Wiesbauer Germany Receives First Spierings Fully Electric Mobile Tower Crane

en.Wedoany.com Reported - On November 12, German crane rental company Wiesbauer received the first SK487-AT3 mobile tower crane produced by Dutch manufacturer Spierings Mobile Cranes. This is the first delivery of this model to the German market. The equipment has a maximum lifting capacity of 7 tonnes and a maximum working radius of 40 metres, at which it can still lift a load of 1.7 tonnes. The equipment features a battery-electric drive system, enabling lifting operations to be completed without the use of an on-site combustion engine.

The handover took place at the Spierings factory in the Netherlands, after which the equipment was delivered to Wiesbauer's company in Bietigheim-Bissingen, Baden-Württemberg, Germany. Wiesbauer is a crane rental company in southern Germany serving the industrial, construction and infrastructure sectors, with a fleet that includes all-terrain cranes, truck cranes, mobile tower cranes, trailer cranes and loader cranes. This acquisition adds fully electric mobile tower cranes to its existing equipment portfolio.

The equipment features a three-axle chassis and a self-erecting tower structure, providing both mobile transport and rapid on-site setup capability. The maximum lifting capacity of 7 tonnes corresponds to a working radius of approximately 12 metres; when the jib is extended to the maximum working radius of 40 metres, the rated capacity is 1,700 kilograms. The equipment offers four tower height configurations of 21 metres, 24 metres, 27 metres and 30 metres, and the jib can be adjusted to luffing angles of 15°, 30° and 45°, with a maximum hook height exceeding 55 metres.

The power system uses a battery-driven solution while retaining a plug-in hybrid operating mode. The equipment can perform travel and lifting operations on battery power, and can also use the onboard small low-emission diesel engine to recharge the battery. In transport configuration, the body is approximately 13.1 metres long, approximately 2.5 metres wide and approximately 4 metres high, with a total machine weight of approximately 36 tonnes. The relatively compact transport dimensions and adjustable outrigger configuration enable the equipment to adapt to space-constrained urban construction sites.

The SK487-AT3 was more than 10 years in development. Spierings first announced the City Boy concept in 2010, but due to the financial crisis, the project did not enter the pre-production and testing phase until late 2017, with the first units delivered in April 2020. Its entry into the German market represents a further expansion of this model in a major European crane rental market.
