The team from Kran-Maier, a Landshut-based family-run company, arrived early in the morning to set up the mobile crane in the old town. They completed the assembly of the 12m lattice jib using the latest addition to the crane fleet, a brand new Liebherr LTC 1050-3.1 compact crane.
To ensure that the crane could slew in the alley featuring four-storey town houses, crane operator Martin Auer from Kran-Maier set the 88t of ballast to a reduced radius of 4.78m.
This solution is one of the main benefits of this 250t crane when used in constricted set-up conditions. Thanks to the VarioBase variable support program, which enables each of the supports to be positioned individually, it was even possible to keep a route open for pedestrians to pass.
The supports were extended to around 75% on the side facing away from the load, leaving enough space for passers-by, many of whom took the opportunity to watch the unusual events from as close as possible.
The job required intense concentration. Crane operator Auer had to carefully manoeuvre the main boom on this 250t crane between two gable ends to gain access to the tower sections of the construction crane with the required radius of 40m.
Kran-Maier was founded in 1938 as a truck workshop. It now has a workforce of 25 and relocated to new premises just outside Landshut two years ago. Among other equipment, the company has ten mobile cranes, the most powerful one of which is the Liebherr LTM 1250-5.1.
