Sennebogen presents 50-tonne electric crane
Bavarian construction equipment manufacturer Sennebogen has unveiled the ‘653 E Electro Battery’ telescopic crawler crane at the Bauma trade fair. The 50-tonne model is said to combine “combines the benefits of battery technology with the proven advantages of the telescopic crawler crane design.”
The model is the result of a collaboration with Dutch construction equipment dealer and Sennebogen distributor Van den Heuvel. Dutch crane rental companies and contractors provided input on what model they felt they needed to meet the demands of the “progressive Dutch market,” as Sennebogen puts it. After all, especially in inner-city areas, environmental requirements in Europe are becoming more stringent and will increasingly include construction equipment.
The crawler telescopic crane is based on the existing Sennebogen 653 model, but instead of the diesel engine it has a 130 kW electric motor installed, which is powered by a lithium-ion battery in the superstructure. The 210 kWh battery is liquid-cooled and controlled by an intelligent battery management system. According to the manufacturer, this should allow the crane to last up to 14 hours in battery mode – depending on the type of operation. Sennebogen does not provide details on the components or their suppliers, but the jointly developed solution for the 50-ton crane will be implemented at Van den Heuvel in the Netherlands.
The battery is charged via a 32 A CEE industrial socket, as is usually already available on construction sites. As the onboard charger with 22 kW power has been specifically designed to meet this requirement, no separate charging infrastructure needs to be set up on the construction site – the industrial socket is sufficient.
In addition to quiet and low-vibration operation, Sennebogen highlights lower CO2 emissions and operating costs as advantages in its announcement. “When generating energy from renewable energy sources, the battery-powered crane also saves more than 23 t CO2 per year in single-shift operation,” the company explains. “In addition to the positive CO2 footprint, the machine also has a further significant advantage – it requires less service work, as maintenance procedures such as engine oil changes are completely eliminated.”
Such heavy telescopic cranes are used, for example, to lift, move and position large lifting loads in building construction and bridge building. While the 653 E is the first battery-powered crane in this weight class, it is not Sennebogen’s own: Sennebogen already has two battery-powered handling excavators in its product portfolio in the material handling sector. The new machine will be sold through the company’s usual dealer network.
