Import Ebz160b Rock Tunneling Boring Machine — Buy in Bulk from Supplier in China

The EBZ160B is a cantilever rock tunnelling boring machine designed for coal and semi‑coal tunnel projects. It has an installed weight of 50 t and overall dimensions of 10 400 mm × 2 800 mm × 1 500 mm (L × W × H). Power is supplied by a 280 kW main motor, a 100 kW power station and a 160 kW cutting power unit, while the cutter speed is not disclosed in the source data. Key performance figures include a maximum width of 4 815 mm, capability to cut rock with hardness up to 80 MPa, travelling speed of 0‑7.5 m/min, separate spider voltage of 1 140 V and an applied tunnel gradient of 18 degrees.

The machine incorporates fully imported hydraulic components from brands such as Bosch Rexroth and Parker, and it uses a unique separate‑spider load system that isolates loading from cutting for safety and stability. Typical rock‑tunnelling machines of this class employ a cutter diameter of about 300 mm (typical) and operate under hydraulic pressures near 20 MPa (typical), which matches industry practice for hard‑rock excavation. The compact structure and external dust‑spray device help reduce vibration and improve operator comfort, aligning with standard expectations for underground tunnelling equipment.

EBZ160B is suited to mining contractors and infrastructure firms that require reliable rock breakage in confined tunnels. Buyers should confirm the minimum order quantity, lead‑time and preferred Incoterms directly with the supplier before placing an order. The machine is supplied without a fixed price in the listing; trade negotiations are handled on a case‑by‑case basis. Importers are advised to request certification documents for the hydraulic components and to arrange on‑site testing if required.

He Bei Zhong Xuan Construction Machinery Co., Ltd. is located at Room 2809, Building 2, East International Plaza, No.98 The Yellow River Rd, Hi‑Tech Zone, Shijiazhuang, Hebei 050000, China. The firm is listed in the harbour trust tier on the platform and currently shows a response rate of 0 % with no recorded average response time.

The company operates its own manufacturing base and sources hydraulic components from internationally recognised brands such as Bosch Rexroth, Harvey, Parker and Kawasaki. It markets a range of engineering, mining and hydraulic equipment, including the EBZ160B cantilever tunnelling machine, but the listing does not disclose production capacity, certifications or specific client references.
