Petzl MICRO TRAXION

The Petzl MICRO TRAXION is a compact, lightweight progress-capture pulley designed for crevasse rescue, hauling, self-rescue, and emergency rope ascent. Its cam can be locked open, allowing it to function as a simple pulley when progress capture is not required.

Sealed ball bearings provide 91% efficiency, and the toothed cam with a self-cleaning slot is designed to work on frozen or muddy ropes.

Detailed use cases

• Crevasse-rescue hauling systems
• Progress capture in mechanical-advantage systems
• Self-rescue and emergency rope ascent
• Pack and equipment hauling
• Simple-pulley use with the cam locked open
• Loss-resistant setups using the connection hole and a compatible carabiner with cord

Users must be trained and competent, verify full-system compatibility, and follow Petzl’s technical notice.
