  • Patent number: 4657307
    Abstract: An improved simple device for loosening, breaking up and removing concrete pavement slabs. The device has one or more planar vertical engagement members each having a generally horizontal slab-receiving slot. Each slot is bounded by upper and lower opposed edges and a crotch edge therebetween, all in fixed relative positions. The upper and lower edges extend forwardly to aligned upper and lower forward ends. The slot is dimensioned to accept and manipulate slabs, and to lift slab pieces taking advantage of the weight of the slabs to hold them for lifting. First and second pivot-mounting means are arranged to facilitate a can-opener like slab-manipulating motion.
