TBM’s Machines

4. Crossover Machines

Crossover TBMs are versatile tunneling machines designed to seamlessly transition between different tunneling methods, such as Earth Pressure Balance (EPB) and Open Face. These innovative machines are engineered to handle various geological conditions, making them ideal for complex projects that require adaptability. With their advanced technology, Crossover TBMs optimize excavation efficiency while maintaining safety and stability. Discover how these machines enhance tunneling operations by providing flexibility and precision in challenging environments, ensuring successful project completion.

For the most difficult projects, Robbins Crossover TBMs can offer time-saving and efficient tunneling.  Whether the hybrid design converts between EPB and hard rock modes, between Slurry and hard rock, or between EPB and Slurry is up to you.  From heavy duty screw conveyors that handle rock to interchangeable cutting tools, Robbins Crossover TBMs are designed to cross between ground conditions that would typically require multiple machines.

What is a Crossover TBM?

A Crossover TBM (Tunnel Boring Machine) is a specialized type of tunneling equipment designed to handle a variety of geological conditions, including both hard rock and soft ground. The Robbins XRE TBM is a prime example of a Crossover TBM, as it incorporates design elements from both Earth Pressure Balance (EPB) machines and hard rock Single Shield machines.

Crossover Slurry/EPB (XSE) TBMs are cutting-edge tunneling machines designed to tackle a wide range of geological conditions by seamlessly switching between slurry and Earth Pressure Balance (EPB) modes. This versatility allows for efficient excavation in both soft ground and mixed-face environments while maintaining optimal soil pressure to prevent surface settlement. Equipped with advanced technology, XSE TBMs enhance operational efficiency and safety, making them ideal for complex urban tunneling projects. Discover how Crossover Slurry/EPB TBMs revolutionize underground construction by providing flexibility and precision in the most challenging conditions.
