The new Liebherr LTM 1400-6.1 mobile crane completed its first job in Paris, France, where it dismantled an 80m-high construction crane in restricted working conditions and under tight deadlines.
The crane, operated by Montagrues, utilised its self-assembly Y-guying system, which allowed for rapid deployment on site.
Daniel Pereira managing, director of Montagrues, attended the site in the early hours to observe the first assembly of the new LTM 1400-6.1 mobile crane. He paid particular attention to the self-assembly of the Y-guying system during the operation.
“The new way of assembling the complete Y-guying system, which we call Superlift, really saves us an enormous amount of time,” said Pereira. “And speed is the decisive factor on our construction sites here in Paris.”
Liebherr service technicians supervised the set-up process, which began before sunrise with the correct positioning of the equipment despite the limited available space.
Assembly included the installation of ballast frames and counterweights, followed by the lifting and positioning of the complete Y-guying system onto the undercarriage.
The hydraulic quick coupling mechanism attached the Y-guying system to the telescopic boom, with the crane operator controlling the bolting process. Only the electrical connection required manual completion.
The Solidlink quick coupling technology, adapted from the earthmoving sector, facilitated the fully automatic connection of the Y-guying system and telescopic boom on the LTM 1400-6.1.
For the first time on this model, Solidlink was used to streamline the attachment process, enabling the positioning of 90t of ballast and the installation of the Y-guying system in about two hours.
An additional LTM 1060-3.1 crane assisted by attaching the lattice jib.
STME Grues head Daniel Correia managed the removal of the construction crane alongside Montagrues at the Paris site.
