Safety Cams for Mechanical VRCs

FEATURE PREVENTS CARRIAGE DROP IF CHAIN BREAKS

All PFlow Industries VRCs that use chains to lift and lower the carriage (mechanical lifts) are fitted with safety cams.

In the unlikely event of a lifting chain break, the safety cam will immediately and automatically rotate into position. As the safety cams rotate into position, the downward pressure of the carriage forces them into the flanges of the guide columns, preventing carriage descent.

When chain tension is returned to normal, the cams automatically rotate back to their inoperative position, allowing the VRC to resume normal operation.

On the M Series and F Series mechanical lifts, slack or broken chain conditions are sensed by a switch on the chain tensioner assembly which cuts power to the drive.

All units should be fully inspected before resuming service.
