The invention provides a cable pay-off drum, and aims to solve the problem of large resistance during rotation of the pay-off drum in the prior art. The cable pay-off drum comprises a revolving shaft, a lower drum body, a circular ring and a brake device, wherein a base of the revolving shaft is inserted into the center hole of a cable drum; the lower drum body is fixedly connected to the revolving shaft and is used for lifting the cable drum; the circular ring is fixedly connected to the lower end of the lower drum body; the brake device is arranged on the base and is used for braking a circular ring; the revolving shaft is vertical, and is rotationally connected to the base; at last three universal wheels are arranged between the lower drum body and the base; the revolving shaft is connected with the lower drum body through a spline; a bearing is arranged between the revolving shaft and the base; the top end of the revolving shaft is provided with an upper drum body which is matched with the lower drum body for clamping the cable drum. According to the cable pay-off drum, the bearing and the universal wheels are arranged, so that the resistance generated by rotating the drum body is lowered; the brake device is used for preventing the continuous rotation of the drum body, so that a lead is effectively prevented from moving forwards and becoming disordered; a baffle plate can be used for preventing the cable from sliding out of the upper end of the pay-off drum.
