1、升降機廠家http://www.zjfutures.cn/介紹檢查油缸內部有沒有內漏情況，升降是否明顯的下滑，下滑明顯就要看一下油缸，密封圈是否損壞。
Lift manufacturers introduce inspection cylinder internal situation there is no leakage, lifting whether significant decline, we must look at the fuel tank fell significantly, seals for damage.
2、升降機廠家提醒檢查操縱閥、安全閥是否都有損壞，損壞應更換，升降平臺安全閥門若沒有變化，在檢查操縱閥門情況，一般間隙0.06mm，有磨損情況及時更換。
Check control valve lift manufacturers to remind, if the safety valve has damage, damage should be replaced, lifting platform safety valve if there is no change in the manipulation of the valve inspection, the general gap 0.06mm, wear timely replacement.
3、升降機廠家http://www.zjfutures.cn/建議大家一定要測量泵站的壓力，壓力偏低，請進行調整，壓力調不上去，液壓泵站會嚴重損壞。
Lift manufacturer recommends that we must measure the pressure pumping station, low pressure, adjust the pressure transfer does not go up, pump station will be seriously damaged.
