Ranger top hammer drilling rig in sandvik

Ranger series has been popular and successful since it was launched in the 1990s. However, even the industry leaders need to make continuous progress and strive for perfection.

"For all kinds of demanding open-pit drilling applications, Ranger drilling rig is a generalist." Jarno Viitaniemi, product manager of Ranger DXi series of mining and rock technology in sandvik, said when outlining the key improvements of the series. "In response to the feedback from quarry operators and contractors, we have specially developed a new series of rock drills for these rigs. We have also increased coverage and improved fuel efficiency. The new cab and advanced automation function help to significantly improve the ergonomic performance, safety performance and production efficiency of the drilling rig. "

The new RANGER DXI series includes Ranger DX800i and Ranger DX900i, the main difference is the engine output power. The smaller Ranger DX800i is equipped with a 185 kW (248 HP) engine, which is ideal for infrastructure and civil engineering. The larger Ranger DX900i has a rated power of 210 kW (282 HP) and is mainly used in large quarries and small mines. In the mining field, pioneering drilling is the most common application occasion, and sometimes it is necessary to carry out production drilling operations.

The new rock drill series makes the Ranger DXi drilling rig with the newly designed design the most powerful drilling rig in this size class, and the impact output power of Ranger DX900i is as high as 27 kW. All rock drills can be upgraded through the CSL system option, which can reduce lubricating oil consumption by up to 300 grams per hour.

The new Ranger DXi drilling rig adopts a brand-new feeding system based on blade chain design, which has the advantages of chain feeding and hydraulic feeding system. The leaf chain will not stretch with long-term use under load, thus extending the maintenance interval.

The new propulsion system also directly improves the production efficiency of the drilling rig, thanks to the redesigned mobile guard, which integrates the functions of annular guide and baffle in a single actuator. This eliminates the lost drilling distance between the guard plate and the ground and increases the drilling distance by 300 mm.
