TunnelMachinery Cylinder
Hydrauliccylinder of tunnel mechanical equipment must withstand high pollution, largeshock vibration and strong lateral load test in special constructionenvironment, and the requirement for reliability of cylinder is higher as it issituated underground for a long time and the maintenance is difficult.
Product Features:
1. Highprecision displacement sensor is built in cylinder, which can accurately detectthe cylinder stroke through the transmission of digital simulation to guaranteesynchronization of the composite cylinder;
2. Theinnovated guide sleeve hole pile copper support technology makes the cylinderhave higher capacity of resistance to partial load;
3. Basedon high frequency quenching, excircle of rod has excellent abrasion resistance,knock against, rust protection performance through nickel chrome, multi-layerchrome and other composite plating process.
Application:
Shieldmachine; push bench; heading machine; drill jumbo
