TEFRA Tilt hitch system

Northern-Ireland attachment manufacturers to show TEFRA Tilt hitch system and Titan Thumb

HILL Engineering will be exhibiting their new TEFRA Tilt hitch, the award-winning TEFRA coupler and a selection of Titan buckets at Plantworx 2017. Also on show will be the recently launched Hill Titan Thumb which has been designed to add versatility and to optimize productivity for excavator operators. 

Available for machines from 3 to 20 tonnes, the Titan Thumb is suitable for a variety of materials-handling applications and can either be pin-mounted, so it can be rotated from the pin, or dipper mounted. When not in use, the Thumb retracts so the excavator can be used as normal.


The TEFRA Tilt hitch system has all the advantages of the award-winning TEFRA coupler but provides customers with the added benefit of increased productivity and versatility in multiple applications. It uses the highly reliable XtraTilt power actuator from HKS of Germany to achieve a 180° tilt function, which gives operators greater flexibility in the way they use their machines. 

The swivel mechanism of the power actuator is based on the ‘coarse-thread’ principle. The linear movement of the piston – when pressure is applied – is converted by multiple opposing coarse threads on the housing, piston and shaft to achieve powerful rotary movements. 

Hill Engineering say the simple and robust design of the TEFRA Tilt hitch, with just three moving parts, sets this product apart from those of other suppliers. In addition, the HKS XtraTilt power actuator is said to be self-lubricating and essentially maintenance- and wear-free.

The award-winning, fully automatic TEFRA coupler, which is said to have played a significant part in increasing Hill’s market share, will also be on display at Plantworx 2017.

The company says the system has proved itself to be the safest coupler on the market today, thanks to its positive locking system rather than a gravity locking system, making the crucial safety feature ‘active’ and not ‘passive’.
