The Petzl Micro Traxion Pulley is a compact, ultralight (85g) progress capture pulley designed for climbers, rescuers, and industrial professionals. Built for maximum hauling efficiency (91%), it’s 50% smaller and lighter than the MINI TRAXION, making it a top choice for weight-conscious expeditions.
Compatible with 8–11 mm ropes, this pulley is engineered to perform even in extreme environments like wet, muddy, or frozen conditions. The lockable cam mechanism allows it to function as either a standard pulley or a progress capture pulley, offering unmatched versatility in crevasse rescue or technical rope systems. If you're building a hauling system, this device pairs perfectly with other climbing pulleys and rope-access gear for alpine or rescue setups.
