The invention discloses a multi-cable pay-off device for cable erection. A first slide block is arranged at one side of a vertical column, first slide rails are arranged at the two ends of the first slide block, and a clamping jaw is arranged at one side of the first slide block; a first belt wheel is arranged at one end of a first rotary shaft; a clamping jaw is arranged on a second slide block;the upper end of the first slide block is connected with a top plate through a first oil cylinder; the upper end of the second slide block is connected with the second slide block through a second oilcylinder; and a drive device comprises a first double-end motor arranged on the upper part of the top plate, second rotary shafts connected with the two ends of an output shaft of the first double-end motor, and second belt wheels installed on the second rotary shafts, and the second belt wheels are connected with the first belt wheel through a belt. According to the multi-cable pay-off device for cable erection, the clamping jaws are arranged at the two ends of a vehicle frame, and a reel is supported by virtue of the clamping jaws, so that the reel is prevented from being separated from a pulley during rotation, and the stability of the reel is ensured; and moreover, the drive device is arranged on the upper part of the top plate, and the reel is driven to rotate by virtue of the drivedevice, so that manual wire drawing is avoided, the labor amount of workers is reduced, and the pay-off efficiency is increased.
