32 • ROCK products • September 2015 www.rockproducts.com EQUIPMENT & TECHNOLOGY DRILLING & BLASTING Q uarry and mine drillers now have the advantages of total-site posi- tioning available as standard features in a top-hammer drill rig for line drill- ing and blastholes up to 5 in. in diam- eter. Atlas Copco's fuel-efficient Smar- tROC T45 comes with its own site-nav- igation system. Any drilling company that uses computerized features based on the Global Navigation Satellite Sys- tem can see a benefit. The SmartROC rig's Autofeed Align- ment works with the GNSS to ensure all holes are drilled precisely parallel to each other. GNSS-guided drilling is accurate to within 3.9 in. Perfectly par- allel holes permit wider shot patterns while maintaining control of fracture size, fly-rock and particle velocity. Few- er holes over the same coverage area saves on labor, consumables, rig wear- and-tear and cost of explosives. The SmartROC Progressive Drill Con- trol system adjusts drilling parameters to changes in conditions as formations either gradually change or change sud- denly, as in an encounter with a void. Reduced deviation is gentler on both tooling and the rig. With an engine rated 325 hp at 1,900 rpm and free air delivery of 472 cfm at 175 psi, the SmartROC T45 rig's design efficiency requires only one-third the hoses and cables of other rigs, further reducing maintenance costs, noted Atlas Copco. Extended life of consumables reduces operational costs. The SmartROC T45 is also fuel-efficient, reducing not only fuel costs but time spent interrupting a shift by refueling. Atlas Copco, www.atlas-copco.us Atlas Copco's SmartROC T45 Features Site-Navigation System Sandvik Offers Radio Remote-Controlled Drill Rig Engineered from its conception to com- bine all the best features in one unit – drilling performance with high hole quality, easy maintenance and excel- lent maneuverability, as well as attrac- tive exterior – Sandvik Construction's new Dino DC400Ri is ready to take the lead in surface drilling excellence. The Dino DC400Ri is a hydraulic, self-propelled, self-contained, crawl- er-based surface drilling unit with full radio remote-control operation for 51- to 76-mm hole sizes. It offers top drill- ing performance with a RD414 rock drill, a robust boom, a patented col- laring guide and an economical Tier4 Final engine. Due to its versatility the Dino DC400Ri is the perfect machine for drilling and blasting contractors, but suitable also for quarries and the municipal sector. Its typical applications consist of road construction, demolition works, sec- ondary breaking, foundation drilling and trenching. Representing the latest in technical engi- neering excellence, the Dino DC400Ri combines features significantly improve drilling performance and hole quality. The new, extremely fast RD414 rock drill has been specially designed for the Dino DC400Ri. This provides smooth penetration, yet is kind to the rock tools, while a new patented collaring guide makes starting a hole easy and accurate even in inclined rock. The completely new boom, with a robust design and the largest coverage area in its class, ensures perfect sup- port for the feed during drilling, but also enables more drilling hours from one single setup. On top of this, the powerful tramming motors and low tramming height with its low center of gravity, as well as full radio control for the entire rig, ensure that the Dino DC400Ri will respond with precision even in the most uneven terrain. The Dino DC400Ri comes equipped with the latest fuel saving systems. These consist of electric load-sens- ing, ambient controlled cooler fans, a hydraulic compressor control system that utilizes the latest technology, opti- mized airlines and fuel efficient Tier 4 Final engine. All of these features combine to pro- vide very low fuel consumption. Addi- tionally, easy maintenance through ground level service points, onboard diagnostics and small transportation dimensions are benefits resulting from the completely new drill rig layout.
