The LPU torque limiter is a mechanism designed to absorb overloads in any type of machine, therefore they are mechanical “fuses”. The LPU torque limiter only limits the torque in one direction of rotation.
When the torque is exceeded in the direction of actuation, a slip occurs between the chain sprocket, pulley, etc. and friction discs.
In the opposite direction of torque limitation, the transmitted torque has no limit.
