TADANO MANTIS Corporation introduced the newest addition to the GTC-Series of cranes – the GTC-500 with a 50 US ton capacity (50t @ 2.5m) telescopic boom crawler crane. This latest introduction brings the features and benefits of the GTC-Series to the smaller size class cranes offered by Tadano Mantis.
The GTC-500 is the newest model in the GTC crane series, which follows the concept to design and build a telescopic boom crawler crane that meets the requirements of the growing Tadano Mantis core markets of power transmission, bridge/heavy civil, and foundation construction while expanding the broader appeal of the crane toward lift crane based markets. The GTC-500 is a collaboration between Tadano Mantis and Tadano, Ltd. resulting in a purpose-designed telescopic boom crawler crane. Integration of Tadano winches, jibs, hydraulic cylinders, AML-C, and Hello Net telematics increase reliability and commonality with other Tadano models.
Superior Capacity: The 50 US ton rating is a real, useable capacity with a “level” ground load chart that allows for operation on slopes of up to 1.5° so that the crane can be used to its full capabilities without the requirement of ground preparations to give a perfectly level lifting base. The load charts offer full chart pick-and-carry capacity through 360°. An optional Heavy Configuration (28,200 lbs /12,791 kg) counterweight package provides increased lifting performance at longer radiuses.
Tadano Boom Design: The 4-section full power boom allows continuous telescoping with load to the
maximum extended length of 113’ 10” (34.7 m). The boom is purpose designed for the GTC series crane and
manufactured by Tadano Japan to give high lifting capacities as well as be suited for heavy duty work such as
foundation, pick-and-carry, and work on slopes up to 4°. The main boom is complemented with a 28.9ft / 49.9ft
(8.8m / 15.2m) bi-fold jib that offsets at 5°, 25°, and 45°. The maximum tip height with the jib erected is 170.5 ft
(51.9m). Load charts for jib operation allow for lifting on slopes up to 2.5°.
Dimensions: The GTC-500 has an operating weight of 103,900 lbs (47,128 kg), can ship in one truckload, and
the unladen ground pressure is 9.3 psi (0.65 kg/cm2). The standard configuration of the crane has compact
dimensions of 11’ 5” wide x 42’ 11” length x 12’ 1” working height (with 31.5” wide track shoes) [3.48 m wide x
13.1 m length x 3.69 m working height (with 800 mm wide track shoes)]. Optional 35.4” (900 mm) wide semigrouser
shoes and 35.4” (900 mm) wide steel-flat shoes are also available.
OPTI-WIDTH™: Only Tadano Mantis offers the capability for infinite symmetrical or asymmetrical track
positions on telescopic boom crawler cranes. The powerful hydraulic track extension system on the
undercarriage can adjust the operating width of the crane from 11’ 5” – 17’ 1” (3.48 m – 5.20 m) overall width
(with 31.5” [800 mm] wide track shoes) to provide the optimal lifting base based on site conditions. Tadano
Mantis telescopic boom crawler cranes do not require pinning of the track frames in fixed width positions, so it
is ideal for the crane user to be able to position the track width optimally for their lift work and to have the
proper load charts automatically selected by the AML-C system.
OPTI-WIDTH™ load charts for asymmetrically positioned tracks have significant lifting capacity enhancements
when compared to those for symmetrical track positions. OPTI-WIDTH™ incorporates zoned load charts,
rotational position sensing, and function soft stops to ensure that the crane operator cannot swing with a load
into a zone where the crane will be out of capacity. The crane utilizes the full capabilities of the Tadano AML-C
Rated Capacity Indicator and has operating load charts for 1.5°, 2.5° and 4° slope with automatic out of level
load chart switching based on the cranes position on the jobsite. It is also possible for the operator to set work
zone limits for swing angle, height, and radius, and the crane has function soft stops as operation approaches
these pre-set operating limits.
Efficient Power: The GTC-500 is powered by a Cummins Tier 4f, Euromot stage IV QSB6.7 diesel engine
rated 260 hp (194 kW) @ 2,200 rpm. Engine throttle control is by auto-idle control, adaptive throttle control, or
by foot pedal control. 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, and the maximum swing speed
is 2.0 rpm. The travel system features 2-speed track drives with maximum speeds of 1.8 mph (2.9 km/hr) and a
maximum unladen gradeability of 85%.
Telematics with Hello-Net: Telematics monitors machine work history, position data and maintenance data.
