Abstract

Methods and apparatus for making and breaking tubular connections within a tubular string are disclosed. In certain aspects, a tong assembly includes gated power and back up tongs (102) coupled to a torque bar (112) . Jaws (306) of the tongs may be arranged circumferentially with support members (308) disposed between adjacent jaws to substantially complete a 360° closed circle. A hydraulic circuit may equally distribute fluid and pressure to actuate the jaws. The power tong may include a gated rotor driven by at least three drive motors (111) . The rotor may be selectively physically locked from rotation or movement by one or more rotor locks. Further, the tong assembly may include an interlock that prevents activation of the drive motors until the rotor locks actuate to unlock the rotor. Additionally, gate locks may secure the tongs and rotor when closed, and a releasable coupling arrangement may aid engagement of a motor to a rotor pump.
