[Job Story] First MK 120-5.1E by Liebherr Installs Emergency Roofs in Bern

Swiss company Zaugg AG Rohrbach put the first MK 120-5.1E delivered by Liebherr into operation this summer. At a height of around 20 metres and with a reach of up to 45 metres, the crane positioned temporary roofs over two construction sites in Bern.

“We are using our MK 120-5.1E to lift the parts, which weigh up to 2.5 tonnes, over the houses and place some of them at a maximum distance of 45 metres.”

Explained Stefan Stettler, head of the crane department at Zaugg AG Rohrbach.

The crane, which is equipped with a 400 kW diesel engine, can also rely on site power or adequate mobile 63 Ampere power sources for its lifting work. A mobile Liduro Power Port LPO 100 was available on the construction site in Bern for this purpose. When the battery trailer manufactured by Liebherr is fully charged, the stored energy is sufficient for two days of crane work.

“Low-noise, emission-free crane operations reduce disruption for residents, tourists and passers-by. Only the support on the side away from the site was extended by 50 percent, keeping pedestrian and cyclist access open throughout.”

Explained Stettler.

On a project in Bern, roof structures up to 20 metres long were lifted over existing buildings and chimneys, with some elements even moved across the entire development to an adjacent street. The Liebherr MK 120-5.1E crane handled the tasks with ease, maintaining a lifting capacity of 2.1 tonnes at the tip of its 52-metre boom.
