液压货梯http://www.rgsjpt.com/是用液压缸或链条驱动升降的机械设备，主要用于高空作业及高空维修。下面石家庄悦翔机械制造的专家给大家详细分析一下液压货梯压力维持措施有哪些？

1、利用特殊补偿电路
当液压货梯位置或压力下降到一定程度，自动启动补偿系统的作用时，液压货梯回到指定的位置。液压货梯设计补偿系统时，以确保准确性，试验压力，此外还要考虑补偿系统压力，补偿系统压力必须大于系统压力，否则为将发挥的作用与此相反。
When the position or pressure drop to a certain degree, the automatic start compensation system, the hydraulic cargo ladder back to the designated position. Hydraulic cargo ladder design compensation system, to ensure the accuracy of the test pressure, in addition to consider the compensation system pressure, compensation system pressure must be greater than the system pressure, or to play the role of the contrary. 

2、液压换向阀型液压回路或单向液压锁
液压货梯http://www.rgsjpt.com/液压阀的压力效应，液压锁系列单向效果更好，比系列O型液压的压力，但压力效应是仍然有限，目前只使用对于定位精度不高的地方。
The pressure effect of hydraulic valve hydraulic elevator, hydraulic lock series of one-way effect is better than the series O type hydraulic pressure, but the pressure effect is still limited, currently used only for the positioning precision of the place.
