Jinan cargo lifter oil installations if there is no return once the hydraulic cylinder will overflow into the excessive, wasteful, but the emergence of a good oil return device to solve this problem, the following day Jinan sharp lifting machinery experts to tell you about Jinan elevating the role of the freight elevator back to the oil installations.

济南升降货梯的安全回油装置在回油机构与油缸之间的回油油路，回油油路上形成有台阶孔。本串联集料升降台内框架、外框架、外框架和内框架在上部和下部分别通过轴承座和导轨板连接在底座和台面架；内框架和外框架以及内框架和外框架分别通过销轴相连接；外框架和外框架以及内框架和内框架分别通过中间销轴相连接；油缸分别连接在内框架和外框架以及内框架和外框架；同步轴上安装有两个连杆，连杆与油缸中间铰接轴相连接。本串联集料升降台结构简单、动作平稳、便于装卸。
Jinan cargo lifter oil installations safe return back to the oil in the return oil path between the institutions and the cylinder, formed with a step on the road back to the oily pores. The series aggregate lifting the platform frame,the outer frame, the outer frame and the inner frame at the upper and lower housings are connected through the guide plate and the base and the table frame; inner frame and outer frame and the inner frame and outer frame by a pin, respectively, connected; the outer frame and an outer frame and within the framework and within the framework of each pin is connected through the middle; cylinder inner frame and outer frame and inner frame and outer frame are connected; synchronous shaft fitted with two connecting rod, connecting rod connected to the cylinder intermediate hinge. The simple structure of the series aggregate lifts, smooth action, easy loading and unloading.

Jinan cargo lifter stepped bore a shaft U-shaped cross-section of the sleeve, the sleeve underside with 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 valve sleeve provided with a control valve.
