I work in a heavy equipment/semi truck shop. The torque wrench used on the wheel lugs is cal'd every 6 months, and the details are recorded. Similar to aviation work, everything is logged. 80,000 lbs at 65 mph causes a lot of oh shit in a hurry if something isn't right. At best its just massively expensive. Cal and double checking is absolutely necessary for everyone's safety, for our company reputation, and for the insurance lawyers.
