Pneumatic Coal Mine Tensioning Tools
Product Detailed

It consists of QYB-0.45/70 Pneumatic Oil Pump and YDC cable tensioner. The pneumatic oil pump feeds power of high-pressure oil t

 

It consists of QYB-0.45/70 Pneumatic Oil Pump and YDC Extend-Retract Jack. The pneumatic oil pump feeds working pressure liquid to the extend-retract jack, and the extend-retract jack bring stress for the bolting cable.  

The Pneumatic Oil Pump is Driven by compressed air with characters of 2 stages increasing pressure, output high pressure oil, largely decrease labor intensity, enhance efficiency.

 The YDC extend-retract jack if fitting for stressing force bolting works in coal mine, tunnels, bridge. With large tensioning power, reliable, well sealed and much durable, it is easy to maintain and operate.
