MAIN MOTOR PROTECTION MECHANISM

2.3 MAIN MOTOR PROTECTION MECHANISM
The main motor [A] drives the pressure cylinder [B] and the drum. When the
pressure cylinder or drum is locked, the torque limiter [C] stops drive from the main
motor gear from being transmitted to these parts. This prevents the mechanism
from being overloaded.
