Tadano America, Houston, Texas, reports the first shipment of its 450-ton flagship ATF 400G-6 all-terrain crane has arrived in North America. The ATF 400G-6 is a six-axle all-terrain that features a powered luffing jib, Tadano’s exclusive Lift Adjuster, Release Adjuster load-sway prevention, power system, and a Mercedes-Benz BlueTec engine.
The five-section boom extends from 49.2 to 196.8 ft under partial load. With the luffing jib, maximum tip height is approximately 400 ft.
The chassis is powered by a Tier 4i-compliant, eight-cylinder Mercedes-Benz OM 502 LA diesel engine with BlueTec, generating 653 hp. According to Tadano, it is the first crane manufacturer to use Mercedes-Benz BlueTec emissions reduction technology across its range as standard.
The 12x8x12 all-wheel steering uses the ZF-Servocom steering system. On the highway, rear-axle steering is speed-dependent. The first and second axles are permanently steered, while axles four and five lock in the straight-ahead position when a speed of 18.6 mph is reached. Axles three and six lock at 31.1 mph.
Key to this crane is the strength of the boom. Highlights of the load chart are the maximum 304,235 lbs. of counterweigh and its ability to lift 83,800 lbs. out to a 46-ft. radius with the boom fully extended. The 196.8-ft. main boom achieves higher capacity than comparable cranes and can lift weights without a guy wire. It can be additionally equipped with the “power system” to further increase the lifting capacity.
The crane is powered by a six-cylinder, 265-hp Mercedes-Benz OM 926 LA engine.
