Heavy-duty off-road rescue pulleys are essential rigging components for off-road vehicle self-rescue and towing operations.

Overview of Design and Structure

1. Main Body: A bright orange, high-strength forged carbon steel housing; the orange finish allows for quick identification in muddy or wooded outdoor environments. The housing features a ribbed design to enhance impact and crush resistance.

2. Dual Lifting Eyes: The two ring-shaped lifting points at the top of the unit are used with carabiners or snap hooks to connect to anchor points.

3. Center Pulley Disc: A pulley with galvanized or color-coated metal bearings; winch cables or nylon synthetic ropes can be secured in the pulley groove and slide through it.

4. Center Pin: A large, color-coated metal rivet or pin that secures the pulley and withstands immense tensile force.

Functions and Applications

Force Multiplication: When connected to a winch system, it doubles the winch’s pulling force, making it ideal for extricating heavy-duty vehicles.

Changing the Direction of Force: Adjusts the angle of the steel cable to prevent damage to the winch caused by lateral forces.

Applications: Off-road recovery, truck/UTV/ATV rescue, tree hauling, and construction lifting and towing.

Compatibility: Synthetic nylon ropes, traditional steel cables (generally compatible with ropes ≤14 mm in diameter)

Common Specifications

- Typical rated working load: 11 metric tons (25,000 lbs); breaking strength approximately 20 metric tons; a 15-metric-ton version is also available.

- Material: Forged steel with a powder-coated finish for rust prevention.
