A crane, in particular a loading crane for a vehicle, comprising - a crane pillar mounted rotatably about a vertical axis, - at least one jib connected to the crane pillar and mounted pivotably about a horizontal axis and at least one jib extension mounted displaceably in the jib, and - at least one piston-cylinder unit for extending and retracting the jib extension relative to the jib, wherein the at least one piston-cylinder unit with its first end engages the jib by way of at least one first force-application region and with its second end engages the at least one jib extension by way of at least one second force-application region, wherein the at least one piston-cylinder unit has a central plane which extends in a viewing direction parallel to the horizontal axis about which the jib is pivotably mounted, and wherein the at least one piston-cylinder unit in a compressive-loaded condition upon extension has a compressive deformation in a direction perpendicularly to the central plane and in a tensile-loaded condition upon retraction has a tensile deformation in a direction opposite to the compressive deformation, characterised in that the at least one piston-cylinder unit with its second end engages the at least one jib extension by way of at least two force-application regions and one of said at least two force-application regions is arranged in displaced relationship with the central plane in the direction opposite to the compressive deformation and the other of said at least two force-application regions is arranged in displaced relationship with the central plane in the direction opposite to the tensile deformation. - a crane pillar mounted rotatably about a vertical axis, - at least one jib connected to the crane pillar and mounted pivotably about a horizontal axis and at least one jib extension mounted displaceably in the jib, and - at least one piston-cylinder unit for extending and retracting the jib extension relative to the jib, wherein the at least one piston-cylinder unit with its first end engages the jib by way of at least one first force-application region and with its second end engages the at least one jib extension by way of at least one second force-application region, wherein the at least one piston-cylinder unit has a central plane which extends in a viewing direction parallel to the horizontal axis about which the jib is pivotably mounted, and wherein the at least one piston-cylinder unit in a compressive-loaded condition upon extension has a compressive deformation in a direction perpendicularly to the central plane and in a tensile-loaded condition upon retraction has a tensile deformation in a direction opposite to the compressive deformation, characterised in that the at least one piston-cylinder unit with its second end engages the at least one jib extension by way of at least two force-application regions and one of said at least two force-application regions is arranged in displaced relationship with the central plane in the direction opposite to the compressive deformation and the other of said at least two force-application regions is arranged in displaced relationship with the central plane in the direction opposite to the tensile deformation.
