Tractel Dynasafe™ HF 05/3 Tension Load Limiting Cell – 4,000 lb Capacity (Model A, Dual Trip Points, No Monitor) - 43528

Product Description

The Tractel Dynasafe™ HF 05/3 Tension Load Limiting Cell is a robust safety device that has been designed to give users staged overload protection for lifting and tensioning systems. This Model A version features two independent trip points. This allows a pre-warning activation at the first threshold and a full stop or alarm at the second. Its integrated micro switches eliminate the need for a separate monitor, making it a self-contained, easy-to-install safety solution.

With a 4,000 lb (1,814 kg) capacity, the HF 05/3 is ideal for medium- to heavy-duty hoists, cranes, winches, and tensioned wire-rope systems. Installed directly in the load path, it delivers immediate mechanical overload detection to help prevent equipment damage, unsafe conditions, and costly downtime.

Engineered for precise and repeatable performance in industrial environments, the HF 05/3 combines compact design, dual-trip functionality, and durable construction for reliable staged load-limiting control.
