“Big Pete” Ramagos, rigger at work on Douglas Dam, Tennessee, June 1942. A rigger is a person or company which specializes in the lifting and or moving of extremely large and/or heavy objects. Riggersuse equipment expressly designed for moving and lifting objects where ordinary material handling equipment cannot go.
My son and I were trying to figure out where the name “big rig” came from recently. Now it all makes sense.
