THIRD WRAP INDICATOR (OPTIONAL—
STANDARD ON CE)
Description
The third wrap indicator (Figure 5-9) is installed to give the
operator an indication that the wire rope is down to the last
three wraps on the hoist drum and no more rope should be
reeled out. In addition to the warning light in the cab
illuminating when down to the third wrap, a lockout valve is
actuated to stop hoist down operation.
Maintenance
The third wrap indicator switch mechanism must be adjusted
such that only when the hoist has three wraps of cable
remaining on the drum, the switch is actuated. Once
adjusted properly, ensure there is no continuity through the
switch when actuated and continuity through the switch
when not actuated.
