Raise and Lower Self-Steering Trailer Axles Automatically With New Lift Axle Control
CANTON, OH. – Eliminate the operator’s role in raising and lowering self-steering trailer lift axles with Hendrickson’s new Automatic Lift Axle Control.

Available as an option on new Hendrickson trailer suspension systems or through the aftermarket network for retrofitting, the automatic control electronically triggers the axle lift mechanism when the trailer travels rearward and starts the axle dropping with forward movement.

Compatible with any lift mechanism equipped with an electro-pneumatic control, Hendrickson’s Automatic Lift Axle Control answers new Canadian control requirements for liftable / steerable axles. The unit operates without driver intervention and without controls in the cab – fully automating the control of the lift axle.

A wheel-end sensor reads the ABS tone ring triggering after three feet of rearward travel to activate the lift mechanism. Eighty feet of forward travel automatically keys the lowering of the axle.

Hendrickson offers a wide variety of liftable INTRAAX® suspension systems; lift mechanisms including the lightweight, compact UNDER BEAM LIFT™ (UBL™), and a complete line of electric controls.

The Automatic Lift Axle Control Kit (EKAD0001) includes direction sensor, electronic control unit and wiring harness. A kit incorporating a back-up alarm is also available.

A stand-alone trailer system, the easy-to-install control requires no communication with the tractor and features a compact, modular design.
