DECEMBER 2015 • E&MJ; 61 www.e-mj.com C R A N E S & R I G G I N G where they are used for maintenance, working on haul trucks, and other tasks. As well as truck-mounted cranes, IMT offers a six-model range of mechanics' trucks, equipped with an integral crane hoist. In September, the company launched a new body design for its Dominator III vehicle, fitted with an IMT model 12000 telescopic crane that provides up to 9.1 m (30 ft) of reach. The new body will be available in both 3.4- and 4.3-m lengths, with the Dominator III designed for midrange lifting needs. Liebherr Lifts High at Antamina In its June 2013 edition (pp. 86–87), E&MJ; reported on the use of three Liebherr AT cranes to lift a 140-mt bucket wheel during a major overhaul on one of the excavators at RWE Power's Hambach lignite mine in Germany. Liebherr has since provided information about one of its crawler cranes, which has been on long-term hire to Joy Global for use at the Antamina copper-zinc mine in Peru. The first of this type in Latin America, the LTR 1220 telescopic crawler crane has a maximum load capacity of 220 mt, and was used for unloading the components of two mining shovels, and then assembling them. Liebherr claims that its hydraulic telescopic boom and crawler gear allowed the crane to handle the most difficult terrain, making it well- suited for this type of work. Benefits include its high load capacity, short setup times, good maneuverability and its ability to travel with a full load. With the mine at an altitude of near 5,000 m, conditions are tough, with extreme temperature fluctuations. Nonethe- less, Liebherr reported that the crane's owner, Gruas Alquileres, has confirmed that the crane has worked effi- ciently and safely, handling the conditions well. Meanwhile, Liebherr's LTM range of mobile cranes runs to no fewer than 21 models, designed for both on- and off-road applications. Capacities range from 35 mt and a maximum lifting height of 44 m for the two-axle LTM 1030-2.1 to IT MEANS: :H·OOKHOS\RXXQGHUVWDQGLI\RXUVFUHHQLVSHUIRUPLQJDWWRSHIÀFLHQF\ with a comprehensive Screen Performance Evaluation. :H·OOSURYLGHDVFUHHQPHGLDVROXWLRQWKDW·VWKHULJKWÀWIRU\RXU needs with our guarantee that it will be more cost-effective than \RXUH[LVWLQJVFUHHQPHGLDDQGSURYLGHHTXDORUEHWWHUHIÀFLHQF\ Our entire company will work to support you.
