The Quadstar 1100 is a new 110 US ton (100 tonne) capacity rough terrain crane from Terex Cranes. Highlights include a long boom for its class and a strong load chart, Terex said.
Its 47 metre double keel boom has a dual mode, meaning, in mode 1, lighter sections can be extended first for higher capacity at long radius or, in mode 2, the stronger sections can be used first for higher capacity at shorter radius. Tip height on main boom only is 50 m while the 8 / 16 / 22 m offsettable (at 0, 15 and 30 degrees) jib increases that to a 72 m maximum with two jib sections and a pullout extension.
Power is from a six cylinder, 260 hp Cummins QSB6.7 diesel. The hydraulic system is designed to reduce the number of potential leak points and is easier to service, Terex said. It has three outrigger position settings. Three-mode steering is for better manoeuvrability and the new design cab tilts hydraulically to 18 degrees for better boom tip visibility.
