SWING MACHINERY

Two planetary swing gearboxes, each driven by a vertically mounted motor, are mounted on either side of the revolving frame. Dual output shafts from each gearbox are splined to pinions which engage the swing rack.

Bolt-on mounting permits easy field exchange or replacement of either the planetary gearboxes or the splined pinions. Check the magnetic plug in each gearcase at each scheduled maintenance.

The four pinions result in lower shared tooth loads for longer pinion and rack life. A spring set air released plate disc brake is mounted on each of the two swing motors.
