Parking Brake System

1. Theory of Operation

The parking brake is an electrically released disk brake
mounted on the drive motor armature for increased braking
force through the transmission. The parking brake is applied
when the control handle is returned to the upper rest position
or in the bottom 8 degrees of the operating range. The brake
may be released when the control handle is moved as little as
6 degrees and travel request is made to allow for reduced
speed operation with the handle in near-vertical position for
greater maneuverability. Normal stopping during truck
operation is accomplished by reversing the travel controls
(plugging) and activating the inductive, regenerative braking
through the motor.
