Cutting up of a semi-plastic cellular light weight concrete body by passing string-like cutting members having, when operative, a substantially vertical extension in a horizontal direction therethrough is effected while the body to be cut is kept freely suspended from a perforated bottom of a hood-like suspension device, in which a sufficient vacuum is created to maintain adhesion by suction between the top of the body and said perforated bottom. The cutting members pass through and are moved along in slots formed in the bottom of the suspension device, their upper ends being actuated for movement above said bottom and their lower ends being separately actuated by driving means mounted in a stand separate from the suspension device but engaging therewith in a guiding manner, when cutting is effected.
