Böcker showcased the first fully electric truck crane in steel-aluminum design at bauma 2022. The new electric crane AK 48e does not only work completely electrically in crane and platform mode, mounted on a Mercedes eActros the 27 t carrier also travels to site exclusively battery-powered.

The all-electric crane starts a new era in electric mobility on the construction site. Built on a Mercedes eActros, the 27-tonner travels to site exclusively battery-powered. It also operates purely electrically in crane and platform mode via the E-PTO auxiliary drive. With its quiet drive, it protects residents in built-up areas. Thanks to a powerful battery capacity of 336 kWh, the electric truck crane can cover distances of around 300 km without stopping to charge and reaches any construction site in the wider area.

The range depends on the topography, the driver’s behavior and the outside temperature. The charging time is also impressive. It takes just one hour and 15 minutes to fill the battery from 20 to 80 percent.

Powerful and emission-free at the same time, the AK 48 or AK 48e lifts payloads of up to 3 t (opt. 6 t) and offers extension lengths of up to 49 m (opt. 52). It offers a reach of 15.40 m at 3 t with a lifting height of up to 30 m. As a working platform, the new truck crane is designed for a load of up to 600 kg thanks to its stable mast. The powerful hydraulic system ensures rapid crane erection, a hook speed of 60 m/min and a high working speed.

The mast system, made of high-strength fine-grained structural steel, guarantees great stability, and enables innovative mast geometry. The mast can be erected completely vertically at a 90-degree angle to the vehicle. In addition, the over 14 m hydraulically extendable aluminium jib can erect in a 180-degree position with the joint fully extended.

With the tower crane function, the crane telescopes loads directly into the building thanks to a right-angled jib position. Several variants are available when selecting the drive concept. The new AK 48 is not only available fully electrically, mounted on and driven by an electric truck. It is also available as a diesel truck with PTO drive or in a hybrid version (as diesel plus 400 V electric motor).
