Import Ebz260a B Rock Tunneling Machine — Buy in Bulk from Supplier in China

The EBZ260A B is a boom‑type rock tunnelling machine featuring a mixed motor and hydraulic transmission for reliable operation. It has a curb weight of 82 tonnes and overall dimensions of 11 250 mm × 2 700 mm × 1 900 mm (L × W × H). The engine delivers 470 kW, while the cutting system provides a rated power of 260 kW and cutter speeds of 48 rpm and 24 rpm. The machine can tolerate rock hardness up to 110 MPa, travel at 0‑7.5 m/min, and its 650 mm track shoes generate a ground pressure of 0.16 MPa. Electrical supply is 1 140 V and the design supports tunnel gradients of 18°.

The unit incorporates fully imported hydraulic components and a variable‑pump system that improves energy efficiency. An optional hydraulic anchor‑drill drive can be fitted to enable simultaneous drilling, and a climbing‑assist device allows the machine to negotiate gradients up to 25°. Dust suppression is achieved through an internal spray system, and operation can be performed via hydraulic pilot control or a wireless remote, matching typical industry practice for underground equipment. The separate‑spider load type and reinforced pick bits give the machine a strong breaking capability, while the steel chassis meets standard durability requirements.

The EBZ260A B is intended for large‑scale tunnel projects in highways, railways and water‑conservancy works where high rock hardness is encountered. Primary buyers are civil‑engineering contractors and specialised tunnelling firms that require both cutting power and optional drilling functions. The public data does not list minimum order quantities, pricing or lead‑time; prospective purchasers should contact the supplier to obtain detailed trade terms, packaging options and any certification information.
