Ironworkers
Ironworker is a class of machines that can shear, notch, and punch holes in steel plate. Ironworkers generate force using mechanical advantage or hydraulic systems. Modern systems use hydraulic rams powered by a heavy alternating current electric motor. High strength carbon steel blades and dies of various shapes are used to work the metal. The machine itself is made of very heavy steel to handle the enormous force that can be generated during use. Ironworkers are rated according to the force they can generate in tons; ratings usually start at 20 tons and go as high as 150 tons. Due to the reduction in the amount of man hours and effort needed to cut or punch steel sections, an ironworker is often an integral part of commercial manufacturing facilities and fabrication shops. They are easily re-tooled for various operations and can be operated by one person.
