ABSTRACT:
A mobile, self-propelled, multicapability apparatus useful for gripping, lifting, moving, rotating, and otherwise manipulating heavy articles. The inventive apparatus comprises: a base structure; a turret rotatably attached to the base structure; a first boom structure having a first end portion pivotably attached to the turret; a second boom structure having a first end portion pivotably connected to the distal end portion of the first boom structure; a first hydraulic assembly for pivoting the first boom structure with respect to the turret; a second hydraulic assembly for pivoting the second boom structure with respect to the first boom structure; a head assembly having a first end portion and a second end portion; and a third hydraulic assembly, connected to the second boom structure and to the first end portion of the head assembly, for pivoting the head assembly with respect to the distal end of the second boom structure. The head assembly used in the inventive apparatus preferably includes a hydraulic rotary actuator for rotating the second end portion of the head assembly with respect to the first end portion of the head assembly.
