Ruger Industries Inc., headquartered in Solon, Ohio, has introduced a program for the custom design and manufacture of stainless steel portable crane products. These floor cranes feature stainless steel construction, stainless steel hydraulic pumps and antimicrobial wheels, making them appropriate for pharmaceutical manufacturing, clean room processing, electronics manufacturing or food processing applications. Also known as engine cranes or engine hoist products, they eliminate many backbreaking activities while navigating standard door openings, narrow aisles and elevators. Ruger manufactures both manual portable cranes and full power portable crane products in stainless steel. Lifting capacities range from 500lbs up to 6000lbs. Full power driveable versions are suitable for repetitive lifting and maintenance applications. They feature structural tubing of 1/4in to 1/2in wall thickness, large lubricated casters and totally welded fabrication.
