ABSTRACT:
A hydraulic system for a weight-load transferring mechanism for a vehicle in which a pivoted frame carries wheels and the hydraulic system raises and lowers those wheels. The system employs a directional control valve for switching the supply of pressurized hydraulic fluid from one side to the other of the operating cylinder and piston assembly without depressurizing the entire system and an accumulator is continually connected to the pressurized side for supplying the necessary fluid when switching from one mode of operation to another. The desired predetermined pressure in the system is maintained by a pressure switch operating a solenoid dump valve to allow continuous operation of the pump.
