Specifications

Industrial cranes are essential in various industries, from construction to manufacturing. They are used for lifting and moving heavy loads, making work easier and more efficient. One of the most important components of an industrial crane is the electromagnet. In this post, we will discuss everything you need to know about industrial crane electromagnets.

What is an Industrial Crane Electromagnet?

An industrial crane electromagnet is a device that uses an electrical current to create a magnetic field. This magnetic field is used to lift and move ferromagnetic materials such as iron and steel. The electromagnet is usually attached to the end of the crane's hoist or trolley. When the current is turned on, the magnetic field is created, and the ferromagnetic material is attracted to the electromagnet. It is often used in industries that deal with steel products, such as construction, mining, and manufacturing.

How Does an Industrial Crane Electromagnet Work?

An industrial crane electromagnet works on the principle of electromagnetism. When an electric current flows through a wire, it creates a magnetic field around the wire. The strength of the magnetic field depends on the amount of current flowing through the wire. By coiling the wire around a core, the magnetic field can be concentrated, making it stronger.

In an industrial crane electromagnet, the wire is coiled around a core made of iron or steel. When an electric current flows through the wire, it creates a magnetic field around the core. The strength of the magnetic field depends on the amount of current flowing through the wire and the number of coils around the core.

The electromagnet is usually attached to the end of the crane's hoist or trolley. When the current is turned on, the magnetic field is created, and the ferromagnetic material is attracted to the electromagnet. The strength of the magnetic field determines how much weight the electromagnet can lift.

Types of Industrial Crane Electromagnet

There are several types of industrial crane electromagnets, each designed for specific applications. The most common types are:

• Circular Electromagnets: These are used for lifting and moving cylindrical objects such as pipes and bars. They have a circular shape and are designed to wrap around the object being lifted.
• Rectangular Electromagnets: These are used for lifting and moving flat objects such as sheets of metal. They have a rectangular shape and are designed to fit over the object being lifted.
• Bipolar Electromagnets: These are used for lifting and moving irregularly shaped objects such as scrap metal. They have two poles that can be adjusted to fit the shape of the object being lifted.
• Scrap Magnets: These are used for lifting and moving large amounts of scrap metal. They are usually attached to a crane's magnet grabber and can lift up to several tons of scrap metal at once.

Benefits of Using Industrial Crane Electromagnet

Using an industrial crane electromagnet has several benefits, including:

• Increased Efficiency: Electromagnets can lift and move heavy loads quickly and easily, reducing the time and effort required for manual lifting.
• Improved Safety: Electromagnets eliminate the need for manual lifting, reducing the risk of injuries and accidents in the workplace. It also can operate in harsh environments, such as high temperatures, dust, and moisture.
• Cost-Effective: Using an electromagnet can save money on labor costs by reducing the number of workers needed to lift and move heavy loads.
• Versatility: Electromagnets can be used in a variety of industries, including construction, manufacturing, and scrap metal recycling.

Some challenges of using an industrial crane electromagnet are:

• It requires a constant and stable power supply to maintain the magnetic field.
• It may not work well with non-magnetic or weakly magnetic materials, such as aluminum, copper, brass, and stainless steel.
• It may interfere with other electrical or magnetic devices nearby, such as computers, radios, and pacemakers.
• It may pose safety hazards if the current is interrupted, or the load is dropped accidentally.

An industrial crane electromagnet is a powerful and versatile tool that can improve productivity and quality in many industries. However, it also requires careful planning and management to ensure its optimal performance and safety.

To ensure safe and effective operation of an industrial crane electromagnet, some precautions should be taken:

• The operator should be trained and authorized to use the electromagnet and follow the safety rules.
• Regularly, check all the welding joint on non-magnetic guard board or other part.
• Check junction box and cable, repair or replace timely.
• Regularly examine the Electromagnet insulation resistance and Coil dc resistance.
• Inspect electric controlling equipment.
• Review electromagnet working current in thermal state. Stop it once over time and find how it happened.
• Keep the current and voltage stable, prevent useless magnetic disturbance, ensure fast 
• unloading, avoid high and middle voltage impact current coil.
• Use the electromagnet according to operating rules, don't change the current freely.
• It must be used in possible condition range.
• The electromagnet should be kept away from flammable or explosive materials.

Crane Lifting Electromagnets Selection

The needed parameter when choosing electromagnets.

• Crane type: e.g. 10+10T
• Lifting object: e.g. Lift square billet
• Lifting object's size and quality: e.g. Square billet: 150*150*12000mm，lift 6 pieces in normal temperature
• Controlling cabinet: ordinary type, magnetic power type, adjustable magnetic type
• Whether it needs inverter power supply or not: if internal contracting brake is direct current, don't need.

Industrial Crane Electromagnet Specifications

MW22 series Crane Lifting Electromagnet

Application: used for lifting steel ingot, large rolling billet early and structural steel. Different steel has different Magnetic circuit design. This series have many electromagnets for lifting different object: such as "I" steel, cogged ingot, beam slab and wire coil.

MW5 series electromagnet

Application: used to carry cast iron ingot steel ball and some steel waste.

MW61 series electromagnet

MW1 series electromagnet

MW84 series electromagnet

Application: this series is special for lifting middle or thick steel plate. Working is safe and fast. When it lifts long steel plate, it is better to use several electromagnets to ensure the safe loading. For some thick plate (6mm-32mm) the space between electromagnets is 3-4 m, the extra length is half of this space. There are different types for different lifting quality, 350 type and 400 type. 350 type is applied in thick plate factory, ship-building factory, machine making. It can lift one or several steel plates one time with adjustable magnetic control. 400 type lift steel plates as many as possible. If you need, we can design a special electromagnet for loading under high temperature of 700 Celsius.

MW04 series electromagnet

Application: the small round electromagnet is used to lift single steel plate or long steel plate. It also can be regarded as a fixture or hand to grasp some small object. You should consider the steel plate's width, thickness, weight when choosing electromagnet and its controlling equipment.
