XCMG XDN500 FRP GRP Fiberglass Microtunnel Micro tunnelling Pipelay Boring Trenchless Slurry Balance Rock Pipe Jacking Machine
I Performance &Characteristics of XCMG XDN500
1.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.
2.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.
3.Rock breaking ability：The pipe jacking can break rock hardness up to 300MPa with conical butterfly hob.
4.Eccentric cone crusher：The special design of large eccentric cone crusher can improve the working efficiency with secondary crushing.
5.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.
