TL;DR: In this article, a truck slewing crane with a perpendicular slewing axis is used to support a light-duty pickup truck, which is not robust enough to absorb bending moments.
Abstract: A swivel bearing (18) of a truck slewing crane (11) with a perpendicular slewing axis is supported on a truck (10). The crane bridge (20) of the slewing crane (11) runs horizontally and is supported on the base surface by a crane support (21) at the end opposite the swivel bearing (18). Such truck slewing cranes (11) can be used in particular on light trucks, the frames of which are not robust enough to be able to absorb bending moments.
