The support cylinder of a tunneling machine is a device that is driven by a hydraulic system to support the roadway or working face during the excavation process. Its working principle is mainly based on hydraulic transmission technology, which drives the piston rod to move in and out through the pressure change of hydraulic oil in the oil cylinder, thereby achieving support and fixation of the roadway or working face.

The support oil cylinder of the tunneling machine has the following performance characteristics:

Compact structure and small space occupation: The support cylinder of the tunneling machine is usually made of high-strength materials, with a compact structure that can provide sufficient support in limited space.

Strong support and good stability: driven by the hydraulic system, the support oil cylinder of the excavation machine can provide significant support, ensuring the stability of the excavation machine under complex geological conditions.

Easy to operate and responsive: The operation of the support cylinder of the tunneling machine is usually achieved through hydraulic control valves, which is easy to operate and responsive, and can meet the real-time support needs of the tunneling machine during the excavation process.
