In order to reduce labor intensity and ensure safe operation a remote control system based on MCU AT89S52 was designed by using the self-propelled monorail transporter 7YGD-35 as the research object. The system is composed of the remote controller, the central processing unit and the electromotive handspike, etc. The clutch actuator, shift actuator, throttle actuator and brake actuator are designed to make accurate control, which all use the electromotive handspike as the core. The experimental results show that the control distance is as far as 300 m, and it is perfectly suitable for the transportation of mountainous citrus orchard. Therefore, there is a good prospect for the application of the system for monorail transporter. 
