Liebherr MK 140-5.1 Crane Completes Mobile Communications System Replacement in Mannheim
The lift was carried out at a jib radius of 64.2 metres, demonstrating the crane's ability to handle complex lifting operations in confined urban environments. Equipped with VarioJib technology and an electric drive system, the MK 140-5.1 delivered a cost-effective and low-noise lifting solution, making it well suited for work in the city centre.
The Rosengarten Congress Centre, one of Germany's leading conference and event venues, required the replacement of the rooftop mobile communications system on its historic Art Nouveau complex. The project highlights the growing use of electrically powered mobile construction cranes for efficient, sustainable and low-impact operations in urban infrastructure projects.
During the operation, the crane worked luffing job mode. The full counterweight of 13.3 tonnes was utilised. With a reach of 64.2 metres, the mobile communications system was installed precisely and safely. “For this job, I opted for the MK 140-5.1 mobile construction crane. Alternatively, a 350-tonne mobile crane could have been used, but to achieve the required reach, we would have had to fit a luffing jib. This solution would have been considerably more expensive for our client,” explains Florian Schmid, branch manager at SCHOLPP in Mannheim.
High performance with compact dimensions
The MK 140-5.1E is a compact 5-axle crane that achieves performance figures previously reserved for larger crane classes. The crane can be set up in a matter of minutes and is quickly ready for operation. The Vario Jib technology makes it particularly flexible: it allows the crane to be converted from a trolley jib into a luffing jib crane in a short space of time. In luffing jib mode, the MK 140-5.1E achieves a hook height of up to 94.4 metres and a reach of 65 metres with a tip load of 1 tonne.Advantages for use in city centres
In addition to its cost-effectiveness, the mobile construction crane also impressed with its suitability for use in densely built-up urban areas. The crane was powered electrically during the lifting operation. This meant that events in the Rosengarten and in the surrounding hotels could take place without any disruptive noise.Liebherr mobile construction cranes are equipped with fully electric drives and winches for crane operation. This enables low-noise and locally emission-free operation. Furthermore, the vertical telescopic tower and various boom angles facilitate work in the immediate vicinity of buildings. The infinitely height-adjustable crane cab ensures an optimal view of the work area and facilitates precise lifting operations even in confined spaces.
SCHOLPP celebrates a double anniversary
For SCHOLPP, the year 2026 marks two anniversaries: the company is celebrating its 70th anniversary and, at the same time, commemorating the 100th birthday of its founder, Alfred Scholpp. Starting with its first mobile crane in 1956, SCHOLPP has developed into a leading provider of heavy-lift services in south-west Germany. Today, the company employs around 230 staff, operates 80 cranes and has a presence at eight sites.
