DRUM 4 PAWL
Drum 4 (boom hoist) has a drum pawl which, when engaged,
prevents the drum from turning in the down direction.
The pawl is controlled by Drum 4 park switch in the
operator’s cab:
• When Drum 4 Park is turned ON, the pawl engages.
Hydraulic cylinder (3, View A) extends and spring force
(6) rotates pawl (2) into engagement with ratchet (1).
• When Drum 4 Park is turned OFF, the pawl disengages.
Hydraulic cylinder (3, View B) retracts and cam (5)
rotates pawl (2) out of engagement with ratchet (1).
NOTE: It may be necessary to boom up slightly to fully
disengage pawl (2) from ratchet (1).
Maintenance
The only maintenance required is to visually check the pawl
for proper operation. This should be done daily when the
boom hoist is in use.
If necessary, adjust eye bolt (4) so spring (6) has sufficient
tension to fully engage pawl (2) with ratchet (1).
In some cases, pawl (1) may come to rest on the top of a
ratchet tooth. There must be enough spring tension to pull
the pawl into the root of a ratchet tooth if the drum starts to
turn in down direction.
