1、升降舞臺http://www.qdcbgg.com/電磁換向閥液壓控制系統：按動電動機開關，油泵打油次時油泵處于卸荷狀態，按起動開關，液壓升降機起升。按下降開關，升降舞臺依靠自重下降到原始位置。
Landing stage solenoid valve hydraulic control system: Press the motor switch, buy oil pump oil pump in unloading times, press the start switch, hydraulic lift lifting. Press the down switch, lift the weight down to the stage to rely on the original location.
  
2、升降舞臺液壓控制系統： 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，壓動手柄升降舞臺便可起升，下降時松開回油閥旋鈕升降舞臺靠自重下降。
Landing stage hydraulic control system: increase a spare hand pumps, ready for use in the absence of the power supply situation. When using the hand pump first oil return valve knob clockwise to tighten the landing stage can handle the pressure moving lifting, loosen the oil return valve knob landing stage falls drop by gravity.
  
3、升降舞臺http://www.qdcbgg.com/支撐閥控制液壓系統： 啟動電動機開關，電機旋轉，齒輪泵打油，油缸伸出，升降舞臺起升；待升到工作所需高度時，按電機停止按鈕，升降舞臺停止升降，即可作業，下降時，按電磁鐵接通按鈕，此時油缸回油接通，升降舞臺靠自重下降，帶降到原始位置后，關閉電磁鐵。
Landing stage hydraulic valve control system support: Start the motor switch, motor rotation, gear pumps Dayou, cylinder extends landing stage lifting; when the work needed to be raised to the height of the motor press the stop button to stop the lift landing stage, you can work after, when dropped, the electromagnet on button, then turned back to the oil tanks, landing stage by gravity drop down with the original location, close electromagnet.
