For the construction of a modern residential property with underground garage at Lake Tegernsee, the construction company Peter Karg is relying on the latest lifting technology from Liebherr. The new Liebherr 43 K serves as the only crane on site and handles all lifting operations, from positioning basement walls and lifting formwork elements to transporting materials for masonry work and the roof structure.
Compact, powerful and intelligent
The 43 K is part of the new K series and combines intelligent assistance systems with impressive performance. With a maximum lifting capacity of 4,000 kg, a 35 metre radius and a hook height of over 30 metres, it offers maximum flexibility on restricted sites. Thanks to its modular design, the crane can be assembled quickly and adapted to changing requirements, a decisive advantage on plots with limited space.
Liebherr’s new assistance systems: Sway Control Plus, Guided Hook, Vertical Line Finder and Positioning Pilot ensure the highest precision in lifting and positioning. Equipped with the latest generation of Liebherr assistance systems, the 43 K provides intelligent features that significantly simplify, accelerate and enhance the safety of crane operation.
The Positioning Pilot enables the crane operator to approach recurring load positions in a partially automated and virtually sway-free manner. This feature was particularly beneficial when placing the heavy precast sandwich basement walls.
“With the assistance systems we were able to position the precast elements with millimetre precision,” explains Peter Karg, owner of the construction company. “The electronic wind release function and the fast, straightforward assembly also fully convinced us.”
In addition, Sway Control provides automatic oscillation damping, ensuring stable lifts even in confined spaces or in disruptive wind conditions. The Vertical Line Finder automatically aligns the rope vertically above the load’s attachment point, preventing side pull and increasing safety on site. Meanwhile, the Guided Hook system makes it easier to guide loads precisely, allowing the hook to be moved effortlessly by a person on the ground.
These systems are supported by a battery-powered IMU sensor integrated into the hook, which continuously records movement data and operates without the need for battery replacement. Together, the assistance systems significantly reduce control effort and contribute to shorter cycle times, noticeable productivity gains and substantial relief for the crane operator.
Technology that convinces
The new-generation 43 K represents a major technological advancement over its predecessor, the 34 K. For the first time, the fast-erecting crane can be operated exclusively in the efficient two-fall mode, eliminating the need for time-consuming reeving. The result: significantly increased hoisting and working speeds across the board.
To ensure maximum precision, efficiency and safety, the 43 K is also equipped with Liebherr’s latest assistance systems, a major advantage over the previous 34 K. “The new systems on the 43 K make our work so much easier. The crane runs smoothly, is extremely precise to control and was ready for use in no time,” Karg adds.
Projects like this demonstrate that the new Liebherr 43 K offers an exceptional combination of performance, compactness and cutting-edge technology.
