Abstract: A stacking apparatus of the type which can be connected to a vehicle having a hydraulic system is disclosed comprising a base, a telescope arm support pivotably attached to the base in a manner to allow 360.degree. rotation of the telescoping arm support, and a telescope arm pivotably attached at one end to the telescope arm support in a manner to allow vertical movement of an opposite end of the arm. A load gripping mechanism having at least two gripping plates is attached to the opposite end of the telescope arm. First hydraulic structure are attached to the gripping plates for moving the plates together to grasp an object and for moving the plates apart to release the object and attachment structure are provided for pivotably attaching the support plates to the telescope arm in a manner to permit pivotable movement of the plates in first and second vertical planes which intersect at right angles.
