日常生活中，由于对液压货梯的使用不当，往往会出现升降无力或者是 升不起的现象，下面罗列一下产生这种现象的几种可能性原因：
Daily life, due to the improper use of hydraulic freight elevator, and often appear unable or lift up the phenomenon can not afford to, the following list of what produce several possibilities reasons for this phenomenon:

1.齿轮泵损坏，打出的油无压力，可以通过更换齿轮泵来实现。
1 gear pump is damaged, played no oil pressure can be achieved by replacing the gear pump.

2.手动泵单向阀卡死，回位失灵，解决办法旋开油泵阀口螺栓、检修、 清洗，更换清洁液压油。
2 manual pump check valve stuck, return failure, the solution to unscrew bolts oil valve opening, maintenance, cleaning, replacement of clean hydraulic oil.

3.手动泵、齿轮泵严重漏油，解决办法更换油泵密封圈。
3 hand pumps, gear pumps serious oil spills, the solution to replace the pump seals.

4.滤清器堵塞，解决办法更换或清洗。
4 filter clogging, replacement or cleaning solutions.

5.液压油不足，解决办法加足液压油
5 hydraulic oil shortage, the solution add enough hydraulic oil

6.回油阀未关闭 解决办法旋紧回油阀。
6 oil return valve is not closed solution tighten the oil return valve.

7.支持阀或电磁换向阀动作失灵 A、电磁线圈输入电压不足240V。B、电 磁线圈烧坏C、阀芯卡死。解决办法检修或更换。
7 support action failure valve or solenoid valve A, the electromagnetic coil input voltage less than 240V. B, solenoid coil burned C, valve stuck. Solution repair or replacement.

8.超负荷 每台升降梯都有自己的额定载重量，一旦超载起升，就会出现 起升无力或升不起来的现象，减少载重使其在载重量范围内可解决这个 问题。
8 overload Each has its own lift rated load, once the overload lifting, lifting appears unable or does not rise up phenomenon, reducing the load so that it can solve this problem within the load range.

9.电路断路，解决办法检查按钮接触器及保险丝等。
9.A circuit breaker, the solution is to check the button contacts and fuses.
