Green Point Football Stadium
in Cape Town:
In summer 2007 Liebherr-Werk Biberach GmbH supplied twelve brand-new tower cranes for the Green Point Stadium project in Cape Town, South Africa. The delivery included eight top-slewing cranes of types 200 EC H 10 and 280 EC H 12 Litronic, as well as four 200 EC B 10 Litronic Flat-Top cranes. Seven more Liebherr tower cranes in operation at Green Point Stadium, from the EC-H and HC ranges, come from the fleets of the companies Murray & Roberts Construction and WBHO Construction (Pty) Ltd., which make up the Joint-Venture carrying out the construction of the stadium. With an investment volume of 285 million Euros, the old Green Point Stadium, which only had capacity for 18 000 spectators, is being replaced by an entirely new structure in preparation for the 2010 Football World Cup. The overall project also includes improvements to the stadium infrastructure, such as additional parking space, catering areas, VIP sections, and events offices. Green Point Stadium is located in the famous Victoria and Alfred Waterfront district, in a spacious and attractive park. Completion of the conversion and new construction project is scheduled for November 2009. The new arena will provide space for 68 000 football fans. During the Football World Cup in June/July 2010, Green Point Stadium will host five first-round games, one second-round match, and a quarter-final and a semi-final. As well as the World Cup, the stadium will also be used for local football and rugby fixtures, as well as being a venue for large concerts. Liebherr-Werk Biberach GmbH frequently feature in projects of this scale not only as crane suppliers but also as service providers for the engagement project planning of the installed crane park. Liebherr were already providing the know-how gathered over the decades for the 2006 World Cup, skills gained from the project planning of extremely difficult crane operations in numerous stadium construction situations, among others the Allianz-Arena in Munich. For the construction of the Green Point Stadium in Cape Town, Liebherr-Werk Biberach GmbH were again able to offer an economical and complete solution. The equipping and positioning of the twelve new cranes being used in the construction of the stadium was planned as a project in Biberach and the statics carefully calculated. This included the selection of the cranes as well as the ideal individual configuration of each individual equipment unit, with the aim of creating a technically co-ordinated and economically optimised total crane park. The twelve tower cranes supplied by Liebherr are mounted free-standing on foundation anchors, and achieve hook heights of between 52.2 m and 79.5 m. Depending on the projected hook height, the tower systems being used are 256 HC, 290 HC or 500 HC. Four tower cranes from the series EC-H and HC from the existing crane fleet of the Joint-Venture are mounted on rails in the interior of the stadium, so enabling them to cover the construction of the stands in one single large area. Due to the oval shape of the stadium, cranes with differing jib lengths from 55 m to 75 m are being used, with a maximum load capacity of 12 t. The largest crane on the site, a 280 EC H 12 Litronic, can achieve a free-standing hook height of 79,5 m, and offers a maximum capacity of 2800 kg at 75 m working radius. All the new cranes have been supplied in Litronic execution, and accordingly can provide up to 20% more capacity at the push of a button. Integrated in the Litronic crane control system are the LMB load moment limitation system, the ABB work area limitation system. and the MDA machine data evaluation system. As well as this, all the new cranes supplied are equipped with the DFÜ remote data transfer system with Teleservice function, which ensures worldwide dialogue at any time from Customer Service with regard to the current crane operation data. This means that the customer can be supported directly from the manufacturing plant with no time delay at all. Access by means of remote data transfer to the databases of the MDE machine data acquisition system and the MDA machine data evaluation system by Customer Service can be carried out at any time, without the crane having to be stopped or the work sequence interrupted. This means that any problems with the crane can be identified early on and downtimes avoided. Thanks not least to these ultra-modern electronic support resources,
maximum performance values on the site can be absolutely assured.
