Import Ebz135 Rock Tunneling Boring Machine — Buy in Bulk from Supplier in China

The EBZ135 Rock Tunneling Boring Machine is a larger cantilever excavator intended for coal and semi‑coal tunnel projects. Its mass is 38 t and its overall envelope measures 9550 mm × 1990 mm × 1550 mm (L × W × H). The power package consists of a 221 kW main motor together with a 75 kW power station and a 135 kW cutting station, delivering robust performance in demanding conditions. Cutter speed reaches 47 rpm and the telescopic extension is 500 mm, enabling precise curve cutting. The unit can tackle rock hardness up to 7 MPa and moves at 0‑9 m/min depending on load.

All hydraulic components are sourced from recognised international manufacturers, mirroring the supplier’s practice of using brands such as Bosch Rexroth and Kawasaki. The cutter features a small conical diameter with a tooth layout that improves breakage efficiency while limiting vibration. An external spray device is fitted to suppress dust during operation. The separate loading system enhances load capacity and stability on uneven ground. Typical hydraulic pressure rating is 25 MPa (standard) and a common cutter material is tungsten carbide (typical).

Major tunnelling contractors and mining enterprises select the EBZ135 for medium‑to‑large tunnel sections where higher power and greater width are required; specific MOQ, pricing and lead‑time details must be obtained directly from the supplier.
