Big slope expert, hard rock weapon - Sany Heavy EBZ280D TBM

    EBZ280DTBMsIt is a high-power hard rock boring machine with a cutting power of 280kW newly developed by Sany Heavy Equipment, which can be applied to semi-coal rock roadways and full-rock roadways with large slopes, with a maximum rock hardness of F9, a climbing capacity of ± 25°, and a maximum section of 35.75 square meters of roadways.

★ Core Benefits:

1 Strong drive

The whole machine adopts an imported walking reducer with an output torque of 450,000N·m, and the climbing capacity can reach ±25° without relying on any auxiliary devices.

2 The grounding ratio is smaller

The whole machine adopts 850mm wide track, and the ground specific pressure is only 0.15MPa, which can be applied to soft floor roadways.

3 High passability

The approach angle and departure angle of the whole machine reach 13°, and the ground clearance of the fuselage is 350mm, which can be applied to the roadway with large undulating floor floor.

4 Good stability

The width of both sides of the crawler reaches 3.1m, which reduces the vibration caused by the cutting work and ensures the stability of the whole machine.

★Technical features:

Cutting system

· Relying on the cutting head design software independently developed by Sany Heavy Equipment, the picking arrangement, force analysis and cutting effect simulation are automatically determined, so as to achieve the maximum cutting effect and the minimum picking consumption.

Shipping system

· It is driven by a low-speed and high-torque hydraulic motor, and the loading capacity is greatly improved.

· The first transportation channel adopts the flow field design, which effectively solves the problem of transportation stuck materials; The transportation system adopts 14+6 composite wear-resistant plate, which increases the wear-resistant life by 3~5 times.

Walking system

· Equipped with variable walking motor, it realizes low-speed climbing and high-speed walking during tunneling, and improves operation efficiency

· The rear support area is enlarged, which reduces the track resistance and makes the grounding more stable

Hydraulic control system

· The load-sensitive hydraulic system is highly efficient, energy-saving, flexible and comfortable to operate

· The multi-way valve is matched to achieve stepless speed regulation, which is more efficient and more stable to use

Electronic control system

· Real-time monitoring: The electronic control display screen displays the working parameters in real time, and the real-time split screen displays the cutting and post-supporting operation status.

· Intelligent safety: Equipped with expert diagnosis system, voice alarm system and multiple emergency stop control system.
