What Are Tunnel Boring Machine Hydraulic Cylinders?
Tunnel boring machine hydraulic cylinders are heavy-duty hydraulic actuators that provide the force and motion required for nearly every major function of a tunnel boring machine (TBM). They are responsible for pushing the machine forward, steering the shield, gripping the tunnel wall, positioning precast concrete segments, adjusting articulated sections, and supporting other hydraulic movements throughout the tunneling process.
Unlike conventional industrial hydraulic cylinders, TBM hydraulic cylinders operate in some of the harshest working environments. Continuous heavy loads, high hydraulic pressure, abrasive rock dust, mud, groundwater, vibration, and around-the-clock operation place exceptional demands on cylinder strength, sealing performance, machining accuracy, and service life.
