EBZ75 tunneling machine

EBZ75Introduction to tunneling machine products

EBZ75The tunneling machine is a comprehensive equipment that integrates continuous cutting, loading, transportation, and walking. It is suitable for coal and rock hardness ≤5The excavation of coal or semi coal rock tunnels, as well as soft rock tunnels, involves cutting large amounts of rock with compressive strength up to50MPaThe machine adopts a hybrid transmission mode of electrical and hydraulic, which is easy to operate, reliable, and runs smoothly. The machine is equipped with internal and external spray, which can effectively suppress the dust generated by cutting and improve the working environment.

EBZ75Characteristics of tunneling machine

EBZ75The main characteristics of a tunneling machine are: compact structure, short body, low center of gravity, easy operation, and stable operation. The cutting head is driven by a motor with strong overload capacity. All components are reasonably designed as small component combinations for easy underground transportation and installation. With internal spray, the dust prevention effect is good. The hydraulic system is simple and easy to maintain.

electronic control system

EBZ75The tunneling machine adopts explosion-proof and intrinsic safety switch box and intrinsic safety operation box, which are small in size, light in weight, flexible in operation, and safe and reliable; The main controller is installed in a closed shell, effectively shielding electromagnetic interference; LCD screen display of operating conditions, menu style operation interface, flexible and safe parameter settings; It has functions such as overvoltage, motor overload, phase loss, short circuit, overtemperature, and leakage lockout.

hydraulic system

EBZ75The hydraulic system of the excavator adopts constant power, pressure cut-off, and load sensitive control, and the main hydraulic components are all from world-renowned brands. The cutting head is optimized using simulation technology, arranged reasonably, and has strong rock breaking ability.

Spraying Systems

EBZ75The spray system of the TBM is equipped with internal and external spray, the internal spray is the spray behind the teeth, the external spray is strengthened, the external spray form is reasonably designed, and the internal spray has the function of water leakage detection.

A transport plane

The transport plane adopts a straight structure, which overlaps smoothly with the shovel plate and ensures smooth transportation.

Walking mechanism

The walking drive system adopts highly integrated motors and reducers with world advanced technology, with high output torque and adaptability to large tilt angle operations. If there are weight or total height restrictions during transportation, it can be disassembled for transportation.
