Abstract
The concrete removal device and system which can be used for fast, efficient removal of concrete sidewalks, driveways, slabs and other concrete constructions. A concrete removal device and system includes an operator capable of drilling a concrete slab to set an anchor bolt and driving a forklift equipped with a concrete removal device to elevate a concrete slab to deposit it in a dump truck or dumpster for hauling away from the removal site.
Claims20
A concrete removal device, comprising:
- an angle iron having a horizontal wall and a vertical wall, the angle iron configured to support the weight of a concrete slab during removal;
- at least one channel fixedly attached to both the horizontal wall and the vertical wall of the angle iron, the at least one channel forming a passageway dimensioned to receive forklift forks and stabilize the device during lifting;
- a first keyhole-like slot extending through the horizontal wall of the angle iron, the first keyhole-like slot configured to receive and engage a first anchor bolt embedded in the concrete slab, thereby enabling secure lifting of the concrete slab without segmenting the slab into smaller sections;
- at least one reinforcement plate positioned between gussets attached to the angle iron, the at least one reinforcement plate reinforcing the horizontal wall adjacent to the first keyhole-like slot to prevent deformation during lifting;
- whereby, upon engagement with a forklift, the concrete removal device facilitates lifting and transporting the concrete slab as a single, intact piece.

A method of removing a concrete slab, comprising:
- (a) drilling an anchor bolt into the concrete slab;
- (b) positioning a concrete removal device on forks of a forklift, the concrete removal device having at least one keyhole-like slot configured to accommodate the anchor bolt;
- (c) aligning the forklift forks through at least one channel in the concrete removal device and securing the concrete removal device to the forklift forks;
- (d) positioning the concrete removal device over the anchor bolt so that the keyhole-like slot receives the anchor bolt;
