Heavy Duty Crane Demand
A Liebherr LTM 1400-7.1 mobile crane operated by American company Allegiance Crane worked on the project. The 400-tonner produced an astonishing performance and showed off its wide-ranging functionality.
The LTM 1400-7.1 operated by Allegiance Crane proved to be a good choice, as Michael Stark, owner of Stark Ingenieure and Günter Czasny deputy CEO, reports:
Adam Cote, the Manager of Engineering at Allegiance Crane, and his team were extremely professional on the site. We worked extremely well and closely with each other. And the crane produced an absolutely amazing performance.
It has a compact design and has excellent setup processes coupled with enormous load capacities which meant we didn’t even have to move it between the various hoists. This saved us around half the time which was very important to us.
The LTM 1400-7.1 was equipped with Y-guying and full ballast for this job. The crane set-up was completed entirely by self-assembly. The left wing of the Pegasus was the heaviest single component, weighing in at a massive 58 tonnes. The Liebherr crane had to move this component to a radius of 22.3 metres.
3D-puzzle with 1,250 bronze pieces
The oversized sculpture is an impressive 33 m high and – Pegasus together with the dragon – over 60 m long. In order to realize such magnitude in connection with the organic shape in bronze, seemed an unbelievable, virtually impossible challenge at the beginning for all members of the project management team.
Located in the southwest of Germany, Göppingen based Strassacker art casting foundry, together with the Stark engineering consultancy, from Ludwigsburg, who were commissioned to undertake the costing, calculation and design of the steel structure, developed an implementation concept.
