The concept behind the development of the GTC-1200 was to design and build a telescopic boom crawler crane that met the requirements of the growing Tadano Mantis core markets of power transmission, bridge and civil, and foundation construction while expanding the broader appeal of the crane toward lift crane based markets.
The result represents a step forward in design for Tadano Mantis: a full power, round boom with two extension modes, HELLONET telematics, the Tadano AML-C load moment system, and integration of hydraulic cylinders, winches, and jib systems from the other Tadano Group companies.
The full power, five-section 42.1 ft-155 ft boom was designed to perform well for lift work, while also being capable of out-of-level, pick-and-carry, and foundation work. The main boom is complemented with a jib system that includes a 12.5 ft heavy lift jib with a maximum capacity of 44USt which is part of the standard bi-fold jib that has lengths of 33.9ft/59ft. Up to two optional 23ft lattice insert sections can also be used. The entire jib system can offset at 0°, 20°, and 40°, and, when fully erected, gives a maximum tip height of 269 ft.
The GTC-1200 is powered by a Cummins Tier 4f, QSL9 diesel engine rated 350 hp at 2100 rpm. The load sensing, powercontrolled hydraulic system optimises the hydraulic output to the diesel engine power output for highly efficient operation and control; the swing system is controlled by a separate closed loop hydrostatic transmission for superior swing performance. The travel system features 2-speed track drives with maximum speeds of 1.6 mph and a maximum unladen gradability of 52%.
