Allient EPS Electric Steering Systems Review: Specs, Price and Applications
Allient EPS combines a steering motor, gearbox and controller, with an optional output pinion. Three frame sizes and 16 listed models cover material-transport steering duties. Standard battery classes include 24, 36 and 48 VDC, with higher-voltage options available for selected configurations.
Quick Verdict
A relevant integrated steering assembly for AGVs and industrial trucks when the required steering torque, vehicle geometry and control architecture are defined. Its optional turning-wheel absolute-position function is a steering-position feature, not a replacement for a complete vehicle safety design.

Design and Engineering Assessment
Steering torque should be checked at low vehicle speed, including the tire contact patch and actual axle load. Static tire scrub can demand substantially more torque than steering while rolling. A compact motor package is useful only if the gearbox output and mounting structure support that load case.
An absolute turning-wheel position function can simplify restart logic, but steering recovery still depends on the machine controller’s state handling. Power interruption, CAN timeout and a disagreement between commanded and observed steering angle need defined responses before the vehicle resumes motion.
Steering Load and Vehicle Geometry
Electric steering should be sized around the vehicle, tire and floor interaction. Axle load, tire contact patch, steering geometry and the required angular rate determine the output demand. A stationary turn on a high-friction floor can be more demanding than a turn while rolling. The assessment should include representative worst-case maneuvers rather than an unloaded bench rotation.
The mechanical installation must support the forces transmitted through the steering linkage and output gear. Mounting stiffness, alignment and backlash influence how accurately the commanded angle becomes a wheel angle. Cable routing must also accommodate the motion envelope without repeated strain or interference with the steering mechanism.
Power and Supervisory Control
Battery voltage varies with state of charge and load, so the selected steering assembly and its supply arrangement need a compatible operating envelope. The electrical design should account for protection, grounding and simultaneous vehicle loads. Integration is simplified by a combined motor and controller, but the surrounding vehicle still has to provide a suitable source of power and a clear enable sequence.
The supervisory controller needs defined behavior for loss of communication, a steering fault and restart after power interruption. Position feedback should be interpreted in the same coordinate convention as the vehicle guidance system. A successful CAN connection is only the beginning; message timing, diagnostics and fault responses determine whether the steering function behaves predictably in the vehicle.
Validation in the Actual Vehicle
Evaluate steering under representative cargo load, floor conditions and operating temperature. Check low-speed turns, direction reversals and the steering response during a controlled stop. The required safe behavior depends on the full vehicle architecture and must be established for that application rather than inferred from a component feature.
For serviceability, retain the steering offsets, mounting details, network configuration and calibration procedure. Replacement should restore the approved relationship between sensor angle, actuator angle and wheel angle. A compact integrated package can reduce assembly work, while disciplined configuration records keep that benefit through the vehicle’s maintenance life.
Applications and Selection
Electric steering for pallet lifters, AGVs, AGCs and industrial reach trucks.
For Allient EPS Electric Steering Systems, define the actual machine duty before selecting an ordering configuration. Include the required operating point, available installation space, environment and control interfaces. The specification table describes the product or family; the surrounding machine determines which of those features matters for the intended job.
Price and Value
Price: Request a quote for the exact configuration. Compare the product, compatible control equipment, required mechanical parts, cabling and commissioning as one installed system. A component price alone does not represent the cost of a working automation axis.
Evaluate an alternative against the same duty and acceptance criteria. Match the continuous operating requirement first, then compare transient capability, feedback, mechanical fit and support. This avoids choosing between superficially similar products whose ratings describe different operating conditions.
Pros and Cons
Advantages
Steering motor, reduction and control in one assembly
CAN diagnostics and selected absolute-position options
Limitations
Vehicle steering loads require application sizing
Position sensing alone does not establish vehicle-level safety
