During the construction of a two-storey single-family house in Goch, an intermediate ceiling made of prefabricated reinforced concrete elements was installed with the support of the strongest Böcker truck crane AK 52. The crane of the roofing company Hubert Clees & Sohn GbR lifted the 25 ceiling elements and two wall elements weighing between 350 kg and 2,570 kg in a 4-strand sling chain to their installation place. The required reach was up to 27.5 m. For example, the truck crane transported a 1,850 kg element to a distance of 23 m.
With its large lifting capacity, the AK 52 transported all reinforced concrete elements from the delivering low-loader directly to the installation site without repacking. The optimized handling saved valuable time and manpower, so that all elements were already in place after around five hours. The radio camera on the boom with image transmission to the graphic display of the radio control system provided the crane operator with an optimum view of the working area at all times.
The AK 52 truck crane has supplemented the machinery of the family-owned company from Moers since the fall of 2021. It impresses with its enormous performance data combined with a very compact design and a low slewing radius. Built on Mercedes Arcos, it has a gross vehicle weight of only 32 t and scores with excellent driving and manoeuvring characteristics. As a 4-axle truck, it achieves large extension lengths of up to 52.00 m (optionally 55.00) with a maximum support area of 6.89 x 6.40 m on both sides and lifts payloads of up to 12 t.
