Tunnel Heading Machine /Roadheader 

EBZ series type Coal tunnel boring cold heading machine

Tunnel boring machine (TBM); According to the operation mode, it is divided into open tunneling machine and shield tunneling machine.

Working mode: mainly consists of walking mechanism, working mechanism, loading mechanism and transfer mechanism. As the walking mechanism advances, the cutting head in the working mechanism breaks rocks and carries them away. It has the advantages of safety, high efficiency and good quality.

EBZ cantilever tunneling machine is mainly used in coal roadway, semi-coal roadway and soft rock roadway and tunnel tunneling. High configuration, safe and reliable. Through the second transport plane, it can be matched with dump truck, shuttle truck, belt conveyor, etc. to realize continuous cutting, loading and transportation.

1. High configuration, advanced technology, good reliability, low center of gravity and good machine stability; The cutting part is retractable with a retractable stroke of 550mm.

2. The tunnel boring machine has internal and external spray, and the internal spray is the spray behind the teeth, so as to strengthen the external spray and reasonably design the form of external spray. The internal spray has the function of water leakage detection.

3. Large inclination Angle at the bottom of the shovel plate, large ground clearance and strong climbing ability of the whole machine. The motor directly drives the star wheel, which is conducive to loading and bottom cleaning;

4. The horizontal and straight structure of the intermediate transport plane is formed by four-link rod slippage with the shovel plate. When the shovel plate is lifted or horizontal, the length of the scraper chain of the first transport plane changes little;

5. High gantry, smooth transportation, double-chain scraper transport, high-strength wear-resistant steel plate is adopted in the chute to ensure the service life of chute and scraper;

6. The body and rear support are welded with thick plate box structure, with good rigidity and high reliability;

7. The walking drive system is highly integrated with internationally advanced motor and reducer, and the output torque is highly adaptable to the operation of large inclination Angle.

8. The hydraulic system adopts constant power, pressure cutting and load sensitive control;

9. The electric system adopts the new comprehensive protection, with the function of self-diagnosis and memory for the dynamic display of liquid crystal characters.
