Heavy-duty opening pulley | Freehook® HK

Range : Lab Innovation | Lifting, Reeving & Technical Rescue

Concept description: The Freehook® is a new-generation opening pulley combining a low-friction open ring and a high-resistance Dyneema® textile connector. Designed for maximum efficiency in the field, it instantly "hooks" a flying rope, offering an ultra-light and robust alternative to traditional mechanical opening blocks.

A multi-trade tool for control & return: Its versatility makes it an indispensable piece of equipment for a wide range of applications:

• Energy & Networks (RTE, Enedis): Ideal for tensioning lines and lifting equipment at height.

• Off-road & Hallage: Indispensable for recovery and reeving maneuvers to increase traction force.

• Arborry & Forestry: Used as a dismantling pulley or deflection point to guide loads during felling.

• Maritime (Pilot Boats / Work): Perfect for controlling maneuvers and deflecting ropes under high tension.

• Rescue & Caving: Creates a quick haul to reel in a victim. The gear ratio halves the effort, enabling a single operator to maneuver a human load.

Features & Benefits :

• Immediate positioning: Allows the pulley to be positioned anywhere along a rope, even under tension, without needing to access the ends.

• Multi-purpose: Can be used as a deflection point, connecting element or holding brake (by doubling or tripling the rope's passage through the ring).

• Hoist system: Allows rapid creation of reeving systems for heavy loads.

• Passive safety: No moving mechanical parts for total reliability in hostile environments (mud, sand, salt).
