During the span of just a few years, the Dino™ DC410Ri top hammer drill rig has become a popular choice for urban contractors and others looking for excellent productivity and mobility in the 51 – 76 mm hole size range. The boom system has the largest coverage area in this drill rig category and the powerful 14-kW RD414 rock drill enables high-capacity drilling. Upgrades were however needed to ensure its proven concept remains competitive for years to come, in terms of both productivity and sustainability.
New engine, wider carrier, carousel and one-hole automation
Several of the key features on the newly-introduced Dino™ DC420Ri have been completely redesigned. A Stage V diesel engine now provides regulatory compatibility for the markets where this low-emission engine standard is required and the rig carrier is wider, offering better stability – thereby improving operator safety in difficult terrain and at challenging work sites. The third major upgrade is the actual drilling system, which can now be fitted with an optional three-rod carousel cassette to enable longer holes, up to a depth of 14 m. Future upgrades will add the option of one-hole automation, making full use of the potentially longer holes and improved productivity made possible by the addition of the drill steel carousel.
Additional upgrades
In addition to the most significant upgrades to the tracked carrier, drilling system and engine, Dino™ DC420Ri will also feature several other smaller, but nevertheless significant, new features. Operators of the new machine will enjoy a new seven-inch touchscreen and a control system and screens with the same look and feel as cabinless Sandvik drill rigs Commando™ DC130Ri and DC300Ri, offering a unified user experience, ease of training and other commonality benefits. The drill navigation system is updated to the TIMi version and the electric systems have been redesigned to improve overall robustness and reliability.
Future upgrades
The development doesn’t stop here. Over the next few years, the Dino™ series will be streamlined into a single Dino™ DC420Ri with two engine options for both Tier 3 and Stage V emission classes. Until then, Dino™ DC410Ri will remain on the market to bridge the offering for those customers who require a Tier 3 engine. Future system updates will also include an open interface for transferring 3D data to third-party systems for purposes such as drilling and blasting planning or production control. Sales of the new Dino™ DC420Ri have already commenced, with deliveries due to start late 2022.
