Swiss company Implenia have rented four Potain top-slewing tower cranes from local dealer Stirnimann for a project in Lausanne, Switzerland.
The real estate and construction services company acquired one Potain MDT 308 and three MDT 389 tower cranes to lift materials for buildings up to 80 metres in height.
Due to the complexities involved at the construction site thanks to its proximity to a railway line, Implenia required a custom-made approach according to Implenia project manager Florian Lamy-Rousseau.
“Several factors make this a complex and unique project with building heights reaching 80 metres and the location of two towers close to the SBB railway,” he said. “For these reasons, we needed a reliable partner in whom we could have total confidence in terms of skills and professionalism.”
“The understanding with Stirnimann employees was the icing on the cake.”
The Swiss company rented the four cranes for the Central Malley project: a new eco-district created to meet environmental challenges and promote energy autonomy. The jobsite specifications of the project include 23,700 metres squared of offices, 200 housing units, and 3,800 metres squared of commercial space.
Potain’s MDT 389 holds a maximum load capacity of 16 tonnes with the crane capable of holding 3.3 tonnes at the end of its 75-metre jib. Alternatively, the MDT 308 possesses a maximum load of 12 tonnes and is able to hold 2.9 tonnes at the end of its 70-metre jib.
“Implenia and Stirnimann have worked hand in hand to meet the project’s diverse requirements,” said Michel Jérôme, technical manager at Stirnimann. “The collaboration in designing and assembling the cranes has been a pleasure.”
The project is set to last for approximately 30 months, with the tower cranes in operation on a daily basis between 7am – 6pm.
