Weekly Maintenance
Perform the following during weekly maintenance:
1. Check the minimum bail limit switch for proper
operation:
a. The limit switch should be depressed to the
dimension given in Figure 5-3
for normal operation.
b. Pay out wire rope from the drum. The drum should
stop with approximately 3 to 4 wraps of wire rope
remaining on the first layer. Adjust the limit switch if
necessary.
2. Make sure the cap screws holding the rollers on the
lever shaft are tight.
3. Check the tension on the return springs. If necessary,
adjust the eyebolts so the springs hold the rollers snug
against the bare drum.
Adjustment
Use the following steps during adjustment:
1. Pay out wire rope until the rollers are against the bare
drum with 3 to 4 wraps of wire rope remaining on the first
layer.
2. Make sure the rollers (2) contact the drum (4).
3. Turn the adjusting screw (6) until the limit switch is
depressed to 43,4 mm (1.71 in) as shown in Figure 5-3
.
4. Spool several wraps of wire rope onto the drum. Then,
pay out wire rope. The drum must stop with 3 to 4 wraps
of wire rope remaining on the first layer.
Repeat the adjustment steps if necessary.
5. Tighten the jam nut against the mounting plate to lock
the adjustment.
6. Make sure the return springs have sufficient tension to
hold the rollers snugly against the bare drum. Adjust the
eyebolts if necessary.
