ABSTRACT:
An apparatus for breaking concrete surface layers, masonry walls, or like planar constructions, includes two foot members for engaging one surface of the construction at positions spaced apart from one another along a free edge of the construction, and a third member disposed so as to lie on the other side of the construction at a position substantially equally spaced from each of the foot members. An expansion device cuts between a body portion of the apparatus and the free end of the third member and operates to bring the three members into or out of gripping relationship with the construction with the third member furthest from the free edge of the construction. The first member is then moved relatively to the foot members, e.g. by tilting the apparatus, and this exerts a breaking moment on the constructions. Free standing and excavator-mounted versions of the apparatus are described in detail.
