Coal Mine Cylinders

Hydraulic Drilling Rig

Wide range of applications

Hydraulic drilling rig is widely used in mine drilling, bolting and mesh support, mine exploring. It need to withstand high pollution , face vibration impact, and extremely strong side load; since it is in the underground for a long time,  its maintenance is difficult and the reliability for hydraulic cylinder is very high.


Product Advantages

1.  High-precision displacement sensor built into the cylinder; it can accurately detect the cylinder stroke through digital analog transmission , to ensure the synchronism of combined cylinder;

2.  The innovative copper piling inside inner hole of guide sleeve makes the hydraulic cylinder have higher anti-bias ability;


3.  Based on high frequency quenching, the rod excircle has excellent wear-resistant, anti-collision and anti-corrosion properties through nickel-chromium, multi-layer chromium and other composite electroplating processes.
