Abstract
A suction cart suctions away the gases and dust produced during flame cutting processes and catches the scrap metal produced. The suction cart can travel underneath the flame cutting bench and is outfitted with at least one suction pipe, which emerges into a suction duct, is configured so that it is able to handle the disposal work for materials located underneath the flame cutting bench. A cleaning blade or rake is arranged on the suction cart, the cleaning blade or rake being able to be lifted and lowered onto the floor underneath the flame cutting bench.
