2250 SERVICE/MAINTENANCE MANUAL HOISTS
SECTION 5
HOISTS
ADJUSTING THE MINIMUM BAIL LIMIT
General
The minimum bail limit assembly is a protective device. It
automatically stops the corresponding load drum from
lowering when there are three to four wraps of wire rope
remaining on the drum.
The load drum can be operated in the HOIST direction when
the corresponding minimum bail limit is contacted.
Weekly Maintenance
See Figure 5-1 for the following procedure.
1. Check for proper operation of each minimum bail limit
assembly, as follows.
a. Land the load.
b. Pay out the wire rope from the load drum.
c. The load drum must stop when there are three to
four wraps of wire rope remaining on the drum.
2. Verify that the capscrews (3) holding the rollers (2) on
the bail limit lever (1) are tight.
3. Check the tension of the return spring (9). If necessary,
adjust the eyebolt (10) so the spring holds the rollers
snugly against the drum (4).
WARNING
Falling Load Hazard!
If the proper precautions are not followed, the wire rope
can be pulled out of the drum, and the load will drop,
which could result in death or serious injury.
Do not operate either load drum with less than three full
wraps of wire rope on the drum.
