EBZ200(A) Rock Tunnel Boring Machine
EBZ200(A) boom-type roadheader is an integrated tunneling machine
with cutting, lading and traveling functions. It is cantilever
longitudinal cutting and part-section type, is used to cutting any
underground section, and is also used in the highway, railway and
water conservancy project.
1.Mixed driven by motor and hydraulic, easy operated, reliable
running
2.Variable stroke pump system to improve the efficiency and reduce
system heat.
3.Inner and outer water spray to reduce the dust.
4.Imported hydraulic components
5.Truncated cone shape 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 arc cutting can be achieved.
6.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.
7.It is with the connecting port for the roof bolters, can drive 2
roof bolters to make supporting.
