The present disclosure provides a tong system which includes a tong assembly and at least one string gripping device. The tong assembly is configured to engage a rod or tubular string at the junction between a first rod or tubular and a second rod or tubular of a rod or tubular string and unthread the first rod or tubular from the second rod or tubular. The tong assembly can also thread the first rod or tubular onto the rod or tubular string. The string gripping device is configured to hold a tubular string for at least a portion of the time. The tong system further holds the rod or tubular string against torque applied onto the first rod or tubular by the tong assembly.
