Abstract
A wheeled load carrier is disclosed in conjunction with a portable, drum-type motor driven drain cleaning machine, and the carrier comprises a wheeled frame structure on which the drum and drive motor are mounted and which is provided with wheels for transporting the drain cleaning machine along an underlying surface. The frame is provided with a pair of endless belt-type slide assemblies pivotally mounted thereon for displacement between first and second positions in which the belts respectively facilitate displacement of the drum cleaning machine upwardly and downwardly along a stairway and upwardly and downwardly relative to and along a truckbed or loading platform to facilitate loading and unloading of the drain cleaning machine relative thereto.
Claims41
In a sewer cleaning machine comprising frame means, snake drum means supported on said frame means for rotation about a drum axis, means for rotating said drum means, wheel means for supporting said machine for rolling movement on an underlying surface, and slide means on said frame means for supporting said machine for sliding movement relative to horizontal edge means elevated .from said surface, the improvement comprising:
- said slide means being mounted on said frame means for displacement relative thereto between a first position in which said slide means is positioned to engage first horizontal edge means elevated a first distance from said underlying surface and a second position in which said slide means is positioned to engage second horizontal edge means elevated from said underlying surface a distance greater than said first distance.
A carrier for transporting a load comprising, frame means, wheel means supporting said frame means for rolling movement along an underlying surface, slide means on said frame means for supporting said frame means for sliding movement relative to horizontal edge means elevated from said surface, and arm means mounting said slide means on said frame means, means for mounting said arm means in first and second positions relative to said frame means, said first and second positions of said slide means being angularly spaced apart by an obtuse angle, said slide means in said first position being positioned to engage first horizontal edge means elevated a first distance from said underlying surface, and said slide means in said second position being positioned to engage second horizontal edge means elevated from said underlying surface a distance greater than said first distance.
A carrier for transporting a load comprising, frame means, wheel means supporting said frame means for rolling movement along an underlying surface, slide means on said frame means for supporting said frame means for sliding movement relative to horizontal edge means elevated from said surface, and means mounting said slide means on said frame means for displacement between first and second positions relative to said frame means, said slide means in said first position being positioned to engage first horizontal edge means elevated a first distance from said underlying surface, and said slide means in said second position being positioned to engage second horizontal edge means elevated from said underlying surface a distance greater than said first distance, said means mounting said slide means on said frame means including arm means mounted on said frame means for pivotal displacement relative thereto about a horizontal pivot axis, said slide means being mounted on said arm means for displacement therewith, said frame means including a pair of horizontally spaced apart frame member extending upwardly relative to said underlying surface an said wheel means including a pair of wheels each outwardly adjacent a different one of said frame members, said pair of wheels being rotatable about a horizontal wheel axis, said arm means and said slide means thereon being between said frame members, said pivot axis being spaced above said wheel axis, and said slide means extending downwardly of said pivot axis in said first position and extending upwardly at an angle to a horizontal plane through said pivot axis in said second position, said arm means having horizontally opposite sides, and said slide means including endless belt means on each of said opposite sides.
