Construction contractor Fritz Mayer used four Potain tower cranes to help build a new shopping centre in Montabaur, Germany.
The €17.5 million (US$ 19 million) project had a tight schedule of 12 months. To build the 14,000 square metre Westerwald fashion outlet centre, Fritz Mayer used a 10 tonne capacity Potain MDT 218A J10, two 8 tonne capacity MDT 178s and a 6 tonne capacity MDT 128.
The tower cranes were rented from Nauheim-based rental company Hack. Tasks for the towers included lifting on average 22 tonnes of material a day, which increased to 66 tonnes a day at peak times. Most of the units lifted up to five load duty cycles per hour.
To support the cranes on site, reinforced foundations were created. Rigging was achieved with support from Potain riggers.
Mario Engelen, site manager at the Altenkirchen-based company, said, “We work with a wide variety of building materials and often with pre-fabricated components. During the entire construction cycle, crane capacities have to match these tasks and every individual lift process.”
Werner Hack, owner of Hack, added, “From on-time delivery to support with rigging the cranes, Potain in Langenfeld, Manitowoc’s distribution and service facility, has provided excellent service.”
The Westerwald Fashion Outlet is due to open in April 2015.
