In the Swabian town of Untertürkheim, Daimler AG produces engines, axles, transmissions and other components for its Mercedes-Benz Cars division. A new production hall made of precast concrete is being constructed on about 4,500 m² and is scheduled to be finished by April 2015. The Glass Construction Group rented two flexible , one with 300 t and the other with 180 t maximum load capacity, from Wiesbauer GmbH, Bietigheim-Bissingen to securely position the members, which weigh up to 50 t.
The challenge of the construction project was the tight fit of the 10 m deep excavation pit. For optimal logistics, the 300 t crane was positioned in the middle of the construction site. With a pit measuring just 60 m x 75 m, the compact size and simple assembly system of the were pivotal. Together with Wiesbauer GmbH, Glass had already worked out a detailed assembly concept before building began in order to assemble the precast members efficiently and quickly. Preparation that paid off. With the help of the two , the structural work was handed over to Daimler two whole months early.
"The two played an important role," said Michael Stehr, Site Manager at Glass. The simple and space-saving assembly, as well as the ability to travel with load, ultimately tipped the scales in favor of choosing the . While the worked in the pit, its "little brother" helped from outside, as well as with assembling and disassembling the crane in the small pit.
