Finnish engineering group Sandvik has introduced its new hammer drill rig, the Ranger DX900i, representing the top end model of the Ranger DXi series.
The new drill features a 290 degree reach, a powerful rock drill with 21-27 kilowatts of power offering 55 square metres of drill coverage, low cabin noise (measured at 73.5 decibels) and a Volvo 286 horsepower engine, which is more powerful than the DX800i’s 248 horsepower engine.
The low-noise cabin came about as the result of extensive testing with VTT, a Finnish technical research centre, and ensures increased operator comfort during extended use.
The DX900i also has a slightly larger hole diameter than sister product DX800i (89-140mm vs. 64-127mm), which in combination with its higher horsepower makes the new rig well-suited to difficult rock areas. Sandvik calls the DX900i “the most powerful and efficient rig in its class”.
Among the rig’s other features are an iTorque control system and counterweight structure, ensuring maximum operational stability without sacrificing mobility.
