Ebz200 Rock Tunneling Machine

The EBZ200 is a cantilever rock tunnelling machine intended for coal and semi‑coal tunnel applications. Its installed weight is 58 t and the overall footprint measures 10 500 mm × 2 700 mm × 1 840 mm (L × W × H). Power is supplied by a combined 310 kW plus 11 kW motor arrangement, a 110 kW power station and a 200 kW cutting power unit; the cutter speed is not provided in the source data. The machine can reach a maximum width of 5 200 mm, handle rock hardness up to 65 MPa, travel at 0‑10 m/min and features a track shoe width of 650 mm with a ground pressure ratio of 0.135 MPa, while the separate spider voltage is 1 140 V and the tunnel gradient is set at 18 degrees.

All hydraulic components are imported, and the design incorporates a unique separate‑spider load system that improves safety and loading capacity. In the broader market, rock‑tunnelling machines of this size typically use a cutter diameter of around 350 mm (typical) and operate under hydraulic pressures of about 22 MPa (typical), which aligns with the specifications of comparable equipment. The compact structure and external dust‑spray device help reduce vibration and improve operator visibility, matching standard expectations for underground excavation machinery.

The EBZ200 is targeted at mining contractors and infrastructure developers that need reliable rock breakage in confined tunnels. Prospective buyers should confirm the minimum order quantity, lead‑time and preferred Incoterms directly with the supplier, as the listing does not disclose these details. Trade negotiations are handled individually, and importers are encouraged to request certification documents for the imported hydraulic parts and to arrange pre‑delivery testing if required.

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

The supplier maintains its own production facilities and sources hydraulic components from globally recognised manufacturers such as Bosch Rexroth, Harvey, Parker and Kawasaki. Its product portfolio includes a variety of engineering, mining and hydraulic machines, with the EBZ200 representing its larger‑capacity cantilever tunnelling solution. The listing does not provide details on annual output, certifications or specific client projects.
