Cable reel is a cable winding device which provides power supply, control power supply or control signal for large mobile equipment. It is widely used in port gantry crane, container crane, loader, tower crane and other similar working conditions of heavy machinery equipment. Cable drum main products are in the following forms: counterweight type, torque motor type, hysteresis type, frequency conversion drive type. Cable drum is divided into: spring driven cable drum and motor driven cable drum. Spring-driven cable reel is used to control the rolling and discharging of cables, mainly used in cranes, stacking devices or wastewater treatment technology and other occasions. Helical spring driven reels are more reliable, less expensive and can be interchangeable with electric reels. This is especially true for mobile devices without internal power. The flange of the spring-driven drum is made of galvanized sheet metal and the outer edge of the flange is crimped. The core of the reel is made of metal sheet, and the outer layer is protected by polyester coating, which can prevent corrosion.
EM Series constant tension cable reels are the earliest cable coiling device developed by the company. Through years’ development,the Company has now developed universal cable reels,multi-ring(signal)cable reels to satisfy various special needs.The products of this series are characterized by mature tecnology and stable and reliable performances.They have been awarded five utility model patents and one invention patent and are widely used in metallurgical and hoist industries.
EM-I has a small volume, light weight and compact structure. It is suitable for mobile equipment such as small electric grab bucket, repair car and in-plant transfer car.
