BACKSTOPPING FOR HIGH SPEED OVERRUNNING (OVERRUNNING AT 700 TO 3,600 RPM)
Inclined Belt Conveyors In this application, the gear reducer is tasked with driving a large scale inclined conveyor system. The Cam Clutch is installed to prevent the conveyor from rolling backwards in the event of stoppage or overload. As depicted in Figure 12 , the Cam Clutch is mounted directly onto the reducer to prevent damage that would result due to reverse rotation.

Pump/Compressor Systems There are many applications in which multiple pump or compressor systems are feeding into the same line. These are common in applications where energy savings is required, or emergency backup/redundancy is highly desired. When the system is shut down, or another pump comes on line, there may be a tendency for a given pump to back-spin when not running. Allowing this to happen may result in damaging the pump or compressor. Installing a backstopping Cam Clutch can prevent this. Please reference Figure 13 for an illustration example.
