PETZL Micro Traxion Pulley – Ultra-Light Progress-Capture, 91% Efficiency

PETZL Micro Traxion: Ultra-Light Progress-Capture Pulley

The MICRO TRAXION is an ultra-light (85 g) and ultra-compact progress-capture pulley designed to move smoothly along the rope. With sealed ball bearings, it delivers high efficiency—about 91%—reducing effort during progression and tensioning tasks.

A cam that can be locked in the open position lets the device function as a simple pulley when needed, adding flexibility for different rigging goals. It remains effective on frozen or muddy ropes, expanding where you can use it in challenging conditions.

Rope compatibility focuses on ropes from 8 to 11 mm in diameter, a common size range for outdoor climbing and rope-access work. The unit weighs 85 g and carries a working load of 2.5 kN per side (5 kN total) with a breaking strength of 15 kN per side (30 kN total) in standard use. Certifications include CE EN 567 and UIAA, reflecting adherence to recognized safety standards.

Key benefits

• Ultra-light and compact: 85 g with volume about 50% smaller than the MINI TRAXION.
• High efficiency: sealed ball bearings support smooth operation (approximately 91%).
• Flexible operation: cam can be locked open to function as a simple pulley, even on challenging rope conditions.
• Rope range: designed for 8–11 mm ropes.
• Durability and standards: CE EN 567 and UIAA certifications.

Real-world use scenarios

• Progress-capture setups in rope-access work, training, and rescue practice.
• Lightweight backup system where minimizing weight matters on the route or at the site.
• Quickly switching between progression and a simple pulley without swapping gear.
