Import Ebz230(A) Rock Tunneling Machine — Buy in Bulk from Supplier in China

The EBZ230(A) is a boom‑type rock tunnelling machine designed for continuous cutting, loading and travelling. It weighs 75 tonnes and measures 11 000 mm × 2 700 mm × 1 885 mm (L × W × H). The main engine delivers 440 kW, while the cutting system provides 230 kW (primary) and 150 kW (secondary) with cutter speeds of 46 rpm and 23 rpm respectively. It can handle rock hardness up to 10 MPa, travel at 0‑7 m/min, and its track shoes are 650 mm wide, producing a ground pressure of 0.137 MPa. The machine operates on a 1 140 V supply and is rated for tunnel gradients of up to 18°.

The unit relies on fully imported hydraulic components from brands such as Bosch Rexroth, Harvey, Parker and Kawasaki, coupled with a variable‑pump hydraulic system that improves efficiency and reduces energy consumption. A built‑in internal and external spray device suppresses dust, and operation can be performed via hydraulic pilot control or an optional wireless remote. The separate‑spider load type and reinforced pick bits give it a high breaking capability, while the steel‑alloy frame meets typical durability standards for underground construction equipment.

The EBZ230(A) is suited to highway, railway and water‑conservancy tunnel projects where continuous rock cutting is required. Primary users are civil‑engineering contractors and specialised tunnelling firms that need a machine capable of both high cutting power and reliable loading.
