The invention provides an intelligent electromagnet lifting appliance and belongs to the technical field of machining technologies. An electromagnetic hanging beam of an electromagnetic lifting appliance has the function that the electromagnetic hanging beam is mounted on a floor type 40T double-beam gantry crane, the span is 30 meters, and the electromagnetic hanging beam keeps magnetism in power failure and lowering a main hook when equipment fails and is powered off. According to the electromagnetic lifting appliance, an electromagnet is divided into two parts, a double-coil sub-control mode is adopted, and electrical pure iron is adopted as a main magnetic conducting material. The electromagnetic lifting appliance has the technical conditions of lifting bulk H-shaped steel and sucking and lifting 12-meter bundled deformed steel bars, H-shaped steel and steel plates. A control system of the electromagnetic lifting appliance is a contactless high-reliability system, and a silicon controlled rectifier module technology is adopted. The electromagnetic lifting appliance adopts a power supply inversion technology. A charging part of the electromagnetic lifting appliance is a fourth-generation automatic charging control panel, and the automatic charging panel is composed of a step-down rectifier transformer, a synchronous transformer TR2, a three-phase rectifier module and a group of automatic control circuits. A control system of the electromagnetic lifting appliance selects GTBM-UPS-15KW series inverter control equipment.
