Liebherr MK 140 mobile construction crane towers over Mittlerer Ring

A Liebherr MK 140 mobile construction crane has completed a series of lifts on the busy Mittlerer Ring in Munich, Germany.

The Mittlerer Ring – one of the most traffic-heavy roads in Germany – provided a difficult challenge for the construction site to navigate, as the team needed to keep their disruptions to a minimum. For that reason, crane rental company SG-Kran GmbH decided on the MK140 for the job, utilising the crane’s long reach and high jib head load capacity.

Completing the lifts for a multi-storey building to upgrade its air conditioning and heating systems, the 30-kilometre Mittlerer Ring – which provides access to the city’s main routes, with five motorways feeding onto the road – could not be shut down as this would hamper the Munich traffic system.

Furthermore, the practical assembly and dismantling of the crane that can be completed by one person ensured operational time (and therefore traffic restrictions) were kept to a minimum.

Holding a maximum lifting capacity of eight tonnes, the Liebherr MK 140 mobile construction crane is capable of lifting 1.9 tonnes at the end of its jib head, allowing the componentry to be lifted into place easily. Additionally, the five-axle MK 140’s VarioJib concept allows the machine to be operated in either trolley or luffing mode dependent on what the operator needs.

The crane also possesses an “infinitely height-adjustable” elevating cabin to ensure unobstructed views of the load, the construction site, and the surrounding area. Liebherr’s MK 140 is the only machine in the German manufacturer’s range of mobile construction cranes with a three-section telescopic tower of solid wall.
