各式各樣的液壓支腿加固了液壓升降機的穩固性，但是，想要使其發揮更大的作用，就必須在使用支腿時一定要撐穩，平時注意保養。那么當升降機的支腿損壞時應該如何維修呢？

1、維修液壓升降機的支撐系統時先將活動支腿拆下，測量導向槽的尺寸，決定補焊的厚度。
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、補焊時，所示用螺釘和螺母將長方形的紫銅墊安裝好，紫銅管套在螺釘上，補焊完一段，再移動補焊下一段，直至焊完為止。為了方便，也可將焊條適度折彎。這樣做不會影響液壓缸活塞桿的行程和在支腿承重時固定支腿和活動支腿的相對夾角。
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，用一個標準的軸(軸徑等于滾動套的外徑)做基準，進行修形，并應注意其兩邊槽須用同一根軸同時修復。
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.
