主　　题：radio remote controlling construction machinery proportional controlling three-way proportional pressure reducing control 

摘      要：The working principle of radio remote controlling of construction machinery should be that signals of the radio wave from the transmitter obtained in the receiver were controlled and then changed into electronic analog or digital signals which can be used to drive different actuators and mechanisms of the *** vehicle could be acted by following the controlling instructions sent by the *** best operation mode of construction machinery is suitable not only to manual operating but also to remote controlling in the same *** design methods of the hydraulic system used for the radio remote controlling of construction machinery are *** design methods of hydraulic circuits for the actuators controlled by solenoid on-off type valves,hydro-electronic multi-way proportional valves,closed loop proportional servo driver or three-way proportional reducing valves are discussed in detail (with real example).The design methods of the power shift transmission of electro-hydraulic controlling,the devices of braking and the directional streering are discussed in this paper.
