Petzl NANO TRAXION

The Petzl NANO TRAXION is an ultra-lightweight, compact progress-capture pulley designed for rescue systems. At only 53 g, it combines a toothed progress-capture cam with a high-efficiency sheave running on sealed ball bearings.

It delivers 91% efficiency and works on frozen or muddy ropes. Rope-installation diagrams are engraved inside the pulley for reference during setup.

NANO TRAXION versus MICRO TRAXION

Selection guidance

Both devices provide 91% rated sheave efficiency and are designed to work on frozen or muddy ropes. NANO TRAXION reduces weight and packed size, while MICRO TRAXION adds the ability to lock its cam open and operate as a simple pulley.

Choose NANO TRAXION when minimum weight is the priority and progress capture is required throughout the intended setup. Choose Micro Traxion when the system benefits from a larger sheave and lock-open simple-pulley mode.

These are specialized life-safety devices. Users must obtain appropriate training, follow Petzl’s technical documentation, and verify every component in the complete system.
