TEFRA - Fully Automatic Quick Hitch

Safety, efficiency and savings in installation and maintenance are the maxims of TEFRA hydraulic quick couplers. Designed to increase safety and efficiency at work, TEFRA quick couplers adapt to machines from 3-ton mini-excavators to large excavators of up to 120 tons of any brand on the market.

Primary Locking System

The dual safety features of the TEFRA are unique within the attachment industry. The primary safety system 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 fail safe retention means the attachment stays in place in all orientations and operating conditions.

Secondary Locking System

Our Active Protection System (the 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 strength and safety requirements, yet they remain as light as possible in order to satisfy constant drive to create, ‘strength without weight’ across all product ranges.

Smart Valve

A unique, fully patented major safety feature of the TEFRA Coupler. The Smart Valve is a simple, patented, totally effective solution ensuring that the attachment and release sequence cannot be started until the Coupler is orientated towards the operator and close to the ground. This eliminates the possibility of an unsafe situation occurring. The Smart Valve’s compact design means it can be totally enclosed within the hydraulic cylinder at the centre of the Coupler; this protected position means it cannot be contaminated. It requires no routine maintenance and works in conjunction with other warning systems such as audible indicators to ensure safe and easy operation.
