Aluminum Alloy 360° Universal Parallel Pulley Series

A 360° swivel parallel multi-sheave pulley designed specifically for heavy-duty rope rescue, hauling systems, and tripod/multi-pod lifting systems. It supports the rapid setup of high-mechanical advantage systems such as 4:1 and 5:1, and is widely used for fine-tuning stretcher orientation, lifting and transferring heavy loads, and controlled lowering. The integrated 360° smooth-swivel top attachment point allows for self-adaptive orientation based on the hauling angle, effectively eliminating rope tangling, flange abrasion, and uneven loading when using parallel lines, significantly improving rope operation efficiency.

Key Features

• 4:1 / 5:1 High-Advantage System Hub: The parallel double and triple sheave structure allows ropes to enter and exit in parallel without overlapping, drastically reducing friction loss and simplifying the setup of high-advantage hauling systems.

• 360° Swivel Self-Adaptive Attachment: The top swivel ring rotates instantly to align with the direction of the load, preventing rope twisting, edge abrasion, or jamming.

• Versatile Rescue Adaptation: Highly suitable for fine-tuning the balance/tilt of rescue stretchers, anchoring at the top of rescue tripods, and for the lifting and controlled lowering of heavy loads.

• High-Visibility Finish: Features high-saturation, job-site identification colors (vibrant orange for the double pulley / bright yellow for the triple pulley) for rapid identification of sheave configuration in complex systems or low-light environments.

• Rugged, Wear-Resistant Construction: Precision-crafted from high-strength aluminum alloy, the body is impact-resistant and durable, ensuring smooth and stable performance under heavy lifting loads.
