Small space: The design of light weight and compact disassembled structure make the space occupation smaller which can greatly reduce the impact on road traffic.

 

Visual remote control: In the process of jacking, operator in the operating room can real-time monitor the whole construction process and accurately master the exact cutting speed, travel path and work conditions, etc., which is to realize visualization of remote control.

 

Rock breaking ability: The pipe jacking can break rock hardness up to 300MPa with conical butterfly hob.

 

Eccentric cone crusher: The special design of large eccentric cone crusher can improve the working efficiency with secondary crushing.

 

Stepless speed control: According to various construction conditions, the operator can control the speed of jacking cylinders and the flow of slurry by adjusting the frequency converter, which makes great adaptability and safety.
