各式各样的液压支腿加固了液压升降机的稳固性，但是，想要使其发挥更大的作用，就必须在使用支腿时一定要撑稳，平时注意保养。那么当升降机的支腿损坏时应该如何维修呢？

1、维修液压升降机的支撑系统时先将活动支腿拆下，测量导向槽的尺寸，决定补焊的厚度。
Maintenance of hydraulic lifts leg support system first activity removed, measure the size of the guide groove, the thickness of the welding of the decision.
2、补焊时，所示用螺钉和螺母将长方形的紫铜垫安装好，紫铜管套在螺钉上，补焊完一段，再移动补焊下一段，直至焊完为止。为了方便，也可将焊条适度折弯。这样做不会影响液压缸活塞杆的行程和在支腿承重时固定支腿和活动支腿的相对夹角。
When welding, screws and nuts as shown in rectangular copper pad installed, copper jacket on the screws, finished welding section, under then move some welding until welding last. For convenience,the electrode can also be moderately bent. This does not affect the hydraulic cylinder piston stroke and the relative angle between the fixed leg and activities bearing leg when legs.
3、焊后，用一个标准的轴(轴径等于滚动套的外径)做基准，进行修形，并应注意其两边槽须用同一根轴同时修复。
After welding, using a standard shaft (shaft diameter equal to the outer diameter of the rolling sets) basis, for conduct modification, and should pay attention to the sides of the groove to be repaired with the same shaft at the same time.
