一台使用已十几年的UC-25型轮胎式起重机,其主要传动部件及相对运动件有形磨损加剧,并相继出现故障,特别是起升、变幅、旋转、行走4大工作机构的离合器液压缸漏油问题长期未得到很好的解决。为此,我们对原液压缸总成中的柱塞结构进行了改进,使漏油的故障得以消除。1液压缸漏油
A use of more than 10 years have been UC-25-type tire cranes, the main transmission parts and relative moving parts tangible wear and tear, and have failure, especially the lifting, luffing, rotation, walking four work-organization clutch Cylinder oil spill problem has not been well resolved. For this reason, we improved the plunger structure in the original hydraulic cylinder assembly to eliminate the oil leakage fault. 1 cylinder leakage
