A fully radio remote-controlled, rubber-tired surface top hammer drill rig with a vast hole size range (from 38 to 64mm) using R28, R32 and T35 MF-rods, the Commando DC300Ri is equipped with four-wheel drive motors and oscillation, which guarantees excellent mobility and stability in difficult terrain. Together with a new boom structure and a reliable HL300 rock drill, the new rig is said to offer high productivity and low operating costs in challenging environments.
Extremely mobile and agile, the Commando DC300Ri features four powerful tramming motors with maximum tramming force of 43kN. Rubber tyres and ±10 degree oscillation contribute to excellent manoeuvrability. A completely new, re-enforced boom structure with extended swing and reach results in 20% larger coverage area (compared to earlier models) equalling 12m². A flushing air capacity of 3m³/min allows deeper hole depth with larger hole sizes and the 24V electric system ads durability.
The Commando DC300Ri’s intelligent compressor control system and new CAT 3.6 74.4kW Tier4F / Stage5 engine contribute to its claimed unsurpassed fuel efficiency; adding up to more than 30% improvement compared to earlier models in the same size class.
The Commando DC300Ri follows the same novel modular design as other smaller Sandvik next generation surface drill rigs. This logical layout ensures high uptime with easily accessible service points, on-board diagnostics and small transportation dimensions. Being only 2.85m in height allows easy and fast transportation of the rig from site to site on a small truck or even a trailer.
Wide hole range and application specific on-board options make the Commando DC300Ri a multipurpose drill rig. It suits various civil construction works, such as road and railroad job sites, trenching, channelling and different foundation works. The extended reach and the optional hydraulic roll-over, which allows the feed to rotate 360°, make the unit an ideal fit also for dimensional quarry stone drilling and secondary breaking.
The new Commando DC300Ri can be further equipped with several intelligent options to suit specific needs, these include auto-aligning, SanRemo remote monitoring and Remote Screen.
