工程自卸车的液压举升机构把货厢举升到某一所需位置时,货厢发生下滑现象,北方多称此故障为“溜缸”,南方个别服务站称之为“落顶”。这种故障影响了自卸系统的正常工作,笔者根据多年的售后维修经验,分析出故障产生原因,可快速诊断并进行维修。液压举升系统基本回路简介自卸车 When the hydraulic lifting mechanism of the engineering dump truck lifted the cargo box to a desired position, the cargo box slippage occurs. In the north, the fault is called “slip cylinder”, and the individual service stations in the south call it “falling roof.” This failure affected the normal operation of the dump system, the author based on many years of after-sales maintenance experience, analysis of the causes of failure can be quickly diagnosed and repaired.
