The invention discloses a cable drum and a crane. The cable drum comprises a shaft, a shaft sleeve, a cylinder, a coil spring box and a coil spring, wherein the shaft sleeve is installed on the shaft in a sleeving manner and does not rotate relative to the shaft, and the shaft sleeve is provided with a first limiting part; the cylinder can rotate relative to the shaft, and a cable is unwound when the cylinder rotates in the first rotation direction, and is wound back when the cylinder rotates in the second rotation direction opposite to the first rotation direction; the coil spring box can rotate relative to the shaft and is provided with a second limiting part; and the coil spring is arranged in the coil spring box. According to the first and second limiting parts, when the cylinder rotates in the first rotation direction or rotates in the second rotation direction under the acting force of the coil spring, the end of the inner ring of the coil spring is in limiting fit with the first limiting part, the end of the outer ring of the coil spring is in limiting fit with the second limiting part, and the coil spring stores energy so as to wind the cable back. The crane comprises the cable drum. By means of the cable drum and the crane, the problem that a coil spring is difficult to install is solved.
