Columbus McKinnon has a long history of developing innovative products that have changed the material handling industry -- including the development of the first alloy chain in 1933. This alloy chain eventually replaced the industry-standard wrought iron chain used for overhead lifting and is the predecessor to today's Herc-Alloy® 1000 chain, hooks and lifting attachments. Made in America, CM Herc-Alloy® products, including the Hammerlok®, are made of superior triple alloy steel that provides the best strength-to-weight performance in the industry.
