Technical Field

[0001] The utility model relates to the technical field of power equipment, in particular to a pay-off rack. Background Art

[0002] With the development of society, cables are being installed in all corners of the city, and these cables require specialized payout racks for the wire and cable industry. These payout racks can be used during line construction. The reel with the wire wound around it is movably mounted on the payout rack's horizontal axis to support the reel. During the payout process, the reel can rotate, allowing the wire to be pulled smoothly from the reel.
