The Roper Whitney floor- mounted manual bending brake is a precision machine for use in bending mild steel and other sheet metals, including aluminum, brass, bronze, copper, duralumin; lead, montel metal, silver, carbon and stainless steel within the rated capacity of 16 gauge mild steel and 18 gauge stainless steel. The machine is fabricated of sturdy steel plate with appropriate gussets, braces and trusses; three basic longitudinal members (upper-beam, lower-beam and bending leaf/apron control the clamping pressure and stress incurred in overcoming the yield strength of the material being formed. As with all Roper Whitney products this handbrake is built for years and years of use. The machine is a 10' machine rated for 16 gauge mild steel and it weighs 2,660 pounds. The machine is built in Rockford, Illinois and has been a part of the Roper Whitney line of equipment since the 1970's.
