Mobile lifting platform is undoubtedly free to move. For some construction sites and highway construction, mobile lifting platform undoubtedly occupies a great advantage.

移動式升降平臺起升的穩(wěn)定性相當好，因為設備有四個支腿固定，在我們使用設備前，我們需要將設備的四支支腿打開并且固定好，緊接著我們就可以開始起升作業(yè)了。

The lifting stability of the mobile lifting platform is quite good, because the equipment has four legs fixed. Before we use the equipment, we need to open and fix the four legs of the equipment, and then we can start the lifting operation.

移動式升降平臺年終保養(yǎng)3.液壓油的油質和油位。升降機全程升起，在這位置時，液壓地面應高出箱底40～50毫米。如發(fā)現(xiàn)液壓油變暗、發(fā)粘或者有砂礫等異物，應及時更換（32#液壓油）。

Year end maintenance of mobile lifting platform 3 Quality and level of hydraulic oil. The elevator shall be lifted all the way. When in this position, the hydraulic ground shall be 40 ~ 50mm higher than the bottom of the box. If it is found that the hydraulic oil is dark, sticky or has foreign matters such as gravel, it shall be replaced in time (32# hydraulic oil).

各部位均加注一些潤滑油，延長升降機軸承使用壽命。檢查液壓升降機滾輪、中間軸及軸承，油缸銷軸及軸承，臂架鉸軸及軸承等有無磨損。

All parts are filled with some lubricating oil to prolong the service life of elevator bearing. Check the roller, intermediate shaft and bearing of hydraulic elevator, oil cylinder pin shaft and bearing, boom hinge shaft and bearing for wear.

液壓系統(tǒng)任何部位之間，卸壓，以免壓力油噴出，升降機工作臺溘然下滑。

Between any parts of the hydraulic system, the pressure shall be relieved first to prevent the pressure oil from spraying out and the elevator workbench from sliding suddenly.

升降機一旦過了保修年限，一些維修廠家可能要進行收費，如果是簡單的損壞，造成了維修大費用對于客戶來說是十分的不劃算，因此學習相應的維修知識可以減少不必要的支出。

Once the elevator has passed the warranty period, some maintenance manufacturers may have to charge. If it is a simple damage, resulting in a large maintenance cost, it is very uneconomic for customers. Therefore, learning the corresponding maintenance knowledge can reduce unnecessary expenses.

一、如果升降機突然升不起來，很明顯的聽到電機空轉，這種情況有可能是電機反轉了，此時插頭兩條線進行調轉即可，升降機可恢復升降。

1、 If the elevator suddenly fails to rise, it is obvious to hear the motor idling. In this case, the motor may be reversed. At this time, the two lines of the plug can be rotated, and the elevator can resume lifting.

二、如果升降機升降不起，也排除了電機反轉的原因，但移動式升降平臺的各部件正常，沒有找到燒毀或碰撞的痕跡，此時，我們可查看移動式升降平臺在平臺上的制動按鈕，如果此制動按鈕被按了，升降機是停止狀態(tài)不能進行任何升降，只需輕輕撥回去即可，升降機可恢復升降狀態(tài)。

2、 If the elevator can't rise and fall, the reason for the reverse rotation of the motor is also ruled out, but the components of the mobile lifting platform are normal, and there is no trace of burning or collision. At this time, we can check the brake button of the mobile lifting platform on the platform. If the brake button is pressed, the elevator is in a stopped state and can't rise and fall, just gently dial it back, The lift can be restored to the lifting state.

三、如果升降機在升降過程中突發(fā)性停止，此時可擰開壓力表旁邊的閥門，將液壓放出，升降機將會自動下降，再進行升降機的損壞原因排查?！父呖兆鳂I(yè)平臺車」液壓控制系統(tǒng)是一個由液壓控制元件

3、 If the elevator stops suddenly during the lifting process, you can unscrew the valve next to the pressure gauge to release the hydraulic pressure, and the elevator will descend automatically, and then check the damage cause of the elevator.
