Liebherr LTM 1400-6.1 Replaces LTM 1350-6.1 Truck Crane

July 8, 2024
New crane can lift up to 450 tons with a maximum hoist height of 394 feet.

The LTM 1400-6.1 Liebherr truck crane replaces the LTM 1350-6.1. It has a 230-foot telescoping boom and can lift more than the predecessor crane, with a maximum load capacity of 450 tons. Maximum hoist height is 394 feet.

The assembly process for the Y-guying system is different from the predecessor. With just one self-assembly lift, the LTM 1400-6.1 places the guying system on the chassis, where it is then pinned in place. The hydraulic quick coupling closes automatically when the boom is luffed down between the two Y-frames. The electrical connection is established with one final movement and the telescopic boom with Y-guying is ready for use in just a few minutes, according to the company.

Various lattice jibs are available on the Liebherr LTM 1400-6.1. The fixed lattice jib extends the telescopic boom by up to 150 feet and can be mounted at an angle of 0, 10, 20, and 40 degrees. As an option, the fixed jib can be adjusted between 0 and 40 degrees. The luffing lattice jib ranges from 46 to 264 feet.

Total available ballast consists of 100 tonnes of basic ballast and 40 tonnes of additional ballast. The hydraulic ballasting device is integrated in the counterweight frame. The VarioBallast system is fundamentally different to the one found on the predecessor model. The 140 tonnes of total ballast can now be set to a radius of 25 feet to achieve the maximum lifting capacity. In confined spaces, the ballast radius can be reduced to 18 feet.

The crane is powered by the Liebherr single-engine concept and a mechanical drive for the superstructure. The eight-cylinder Liebherr diesel engine has 619 horsepower and 2,267 lb.-ft. of torque.
