). Drum should stop with
approximately 3 to 4 wraps of wire rope remaining on
first layer. Adjust limit switch (6) if necessary.

shaft are tight.
3. Check that return spring (11) has sufficient tension to
