SWING GEARBOX AND BRAKE
Description
The swing gearbox and brake (see Figure 6-1), used in
conjunction with the swing motor, rotates and stops the
superstructure. A pedal on the cab floor is used to activate
the swing brake. The swing gearbox is bolted to the
superstructure base plate, and its pinion gear meshes with
the ring gear of the turntable bearing to rotate the turntable.
The swing gearbox utilizes double reduction planetary
gearing. The multi-disc swing brake assembly is an integral
part of the swing gearbox and is located between the swing
motor and the swing gearbox. The brake mechanism is a
disc pack that is hydraulically released and spring applied.
Maintenance
NOTE: The swing brake can be removed and
disassembled independently of the swing gearbox.
