Introduction of EBZ260 Underground Piling Equipment Coal Readheader
EBZ260 Underground Piling Equipment Coal Readheader is a boom-type integrated tunneling machine with cutting, lading and traveling functions. It is cantilever longitudinal cutting and part underground section, and is also used in the highway, railway and water conservancy project.
Characteristics of EBZ260 Underground Piling Equipment Coal Readheader
1. Mixed driven by motor and hydraulic, easy operated, reliable running variable stroke pump system to improve the efficiency and reduce system heat.
2. Inner and outer water spray to reduce the dust. Imported hydraulic components.
3. Truncated cone shaps cutting head, big force and reliable layout of cutting picks with good capacity of breaking and getting trough rocks, small vibration, good stability, swivel, rise or downing can be achieved at same time, in this way cutting can be achieved.
4. Separate motor to drive loading and transporting system respectively to reduce the accident rate of loading system during cutting, hence to improve the lading capacity.
5. EBZ260 Underground Piling Equipment Coal Readheader is with the connecting port the roof bolters, can drive roof bolters to make supporting.
