ABSTRACT:
A pair of fluid operated cylinder assemblies are secured between the bunk of the trailer and a rear frame portion. An auxiliary motor, a pump driven by the motor, a reservoir, and a valve operated by solenoids to control driving functions for the pair of fluid operated cylinder assemblies is supported on the trailer. Control of the electric motor and the solenoids is accomplished by a switch located in the tractor and connected to the motor and solenoids by electric wires extending between the trailer and the tractor. The solenoids may be operated by radio receivers and remote transmitters rather than by a switch in the tractor.
