Description
Technical Field
[0001] The utility model relates to the technical field of slings, in particular to a multifunctional electromagnetic sling. Background Art
[0002] Electromagnetic lifter, full name electromagnetic crane, is a lifting equipment that works on the electromagnetic principle.

The multifunctional electromagnetic lifter can adjust parameters such as adsorption force and working speed according to different working environments and needs to adapt to various complex working environments.
[0003] Traditional multifunctional electromagnetic lifters are usually designed based on the principle of electromagnets. Their working principle is to control the magnetism of the electromagnet by controlling the on and off of the current, thereby achieving the adsorption and release of the lifter. The main parts of the electromagnetic lifter include the electromagnet, power supply system, control system and lifting machinery. When the current passes through the electromagnet coil, a magnetic field is generated, making the electromagnet magnetic. The magnetism of the electromagnet can attract ferromagnetic materials, thereby achieving lifting. When the current is cut off, the electromagnet loses its magnetism and the hoisted object is released.
