Class Information
Number: 198/781.02
Name: Conveyors: power-driven > Conveyor section > Live roll > Live roll drive engages, disengages, or slips responsive to load position or blockage > Friction drive slips or disengages
Description: Subject matter wherein the cylindrical motion transmitting device releases a motion transmitting force to the load conveying rollers via a coupling (e.g., friction clutch) breaking the motion transmitting force relative to one another in response to the overload caused by a desired load stoppage or weight.
