Overloading and Shock Loads All swivels are frequently subjected to overloads and shock loads unless a much larger swivel is used than is normally required. Common causes of overloads include using too long and too heavy strings of drill pipe, and pulling on stuck pipe. Shock loads result when the pipe is lifted suddenly. Severe shock loads are imposed when spudding gumbo off the bit. Probably the worst shocks of all are delivered by rotary jars when used for loosening stuck drill pipe.
