T he vehicle could be acted by following the controlling instructions sent by the operator. The best operation mode of construction machinery is suitable not only to manual operating but also to remote controlling in the same vehicle. The design methods o f the hydraulic system used for the radio r emote controlling of construction machinery are discussed. The design methods o f hydraulic circuits for the actuators controlled by solenoidn off type valves, hydro-elect ronicmuti-way proportional valves, closed loop pro portonal servo driver o r three-way proportional reducing valves are discussed in detail ( with r ea l example) . The design methods o f the power shift transmisson of electro hydraulic controlling , the devices o f braking and the directional streering are discussed in this paper.
