ABSTRACT:
A portable drum dosing system includes an outer mast assembly extending generally horizontally from the main frame and includes a pair of legs disposed at an angle with respect to each other so that the legs may straddle and dispose the main frame near a drum. An upstanding post assembly extends upwardly from the main frame at the outer mast assembly. The post assembly includes a fixed guide post. An upper clamping mechanism is movably mounted to the fixed post for engaging the chime of a drum. A lifting mechanism controls the vertical movement of the upper clamping mechanism and of the stabilizing mechanism to permit a drum to be engaged by the transporter and then lifted and then conveyed from one location to another. An optional weight measuring device is movably mounted to the fixed post to permit the weight of the drum to be accurately determined. A pump mechanism comprising a pump, a dip tube attached to the input side of the pump and a discharge line attached to the output side of the pump is demountably mounted to the clamping mechanism or the drum or moveably mounted to the fixed post or mounted to the main frame. The main frame optionally comprises counter-balance means to minimize a tendency of the transporter to tip during the handling of the drum.
