我公司现有2台抚挖QUY400型履带式起重机,该机具有良好的起重性能和操作性能。但是在转场时需对其上、下车体进行分解,再由拖车运输。该机在分解上、下车体过程中,常因U形锁块不能顺利拔出而造成停工,导致吊运机械和人工的浪费。为此,我们根据该机车体连接机构的特点,对其上、下车体分解方法进行了改进。1.车体分解步骤该机上、下车体分解步骤如下:为有利于上、下车体分解,将臂杆、配重和履带等部件拆除,回收下部4个液压缸将整机重心降低。微调支腿缸,辅以水平仪检测,使整机处于水平状态。如图1所示。将100t汽车起重机设置在主机前部,以主
My company has two QUY400 crawler digging crawler cranes, the aircraft has a good lifting performance and operating performance. But in the transition need to its upper and lower body decomposition, and then by trailer transport. The machine in the decomposition, the process of getting off the body, often because of the U-shaped lock block can not be pulled out and caused the work stoppage, resulting in lifting machinery and manual waste. To this end, we based on the characteristics of the locomotive body connection mechanism, its upper and lower body decomposition method has been improved. 1. Car body decomposition steps The aircraft, the body decomposition steps are as follows: In order to facilitate the upper and lower body decomposition, the boom, counterweight and crawler and other components removed, the lower part of the recovery of the hydraulic cylinder 4 will reduce the overall center of gravity. Trim legs cylinder, supplemented by the level of detection, so that the machine is in a horizontal state. As shown in Figure 1. The 100t truck crane set in the front of the host to the main
