摘要： A power tong assembly and backup tong assembly are disclosed. The power tong assembly includes a drive motor driving a drive gear engaged with a rotatable portion of a bearing assembly. The rotatable portion of the bearing assembly is connected to a cylindrical rotor positioned concentrically about jaws that grippingly engage and rotate a first tubular member when the portion of the bearing assembly rotates. The backup tong assembly comprises a pair of diametrically opposed gripper assemblies each having a cylinder with a cylinder rod, connected to a head member, connected to a pair of gripper members with gripping surfaces, so that extension of the cylinder rods causes the gripper members to grippingly engage a second tubular member. The power tong assembly and the backup tong assembly may be concentrically aligned to connect and disconnect the first and second tubular members.
