A system for unwinding and laying wires including a device for carrying a wire reel from which the wire to be laid is dispensed an device for unwinding and laying the wire, the device for carrying wire structured and arranged to be held against motion during the unwinding and laying of the wire, a vehicle to which the for unwinding and laying the wire is mounted, the vehicle being movable along a laying path. The device for unwinding and laying including a wire pulling unit with first and second clamping devices for gripping the wire, the first and second clamping devices being selectively adjustable from a clamped state in which clamping device holds the wire and a declamped state wherein the clamping device releases the wire and the first and second clamping devices being positionable from an extended clamped position in which the clamping device extends transversely beyond an obstacle located along the laying path a retracted declamped position in which the clamping device retracts to a clearance position transversely spaced from the obstacle.
