Haldex Commercial Vehicle Systems announced that it has added the ILAS E Air Suspension Valve to its Trailer Roll Stability System. The valve can control the position of the lift axles through an electrical connection; a 12V power supply is needed to keep the lift axles in the raised position. When power is removed, the lift axles will be lowered automatically; this can be controlled simply via an electrical switch.
When coupled with the Haldex TRS System, the lift axles can be controlled to raise and lower automatically as the air suspension reacts to changing loads in the trailer; the lift axle and wheels are not subjected to wear when the vehicle is empty. According to Haldex, the ILAS E / TRS System can be adjusted to react at various pressure conditions, making the system versatile for single- or multiple-lift axle trailers.
The company says the ILAS E simplifies the lift axle system with four push-to-connect fittings and a standard DIN electrical connection. For more information, go to www.haldex.com.
