Tadano Mantis will exhibit two of its GTC Series cranes October 1-3 at ICUEE 2019, Booth N2002. The popular GTC-800 (88 US tons) will be on display, and the newest addition to the GTC Series — the 50 US ton capacity GTC-500 — will make its trade show debut in Louisville, Kentucky.
The GTC Series of telescopic boom crawler cranes were created for actual job site operating conditions. Market-leading out-of-level load charts allow full-rated capacities on up to 1.5° slopes and strong lifting capabilities up to 4°, eliminating the need for ground preparations to achieve a perfectly level lifting base. Real, useable maximum capacity ratings, pick-andcarry capabilities, and automatic load chart switching for operating slope and track position set the GTC series apart in performance and ease of use. These dynamic machines meet the requirements of our core markets – power transmission, bridge/heavy civil and foundation construction – while expanding the broader appeal of the cranes towards more general lift applications.
The GTC-500 features a 4-section full power boom that allows continuous telescoping with load to the maximum extended length of 113’ 10” (34.7 m). The main boom is complemented with a 28.9ft / 49.9ft (8.8m / 15.2m) bi-fold jib with 5°, 25°, and 45° offsets. An optional Heavy Configuration Counterweight package (28,200 lb /12,791 kg) provides increased lifting performance at longer radiuses.
The GTC-500 has an operating weight of 103,900 lbs (47,128 kg), so it can ship in one standard truckload. The 50-ton machine is powered by a Cummins Tier 4f, Euromot stage IV QSB6.7 diesel engine rated 260 hp (194 kW) @ 2,200 rpm. The GTC-500 boasts a maximum unladen gradeability of 85%, and an unladen ground pressure of 9.3 psi (0.65 kg/cm2). The standard track shoe is a 31.5” (800mm) 3-bar semi-grouser, with optional 35.4” (900mm) wide 3-bar semi-grouser and flat shoe options also available.
At 88 US tons, the GTC-800 is the largest sub-100 ton tele-boom crawler on the market and features a full power, 5-section boom with maximum extended length of 141’ 1” (43.0 m). It is designed for flexibility – performing well for lift work, while also excelling at out-of-level, pick-and-carry, and foundation work. The main boom is complemented by a 33.1ft / 58.1ft (10.1m / 17.7m) bi-fold jib with 3.5°, 25°, and 45° offsets.
The GTC-800 is powered by a Cummins Euromot stage IV, US EPA Tier 4f, QSB6.7 diesel engine rated 231 kW (310 hp) @ 2200 rpm. The travel system features 2-speed track drives with maximum speeds of 2.11 mph (3.4 km/hr) and a maximum unladen gradeability of 78%. The standard track shoe is a 35.4” (900mm) wide 3-bar semi-grouser. Optional 31.5” (800mm) 3-bar semigrouser, plus 35.4” (900mm) and 31.5” (800mm) wide steel flat shoes, are also available.
A new 22,500lb (10,206kg) standard counterweight configuration is being introduced on the GTC-800. Allowing additional flexibility for users, this configuration allows for 2-truck transport while maintaining max rated capacity.
