Abstract
A dolly for lifting and transporting cumbersome objects such as barrels is disclosed having a wheel supported base and a pair of horizontally disposed arms supported on that base in cantilever fashion which arms are simultaneously movable in a vertical direction. An open ended object clamp for gripping the object to be transported is pivotably connected to the arms near the free ends thereof so that the object clamp may be rotated about a horizontal axis and the open end thereof directed downwardly to engage an object from above or that open end directed horizontally to engage an object from the side despite the fact that that object may be against a wall or other obstacle.
Claims4
A carrier for lifting and moving cumbersome objects comprising:
- a hand propellable cart including a base consisting of a generally horizontally disposed rectangular frame open at one end to allow the carrier to straddle an object to be lifted and rollably supported on wheels for movement in generally horizontal directions;
- a pair of generally horizontally extending arms supported on the base by means providing movement relative thereto in a generally vertical direction;
- an open ended object clamp for selectively gripping objects to be transported, the object clamp when gripping the object extending less than completely around the object and including a rigid U-shaped portion, a pair of jaws each pivotably attached to a respective side of the U-shaped portion, and means for moving the jaws toward one another to grip the object said means including cable for each jaw which is attached to the jaw near the free end thereof and hand actuable crank means disposed on the rigid U-shaped portion for tensioning each of the cables to move the free ends of the jaws toward each other, the jaws pivoting about respective free ends of the U-shaped portion whereby an object may be gripped between the jaws and the rigid U-shaped portion;
- pivot means connecting the object clamp to the arms near the free ends thereof to allow the object clamp to be rotated freely about a generally horizontal axis whereby the open end of the object clamp may be directed downwardly to engage an object from above and directed horizontally to engage an object from the side.
