A drum transporter includes a main frame mounted on wheels with an outer mast assembly extending generally horizontally from the main frame. The outer mast assembly includes a pair of legs disposed at an angle of at least about 90.degree. with respect to each other so that the legs can straddle a pallet and dispose the main frame near a drum on the pallet. An upstanding post assembly extends upwardly from the main frame and includes a fixed guide post with an upper clamping mechanism for releasably engaging a chime of a drum. The upper clamping mechanism is mounted for vertical movement with respect to the fixed guide post. A stabilizing mechanism is also mounted for vertical movement with respect to the fixed guide post for contacting the drum at a location below and remote from the clamping mechanism. A lifting mechanism controls the vertical movement of the clamping mechanism and the stabilizing mechanism. The main frame is counter-balanced to minimize any tendency of the transporter to tip during the handling of a drum.
A self-contained drum transporter comprising a main frame, said main frame having a loading end and a steering end remote from said loading end, a set of wheels mounted to and below said main frame for facilitating the movement of said main frame from one location to another, an outer mast assembly extending generally horizontally from said main frame at said loading end, said outer mast assembly including a pair of legs at said loading end, an upstanding post assembly extending upwardly from said main frame at said outer mast assembly, each of said legs having a longitudinal centerline, extensions of said longitudinal centerlines intersecting generally at said post assembly to form an angle between said legs such that a generally V-shaped spacing between said legs is formed at said loading end, said angle being about 90.degree. with respect to said legs to permit said legs to straddle and be disposed generally against a perpendicular corner of a pallet and to dispose said main frame near a drum to be selectively transported on and off the pallet, said post assembly including a fixed guide post, an upper clamping mechanism for releasably engaging the chime of a drum, said upper clamping mechanism being movably mounted to said fixed guide post and being disposed in said spacing between said legs for selective vertical movement up and down with respect to said fixed guide post, a stabilizing mechanism for contacting the drum at a location below and remote from said upper clamping mechanism, said stabilizing mechanism being movably mounted to said fixed guide post and being disposed in said spacing between said legs for selective vertical movement up and down with respect to said fixed guide post, said spacing being free of any structure outwardly of said upper clamping mechanism and said stabilizing mechanism, the length of said main frame from said steering end to the loading end side of said guide post being longer than the distance said legs extend outwardly from said loading end side of said guide post, said legs being adjustable in length, a lifting mechanism selectively controlling the vertical movement of said upper clamping mechanism and of said stabilizing mechanism to thereby permit a drum on a pallet to be engaged by said transporter and then be conveyed from one location to another, said main frame having a compartment at said steering end with said post assembly being between said compartment and said outer mast assembly, and said main frame comprising counterbalance means including weights in said compartment to minimize any tendency of said transporter to tip during the handling of a drum.
A self-contained drum transporter comprising a main frame, a set of wheels mounted to and below said main frame for facilitating the movement of said main frame from one location to another, an outer mast assembly extending generally horizontally from said main frame, said outer mast assembly including a pair of legs, said legs being disposed at an angle of at least about 90.degree. with respect to each other to permit said legs to straddle a pallet and dispose said main frame near a drum to be transported, an upstanding post assembly extending upwardly from said main frame at said outer mast assembly, said post assembly including a fixed guide post, an upper clamping mechanism for releasably engaging the chime of a drum, said upper clamping mechanism being movably mounted to said fixed guide post for selective vertical movement up and down with respect to said fixed guide post, a stabilizing mechanism for contacting the drum at a location below and remote from said upper clamping mechanism, said stabilizing mechanism being movably mounted to said fixed guide post for selective vertical movement up and down with respect to said fixed guide post, a lifting mechanism selectively controlling the vertical movement of said upper clamping mechanism and of said stabilizing mechanism to thereby permit a drum to be engaged by said transporter and then be conveyed from one location to another, said main frame comprising counterbalance means to minimize any tendency of said transporter to tip during the handling of a drum, said counterbalance means including removable weights at said main frame for varying the total weight of said main frame, said main frame including a compartment closed by a removable plate whereby said plate may be detached to expose said compartment, and said weights being located in said compartment.
A self-contained drum transporter comprising a main frame, a set of wheels mounted to and below said main frame for facilitating the movement of said main frame from one location to another, an outer mast assembly extending generally horizontally from said main frame, said outer mast assembly including a pair of legs said legs being disposed at an angle of at least about 90.degree. with respect to each other to permit said legs to straddle a pallet and dispose said main frame near a drum to be transported, an upstanding post assembly extending upwardly from said main frame at said outer mast assembly, said post assembly including a fixed guide post, an upper clamping mechanism for releasably engaging the chime of a drum, said upper clamping mechanism being movably mounted to said fixed guide post for selective vertical movement up and down with respect to said fixed guide post, a stabilizing mechanism for contacting the drum at a location below and remote from said upper clamping mechanism, said stabilizing mechanism being movably mounted to said fixed guide post for selective vertical movement up and down with respect to said fixed guide post, a lifting mechanism selectively controlling the vertical movement of said upper clamping mechanism and of said stabilizing mechanism to thereby permit a drum to be engaged by said transporter and then be conveyed from one location to another, said main frame comprising counterbalance means to minimize any tendency of said transporter to tip during the handling of a drum, said legs being adjustable in length, said post assembly including an outer sleeve assembly movably mounted to said fixed guide post, said clamping mechanism and said stabilizing mechanism being attached to said sleeve assembly, and said sleeve assembly comprising two C-shaped sleeves.
