Cable reels are classified into two categories based on their driving form: non electric and electric; There are two types of cable arrangement: axial single row and axial multi row; According to the position of the collector slip ring, it can be divided into two types: the slip ring internal installation type and the slip ring external installation type; According to the winding material, it is divided into Kaihui cable drum and hose drum. Among them, non electric types include: elastic (TA) type, heavy hammer (ZC) type, and magnetic coupling type (JQC); Electric type includes: magnetic coupling type (JQD), torque motor type (KDO), hysteresis type (CZ), and variable frequency control type (BP), etc&Nbsp; Principle, performance, and application of elastic a Working principle: The working principle of an elastic cable reel is similar to that of a steel tape measure, using a worm coil spring as the power to wind the cable. When the cable is pulled out, the coil spring is tightened to store energy. When the external force is withdrawn, the spring releases energy and the drum will automatically retract the cable. b. Performance and characteristics: Simple installation, good synchronization performance, low cable tension, but easy fatigue of springs, short service life. c. Scope of application: Applicable cables: power cables with a cross-sectional area of less than 35mm and signal cables with a core of less than 24; Winding length: not exceeding 30m; Applicable equipment: such as electromagnetic suction cups, grab buckets, electric trolleys, etc. Heavy hammer type a Working principle: The heavy hammer type cable reel is a mechanical device that uses the principle of energy storage when the heavy hammer is lifted to automatically coil cables. When the cable is pulled out, it drives the cable reel to rotate, thereby driving the steel wire rope reel coaxial with the cable reel to rotate, lifting the heavy hammer and storing potential energy. When the drum needs to coil the cable, the heavy hammer descends to release potential energy. Under the tension of the steel wire rope, it drives the cable reel coaxial with the steel wire rope reel to rotate and synchronously coil the cable. b. Performance and characteristics: simple structure, stable and reliable performance, convenient installation and maintenance. c. Scope of application: Applicable cables: cables with a cross-sectional area of 25-50 mm. Winding length: less than 50m. Applicable equipment: Especially suitable for harsh working conditions, such as various metallurgical and mining vehicles such as ladle cars, molten iron cars, slag pans, etc
