It is the core power source for driving the pipe jacking process. Its powerful thrust ensures that the pipeline can successfully traverse various complex geological layers. During the jacking operation, the main jacking cylinder not only provides stable pushing force but also precisely controls the extension and retraction speed of the cylinder, enabling smooth and accurate pipe jacking. Additionally, the main jacking cylinder features high pressure resistance and excellent sealing properties, allowing it to work continuously under harsh conditions, ensuring the efficient and safe execution of the pipe jacking construction.
