Hydraulic cylinder for tunnel mechanical equipment must withstand high pollution, large shock vibration and strong lateral load test in special construction environment, and the requirement for reliability of cylinder is higher as it is situated undergound for a long time and the maintenance is difficult.
Product Features:
* High precision displacement sensor is built in cylinder, which can accurately detect the cylinder stroke through the transmission of digital simulation to guarantee synchronization of the composite cylinder;
* The innovated guide sleeve hole pile copper support technology makes the cylinder have higher capacity of resistance to partial load;
* Based on high frequency quenching, excircle of rod has excellent abrasion resistance, knock against, rust protection performance through nickel chrome, multi-layer chrome and other composite plating process.
