Liebherr LTM 1400-6.1 mobile crane
Liebherr presents the world's most powerful 6-axle mobile crane, the Liebherr LTM 1400-6.1
The Liebherr LTM 1400-6.1 is the successor of the successful LTM 1350-6.1. Liebherr's new mobile crane has an outstanding lifting capacity and consists of a 70-meter telescopic boom. It is characterized by simple setup processes and quick operational status.
Liebherr's Ehingen factory updated its product range and launched the world's most powerful 6-axle mobile crane: the new LTM 1400-6.1. The crane has a 70-meter telescopic boom and is characterized by intelligent, simple setup processes. The new mobile crane is the successor of the proven and successful LTM 1350-6.1. Like its predecessor, the LTM 1400-6.1 is the smallest crane with a Y-brace , so it is the perfect introduction to this boom technology due to its huge lifting capacity. The new universal machine is extremely flexible and economical thanks to the wide range of accessories, the highly functional modular boom set and the well-known Liebherr technologies. It also includes driver assistance systems that increase the safety of everyone on the road.
The new Liebherr LTM 1400-6.1 is characterized by high lifting capacity and a 70-meter telescopic boom. Liebherr engineers managed to get the most out of a 6-axle mobile crane during the product development process. The LTM 1400-6.1 achieves a significantly higher lifting capacity than its predecessor, the LTM 1350-6.1 , and is currently the market leader worldwide. By successfully integrating its latest engineering expertise and innovative systems into this mobile crane, Liebherr has created an outstandingly powerful yet easy-to-use machine.
In addition to achieving outstanding performance data, Liebherr also placed great emphasis on simple installation and quick start of work during the development of the new crane. On the construction site, the entire work process leading to the complete operational state is planned as simply as possible. There are significant differences compared to the predecessor model, the LTM 1350-6.1, especially regarding the assembly process of the Y-bracing system. With a single self-assembly lift, the LTM 1400-6.1 places the leveling system on the chassis, where it then snaps into place. The hydraulic quick coupler closes automatically when the boom is placed between the two Y-frames . The electrical connection is made with one final movement, and the Y-braced telescopic boom is ready for use in minutes.
Various truss extensions allow the new mobile crane to work efficiently in a wide range of applications. The fixed lattice boom can extend the telescopic boom up to 45.5 meters and can be mounted at 0°, 10°, 20° and 40° angles . As an option, the fixed boom can be adjusted between 0° and 40°. With lengths ranging from 14 to 80.5 meters, the lattice extension bar provides maximum height, radius and performance.
Additional flexibility thanks to VarioBallast®
Like its predecessor, the new LTM 1400-6.1 consists of a basic counterweight of 100 tons and an additional counterweight of 40 tons . The hydraulic counterweight system is built into the counterweight frame - assembling the counterweight is simple, quick and does not require an auxiliary crane. The VarioBallast® system is fundamentally different from the system found in the predecessor model. The 140-tonne total counterweight can now be adjusted to a massive 7.7m radius to achieve maximum lifting capacity. In closed spaces, the radius of the counterweight can be reduced to 5.6 meters. The counterweight plates are compatible with other large Liebherr mobile cranes, which is a significant advantage for the crane operator both economically and logistically.
The variable VarioBase® support system provides additional versatility. Liebherr's engineers have come up with a new development here as well: in addition to the fact that the predefined support points can be used flexibly with 0%, 25%, 50%, 75% and 100% fixing options, the sliding beams can also be freely expanded between 0% and 50% . Until now, this was only possible on mobile cranes with a maximum of five axes.
Economical thanks to the single-engine concept
Unlike its predecessor, the new 400-ton mobile crane is powered by Liebherr's single-engine concept and the mechanical drive of the superstructure, which results in better economy. The eight-cylinder Liebherr diesel engine with an output of 455 kW / 619 hp and a torque of 3067 Nm provides a powerful travel drive.
Liebherr has developed different driving conditions to ensure worldwide, economical mobility. The LTM 1400-6.1 with an axle load of 12 tons includes a telescopic boom and a detachable hook set, and its total length is 17.8 meters. On the construction site, the 400-ton machine can be driven with a 10-ton counterweight, a three-row hook set and a Y-brace with an axle load of less than 16.5 tons. In the case of roads requiring less axle load, the equipment can be removed.
Driver assistance systems for greater safety
Another innovation is the installation of various driver assistance systems to increase road safety , especially for vulnerable road users such as pedestrians and cyclists. For example, the blind spot information system alerts the crane operator if someone is in the vehicle's blind spot , especially when the crane is turning. The motion detection system gives both a visual and acoustic warning if someone is standing in front of the crane. By monitoring the area around the crane while it is moving, a significant increase in safety can be achieved, despite the presence of components that limit visibility, such as the boom and hook block.
