Abstract: A wrap around tong system is provided with a rotary drive tong and backup tong that remain positioned around the pipe string as the pipe string is run into or out of the wellbore. The tong system is affixed to the drill floor and does not rotate or move laterally to the pipe string. The power tong system is moved upwardly and downwardly to position the rotary drive tong and backup tong at appropriate postions on the pipe string. The rotary drive tong provides both spinning and torquing for making or breaking connnections.

Abstract: The apparatus is connected to a member on the elevator that moves if and when the slips move between the open and closed positions. The member is locked in a preselected position that attends the position of the slips when the elevator is considered safe. When the member is in that safe position a wireless signal is generated by the apparatus part on the elevator and received by a receiving part of the apparatus in a convenient remote location such as the drillers position. In response to the received signal, the receiving part produces a visible signal to indicate that the slips are in the preselected position.
