Buckner Companies is using its new Liebherr LR 1600/2 crawler crane to install vessels and components on the A-3 Test Stand at NASA’s John C. Stennis Space Center, Bay St. Louis, Mississippi, USA. Buckner took delivery of the first LR 1600/2 in the USA in October 2009. It is now rigged in SDBW/W configuration. “That is the heaviest lift configuration for the crane, and includes the main boom, the luffing jib with derrick attachment and ballast wagon,” says Jerry Masten, project manager for Buckner Heavylift Cranes, a division of Buckner Companies. The crane is rigged using 197 feet (60 m) of main boom and 118 feet (36 m) of luffing jib. The full complement of boom and jib will reach tip heights of 630 feet (192 m). The ballast wagon is designed for up to 772,000 pounds (350 tonnes). On the main crane the counterweight is designed for up to 331,000 pounds (150 tonnes) and the carbody at 143,300 pounds (65 tonnes). “For maximum lifting capacity you would utilize all of that counterweight,” Masten explains.
