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

移动式升降平台起升的稳定性相当好，因为设备有四个支腿固定，在我们使用设备前，我们需要将设备的四支支腿打开并且固定好，紧接着我们就可以开始起升作业了。

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.

移动式升降平台年终保养3.液压油的油质和油位。升降机全程升起，在这位置时，液压地面应高出箱底40～50毫米。如发现液压油变暗、发粘或者有砂砾等异物，应及时更换（32#液压油）。

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).

各部位均加注一些润滑油，延长升降机轴承使用寿命。检查液压升降机滚轮、中间轴及轴承，油缸销轴及轴承，臂架铰轴及轴承等有无磨损。

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.

液压系统任何部位之间，卸压，以免压力油喷出，升降机工作台溘然下滑。

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.

升降机一旦过了保修年限，一些维修厂家可能要进行收费，如果是简单的损坏，造成了维修大费用对于客户来说是十分的不划算，因此学习相应的维修知识可以减少不必要的支出。

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、如果升降机突然升不起来，很明显的听到电机空转，这种情况有可能是电机反转了，此时插头两条线进行调转即可，升降机可恢复升降。

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、如果升降机升降不起，也排除了电机反转的原因，但移动式升降平台的各部件正常，没有找到烧毁或碰撞的痕迹，此时，我们可查看移动式升降平台在平台上的制动按钮，如果此制动按钮被按了，升降机是停止状态不能进行任何升降，只需轻轻拨回去即可，升降机可恢复升降状态。

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、如果升降机在升降过程中突发性停止，此时可拧开压力表旁边的阀门，将液压放出，升降机将会自动下降，再进行升降机的损坏原因排查。「高空作业平台车」液压控制系统是一个由液压控制元件

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.
