重慶升降機的液壓控制系統是整個液壓升降貨梯運行的關鍵所在，所以在生產和使用的過程中都要十分的注意。

常見的升降平臺液壓控制系統在使用時，必須將回油閥旋鈕按順時針方向擰緊，把手動換向閥手柄拉到“中立”的位置，啟動電機使系統工作，然后把換向手柄拉到 “起升”的位置，寧波升降平臺起升，到達所需高度時，在將換向手柄推到“中立”的位置，液壓升降平臺停止上升同時要關閉電機，即可作業。
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.

下降時，松開回油閥，依靠自重就可下降。在液壓升降貨梯液壓控制系統的基礎上增加一套備用的手動泵，以備在無電源的情況下使用。使用手動泵時首先將回油閥旋鈕按順時針 方向擰緊，將手柄拉到“中立”的位置，壓動手柄液壓升降平臺便可起升。下降時松開回油閥旋鈕液壓液壓升降貨梯靠自重下降，當時用電機或柴油機為動力時操作方法。
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.
