Publication number: 20200295555Abstract: The process and apparatus for tension stringing a conductor through above-ground supports uses a length of rope affixed to the conductor wound on the tensioning machine and pulled by the puller machine. Each of the first and second stringing apparatuses includes an onboard control system which controls each of the first and second stringing apparatuses in pulling mode or in tensioning mode. Each of the first and second stringing apparatuses includes a motor/regenerative brake or other means of inducing tension into the conductor. Each of the machines includes a wireless transceiver which is hard-wired to said onboard control systems. A first operator resides on the puller machine and selects the machine as a puller machine operating in pulling mode using an onboard control system. An observer resides on the tensioner and selects the second machine to be the tensioner.Type: ApplicationFiled: March 10, 2020Publication date: September 17, 2020Applicant: TSE International Inc.Inventors: CODY GLENN JACKSON, JOHN JERRY MARTIN, ANDREW CALVIN LACKMAN

Patent number: 9178340Abstract: 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: GrantFiled: March 8, 2012Date of Patent: November 3, 2015Assignee: TSE International, Inc.Inventors: Dutch Johnson, John J. Martin

Patent number: 4508281Abstract: A rotary drum cable winding apparatus particularly adapted for constant tension pulling operations in conjunction with stringing aerial electrical cables includes a hydraulic drive and control system utilizing a variable displacement, variable torque hydraulic motor supplied by a pressure compensated hydraulic pump. The motor has a built-in displacement control which is responsive to a predetermined pressure set point which may be varied by a pilot control pressure signal to increase motor displacement per revolution and output torque for a given motive fluid supply pressure. The increasing torque requirements and the reduced rotative speed of the rotary drum coincide with the requirement for relatively constant tension and constant speed of the messenger line or cable being wound on the drum.Type: GrantFiled: August 15, 1983Date of Patent: April 2, 1985Assignee: TSE InternationalInventor: Robert J.
