Hydraulics in tunnel construction

Power and precision under extreme conditions

In tunnel construction, high-performance hydraulic systems are crucial to enable tunnel boring machines to advance and to control the complex drilling mechanisms. The hydraulic components are used in Tunnel Boring Machines (TBM), lifting devices and hydraulically controlled transport systems. Hydraulics provide the powerful drive and precise control required to build tunnels in dense layers of rock and under difficult conditions.

Application areas in tunneling

Tunnel Boring Machines (TBM)

Powerful hydraulic cylinders, pumps and valves are used in the highly complex tunnel boring machines to move the cutterhead and control the advance under difficult conditions. The hydraulics enable precise movements, to make tunnel driving safe and efficient.

Lifting devices and lifting systems

Hydraulic lifting devices are used to move heavy machine components and materials in the tunnel. These systems provide the necessary strength and stability to work safely and efficiently in tunnels.

Conveyor technology

Hydraulics are also used for conveyor systems that take over removal of the excavated material. The conveyor belts and vibrating chutes are driven by hydraulic systems to ensure the continuous discharge of the material.

Typical hydraulic components
in tunnel construction

Hydraulic Motors

Hydraulic motors drive rotating parts of the TBM and are responsible for the power transmission in the various machine components. These motors are designed for high performance and a long service life.

Hydraulic Pumps

Axial piston pumps and gear pumps provide the necessary pressure to set the hydraulic cylinders and motors in motion. These pumps are decisive for the energy supply of the TBM and the other hydraulic devices.

Hydraulic Cylinders

Hydraulic cylinders convert the hydraulic energy into linear movements which is essential for moving the cutterhead and other components in the Tunnel Boring Machine.

Hydraulic Valves

These valves regulate the flow of hydraulic fluid and thus control the movements of the machine components. Precise control valves are crucial for coordinating the complex movements involved in tunnel driving.

Advantages of hydraulic systems
in tunnel construction

  • High performance: Hydraulic systems provide the necessary power to work reliably even in demanding tunnel construction projects. They are able to move heavy loads and function under extreme conditions.
  • Precise control: Hydraulic systems enable precise control of the machines, which is particularly important in tunnel construction in order to precisely regulate the advance and movements of the drilling equipment.
  • Reliability under extreme conditions: The robust hydraulic components function reliably even under the most difficult environmental conditions such as high temperatures, high pressure or moisture.
  • Durability and efficiency: Hydraulic systems offer a long service life and ensure that the machines in tunnel construction work efficiently, resulting in shorter construction times and lower costs.
