The breaker device for removing the tops of columns comprises a support structure composed of a plurality identical chain elements reciprocally linked by link couplings to form a closed chain which can surround a column which is to be topped. Each chain element bears a jackhammer provided with a plurality of interchangeable breaker punches, of varying lengths. Each chain element exhibits a plurality of holes which are distanced from the link couplings and which are for linking the chain elements. Each hole is aligned with a corresponding hole of an adjacent chain element. A pin is used for blocking adjacent chain elements in predetermined positions. The invention is useful for breaking the stop of a reinforced-concrete column without damaging the reinforcement elements thereof. The device can be adapted to columns having different diameters.
