| description | Tong systems having local hydraulic power generation. One system 500 includes a power tong for spinning tubulars; a first electric motor 523 functionally connected to the power tong 525; a plurality of hydraulic power consumers including a backup tong 510 for clamping a tubular string; a second electric motor 553 functionally connected to the plurality of hydraulic power consumers; and electronics to drive the first electric motor and the second electric motor. An alternative system uses a single electric motor and a switchbox (figure 4, 480) to select whether the motor drives the power tong or the hydraulics for the back-up tong. A disclosed method includes arranging a tong system in a hydraulic power configuration; supplying hydraulic power with an onboard electric motor to at least one of the hydraulic power consumers to position a tubular for make-up; arranging the tong system in a rotary drive configuration; supplying at least one of torque and rotation with the onboard electric motor to the power tong. |
