1.升降货梯上升时车身翻转的控制。在系统中选用液压锁组合元件，使两个活塞能平稳地停留在任意高度位置，两个油缸的上下腔均有一定的背压，不会因车头重、车尾轻而翻转液压镇具有定位准确、牢固的特点，并无浮动现象发生。Control of vehicle body turning over when the elevator is rising. The selection of hydraulic lock combination element in the system, the two pistons can stably stay at any position, the upper and lower two cylinders have certain pressure, not because the car head and the tail light and turning hydraulic town has accurate and firm positioning characteristics, no floating phenomenon.

2.升降货梯下降时抖动噪声的防止。改进系统液控单向阀，经过改进，该偏载荷液压升降机在汽车总装线上已经运行了两年多，运动平稳无噪声，在微机系统的控制下实现自动网络运行，效果很好。The prevention of jitter noise during the descent of the elevator. To improve the system of hydraulic control valve is improved, the partial load of hydraulic lift in the automobile assembly line has been running for more than two years, moving smoothly without noise, realize the automatic control of the microcomputer system in network operation, the effect is very good.

3.液压升降货梯是一种应用广泛的高空作业设备，适合于机场候机楼、飞机抢修,车站、码头、商场、体育场馆、小区物业、厂矿车间等较大范围的高空连续作业。 Hydraulic elevator is a kind of widely used aerial equipment, suitable for airport terminal building, aircraft repair stations, docks, stadiums, shopping malls, residential property, factories, workshops and other large-scale aerial continuous operation.
