TEFRA Quick Hitches

A quick hitch that goes beyond Australian standard to ensure safety

The TEFRA quick hitch is an award-winning attachment system that uses an active, dual positive locking system instead of a passive, gravity-based one, enhancing safety. It exceeds the Australian Standard AS 4772-2008, which requires both a primary retention system and a safety mechanism to prevent accidental attachment disconnection.

TEFRA’s fully automatic hydraulic design prevents attachment separation and uncontrolled swinging, even if the primary retention system fails, minimizing safety risks, especially when operating near people.

Safety First

TEFRA Quick Hitch eliminates the risk of attachment separating from the quick hitch and prevents uncontrolled movements.

Universal Pick up

TEFRA can pick up attachments from different machine manufacturers within weight range of 3 – 120 tonne.

Reliable

With only 3 moving parts and uncomplicated design TEFRA is one of the most reliable and robust Quick Hitches on the market.

Innovative Technical Features

The Hill Smart Valve

The Hill Smart Valve is a unique safety feature which prevents attachment removal in unsafe conditions. It works by recognising the correct/safe quick hitch orientation before permitting the release sequence to commence. The Smart Valve is totally enclosed within the cylinder and as such cannot be affected by contamination and requires no routine maintenance.

Active Protection System

The Active Protection System is a fully Independent secondary locking system comprising two component parts. A coil spring around the cylinder ensures that the rear hook remains in the correct position in the event of a hydraulic failure. A leaf spring on the front hook acts to maintain it in the correct position in the event of a hydraulic failure. The springs do not take the weight of the attachment, this is done by the quick hitch hooks, they are there solely to keep the hooks correctly located. In addition, the pressure exerted by the springs provides a ‘Return to Safe’ feature ensuring that the hooks always remain in, or return to, the closed position.
