Function: Essential in long-distance pipe jacking, mainly responsible for relaying the thrust of the main jacking cylinder to overcome soil friction resistance and extend the distance of single pushes. Relay cylinders improve thrust transmission efficiency, maintaining stable propulsion during continuous jacking, accelerating construction progress, and reducing downtime. They also have excellent sealing and pressure resistance, ensuring stable operation under high pressure and enhancing the safety and efficiency of jacking operations.
