TADANO MANTIS Corporation will introduce the new model GTC‐1200, 130 US ton, (120t) telescopic boom crawler crane at CONEXPO 2014.
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 GTC‐1200 is the first totally new crane from TADANO MANTIS Corporation since it was acquired by TADANO, LTD in December 2008. The project was managed by the TADANO MANTIS Engineering team but featured collaboration with TADANO LTD and TADANO FAUN Gmbh to utilize the strengths of each group while maintaining TADANO MANTIS’s core competencies. The result represents a step forward in design for TADANO MANTIS ‐ full power, round boom with 2 extension modes, HELLO‐NET 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, 5‐section 42.1 ft – 155 ft (12.8m – 47.2m) 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 complimented with a jib system that includes a 12.5 ft (3.8m) heavy lift jib with a maximum capacity of 44 US ton (39.9t) which is part of the standard bi‐fold jib that has lengths of 33.9 ft / 59 ft (10.3m / 18m). There are also optional 23 ft (7m) lattice insert (max 2) sections. The entire jib system can offset at 0°, 20°, and 40°, and when fully erected, gives a maximum tipheight of 269 ft (82m).
The GTC‐1200 is powered by a Cummins Tier 4f, QSL9 diesel engine rated 350 hp (261 kW) @ 2100 rpm. The load sensing, power controlled hydraulic system optimizes 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 (2.6 km/h) and a maximum unladen gradability of 52%.
