Portable drum dosing system

摘要

A portable drum dosing system (10) includes an outer mast assembly (18) extending generally horizontally from the main frame (12) and includes a pair of legs (20) disposed at an angle with respect to each other so that the legs (20) may straddle and dispose the main frame (12) near a drum (34). An upstanding post assembly (22) extends upwardly from the main frame (12) at the outer mast assembly (18). The post assembly (22) includes a fixed guide post (24). An upper clamping mechanism (30) is movably mounted to the fixed post (24) for engaging the chime of a drum (34). A lifting mechanism (56) controls the vertical movement of the upper clamping mechanism (30) and of the stabilizing mechanism (46) to permit a drum (34) to be engaged by the transporter (10) and then lifted and then conveyed from one location to another. An optional weight measuring device (90) is movably mounted to the fixed post (24) to permit the weight of the drum (34) to be accurately determined. A pump mechanism comprising a pump (96), a dip tube (92) attached to the input side of the pump (96) and a discharge line (94) attached to the output side of the pump (96) is demountably mounted to the clamping mechanism (30) or the drum (34) or moveably mounted to the fixed post (24) or mounted to the main frame (12). The main frame (12) optionally comprises counter-balance means (88) to minimize a tendency of the transporter (10) to tip during the handling of the drum (34).
