Title: TONG DOOR SECURING DEVICE
Abstract:
A power tong having a door that pivots in a vertical plane that is parallel to a plane that includes the axis of the tubular being made up or broken down by the power tong. The door is pivotally coupled to a power tong body for movement between an open position, that allows a tubular joint to be introduced through a throat and into a bay of the power tong, and a closed position that closes the bay of the power tong to enable the gripping and rotating components of the power tong to be engaged to grip and rotate the tubular joint introduced into the power tong. The power tong door includes structures that are engaged upon pivotal closure of the door with corresponding structures on the power tong body.
