Petzl's Pro Traxion is a self-jamming pulley which is specialized for lifting. Its friction coefficient is very low with its 38 mm diameter sheave mounted on sealed ball bearings. An additional return point allows hauling systems to be rigged up for lifting loads up to 8 kN while staying within the limits of use of the pulley. The rope is easy to thread through the Pro Traxion due to a moving side-piece which is unlocked by pressing a button. This allows it to be threaded when it is pre-attached onto an anchor.
