A vehicle crane comprising a jib that is raised and lowered by at least one main tensile connector, and a counter jib, where the main tensile connector extends between a first connecting point in the region of a jib head and a second connecting point in the region of a counter jib head. To reduce loading on the jib, in particular during raising and lowering and increase its bearing load overall, the jib has a third connecting point between the first connecting point and its foot opposite the head, and a secondary tensile connector extends between the third connecting point and a fourth connecting point in the region of the head of the counter jib, or the secondary tensile connector extends between the third connecting point via a seventh connecting point on the main tensile connector and a fourth connecting point in the region of the main jib foot.

A lattice mast element for a crane comprises at least two longitudinal elements and at least one transverse element interconnecting the longitudinal elements and at least one bracing element for bracing the lattice mast element by interconnecting the longitudinal elements and/or the transverse element, wherein the longitudinal elements and the transverse element define a load bearing surface of the lattice mast element and the longitudinal elements are each configured as a two-dimensional load bearing structure.
