Tadano Mantis has made announcement in 4th March 2016 that they will be introducing the new model GTC-800, an 80 ton (88 US ton) telescopic boom crawler crane at BAUMA Germany 2016. The GTC-800 is CE marked and will be available for global sales in late 2016.
The GTC-800 was the second of the new design for the GTC series telescopic boom crawler cranes which follows the concept to design and build that meets the requirements for its core markets of power transmission, bridge and civil and foundation construction. The crane manufacturer’s also looking into expanding the broader appeal of the crane towards lift crane based markets.
THE GTC-800 design project was a collaboration between Tadano Mantis and Tadano, which the latter aids in building the telescopic boom, integration of Tadano winches, jib, hydraulic cylinders, AML-C and Hello Net telematics.
The full powered, 5-section 11.5m – 43.0m (37′ 8″ – 141′ 1″) hydraulic boom is designed not only to perform for hoisting works, but also capable of out-of-level, pick-and-carry and foundation work. It also can be equipped with a 10.1m / 17.7m (33.1ft / 58.1ft) bi-fold jib that can be offset at 3.5º, 25º and 45º. The maximum lifting height with the jib erected is 60.4m (198ft). An optional 2.5m (8.2 ft) heavy lift jib with a maximum capacity of 21.4t (23.5 US ton) that offset at 3.5º and 30º is also available.
Operating load charts for the GTC-800 are available for gradient up to 4º with automatic out of level load chart switching. Not mentioning that the crane is able to operate with the optimum load charts with Tadano Mantis’ market leading 1.5º slope allowance. The crawler tracks is equipped with width sensors and 3 track width operating zones which the crane has sufficient hydraulic power to either extend or retract on its own and without the need of pinning in position once set to operating width.
The GTC-800 is powered by a Cummins QSB6.7 stage IV, US EPA Tier 4f diesel engine rated at 231 kW (310 hp) @ 2200 rpm. Engine throttle can be controlled in three forms – auto-idle control, adaptive throttle control or foot pedal control. The load sensing, power controlled 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 and a maximum swing speed is 2.0 rpm. The travel system features a 2-speed track drives with maximum speeds of 3.6km/h (2.23 mph) and a maximum unladen gradability of 78%. The standard track show is 900mm wide 3-bar semi-grouser which can be changed with optional 800mm wide steel flat shoe type.
