Tadano ATF 400G-6

The Tadano ATF400G-6 represents a major advancement in the 400-tonne all-terrain crane category, developed in 2013 to comply with Japan’s strict road weight regulations while maintaining top-tier lifting performance. Compared to Tadano’s own AR4000M, the ATF400G-6 is 58% lighter without counterweight, making it significantly easier to transport while retaining high-capacity capabilities.

The ATF 400G-6 is offered in two variants. One is a 5-axle configuration with 98 tonnes of counterweight, designed for greater transport efficiency and agility in confined or regulated road conditions. Despite being a 5-axle crane, it competes strongly with 6-axle cranes from other manufacturers in the same class. The other variant features a 138-tonne counterweight, supported by a 6-axle carrier, and is available with an optional 78.5-meter luffing jib and Tadano’s Power System, which enhances setup flexibility and lifting performance.

With the full 138-tonne counterweight, the ATF 400G-6 can lift 65.4 tonnes at a 16-meter radius and 40.9 tonnes at 26 meters. Even at a large 52-meter radius, it can lift 10.8 tonnes using just the main boom. The five-section main boom extends from 15 to 60 meters, offering not only long reach but also partial-load telescoping. When equipped with the luffing jib, the crane reaches a maximum lifting height of 124 meters, making it ideal for tall industrial structures, wind turbine installations, and bridge construction.

One of the standout features of the ATF 400G-6 is its use of Mercedes-Benz BlueTec engine technology, making it the first crane in the industry to standardize this clean diesel system across the Tadano range. The 8-cylinder Mercedes-Benz OM502LA engine on the carrier is Tier 4i compliant, while the superstructure is powered by a 6-cylinder OM926LA engine producing 265 HP, offering strong performance while cutting down fuel consumption and emissions by up to 90% compared to older systems.

The ATF400G-6 is equipped with a variety of exclusive Tadano technologies:

• Lift Adjuster – Automatically corrects for boom deflection, reducing sway during load lifting.
• Release Adjuster – Helps manage load control during lowering operations.
• ZF-Servocom Steering System – Improves vehicle maneuverability and operator comfort.
• Power System – Tadano’s advanced suspension setup for improved ground contact and terrain adaptability.

In terms of milestones, the first ATF 400G-6 unit in Germany was delivered to crane rental company Mayer after its unveiling at CRANE DAYS 2011. Mayer immediately deployed it to a demanding project at the Erdinger Arena ski jump in Oberstdorf, navigating narrow roads and steep inclines to reach the job site. The crane lifted 100-tonne ski jump ramps in tandem with two 220-tonne all terrains, including the ATF 220G-5 from local rental firm Glass Bau.

In the UK, Davies Crane Hire was the first to take delivery of the ATF 400G-6 in June 2013, followed by Barcelona Equipment Inc. (BE) in the US, which supplied the crane for a heavy lifting job with Hammer Haag Steel in Louisiana.

With its powerful lifting capacity, lighter road-ready design, cutting-edge BlueTec diesel technology, and intelligent control systems, the Tadano ATF400G-6 delivers a unique blend of strength, mobility, and environmental responsibility—making it one of the most versatile and advanced cranes in the 400-ton class.
