B555/B999 AIR RAMS PNEUMATIC BREAKERS – PERFORMANCE IN EXTREME HEAT

Air Rams are designed for skid-steer loaders, rubber-tired backhoes and excavators.

Ideal for use on roads and bridges, rock, utility applications and in steel mills for ladle and furnace cleaning where heat can be detrimental to hydraulic breakers. These hammers have proven themselves since 1973.

Furukawa / FRD is the industry leader in pneumatic rock breaker & rock hammer attachments for mining, construction & excavating equipment.
