TEFRA – an industry first

TEFRA’s dual safety features are unique within the industry.

Primary Safety Systems

This consists of a uniquely designed set of hooks powered by a single cylinder and high specification hydraulic controls that lock the attachment securely into place.

The intrinsic feature of the hooks is their shape – they are individually designed to tightly hold their respective pins against the body of the Coupler. This secure and failsafe retention means the attachment stays in place in all orientations and operating conditions.

Secondary Safety Systems

Our Active Protection System – APS consists of 2 separate powerful springs that apply pressure to the hooks to ensure attachment retention at all times.

A single leaf spring applies constant pressure to the front hook. This compact and durable spring ensures the hook stays in place at all times. A coil spring serves exactly the same role in relation to the rear hook.

Both springs are individually rated far in excess of any required strength and safety legislations, yet they remain as light as possible in order to satisfy Hill’s constant drive to create ‘strength without weight’ across all product ranges.
