1.升降貨梯上升時車身翻轉(zhuǎn)的控制。在系統(tǒng)中選用液壓鎖組合元件，使兩個活塞能平穩(wěn)地停留在任意高度位置，兩個油缸的上下腔均有一定的背壓，不會因車頭重、車尾輕而翻轉(zhuǎn)液壓鎮(zhèn)具有定位準確、牢固的特點，并無浮動現(xiàn)象發(fā)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.升降貨梯下降時抖動噪聲的防止。改進系統(tǒng)液控單向閥，經(jīng)過改進，該偏載荷液壓升降機在汽車總裝線上已經(jīng)運行了兩年多，運動平穩(wěn)無噪聲，在微機系統(tǒng)的控制下實現(xiàn)自動網(wǎng)絡運行，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.液壓升降貨梯是一種應用廣泛的高空作業(yè)設(shè)備，適合于機場候機樓、飛機搶修,車站、碼頭、商場、體育場館、小區(qū)物業(yè)、廠礦車間等較大范圍的高空連續(xù)作業(yè)。 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.
