Toroidal Systems Ltd has developed a patented technology with its unique toroidal shaped rotary hydraulic actuator - called the Toroidal Ram.

The Toroidal Ram is a world first curved ram, hydraulic rotary actuator capable of angular rotation up to 100 degrees and has been designed for use in high torque, heavy duty applications.

The Toroidal system utilises two single acting, toroidal shaped cylinders that oppose each other to create rotary motion in both directions. Each cylinder employs similar operating principles to that of a single acting, linear hydraulic cylinder, thus benefiting from a robust and proven design that has been used in engineering applications for decades. This basis of the Toroidal Ram design lends itself to applications involving a high and constant torque output.

Toroidal Ram Systems is focused on partnering with others that would like to adapt the Toroidal Ram Technology into various engineering industries and applications.


The Toroidal Ram operates similar in principle to a single acting hydraulic cylinder, which are known for their simplicity and robustness. Rather than being linear, each Toroidal Ram cylinder features a curved cylinder body which houses a single piece, curved hydraulic rod.


The Toroidal Ram utilizes two single acting toroidal shaped cylinders that oppose each other to create rotary motion in both directions - current output is 100 degrees. It is compact, robust and has zero creep.


The Toroidal Ram Actuator has been developed for use in the earth moving industry, specifically for tilting hitches on excavators. The construction industry exposes the Toroidal Ram to overloading, rough handling, harsh weather and dirty environments. Testing in this industry has put the technology through its paces and has resulted in a proven working product.


We are here to help you utilise our technology in your design.

We have been through the process of commercialising a product in which the Torlite Actuator System has been incorporated. We are experienced on all aspects of bringing a product to market and are able to support any licensee of our technology throughout this process:
