90 metre telescopic boom: Weise strengthens its crane fleet with LTM 1300-6.3

Schwerlast Weise GmbH has taken delivery of a new Liebherr LTM 1300-6.3 mobile crane.  www.liebherr.comIn Erfurt, the new LTM 1300-6.3 from Weise proves its worth in its first job assembling a construction crane. The 300-tonne crane strengthens the fleet of the Thuringian crane and logistics company, which will be celebrating its 35th anniversary next year. An important decision criterion was the 6-axle mobile crane's 90-metre telescopic boom, which enables the assembly of construction cranes and electricity pylons without lattice jibs, for example. "With the LTM 1300-6.3, we have opted for a versatile, economical and unrivalled 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 metres. 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." The 90 metre telescopic boom is extended to 69.2 metres. 68 tonnes of ballast are needed to assemble the heaviest part to a radius of 36 metres. 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 metre telescopic boom with an axle load of just 12 tonnes. The record length of 90 metres 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 optimised 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 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 customised 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. Crane handover to three Weise generations in Mörsdorf: (from left to right) Sven Bahms (Liebherr-Werk Ehingen GmbH), Walter Weise-Kahlert, Anja Weise, Roswitha Weise and Hermann Weise, with Klara and Anna Weise in front (all Schwerlast Weise GmbH). 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 metres 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 metres. 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." Hermann Weise founded the company in September 1990, initially as a mobile crane hire company. Construction cranes and lorry loading cranes were added later. Machine transport and industrial removals are now also part of the portfolio. The Weise Group, headquartered at Hermsdorfer Kreuz, currently employs around 60 people. They organise the use of 22 mobile and mobile construction cranes, around 100 construction cranes, eight truck-mounted loader cranes and various other transport units. Hermann Weise explains: "With this fleet, we are well positioned and a competent and reliable partner in our region. We have been working very productively with Liebherr for many years. You could almost describe it as a family relationship. The service is excellent." www.liebherr.com Powered by Induportals Media Publishing
