Coal Boring Machine

It can be applied in various conditions for coal boring, such as solid road, mixed coal-rock, soft rock and so on.

Working Range

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 80mpa and grade is ±18°.

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; the cutting head with two-speed dual-voltage characteristics to adapt to the device much easier to suit different conditions.
