ABSTRACT:
A pavement and masonry stone cutter includes an upper tool supported for vertical up and down movements and which is mounted in an approximately C-shaped frame above a support table for the stone material to be cut; a lower tool is disposed below the support table and is associated with the upper tool with the lower tool passing through an opening in the support table so that the upper tool and the lower tool enter into cutting operation at the same time for precise splitting; a support table during splitting is lowered in a controlled manner with respect to the lower tool; the upper and lower tools may be in the form of individual cleaving wedges which are hydraulically operated to move towards and away from one another; the chambers for the hydraulic cylinders are in fluid communication.
