Application of electromagnetic overhead crane

Electromagnetic bridge cranes are often used for indoor and outdoor handling and transportation of metal products and materials, such as steel ingots, structural steel, iron, scrap steel, steel, etc.

Highly used in the following environments: metal scrap yards, steel mills, recycling facilities, construction sites, ports and shipyards, power plants, automotive manufacturing and mining.

Including but not limited to the following work environments:

① Metal scrap yards: Electromagnetic bridge cranes are used to move and load/unload large quantities of metal scrap.

② Steel mills: Steel mills use electromagnetic overhead cranes to handle and move raw materials, such as scrap metal and molten steel, etc.

③ Recycling facilities: Recycling facilities use electromagnetic bridge cranes to sort and move various types of materials, including iron, steel, and non-ferrous metals.

④ Construction sites: Electromagnetic bridge cranes are used in construction sites to move and lift heavy materials such as steel beams and concrete slabs.

⑤ Automotive manufacturing: Electromagnetic overhead cranes are used in automotive manufacturing to lift and move heavy machinery, such as car bodies and engines.

⑥ Mining: Mining companies use electromagnetic cranes to move and lift heavy materials, such as ore and machinery.

Features of electromagnetic overhead crane


All compression structural part of crane’s components is made of high quality materials confirming with the regulations and standards, whose inspection report can be provided when required.


The welding of steel structures will be strictly checked and inspected by specialist and the inspection reports also can be provided on requirement.

Magnetic chuck

The magnetic chuck has huge magnetic force which can be used to lift and transport wide range of metal products and can handle large volume of metals at a time.


Top brand motors are installed with good performance and with Class F insulation and IP54 protective class.

Electric system

PLC control to all the mechanism and any speed requirement can be achieved.

Control system

Cabin with joystick panel, wireless control and pendant control can be your choices.


3 layers of painting is painted to protect the steel from rusting.


To ensure the safety of cranes and operations take various protective measures. Overloading limits, height limits, track terminal limits are used to protect mechanical systems and short circuit protection, phase loss protection, low voltage protection, power failure protection, and over current protection to protect power systems.

FAQ about Electromagnetic Overhead Crane

1. How does the electromagnetic bridge crane work?

An electromagnetic crane is a machine that uses electromagnetic principles to move steel objects.

Its main part is the electromagnet. When the current is turned on, the electromagnet will firmly attract the iron and steel objects and lift them to the designated place. Cut off the current, the magnetism disappears, and the steel object is put down. The electromagnetic crane is very convenient to use, but it can only be used when there is an electric current. It can be used in scrap iron and steel recycling and steelmaking workshops.

2. What are the safety precautions when using the electromagnetic bridge crane?

① When the lifting electromagnet stops working or rests, it should drop the heavy object to the ground, and the heavy object should not be hung on the hook.

② When working in rainy and snowy weather, in order to prevent the brake from becoming damp and ineffective, special emphasis should be placed on trial lifting to prove that the brake is reliable before working. In rainy and snowy days, the hanging should be slower.

③ During the operation, no one is allowed under the lifting weight, and no one is allowed to stand under the crane.

④ It is strictly forbidden to carry people on the hook, and it is strictly forbidden to stand on the top of the lifting object.

3. How to ensure the service life of the electromagnetic bridge crane?

In order to ensure the service life of the electromagnetic bridge crane, regular maintenance, inspection and repair are essential.

① Keep oil, water, gas and machine body clean. If the fuel is impure, there will be oil leakage, oil dripping, and even blockage of the oil circuit; if the purity of air and water is not high, it will affect the heat dissipation capacity of the engine and wear the body; if the surface of the body is not cleaned, it will corrode the body and bring unnecessary losses.

② Ensure sufficient supply of oil, water and air. If the supply of these energy sources is insufficient, it will lead to difficulty in starting the crane, poor lubrication, power reduction, severe wear, abnormal operation, and shortened service life.

③ Do a good job of daily safety inspection on the parts of the crane that are prone to problems. Cranes will be subject to vibrations of different strengths during the use of the crane, and the bolts and nuts in the fastening parts will become loose. Therefore, frequent inspections are required to prevent damage to the machine body due to looseness.

4. Can the electromagnetic bridge crane be customized according to specific needs?

Yes, electromagnetic overhead traveling cranes can be customized to meet specific industry needs and requirements. Customization can include crane dimensions, lifting capacity and control systems, among others.
