ABSTRACT:
A compact foldable crane for mounting on a truck or the like and of the type including a mast, an inner boom and an outer boom. The mast is made of two sections, a mounting section and an upright section and the two are pivotally interconnected. The upright section is made relatively long in relation to the mounting section and may be lowered on the latter to achieve vertical compactness when the crane is in a stored position. The upright section may also be raised to an upright position to maximize the crane reach when the crane is in an operative position.
