Petzl pulley Petzl Mobile YELLOW – single pulley for ropes, brand Petzl

Petzl Mobile YELLOW is a compact single pulley designed for use with ropes in rigging, hauling and redirect systems. The device provides a rotating sheave that reduces friction and permits smooth rope movement when changing direction or creating mechanical advantage. Intended as a component in rescue, work-at-height and recreational rigging configurations, this pulley offers a lightweight, easy-to-integrate solution for systems that require a reliable rope-bearing element.

Advantages

The Petzl Mobile YELLOW features a low-profile aluminium frame and a precision-machined sheave that rotates freely to reduce rope wear and effort during hauling. Its compact design allows placement in confined rigging setups and the pulley accepts a range of single ropes used in rescue and work-at-height scenarios. The construction balances strength and weight, making it suitable where a lightweight yet dependable pulley is needed.

Suitable for

• Redirecting rope direction in hauling and rigging systems
• Part of mechanical advantage systems for hauling or lowering
• Rescue and emergency rope systems where a single rotating sheave is required
• Work-at-height applications requiring a compact pulley for rope movement
• Recreational rigging where a small, lightweight pulley is appropriate

When it may not be suitable

This single pulley is not intended to replace purpose-built multi-sheave or progress-capture pulleys used for complex hauling systems requiring integrated ratchets or rope-grabbing devices. It is designed as a rope-guide and mechanical advantage component, not as a primary fall-arrest device or belay with automatic locking.

Key specifications

• Type: single pulley with rotating sheave
• Material: aluminium frame and sheave (metal components for strength and light weight)
• Compatibility: for use with single ropes in rigging and hauling systems
• Use cases: redirect, haul, mechanical advantage, rope guidance
• Design: compact, low-profile form factor for constrained rigging

How to use

Install the Petzl Mobile YELLOW into a rigging system by threading the working rope over the sheave and securing the pulley to an anchor point or carabiner through the attachment hole. Ensure the pulley is oriented so the rope runs smoothly over the sheave and that the chosen anchor and connectors are rated for the planned load. Inspect rope alignment and sheave rotation before applying load and monitor for debris or damage during use. Use the pulley as part of a complete system that includes appropriate connectors, anchors and backup safety measures.

What to consider before purchase

• Confirm compatibility with the diameter and type of rope you will use
• Check that the pulley’s intended role (redirect/haul) matches your system requirements
• Ensure other components (anchors, carabiners, connectors) have adequate strength ratings
• Verify that a single pulley without progress-capture suits your hauling or rescue scenario

Usage recommendations

Use Petzl Mobile YELLOW as a component within a complete rigging or hauling system. Regularly inspect the sheave, frame and rope contact surfaces for wear, remove debris before operation, and follow manufacturer guidance and applicable safety standards for rescue and work-at-height procedures.
