A trailer (100) or other wheeled vehicle with an air suspension (12-17) is provided with a wheel rotation sensor (5) which generates a control signal causing the air suspension to be reset to an in-transport (raised) condition from a loading/unloading (lowered) condition in which the load might be damaged by movement of the trailer. An electronic control circuit (not shown) is provided with a power saving circuit which prevents repeated re-setting of the air suspension to the in-transport condition. |
