Sandvik’s new Commando tackles multiple applications

Sandvik Commando DC300Ri

Sandvik Mining and Rock Technology has released a new Commando series surface top hammer drill rig to its equipment lineup. 

The new Commando DC300Ri is ideal for drill and blast contractors as it suits multiple different construction applications.

The DC300Ri is a modern fully-radio remote-controlled, rubber-tired surface top hammer drill rig with a vast hole size range (from 38 to 64 mm) using R28, R32 and T35 MF-rods. 

The rig is equipped with four-wheel drive motors and oscillation, which enhances mobility and stability in difficult terrain.

Together with a new boom structure and a HL300 rock drill, the new rig combines high productivity and low operating costs in challenging environments, according to Sandvik.

Commando performance

The new Commando DC300Ri features four powerful tramming motors with maximum tramming force of 43 kN in total. Rubber tires and the ±10-degree oscillation also contributes to manoeuvrability.

A completely new, re-enforced boom structure with extended swing and reach results in 20 per cent larger coverage area (compared to earlier models) equalling 12 square metres. 

As well, a flushing air capacity of 3 cubic metres per minute allows deeper hole depth with larger hole sizes and the 24V electric system adds durability.

Featuring the advanced iTorque drilling control system, the Commando DC300Ri delivers top-of-the-line in drilling performance and ensures longer steel life.

The intelligent compressor control system and new CAT 3.6 litre 74.4 kW Tier 4 Final engine contribute to improved fuel efficiency; adding up to more than 30 per cent improvement, when compared to earlier models in the same size class.

The Commando DC300Ri follows the same unique modular design as other smaller Sandvik next generation surface drill rigs. 

The logical layout ensures high uptime with easily accessible service points, on-board diagnostics and small transportation dimensions. Being only 2.85 metres in height allows easy and fast transportation of the rig from site-to-site on a small truck or even a trailer.

Various applications

Wide hole range and application specific on-board options make the Commando DC300Ri a multipurpose drill rig. 

It suits different civil construction works, such as road and railroad job sites, trenching, channelling and different foundation work. The extended reach and the optional hydraulic roll-over, which allows the feed to rotate 360 degrees, also makes the unit an ideal fit for dimensional stone drilling and secondary breaking.

With smaller hole sizes, the Commando DC300Ri suits tunnelling applications perfectly.

The hydraulic roll-over is a necessity in bolting and grouting and the optional one rod adding system gives flexibility and safety.

A special fast tramming option for tunnelling allows the drill rig to keep up with the other fast-moving machines underground. Additional essential options for tunnelling include the exhaust gas purifier (for a Tier 3 engine), water flushing and powerful LED-lights.

In addition, 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
