  • Conductor stringing apparatus and process
    Patent number: 9178340
    Abstract: A line stringing apparatus includes in combination an electric motor, motor controller and a processor switchable between a pulling mode and a tensioning mode. An electric motor expends electrical energy when pulling the line and generates electrical energy when tensioning the line. The processor outputting commands to the motor controller for control thereof and for application of electrical energy from the batteries to the electric motor when in the pulling mode and for application of electrical energy generated by the electric motor to the plurality of batteries when in tensioning mode. The processor limits electric motor torque and speed based on operator commands for speed and torque in said pulling mode; and, the processor controlling electric motor torque in the tensioning mode.
    Type: Grant
