The system for pulling wire through a conduit includes a cable puller and a remote controller. The cable puller may pull a wire through a conduit. The wire may be removably coupled to a cable coupler located on the rear of the cable puller. The cable puller may be inserted into a first end of the conduit and may progress to a second end of the conduit under the influence of a plurality of tractors. A camera that is mounted on a faceplate at the front of a housing of the cable puller may transmit one or more images to the remote controller. One or more visible light sources and one or more infrared light sources may provide illumination for the camera. Movements of the cable puller may be controlled remotely using the remote controller.

A device for use in removing a conveyance member from a material includes a displacement element (12, 1012) and a self-propelling driving element. The displacement element (12, 1012) is for being placed at least partly around a conveyance member (16) and for displacing material as the displacement element (12, 1012) is advanced along a conveyance member (16). The driving element is coupled to and movable with the displacement element (12, 1012) to advance the displacement element along a conveyance member (16).

The present disclosure relates to a method for festooning a power cable while deploying it in a deployment site comprising a rail having a start and an end, the method comprising the steps of: providing the cable with a plurality of cable holders slidably movable along the rail, each two consecutive holders being spaced at a holder predetermined distance on the cable; providing a festooning apparatus after the start of the rail, the festooning apparatus comprising a lowering device movable between a raised position and a lowered position; deploying the cable along the rail by repeating the following sub-steps: engaging on the rail one holder after the other and moving them thereon; when one holder oversteps the festooning apparatus, operating the festooning apparatus to move the lowering device from the raised position towards the lowered position, thus engaging the cable at a point between two consecutive holders; when the lowering device reaches the lowered position, obtaining a sagged portion of cable and a shortening of the holder predetermined distance; operating the festooning apparatus to move the lowering device from the lowered position towards the raised position, thus disengaging it from the cable; fixing the shortened holder predetermined distance between two consecutive holders at each side of the sagged cable portion; and advancing the sagged cable portion along the rail.

A computing apparatus configured to implement travel control for a carriage of an automated cable runner (ACR) along the pathway of the ACR from a desired start point to a desired end point to deploy cabling into the tray from the start point to the end point, the computing apparatus includes a processor; a memory; and a communication interface coupled to each of the processor and the memory. The processor is configured to: receive a cabling deployment job request; and instruct a carriage with a cabling connected thereto via a cable holder to travel along the pathway from the start point to the end point to deploy the cabling in the tray to fulfill the cabling deployment job request.

A headlock cable installation system includes a headlock assembly, an extension rod, and a flexible headlock cable. The headlock cable installation system is used for installing a pre-connectorized cable assembly. The headlock assembly defines a cavity configured to receive a connectorized end of the pre-connectorized cable assembly. The flexible headlock cable has opposite first and second ends. The first end of the headlock cable is coupled to the headlock assembly, whereas the opposite second end of the headlock cable is adjustably coupled to the extension rod. Adjustment of the second end varies a position of the headlock assembly relative to the extension rod.

A device for capturing a line passed into a cavity on a first side of a structure and retrieving the line through to a second side of the structure, the device comprising: (a) a first conduit adapted to define a pathway between the first and second sides of the structure and including: first and second lateral guide members that are opposed and each define a first surface that extends into and along the inside of the first conduit; (b) a mounting member for the first conduit; and (c) a resiliently flexible member capable of being passed through the first conduit and defining a stem portion and a loop portion in the cavity to capture said line.

An embodiment describes a method for installing a single power cable span in a tunnel having an entrance and an exit. The method includes positioning a head portion of the single power cable span near the entrance and laying the single power cable span in the tunnel past the exit. The laying of the single power cable span comprises repeating a plurality of sub-steps until the head portion reaches an endpoint outside the tunnel. The plurality of sub-steps includes connecting a trolley at the entrance in a slidable manner on a rail longitudinally extending along the tunnel between the entrance and the exit, joining the trolley to a pulling rope and to the single power cable span, and moving the trolley along the rail by pulling the pulling rope by a predetermined length. Another embodiment relates to an equipment for installing a single cable span in a tunnel.

Disclosed is a threading device suitable for a building electrical pipeline. The threading device comprises a fan, a take-up and pay-off main machine and a connecting hose. A take-up state induction mechanism mainly composed of a bent pipe converging device, a first rotating shaft, a bent pipe converging device lifting spring and a first microswitch is creatively arranged in a ventilation bin. When a strong wire is tightened, the bent pipe converging device is easy to rotate along with tightening of the strong wire, and the strong wire makes contact with the first microswitch in time when being tightened. After the strong wire is loosened, the bent pipe converging device can automatically return under the action of the bent pipe converging device lifting spring, and the take-up state of a wire wheel is recovered.

Provided is an offshore structure, especially offshore wind turbine, including a platform that is connected to the seabed, especially via a foundation that carries the platform, and an appliance, wherein it comprises guiding means for guiding at least one tube or cable along a guidance path from a respective entry point at which the tube or cable enters the platform to a respective connection point at which the tube or cable is connected or connectable to the appliance.

An automated cable runner (ACR) for a cabling tray. The ACR includes a pathway, a carriage operable to travel along the pathway, a plurality of supports connectable to the pathway and connectable to the tray and configured to support the pathway over the tray, and a cable holder attached to the carriage. The carriage is operable to autonomously travel along the pathway from a desired start point to a desired end point to deploy cabling into the tray from the start point to the end point.
