The largest telescopic-boom crawler crane in Link-Belt’s three-model range, the TCC-1100, has a rated lift capacity of 110 tons and uses a 150-foot, five-section main boom that provides three operator-controlled extend-modes, depending on the operating situation. A range of lattice-type boom attachments can bring tip height to approximately 210 feet. The TCC-1100’s side frames are hydraulically adjustable and provide three track-gauge widths of approximately 9, 13 and 15 feet. Working weight varies with counterweight packages and specific equipment, but nominal working weight is approximately 223,000 pounds. The machine is transported in three or four loads, and the main unit moves at less than 89,000 pounds with side frames removed. Overflow loads are less than 45,000 pounds. Four swing-out jacks lift the main unit on and off the transport trailer and also facilitate side-frame assembly/disassembly. The TCC-1100 uses a 230-horsepower Cummins QSL engine, variable-displacement, piston-type main pumps, and has a maximum line pull off the first layer of 21,120 pounds.
Link-Belt says its 75-ton TCC-750 is the largest telescopic crawler crane that can transport at under 100,000 pounds with tracks attached.
Liebherr’s 1,320-ton (at just over an 8-foot lift radius) LTR 11200 telescopic crawler crane is designed with narrow track width for erecting wind power turbines.
