重庆升降机的液压控制系统是整个液压升降货梯运行的关键所在，所以在生产和使用的过程中都要十分的注意。

常见的升降平台液压控制系统在使用时，必须将回油阀旋钮按顺时针方向拧紧，把手动换向阀手柄拉到“中立”的位置，启动电机使系统工作，然后把换向手柄拉到 “起升”的位置，宁波升降平台起升，到达所需高度时，在将换向手柄推到“中立”的位置，液压升降平台停止上升同时要关闭电机，即可作业。
Common Ningbo lifting platform hydraulic control system, when used, must return valve knob clockwise to tighten the manual valve lever pulled a "neutral" position, the starter motor to make the system work, and then reversing lever pull to "lift" position, Ningbo lift platform lift, arrive at the desired height, in the reversing lever pushed to the "neutral" position, hydraulic lifting platform stops rising at the same time want to turn off the motor, then the job.

下降时，松开回油阀，依靠自重就可下降。在液压升降货梯液压控制系统的基础上增加一套备用的手动泵，以备在无电源的情况下使用。使用手动泵时首先将回油阀旋钮按顺时针 方向拧紧，将手柄拉到“中立”的位置，压动手柄液压升降平台便可起升。下降时松开回油阀旋钮液压液压升降货梯靠自重下降，当时用电机或柴油机为动力时操作方法。
When dropped, releasing oil return valve, Ningbo weight lifting platform can rely decline. Add a set of spare hand pump, ready for use in case of no power in the hydraulic control system hydraulic lift freight basis. When using a manual pump first oil return valve knob clockwise to tighten, pull the handle "neutral" position, the movable handle pressure hydraulic lifting platform can lift.Loosen the oil return valve knob hydraulic lift hydraulic freight elevator falls drop by gravity. Method of operation with motor or diesel-powered when the time.
