Abstract:
A system for unwinding and laying wires on a fixed supporting structure with obstacles to the laying of the wire, comprising:a device for carrying a wire reel from which the wire to be laid is dispensed;means for unwinding and laying said wire;wherein said device for carrying wire is a unit structured and arranged to be held against motion during the unwinding and laying of said wire;a vehicle to which said means for unwinding and laying said wire is mounted said vehicle being movable along a laying path;wherein said means for unwinding and laying said wire comprises a wire pulling unit with first and second clamping devices for gripping said wire, said first and second clamping devices being mounted upon a support at a predetermined distance from one another in an axial direction of the wire and a moving direction of the vehicle, each one of the first and second clamping devices being selectively adjustable from a clamping state wherein said clamping device grips said wire and a declamping state wherein said clamping device releases said wire and wherein each clamping device is positionable from an extended clamping position wherein said clamping device is in its clamping state with said wire being gripped and enabled to extend beyond an obstacle located along said laying path to a retracted declamping position wherein said clamping device is retracted to a clearance position transversely spaced from said obstacle.
