"With the LTM 1300-6.3, we have opted for a versatile, economical, and unrivaled fast-erecting crane from Liebherr, and have done so on the background of what is currently a rather negative economic situation in Germany," reports Senior Managing Director Hermann Weise. Son-in-law Walter Weise-Kahlert, who has been working for the company since 2012 and has also been Managing Director since January 2024, adds: "The LTM 1300-6.3 has an extremely long telescopic boom at 90 meters. This has great advantages for the assembly and dismantling of tower cranes and electricity pylons, as we do not have to transport and assemble any folding jibs or lattice extensions on the new 300-tonner. So we save time and money."
Record-breaking boom
Liebherr set a new world record with the launch of the LTM 1300-6.3 around two years ago: never before has a mobile crane been able to carry a 90-meter telescopic boom with an axle load of just 12 tonnes. The record length of 90 meters is achieved by the new LTM 1300-6.3 using an 8-section telescopic boom. That is one section more than similar cranes in this class. Liebherr has optimized the entire steel structure of the crane for lightweight construction in order to be able to carry the complete boom as well as all the sliding beams and a hook block with a 12-tonne axle load on public roads.
The LTM 1300-6.3 is a versatile, economical fast-erecting crane with a peerless telescopic boom length in its class. It features all of Liehberr's latest innovations to ensure safe, powerful crane operations: ECOmode, ECOdrive, VarioBase®Plus, VarioBallast®, Auto-Ballast, single-engine concept, and windspeed load charts. The 300-tonne (360 USt) model will add to the portfolio of Liebherr 6-axle cranes.
The new LTM 1300-6.3 is now the largest mobile crane in Weise's fleet. It replaces an LTM 1250-5.1 there. The assembly of construction cranes will be one of the main tasks of the new 300-tonne crane. Weise itself operates a large fleet of construction cranes. However, the crane will also carry out this work for other tower crane operators. Weise also sees another important area of application in the assembly and dismantling of electricity pylons. These are essential for the energy supply from north to south. Completely new power lines are being built or smaller pylons are being replaced by larger ones. "The versatile customized solutions of the LTM 1300-6.3 naturally also increase the possibilities for exchanging capacity with business partners from our industry," says Walter Weise Kahlert.
Proven prowess in its very first job
Weise sent his new crane directly from the Liebherr manufacturing plant in Ehingen to the first construction site in Erfurt, the state capital of Thuringia. Its task was to erect a construction crane from the company's own fleet. The telescopic boom was extended to 69.2 meters and the slewing platform was equipped with 68 tonnes of ballast in order to assemble the heaviest part weighing ten tonnes at a radius of 36 meters. Walter Weise-Kahlert reports: "The crane operator and our construction crane fitters are very satisfied and impressed with the crane after its first use and are already looking forward to new tasks and projects with this piece of equipment."
In Erfurt, the new LTM 1300-6.3 from Weise proves its worth in its first job assembling a construction crane.
The 90-metre telescopic boom is extended to 69.2 meters. 68 tonnes of ballast are needed to assemble the heaviest part to a radius of 36 meters.
