These chains have proven to be the most reliable conveying medium when it comes to the aggressive nature of log yard applications. They are typical where continued impact and abrasion affect the operational life of the chain system employed. These chains include fully heat treated parts, with welded pin and bush to ensure maximum chain life and performance.
