ABSTRACT:
This invention relates to a drum dolly attachment apparatus having a conventional dolly truck assembly with a drum attachment assembly of this invention connected thereto. The dolly truck assembly includes a main truck frame on a support wheel assembly which is operable to be placed adjacent and under a drum member for connecting thereto. The drum attachment assembly is slidably mounted on an upright vertical handle of the dolly truck assembly and is operable to be placed in contact and grasp a main rim portion of the drum member. The drum attachment assembly is constructed so as to move vertically as required to adjust its position on the main rim portion of the drum member when moved from a vertical to an inclined position. The drum attachment assembly includes a drum connector assembly having a first stationary drum connector connectable to an upper inner portion of the main rim portion and a second actuator drum connector connectable to an outer lower portion of the main rim portion of the drum member. The actuator drum connector is movable against a bias member to a released position and vertically on the support tube of the dolly truck assembly for use in attaching to another drum member for a subsequent grasping, moving, and transporting operation.
