RAIZOR support steel utilizes I-beam columns to provide greater strength in the direction of trolley travel. Because of the positioning of the runways close to the columns, no header is required. This can reduce headroom requirements significantly, resulting in the ability to lift your workpiece higher. RAIZOR columns use a knee brace that spreads the load on your floor. The knee brace can be turned either in or out at the time of installation and its position can vary from one column to another to avoid existing equipment. Columns are intended to be anchored to a minimum 6" thick concrete floor in good condition with epoxy anchor bolts.
