Grade 80 chain is commonly used for overhead lifting applications because of its excellent energy absorption properties. Peerless Grade 80 chain meets the latest guidelines of the National Association of Chain Manufacturers (NACM) and ASTM A391/A391M. This is in line with the higher 4-to-1 design factor required by the International Standards Organization (ISO).
For fast identification, Grade 80 chain is embossed USA and stamped P8. For qualitycontrol purposes, and chain is date coded for easy traceability.
Large Diameter Chain
Has heavy lifting ranges of 100,000 to 454,600 lbs (3 and 4 leg slings), large diameter chain can be used for virtually any heavy lifting application. When Peerless developed their revolutionary 8 step manufacturing process, we didn’t make any compromises. Our goal was to manufacturer the best quality large diameter chain in the market today. We have incorporated technology advances such as flash welding – the best and most consistent way to weld chain today. Great chain is a function of design as well. You will find the strength enhancing features of triple alloy with nickel, chromium, molybdenum and links with a single weld. When you consider all of these enhancements, plus the assurance of proof testing and certification, you will realize that Peerless large diameter alloy chain is tough enough to handle any lifting application.
