The Anti-Rollback Cam (ARC)is a simple device which can be retro-fitted to the ZipSpeed and Zippey Trolleys. During normal use, the cam trails, allowing the trolley to roll forwards, unhindered. However, as soon as the trolley begins to roll backwards, the cam is activated , bringing the trolley to an immediate halt. This anti-rollback function captures the progress of the trolley, which means that even when the trolley doesn’t reach the end of the Zipline, it cannot roll backward and hence rescue distance (and therefore, rescue time) is significantly reduced.

The Anti-Rollback Cam is compatible with the Zippey Clip‘n’Zip Trolley; available in two sizes for use with 12mm & 13mm diameter cable

IMPORTANT —Smooth cable (swaged or spliced) improves the performance of the trollies and ARCs. Conversely, course-lay cables reduce the lifespan of the trollies and ARCs. Due to the many different cable types and variables affecting usage, we recommend that you carry out trial evaluations with a sample ARC on your chosen trolley and cable to ensure compatibility and suitability in the environment which you intend to use them.
