Sandvik Mining and Rock Technology presents two years’ worth of upgrades on the remote-controlled DinoTM DC400Ri surface top hammer drill rig for urban areas and other applications calling for excellent mobility. The upgraded rig, renamed DinoTM DC410Ri, offers significant improvements in electrical and mechanical reliability, 15% higher tramming power and a large number of smaller but nonetheless important updates for improved reliability and productivity.
Dino DC410Ri is a major all-around upgrade from its predecessor Dino DC400Ri, originally launched in 2014. A compact machine for 51 to 76 mm (2 to 3”) hole sizes, Dino DC410Ri continues to offer mobility and stability for contractors tackling cramped urban construction sites, as well as for demanding quarry and infrastructure applications. The remote radio control, 14 kW RD414 rock drill, advanced i-series torque control system and up to 18 square meter (193 sq ft) coverage area add up to a cost-effective and productive solution for demanding jobs.
While retaining the basic design of the original machine, Dino DC410Ri features a number of significant upgrades for improved reliability. Its entirely new electrical system responds to challenges with components such as I/O boards. Several mechanical details have been reinforced, including a steel-framed tramming support for the feed beam and ruggedized rod-handler arms.
The upgraded Dino DC410Ri offers enhanced mobility thanks to 15% higher tramming power compared with the previous model. Other features contributing to excellent mobility include low tramming height, low center of gravity and high ground clearance.
A range of new options available for Dino DC410Ri create even more possibilities to customize the rig for various applications. NoiseShield-DC is a simple and compact noise-reduction solution for Dino DC410Ri, offering up to a −7.5 dB reduction in A-weighted sound pressure within a 16-meter radius of the drill rig. The isolation panels of this patent-pending system are easy and quick to install simply by replacing the standard mesh panels of the safety cage.
Contractors aiming for minimum set-up times can select the feed auto-aligning option, which maintains the alignment of the feed beam at the preset angle even if the position of the boom changes from one hole to the next. Water flushing can be a useful option for applications requiring optimal dust suppression, such as tunneling jobs.
A tangible improvement likely to be appreciated by many operators is the new remote-control unit. It has redesigned joysticks for easier handling with work gloves on, the plastic wiring connectors have been replaced with metallic military-grade components, and the control unit is better protected against moisture leaks in tough, cold environments.
Another practical feature is the possibility to duplicate the drilling control display on an Android phone or tablet. The remote screen, attached to the remote-control unit, gives a perfect view of the drill rig alignment and displays the drilling and tramming parameters for easy and accurate control, even if the rig itself is on the bottom of a deep trench or close to the edge of a hazardous bench.
