Because YP2.5-A type remote control car exists several problems: structure is complex, volume is large, weight is bulking, operating speed is low, area of application is narrow and costing is high. YP-2 remote control car was designed based on productive experiments. YP-2 type remote control car, the structure and performance parameter of JSD3-2 type winch were analyzed. Application condition of SJ-2/2 type remote control car in plantation logging clearing was presented from technical reliability and economic rationality. According to comparison with the traditional cable crane, the SJ-2/2 type remote control car ropeway has characteristics of simple ropeway system, convenient installation and teardown, simple operation as well as high degree of automatization, advanced technology and high production efficiency, low operating cost, remarkable economy benefit.
