KAIFAN KFM-EBZ220Y ROADHEADER

KaiFan Brand Coal Boring Machine can be applied in various conditions for coal boring, such as solid road, mixed coal-rock.....

A.Working Range

EBZ200H is powerful hard rock tunnel boring heavy machine which has effective driving and powerful cutting function. KaiFan Brand Coal Boring Machine can be applied in various conditions for coal boring, such as solid road, mixed coal-rock, soft rock and so on. It could also work on railway, highway, hydraulic engineering and other tunnels. Its cutting hardness is 100mpa and grade is ±18°.

B.Features

This machine adopts double-quantitative pump, hydraulic control pilot and electronically control valve to ensure the equipment could use in normal and special conditions. Low speed high torque motor effects to reduce the failure rate; shunt valve guarantees synchronism operation of star wheel, first transport and driving motor, meanwhile removing the shunt and reducing the failure rate; driving motor, reducer, brake, brake valve and reducing valve integrate into one compact form which easy to instal; the system uses imported hydraulic components which has low uninstall features, reducing working load and caloric value, delaying the fuel aging, improve fuel working life; centralized lubrication oil ensures the working simplified to the device much easier to suit different conditions.
