液压升降机阀套内设置了控制阀，升降机还设有回油装置。回油路在回油机构与油缸之间。现在的升降机改为柴油机，电动旋转式两种升降机，还研制了电瓶车载高空作业液压升降平台升降机，它是利用电瓶驱动，升降，无级变速，可以使高空作业者更安全，方便，噪音降低是并环保。
Hydraulic lift valve kit set up control valve lift is also a return to oil installations. Between institutions and return oil back to the oil tanks. Now lift to diesel, electric rotary type two lifts, has also developed a battery-vehicle hydraulic lift aerial work platform lifts, it is the use of battery-driven, lift, variable speed, you can make high-altitude operations more secure, convenient, noise reduction yes and environmentally friendly.
Inside and outside the framework of the hydraulic lifts were all down through the bearing and rail links in the base plate shelves and countertops. Inside and outside the framework related to the pin connected to the fuel tank inside and outside the framework of each link, even a rod installed in the synchronized axis, the middle part of the cylinder rod with a link structure to facilitate handling, smooth operation, easy to operate. Hydraulic lift stepped bore has a cross-sectional U-shaped shaft valve sleeve, the bottom surface of the valve sleeve has a through hole. Formed between the stepped bore and the valve sleeve has a gap, i.e. a gap is formed between the valve sleeve and the stepped bore sidewall the sidewall, the gap may be formed between the bottom of the valve sleeve and the stepped hole bottom, the bottom of the valve sleeve and the stepped bottom of the hole gap can be realized through the creation of lead tank, you can also set up at the bottom of the sleeve to achieve a rough surface, the organizational structure of the lift in the step by step increase, according to the habits and needs of users, technology continues to improve, improve, so will give a lift we bring more convenience.
