First City Boy for Germany

The first all-electric Spierings SK487-AT3 City Boy to arrive in Germany has been delivered to southern German crane rental company Wiesbauer.
The SK487-AT3 can be operated as a full battery electric machine, but can also function as a plug-in hybrid model with a small, low emission diesel engine for topping up.

It has a maximum capacity of seven tonnes - which it can take to a radius of just under 12 metres - and can handle 1,700kg at its maximum radius of 40 metres. Four tower heights of 21, 24, 27 and 30 metres are available, while the jib luffs to 15, 30 or 45 degrees for a maximum lift height of more than 55 metres. Total weight is 36 tonnes, and it has overall stowed dimensions of 13.1 metres long, 2.5 metres wide and four metres high.

The two companies said that the delivery marks an important milestone for both of them. For Spierings, it represents another step in introducing its fully electric crane concept to the German market. For Wiesbauer, the City Boy opens up new possibilities for supporting customers with innovative technology in demanding lifting tasks.

Florian Wiesbauer said:."We want to actively shape the future of our industry. For us, this means not only adopting new technologies but also strategically integrating them into our fleet. The City Boy offers us the opportunity to combine high performance lifting technology with the requirements for lower emissions and quieter operation on site."

"We are delighted that the City Boy has now arrived and that we can put it into practice. Even though the development took longer than originally planned, we always believed in the concept. Now we look forward to gaining experience in real world applications and demonstrating the potential of all-electric lifting technology on German job sites,"

The City Boy was a 10 year plus project for Spierings, it was announced in 2010, but due to the financial crisis did not make it to pre-production & test until late 2017. The first units were finally delivered in April 2020, and it has been fine-tuned in the years since.

Koos Spierings added “We are proud of the City Boy as it stands today, and of all the technical advancements and improvements we have implemented along the way. Innovation requires perseverance and the courage to break new ground. We greatly appreciate that Wiesbauer has maintained its trust in Spierings and our concept throughout this entire process. This makes this first delivery in Germany a special milestone for both companies.”

Based north of Stuttgart in Bietigheim-Bissingen, Wiesbauer runs a fleet of All Terrain, truck mounted, mobile self erectors and trailer cranes as well as loader cranes, for customers working on industrial, construction and infrastructure projects across Baden-Württemberg.
