中文摘要：

YP2.0-A集材索道遥控跑车是在YP2.5-A集材索道遥控跑车的基础上进行改进设计的,具有利用液压制动取代半自动跑车在索道线路中的止动器、可在索道沿线任意点停留、自动起落钩的优越性。通过对YP2.0-A遥控跑车主要技术参数及其工作原理进行系统分析,重点对液压系统进行改进设计,提高液压系统的灵敏性、安全性和可靠性能,实现索道集材运行的自动化和精确控制。通过对13条不同集运量的索道作原始纪录和成本统计分析处理,得出索道集材成本为110～ 130元·m-3。该遥控集材索道非常适合人工林集材作业,具有良好的生态效益、经济效益和社会效益。

英文摘要：

YP2. 0-A is designed on the basis of YP2. 5-A skidding ropeway remote control carriage,which has the superiority that can substitute the stopper of semi-automatic carriage in the line of cableway by using hydraulic braking and can stop at any position of the cableway,and the hook of the carriage can move up and down automatically. Based on the analysis of main parameters,performance and working principle of the YP2. 0-A carriage,the hydraulic system has been designed. The new system enhances the performance of sensitivity,security and reliability of the hydraulic system,and achieving the automation and precision control of skidding operation. Through statistical analysis and the original record of13 different capacity of skylines,the cost of skyline is 110- 130 yuan·m- 3. The carriage possesses a very good ecological benefits,economic and social benefits.
