TOWNSVILLE CRANES DUAL LIFT KEEP LOCOMOTIVES ON TRACK Working closely with their client Westlink Logistics, Townsville Cranes completed a series of dual lifts involving 70t train locomotives and 16.5t train bodies. TOWNSVILLE CRANES DEPLOYED ITS NEW Tadano Demag AC300-6 300t capacity all terrain and Liebherr LTM 1220-5 220t capacity all terrain for the series of dual lifts. Sam Millar, general manager at Townsville Cranes explains more. “We deployed our new 300T Tadano/ Demag AC300-6 and 220T Liebherr LTM1220-5 for the project which involved a total of three lifts each day.

placing of the locomotive body onto the relevant bogies. Each lift took between 8-9 hours including setup,” said Millar. “For each lift, the 300t capacity AC300-6 was configured with 26.7t of counterweight and the 220t capacity Liebherr with 44t of counterweight. The pick and place radius was at 9 meters for both cranes, and both cranes were boomed up to allow the bogies to be moved into position and then boomed down to land the locomotive onto the bogies,” he said. In terms of percentage of charts both
cranes were lifting at 78 per cent capacity for the dual lift. The Liebherr has a chart of 61t at that radius and counterweight setting and the AC300 has a chart of 60.8t at that radius and counterweight setting. Townsville Cranes supplied all the rigging for the lifts down to the locomotive lifters. The rigging included two custom made spreader bars which are rated at 65t Working Load Limit, says Millar. “The custom-made spreader bars were designed and manufactured in
