Electromagnetic Overhead Crane Overview

An electromagnetic overhead crane is a kind of material handling equipment, equipped with a detachable electromagnetic chuck and a corresponding operating system to handle and lift metal objects. The main part of the electromagnetic crane is the electromagnet. The lifting capacity of the electromagnetic overhead crane including the weight of electromagnetic is 5 to 32 tons. The working class of electromagnetic cranes is A5 and A6. The magnetic retentive time is 10 to 30 minutes. The overhead crane is used in metallurgy factories or outdoor places to load and transport electromagnetic black metal materials, such as steel ingot, merchant steel pig iron, etc.

When the current is connected, the electromagnet will firmly attract the steel objects and lift them to the designated place. Cut off the current, the magnetism disappears, and the steel item is put down. The electromagnetic bridge crane is equipped with a detachable electromagnetic spreader and a corresponding operating system, which consists of the main beam, a travelling mechanism, a hoisting trolley, and an electrical system. The shape of the electromagnetic spreader can be customized according to the shape of the material to be lifted. The electromagnetic spreader can be a disc-type magnetic spreader, a square magnetic spreader, etc. Our electromagnetic cranes are equipped for cabin operation with rain protection outside the cabin.

Components of Electromagnetic Bridge Crane

An electromagnetic bridge crane is mainly composed of a crane bridge, trolley, crane travelling mechanism, cab, electrical system, electromagnetic system, etc.

• Lifting mechanism: reducer, drum, motor protection grade F, domestic or world top motor brands, such as Jiamusi, Nanjing Motor, ABM, etc.
• Wheels: Forged, compact structure, easy maintenance, high transmission efficiency, and long service life.
• Travelling mechanism: Adopt well-known crane motor and reducer suppliers at home and abroad, such as Nanjing motor, double brake SEW, etc.
• about the material. All compression structures of crane components are made of high-quality materials that comply with regulations and standards, and inspection reports are available upon request. Q235B/Q345B carbon structural steel adopts seamless one-step forming technology, which is more sturdy and beautiful. Suitable for different operating temperatures.
• About welding. The welding of steel structures will be strictly inspected and inspected by special personnel, and inspection reports can also be provided upon request.
• About the magnetic chuck. Magnetic chucks have a huge magnetic force and can be used to lift and transport a wide range of metal products, handling large quantities of metal at once.
• About the motor. Install top brand motors, good performance, insulation class F, protection class IP54.
• About the power system. PLC control for all mechanisms and any speed requirements can be realized.
• About the control system. Cabins with joystick panels, wireless controls, and pendant controls are your choice.
• About appearance. Coated with 3 paints to protect the steel from rusting.
• About safety. Take various protective measures to ensure the safety of the crane and its operation. Overload limit, height limit, and travel limit are used for mechanical system protection, short circuit protection, phase loss protection, low voltage protection, power failure protection, and overcurrent protection are used for electrical system protection.

Applications of Electromagnetic Crane

Electromagnetic bridge cranes are generally used in metallurgical plants or outdoor places, and some shops also use them to handle materials.
Electromagnetic overhead cranes can be used for loading, unloading, and transporting indoor and outdoor ferrous products and materials, such as steel ingots, structural steel, iron, scrap iron, steel, etc.
Overhead cranes are used in metallurgical plants or outdoor locations to load and transport electromagnetic ferrous materials such as steel ingots, commodity steel, and pig iron. The lifting capacity is 5-32 tons.
The electromagnetic crane adopts a detachable electromagnetic chuck as the reclaiming device. It is widely used in the lifting and moving of magnetic black products and materials such as steel ingots, section steel, pig iron blocks, scrap iron, and scrap steel in metallurgy and machining workshops.
An electromagnetic suspension girder bridge crane uses a beam that is evenly suspended by electromagnetic suction cups as a reclaiming device. It is mainly used for loading unloading, and transporting steel plates, ingots, billets, and other long ferrous metal products in metallurgical plants or warehouses.
