Description

technical field [0001] The invention relates to a cable winding device, in particular to a frequency conversion driven cable winding device. Background technique [0002] The cable reel is a cable winding device that provides power supply, control power supply or control signal for large mobile equipment. It is widely used in port portal cranes, container cranes, ship loaders, tower cranes and other similar heavy machinery and equipment. [0003] The frequency conversion drive cable reel is controlled by the frequency converter, so that the cable reel can achieve various required torque characteristics. PLC is used for precise calculation and control, fully considering the requirements of dynamic and static characteristics and safety and reliability, and has many advantages such as small motor capacity, good torque characteristics, stable performance, and convenient adjustment. It is suitable for receiving large-scale and long-distance power supply cables. Contents of th...
