The ATF 400G-6 is a six-axle all terrain (AT) in the 400t capacity class. It is the largest model produced at the Tadano Faun factory in Lauf, near Nuremberg, where all Tadano’s AT cranes are produced.
The new model replaces the ATF 360G-6 that was launched in 2007 and had some success in Japan but less so in Europe due to the weight of the base machine.
The ATF 400G-6 is a wholly new design and much easier to move around between jobsites. The five-section boom extends from 15m to 60m and can telescope even under partial load. With luffing jib, maximum tip height is 124m.
The chassis is powered by a Euromot IIIB compliant Mercedes eight cylinder OM 502 LA diesel engine with Bluetec, generating 480kW (653hp).
Tadano is the first crane manufacturer to use Mercedes Bluetec emissions reduction technology across its range as standard.
The 12x8 steer/drive chassis uses the ZF-Servocom steering system. On highway, first and second axles are permanently steered. Axles 4 and 5 lock in the straight ahead position when a speed of 30km/h is reached. Axles 3 and 6 lock at 50km/h.
The crane upper is powered by a six cylinder Mercedes OM 926 LA engine, rated at 195kW (265hp).
The Japanese manufacturer's proprietary Lift Adjuster technology, that eliminates load sway, is included as standard.
Tadano says that key selling points of the new crane are the strength of the boom and its simplicity in setting up. Load chart highlights, with full 138t counterweight, include the ability to lift 65.4t out to 16m radius and 40.9t out to 26m radius. At 52m radius it can still pick 10.8t using just the main boom, or 12.8t by adding a derricking system.
