Thomson Warner H-Track electro-hydraulic linear actuators

Thomson Warner H-Track electro-hydraulic linear actuators can move loads of up to 2177 kg from a compact mounting envelope. The actuators are suitable for space-constrained applications requiring high load handling and shock resistance.

Hydraulic cylinder-based systems require a complex assembly of hoses, pumps, valves and reservoirs. This infrastructure can be costly to install, operate and maintain, and the fluid itself requires careful handling. Thomson Linear H-Track actuators resolve this issue with a miniaturised hydraulic pump that is powered by a DC motor. The pump, cylinder and reservoir are a single unit that fits into a small housing about the size of a screw-type actuator. This hybrid actuator has a force rating of 21.35 kN and can achieve travel speeds of nearly 100 mm per second. Users can select between motors and pumps to optimise for higher load capacity or higher speed than can typically be attained with ball screw-based designs.

Using hydraulic power to create linear motion also has a cushioning effect that enables the system to absorb shock loads that might otherwise bend the ball screw or the extension tube, especially if the shock load occurred while the actuator was extended.

The ability to configure multiple pump and cylinder sizes enables Thomson to create H-Track iterations with various levels of speed and load capacity. Its pumping and reservoir architecture minimises components and optimises the volume/pressure differential. A split-tank shuttle valve with back pressure relief adds further efficiencies.
