Abstract: 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.

Abstract: 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.

Abstract: A multi-component lattice mast section comprises a longitudinal axis, a plurality of chord elements extending along the longitudinal axis, a plurality of connection bars interconnecting in each case two adjacent chord elements, a lattice mast cross-sectional surface area with a lattice mast width and a lattice mast height, the lattice mast cross-sectional surface area being oriented perpendicular to the longitudinal axis, and at least two detachably interconnectable lattice mast assemblies, with each of the lattice mast assemblies having a lattice mast assembly width smaller than the lattice mast width and/or a lattice mast assembly height smaller than the lattice mast height, and with the connection bars being firmly connection to a chord element in a working arrangement.

Abstract: A telescopic crane, includes a substructure, a superstructure rotatably mounted onto the substructure, a counterweight and a telescoping boom structure which includes a main boom slewable about a luffing plane. The main boom has a boom base and at least one telescope section received in the boom base and displaceable between retracted and extended positions. At least one guy support is mounted to the boom structure and connected to a guy rope which extends substantially longitudinally in the direction of the boom structure. The guy support is oriented with respect to the luffing plane at an inclination which is so selected that a lateral load acting on the boom structure is partially or entirely received by the guying.

Abstract: A consumable billet for melting and casting a metal matrix composite component is made of a consolidated powder metal matrix composite having a titanium or titanium alloy matrix reinforced with particles. The preferred billet is a blended and sintered powder metal composite billet incorporating titanium carbide or titanium boride into a Ti--6Al--4V alloy.
