Abstract
A mobile crane of the type having an upper revolvably mounted on an elongated main frame. The main frame has a central tub for mounting the upper and also has a series of ground-engaging wheels along the main frame and at either side thereof. Power-operated outrigger assemblies are provided for being swingable on the main frame and between the radially outward stabilizing position and a transport, storage position along side the main frame. The outrigger assemblies are elongated and have a rectangular in cross-section shape, one of the axes of the cross-section being greater than the other so as to provide a generally flat in cross-section outrigger. The outriggers can be rotated about their longitudinal axes for about 90.degree. whereby when the outrigger is in the stabilizing position, the major transverse axis is in the vertical direction and when the outrigger is in the storage position, its major axis is in the horizontal position so that the outriggers can be compactly stored above the wheels and along side the main frame of the crane.
