Tunnel Boring Machine Hydraulic Cylinders

A tunnel boring machine hydraulic cylinder is a crucial component of a tunnel boring machine, which is used for excavating tunnels in various types of soil and rock formations. It plays a vital role in the advancement and operation of the tunnel boring machine by providing the necessary thrust and support.

The hydraulic cylinder is a mechanical device that converts fluid power into linear force and motion. In the context of a tunnel boring machine, it is responsible for pushing the cutting head into the ground, applying the required force to break and remove the excavated material, and propelling the tunnel boring machine forward.

Here are some of the different types of tunnel boring machine hydraulic cylinders:

• Thrust cylinders: Thrust cylinders are used to drive the tunnel boring machine forward. They are typically located at the rear of the tunnel boring machine and are attached to the main thrust frame.
• Torque cylinders: Torque cylinders are used to steer the tunnel boring machine through the tunnel. They are typically smaller and less powerful than thrust cylinders.
• Steering cylinders: Steering cylinders are used to control the direction of the tunnel boring machine. They are typically located at the front of the tunnel boring machine and are attached to the cutterhead.
• Support cylinders: Support cylinders are used to support the tunnel face and to prevent the tunnel from collapsing. They are typically located at the front of the tunnel boring machine and are attached to the support ring.
