EBZ220G high-end tunneling machine, with a reasonable overall structural design, low center of gravity, short body, and high stability;
Technical features:
1. The cutting motor has reliable quality and high low-speed torque. The cutting head is optimized using simulation technology, and the cutting teeth are imported brand products with reasonable layout and strong rock breaking ability.
2. The EBZ220G tunneling machine system adopts constant power, pressure cut-off, load sensitive control, and imported pilot control and components.
3. The EBZ220G tunneling machine adopts explosion-proof and intrinsic safety switch box and intrinsic safety operation box; 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.
4. The intermediate transport aircraft is directly driven by imported high flow hydraulic motors, with few potential failure points and strong loading and transportation capacity; The shovel plate shares the same hinge point with the middle transport plane, and during the lifting process, the overlap is smooth, the gap is even, and there is less material leakage.
5. The walking part is driven by a Rexroth hydraulic motor combined with a reducer, which has strong climbing ability; The track adopts a hydraulic cylinder tensioning form, which is convenient, fast, and has low labor intensity.
6. Adopting SKF or FAG imported high-quality bearings, Goetz or equivalent quality floating seals, Parker or Trelleborg seals; Lay wear-resistant plates such as chrome steel at feeding positions such as shovel plates and chutes;
