Tadano launch the ATF 600G-8
Last week, Tadano introduced the ATF 600G-8, its largest all-terrain crane to date. The 600-metric-ton, eight-axle crane has a 56-meter telescopic boom with a 90-meter boom extension. Maximum sheave height is 146 meters, and maximum radius is 104 meters.
Tadano remains firm in supporting its two-engine concept, stating it has advantages during crane operation and lowers fuel consumption. The crane uses a 625-hp undercarriage engine and a 354-hp superstructure engine, both supplied by Mercedes-Benz and meet Euromot 4/Tier 4 Final emissions standards.
The ATF 600G-8 incorporates the newly developed Triple-Boom System, which does away with the single main boom and instead consists of three telescoping boom sections connected together with partitions to absorb torsional forces caused by wind or rotary acceleration. “The tubes are farther away from the center of the system’s cross-section, which makes the overall system much more stable than a conventional single telescopic boom system,” according to Tadano. The weight of the Triple-Boom System is similar to a conventional boom, keeping it in line with the 12-ton-per-axle mandatory limit in most countries.
The different telescopes are extended and retracted using a single cylinder system. The way the telescopes are bolted is similar to other Tadano models, according to the company, but the telescopes of the two additional booms are now bolted together consecutively rather than simultaneously (first the power tubes then the telescopes of the main tube).
Benefits of the Triple-Boom System include reduced time and expense associated with transporting, setting up, and operating a boom suspension system or guying system and a tail swing radius of 6.95 meters.
Other key features of the ATF 600G-8 include the asymmetrical outrigger base control, which allows the crane to avoid unnecessary lifting capacity losses caused by a limited outrigger base. Sensors automatically determine the length of all four outriggers and record the position of the superstructure on the basis of the angle of rotation. These figures are sent to the crane control system, which indicates the maximum permissible load for each individual sector of the four outriggers.
With the ATF 600G-8, operators have two new color displays in the superstructure cab. The main display can be operated by touch, keys, or a rotary push button. It shows images from two cameras and can be electronically tilted to adjust to changing light conditions. The other display shows another camera view and can be removed. Operators can decide which display they want to see information on, and they can call up additional information about operating status like average fuel consumption, oil temperature, and hydraulic oil level.
