General informations Due to its features, the spring cable reel is particularly suitable for mounting in small spaces; it enhances its performance when equipped with proper accessories such as adjustable bracket and ratchet device. The DR Italia spring cable reels are operated by Archimedean spiral springs with a wide range of performance. They are an effective and cheap solution for the electric power supply to mobile users. The electric cable is winded around the spool, which is made with an electrowelded sheet metal; one or more spiral springs are placed inside the spool, hooked on the rotation shaft. When the cable is pulled out, the springs are loaded and generate the required torque for rewinding the cable. In case of sudden return, the springs are automatically disengaged, avoiding breakage. The spiral springs may be of different section, length and quantity,according to the characteristics of the cables to be wrapped. Theyare made of high mechanical characteristics materials, and theyare placed inside the spool or in a suitable container outside. The electrical part (slipring and brush holders) is enclosed in a suitable sealed house, with different degrees of protection.
