Product Features:
The BH27 cantilever tunneling machine is a small multifunctional tunneling machine developed based on the specific mining conditions of small coal mine tunnels in China. It has a modular design, small volume, and is easy to transport and install underground. Adopting a German imported horizontal cutting head, the force is uniform, the operation is smooth, and the service life is long; The hydraulic system adopts an imported load sensitive system, which is efficient, energy-saving, and flexible in operation. Strong work reliability; Imported hydraulic motor for track walking, with strong driving force, suitable for large slopes, and flexible and convenient walking; The hydraulic motor of the star wheel mechanism is directly driven, with high reliability; Efficient spray dedusting and cooling system can effectively reduce and restrain the dust generated by cutting and cool the pick.
