TEFRA Coupler

TEFRA Coupler

The TEFRA Coupler have a duel locking system to ensure the highest level of safety, keeping the attachment permanently engaged in all orientations and applications. The primary locking system features the uniquely designed set of hooks that hold the attachment securely in place. The secondary locking system is a single leaf spring that applies constant pressure to the front hook and a coil spring that does the same for the back hook. These springs have been tested vigorously to ensure they are both in far excess of any strength or safety requirements.   

Another major safety feature of the TEFRA Coupler is the Hill Smart Valve. This innovative and effective solution ensures that the attach and release sequence of attachments can only be performed when the Coupler is orientated toward the operator in a curled position. The Hill Smart Valve requires no routine maintenance and is not prone to external damage or contamination during use as it is protected within the cylinder design of the Coupler. Another innovative factor is the Reverse Hose System that ensures the attachment hoses don’t become entangled in excavator linkage which often caused major hose damage with other couplers. 

There is little to no maintenance required in the whole TEFRA range.
