EBZ230 Cantilever Tunnel Boring Machine

    Product Description

    EBZ230 Cantilever Tunnel Boring Machine is widely used in the excavation of medium and large section coal mine roadway, tunnel, water conservancy culvert, etc. It is mainly used for the construction of medium hard rock stratum, soft rock and relatively soft rock. The whole machine has high configuration, good machine stability, strong section adaptability, safety and efficiency.

    The cutting head configuration is rich, and the special cutting head can be selected according to the rock stratum. The standard hard rock cutting head adopts cone design, with reasonable pick layout, strong drilling and rock breaking capacity and low pick loss.

    The surface of the shipping mechanism is made of high-strength wear-resistant steel plate to improve the service life. The double rocker follow-up mechanism is adopted to realize the smooth connection between the front chute of the conveyor and the rear chute of the shovel plate. The driving device is directly driven by hydraulic motor, with strong shipping capacity. The tensioning device adopts the structure of cylinder clamping plate tensioning, which makes the adjustment more convenient.

    The body, rear support and other large structural parts are welded with thick plate box structure, with good rigidity and high reliability.

    The lubrication system adopts centralized lubrication, which makes the regular lubrication more convenient and reliable.

The traveling drive system adopts the motor and reducer of international advanced technology, which is highly integrated and has large output torque. The supporting form adopts the roller type of supporting wheel to improve the walking capacity.

The dust removal spray system adopts annular three layer water curtain dust removal, which has good dust suppression and pick cooling effect.

The hydraulic system adopts constant power, pressure cut-off and load sensitive control, and uses bypass filtration technology to effectively improve the service life of hydraulic components and reduce system faults. The main hydraulic components are international well-known brands.

The electrical system adopts internationally famous brand components with advanced functions and high stability, and has the functions of liquid crystal Chinese character dynamic display, fault self diagnosis and memory.
