The first Potain Hup C 40-30 crawler mounted self-erecting cranes have been deployed on a project in Switzerland.
The cranes will be used to construct a 1.2-kilometre rail flyover at Revens VD station, close to Lausanne.
It will allow trains to pass over existing railway tracks, helping to improve efficiency and convenience for passengers.
Construction equipment supplier Stirnimann AG supplied the Hup C 40-30 cranes for the contractor Implenia. The cranes will work around the clock to complete the flyover by December 2021.
The Hup C 40-30 was launched at bauma 2019 and is the first of Potain’s cranes to be enhanced with crawler tracks for mobility on job sites with challenging terrain.

The crane was developed alongside Stirnimann AG as part of Manitowoc’s Voice of the Customer program.
Stirnimann, based in Olten, Switzerland, was the Hup C 40-30’s first buyer, purchasing six of the unique crawler self-erecting cranes. Half of these cranes are now being used on the Renens VD project.
Implenia selected the cranes due to their ease of transportation, fast and simple erection, and versatility and mobility on a job site.
The crane has a compact transport length of 13.5 metres and a width of 2.55 metres. Equipped with an embedded power generator, it can also travel and erect itself. When folded, the crane can travel 25 metres a minute and featured front levelling up to 30 per cent and side levelling up to 12 per cent.
During the erection process, the crane is hydraulically levelled and has a footprint of 5 metres by 4.5 metres.
“The self-erecting Potain Hup C 40-30 is a truly innovative concept — it’s the first crane to be enhanced with crawler tracks for ultimate mobility,” Stirnimann Managing Director Fritz Oschwald said.
“To build the rail flyover in Renens, Implenia has rented three Hup C 40-30 cranes for ten months. The feedback we have received so far is very positive. Thanks to the mobility of the crane on the job site, our client is able to get to work efficiently and make good progress.”
