摘　　要：9MN提梁机是铁路建设的重要设备,而液压卷扬系统又是整个提梁机的最关键部分,提高该系统的可靠性具有重要意义。根据设计可靠度对该部分进行可靠性分配。实际运行情况表明,对液压卷扬系统进行可靠性分配后,系统的故障明显减少,整机性能得到很大的改善,整个系统的可靠性大大提高。9 MN-gantry-erane is an important equipment for railway construction. Hydraulic winch control system is the most critical part of the whole gantry-crane. It is significant to improve the system reliability. The allocation of the system reliability was done according to design reliability. The actual operation situation shows the system failure reduces significantly, machine performance is improved and the reliability of the whole system is increased after allocating the reliability of the hydraulic winch control system.
