PURPOSE:To make the function of a traverser simple and suitable for practical use, by installing a rotation detector for detecting the rotation of a drum by means of pulses and a motor which turns a feed shaft by the given number of revolutions according to generation of the pulses. CONSTITUTION:In a winding device for cable and wire, employed in aerial transmission line construction, which is provided with a traverser body 1 capable of free control of a position where the cable is wound around a drum 3, and a feed shaft 5, having a guide groove, that moves the body 1 in parallel to a drum shaft 9 at a given speed, a rotation detector 16 for detecting the rotation of the drum 3 by means of pulses is provided, and a motor 17 turns the feed shaft 5 by the given number of revolutions according to generation of said pulses. This eliminates a stepless transmission gear, an electromagnetic clutch, a rectifier and the like which are needed in the case of conventional types because of that the traverser body is moved through continuous transfer of the rotation of the drum, and employment of an inexpensive 3-phase induction motor, which can be easily procured and can freely run normally or reversely, may suffice for operation of the device, resulting in reduction of the cost. |
