Heavy-duty Electric Power Steering (EPS)

Steer-by-wire electric steering for large vehicles

First EPS for heavy-duty vehicles. Now it’s possible to replace conventional hydraulic power steering with a powerful and robust electromechanical system designed for heavy-duty applications. The Cascade STEERING system is compact, efficient, fast, and accurate. Unlike other EPS steering solutions, it doesn’t suffer from degradation due to wear from shock-loading.

EPS for improved steering accuracy

In autonomous vehicles, controllability is key for safe and reliable operations. The Cascade Steer-by-wire system's is superior when it comes to positioning accuracy. And with its resilience to external forces such as shock-loading, you benefit from longer service intervals and lower maintenance costs. Cascade Steer-by-Wire is equally suited for manual, autonomous, and hybrid electric vehicles.


Powerful enough to handle off highway vehicles operating in tough terrain

Absorbs shock-loading

cdGear's built-in torsional flex absorbs shock loads and saves gear teeth


Superior energy efficiency compared to conventional hydraulic systems

Product features

Compact design

Compact solution for plug-and-play installation without the need for auxiliary mechanical systems.

Cheaper assembly

Compact modular design allows for plug-and-play installation. No pipe works required.


Acceleration, motion, and deceleration profiles curves are easily tailored for specific applications.

Long life

It is designed for life-long operation with negligible maintenance requirements.

Multi-mode operation

Equally suited for manual, autonomous and hybrid electric vehicles.

Built-in sensors

Cascade STEERING uses separate dual encoders for micrometer positioning of the rack.


Superior response time allows for rapid steering maneuvers.


No hydraulic fluids mean a no risk of oil spills.

No overshoot

The precision of electric actuators eliminates the problem of moving past the target position and then having to reverse. Our actuators hit the target position directly every time.

Precise power steering for heavy-duty vehicles

As heavy-duty vehicles go electric and become more autonomous, there's a demand for alternatives to the conventional hydraulic systems usually found in everything from mining and container loaders to heavy trucks.

For electric heavy-duty vehicles

Material handling

Tight spaces, 24/7 operation, and precise motion make the Cascade STEERING system ideal for everything from forklifts to container trucks.


Cascade STEERING is well suited as a non-hydraulic electromechanical steering system for electric buses.

Mining vehicles

Heavy-duty machinery working in tough environments place extreme demands on their control systems. With Cascade STEERING you get a precise and low-maintenance electric steering system you can rely on.

Airport vehicles

Airplane tow tractors, baggage tractors, and utility vehicles can become fully electric with Cascade STEERING systems, with increased overall efficiency and reduced maintenance requirements.

Commercial trucks

A Cascade STEERING system eliminates the need for hydraulics and improve both response time and accuracy. 

Cranes and utility vehicles

Utility vehicles can now replace their electricity-driven hydraulic steering with a fully electric Cascade STEERING system.
