4.4.3 Multiple disc brake, support arm (travel
brake)
General
The brake is an electromagnetic multiple disc brake with multiple steel
discs.
The brake is engaged by energising the magnetic coil. The current in
the magnetic coil is regulated by a potentiometer in the brake pedal,
resulting in regulation of the brake force.
The brake acts as a secondary travel brake, along with motor braking,
and is engaged when the operator needs to brake hard, when the brake
pedal is depressed through more than 50 %.
Design
The brake is fitted in the support arm wheels on a hub with splines and
a locking shoe (j) which takes up the braking force.
