Accessories available for the Zippey Trolleys

ARC – Anti Roll Back Cam. This innovative add on solves many of the issues associated with modern zip lines. Riders who reach the egress platform can roll back out onto the line requiring staff intervention. The ARC ensures that the rider remains in position over the egress platform by camming against the zip line cable maintaining their position.

Handle Accessory – There is now an available handle accessory for the Zippey making it possible for riders to ‘steer’ into the arrival station.
