Liebherr has introduced the LTM 1400-6.1, the most powerful six-axle mobile crane on the market. Unveiled at the recent Customer Days event in Berg-Ehingen, Germany, the 400-tonne crane boasts a 70-metre telescopicboom and features an innovative yet straightforward setup process.
The LTM 1400-6.1 is the successor to the LTM 1350-6.1, offering significantly higher lifting capacities. As the smallest crane equipped with Y-guying, it provides a great introduction to this advanced boom technology. The assembly process for the Y-guying system has been streamlined; with a single self-assembly lift, the system is placed on the chassis and pinned in place. The hydraulic quick coupling automatically closes when the boom is luffed down between the two Y-frames, with the electrical connection established in one final movement. This setup ensures the telescopic boom with Y-guying is ready for use in just minutes.
The crane is equipped with various lattice jibs designed for a wide range of applications. The fixed lattice jib extends the telescopic boom by up to 45.5 metres and can be mounted at angles of 0°, 10°, 20°, and 40°, with an optional adjustment range between 0° and 40°. The luffing lattice jib, ranging from 14 to 80.5 metres, delivers maximum height, radius, and performance.
The LTM 1400-6.1 maintains the 100 tonnes of basic ballast and 40 tonnes of additional ballast found in its predecessor. The hydraulic ballasting device is integrated into the counterweight frame, allowing for fast and straightforward ballast assembly without the need for an auxiliary crane. The new VarioBallast system enables the total ballast to be set to a radius of 7.7 metres for maximum lifting capacity, while in confined spaces, the radius can be reduced to 5.6 metres. The counterweight plates are compatible with those of other large Liebherr cranes.
Liebherr’s variable VarioBase supporting system adds further versatility. Engineers have developed a new feature allowing sliding beams to be freely extended between 0% and 50%, in addition to the predefined support positions with pinning options of 0%, 25%, 50%, 75%, and 100%. This functionality was previously only available on mobile cranes with up to five axles.
Powered by Liebherr’s single-engine concept, the new 400-tonne crane features a mechanical drive for the superstructure, enhancing economy. An eight-cylinder Liebherr diesel engine with 455 kW (619 horsepower) and 3,067 Nm of torque ensures ample drive for travel.
Liebherr has tailored different driving setups to meet global requirements. With an axle load of 12 tonnes, the LTM 1400-6.1, featuring a telescopic boom and detachable hook block, measures an overall length of 17.8 metres. On construction sites, the crane can be driven with 10 tonnes of ballast, a three-line hook block, and Y-guying, with an axle load of under 16.5 tonnes. Equipment can be removed for road journeys that require lower axle loads.
The new crane also includes various driver assistance systems to enhance road safety, especially for vulnerable road users such as pedestrians and cyclists. The Blind Spot Information System warns the driver of individuals in the vehicle’s blind spot, particularly when turning. The moving off information system provides visual and acoustic warnings if someone is in front of the crane. By monitoring the areas around the crane during movement, these systems significantly increase safety despite visibility restrictions caused by components like the boom and hook block.
With the introduction of the LTM 1400-6.1, Liebherr continues to set new standards in mobile crane technology, offering unmatched lifting capacity, innovative design, and enhanced safety features.
