Abstract: A driving assembly includes a driving device that is slidable along one or more vertical supports as the driving device drives a driving member into an object. The driving assembly may be suspended from a crane or other overhead support, whereby the vertical supports provide balance to the driving assembly and substantially maintain alignment of the driving device with the object. The driving device may slide downward along the vertical supports as the driving device drives against or into the object without requiring adjustment of the overhead support during the driving process. When the driving device has reached a lower portion of the vertical supports, the assembly may be repositioned to position the driving device at the upper end of the vertical supports and the driving process may be repeated. The driving assembly may drive grounding rods into the ground or may break up rock or concrete or the like.
