Abstract: A self-propelled cable relay truck includes: a power transmission relay unit to which a power supply side cable configured to perform power transmission between a power supply and the relay truck, and a work machine side cable configured to perform power transmission between an electric work machine and the relay truck are connected to perform relay of the power transmission between the power supply side cable and the work machine side cable; a travel device configured to perform traveling operation so as to be able to move the power transmission relay unit; and a movement control unit configured to perform movement control of the travel device.

Abstract: A cable retractor for releasing and retracting an application cable. a cable retractor comprises a base; a spool having sides, the spool rotatably secured to the base to permit the application cable to be wrapped around the spool; a mandrel disposed concentrically within the spool, the mandrel being rotationally secured to the base to prevent axial rotation of the mandrel relative to the base; and the mandrel further having a recessed groove running lengthwise, and an internal cable having an outer connector and inner connector, the outer connector being connected through the spool to one end of the application cable, and the inner connector being exposed at one end of the mandrel from within the recessed groove.

Abstract: A cable handling system mounted to a mobile robot to dispense and retrieve cable at zero tension includes a cable reel drive and a downstream tension roller drive that includes an idler. As a cable passes through the tension roller drive, position along the length of the cable and/or the cable speed is monitored accurately by a sensor attached to the idler. A system controller in communication with the sensor controls the cable reel drive and the tension roller drive for dispensing and retrieving cable downstream of the tension roller drive.

Abstract: The present disclosure is of an automated cord reel apparatus comprising a housing; an electrical cord accommodated into the housing with one end of the electrical cord being mounted with a plug member connected to a wall receptacle and the other end of the electrical cord being mounted with an extension socket; and an electric cord unwinding/winding device for unwinding or winding the electric cord in response to a user option, wherein the electric cord, a motor adjusting a rotation direction of the guide unit, and a switch mounted at the extension socket to turn on/off and forwardly/backwardly rotate the motor.

Abstract: An auto-feed/rewind electric cord reel device for controlling a power supply cord of an appliance includes a reel bracket on which a cord reel is rotatably mounted. A motor bracket is movably mounted in relation to the reel bracket and a linkage connects the reel bracket to the motor bracket. A first motor is included for selectively actuating the linkage and moving the motor bracket in relation to the reel bracket. A second motor is included and is spaced from the first motor. An assembly is driven by the second motor for selectively rotating the cord reel in at least one direction.

Abstract: A cable reel is disclosed which permits rapid and simple pay out and deployment of cable, retention of cable in operating position, and rapid and controlled retraction of the cable, without overrunning or overwinding of the reel. The reel utilizes a highly functional slip ring capsule which provides positive and continual communications contact and transmission, regardless of adverse weather conditions, handling or operating stresses, or other conditions which would otherwise affect transmissions in prior art devices. It also reduces damage to cables; premature loss of cables through workers' carelessness or deliberate discard of loose cables; operational delays caused by missing cables, or by workers being required to hunt for individual lengths of cable; and delays or malfunctions resulting from having cables of the wrong size, length, weather resistance, etc. A slip-on member prevents damage to the cable tip when the cable is dropped, and a retractable cover prevents damage to the cable tip.
