Emil Egger AG, a transport and heavy haulage contractor based in Sankt Gallen, Switzerland, recently took delivery of a Liebherr crawler crane LR 11000 from the plant in Ehingen for its first job in Zurich. The 1,000 tonne crane will be in service around six months there for the assembly of large reinforced concrete supports.

This is the first time a Swiss crane contractor operating a crawler crane with a load capacity of 1,000 tonne.
Emil Egger AG received the order to work on a major new construction project in Zurich; a welcome occasion to inaugurate the new unit. The LR 11000 has been booked for around six months with the task of assembling reinforced concrete supports with up to almost 60 tonne and later fa?ade components weighing 90 tonne on the construction site.

A new technical feature lends the crane tremendous advantages for this initial application; the ballast system VarioTray newly developed by Liebherr, a detachable ballast plate for the crane's derrick boom. If the entire counterweight is not required for a lift, a centre section of the suspended ballast weighing up to 160 tonne can be bolted out and used separately. This innovation is ideal for the construction site in Zurich, as the LR 11000 needs to lift supports with weights from 25 to 58 tonne alternately over very small or also very large distances.
