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. Side frames retract hydraulically, offering a fully retracted gauge, for transport or work, of 8.4 feet, a mid-range gauge at 11.9 feet and, fully extended, at 14 feet. The TCC-750, designed and built completely in Lexington, Kent., has a four-secion boom with maximum tip height of 121 feet and an optional two-piece lattice fly (with offsets of 2, 15, 30, and 45 degrees) can extend tip height to 179 feet.
