Abstract
A material handling apparatus comprises a chassis, an anchoring mechanism retained in the chassis and a material handling mechanism secured to the chassis. The anchoring mechanism provides multi-directional anchoring of the chassis onto a penetrable surface upon which the apparatus rests. The anchoring mechanism comprises a pair of counter-rotating shafts whose lower ends comprise left and right-hand helical augers, respectfully. The upper ends of the shafts are drivingly connected to a means of rotation. The material handling mechanism pulls, pushes or lifts the material being handled. The anchoring mechanism is so retained in the chassis to react the operating forces of the material handling apparatus. Use of this multi-directional anchoring mechanism obviates the requirement for massive, traction based devices, which presently perform large material handling tasks.
