Electromagnetic overhead crane is a device that utilizes electromagnetic suction to lift and move heavy objects. It usually consists of electromagnet, wire rope, lifting hook and lifting mechanism. Its working principle is to generate a strong magnetic field by energizing the electromagnet, and then place it above the object that needs to be lifted, and use the magnetic field to attract the metal material on the surface of the object to achieve lifting. When the object needs to be released, just disconnect the current, the magnetic field disappears and the object is released.
Electromagnetic Overhead crane features
- Magnetization of power failure
Magnetization can prevent the objects under the spreader from falling accidentally when the equipment suddenly loses power, so as to avoid causing safety accidents, and the general time of magnetization is 15-30 minutes. - Simple and convenient assembly
Any detachable electromagnetic spreader, round disk, square disk, oval disk and electromagnetic hanging beam can be installed according to the usage. - Speed regulation of each organization
The speed regulation of each mechanism can be provided according to the user’s requirements, which can reach 1:10 or greater.
