Description

Technical Field

[0001] The utility model relates to the technical field of magnetic cranes, and more particularly to a magnetic crane rotation drive device. Background Art

[0002] A magnetic lift is a type of lifting device that utilizes the principle of magnetism to lift objects. It uses electromagnets or permanent magnets to generate magnetic force to attract and transport ferromagnetic objects. It typically consists of a magnet, a hanger, a control system, and auxiliary equipment. The magnetic lift uses the force generated by the magnet to attract ferromagnetic objects. When the magnet approaches the ferromagnetic object, the magnet tightly attaches the object to the magnet. The operator controls the magnetic force, switching it on and off through a control system, thereby moving and releasing the object. Magnetic lifts are widely used in the steel industry, waste disposal, ports and logistics, and construction. They can efficiently and safely transport ferromagnetic objects of various shapes and sizes, such as steel plates, steel coils, and scrap metal.

[0003] However, the existing magnetic crane does not have the function of rotating the object at its lower end during use. As a result, when placing or stacking the lifted objects, manual labor is required to rotate the objects. This operation is not only time-consuming and labor-intensive, but also prone to danger, affecting normal use.

[0004] In addition, magnetic hoists are generally connected to lifting equipment through chains. When the magnetic hoist is used to lift irregular objects, the hanger is prone to tilting. However, most of the existing chains are fixedly installed at both ends of the hanger, so the inclination of the hanger cannot be adjusted, affecting the use effect. Utility Model Content
