Description

Technical Field

[0001] The utility model relates to the field of cable pay-off racks, in particular to a liftable cable pay-off rack. Background Art

[0002] The construction of wires and cables is often encountered in engineering projects. Since the wires and cables purchased from manufacturers are all wound on large-diameter steel frame reels, they usually need to be reeled in sections. Since the diameter of the reel for winding the cables is usually more than two meters and the weight reaches several tons, if the wires need to be paid out, the reel needs to be lifted by a crane for paying out. Paying out the wires usually requires the cooperation of multiple people, which is very inconvenient to operate and has poor safety. Therefore, this article provides a liftable cable payout rack.
