Tunnel Construction: Custom Multi-Armed Rig Drills Deep In a brief follow-up to the Atlas Copco Boomer XL3 D featured in ENR’s Nov. 3, 2010, issue, a custom-built Atlas Copco Boomer XE4 C drill rig currently is being used to dig a rail tunnel near Gothenburg, Sweden. Tunneling contractor Veidekke, Oslo, Norway, is employing the fully computerized unit to drill all the pre-grout holes as well as blast holes in the tunnel. The machine’s four booms were equipped with COP 3038 rock drills and feature the new Auto RHS E rod-handling system for drilling up to 30-meter-deep grout holes designed to Veidekke’s specifications. Once programmed, the Boomer XE4 C requires only one operator. Atlas Copco; 413-746-0020;
Wind-Turbine Maintenance: Articulated Aerial Lift TGM Wind Services, Abilene, Texas, recently acquired a third Bronto Skylift Model S-90 HLA—or, high-level articulated—Truck for wind turbine maintenance and repair. The S-90 HLA machine is currently the tallest aerial work platform in use in North America, with a maximum working height of 295 ft. It has a lift capacity of 1,000 lb, with an 8-ft x 3-ft fully enclosed platform. “The platform can be operated by one person, but we recommend having at least one qualified operator on the ground as well,” said Steve Starling, North American sales manager for Bronto, which is expanding its offerings in the U.S. “Electrical utilities were our bread-and-butter for a long time, but wind is a growing market. In Europe, these high-lift trucks are mainly rental, but in the U.S. there is a real preference for ownership of service trucks in wind-turbine servicing.” Bronto Skylift; 352-895-1109;
