DESCRIPTION
Front Axle
The front axle Figure 8-1 is a rigid-mounted drive axle,
attached to the frame of the crane by eight bolts, washers
and nuts. The axle includes a 3 piece spiral bevel input, two
reduction drive hubs and inboard brakes.
Rear Axle
The crane may be equipped with either a rear drive axle or
rear non-drive axle. Figure 8-2 shows only the drive axle.
The axle is pin mounted to the frame of the crane, allowing it
to pivot in both directions. The axle will pivot 1-1/2° in both
directions. The drive axle includes spiral bevel input, two
reduction drive hubs and brakes in the drive hubs. The non-
drive axle does not have a 3 piece spiral input.
