Industrial Lifting Electromagnet

The Industrial Lifting Electromagnet is designed for crane handling of ferromagnetic steel plate in steel stockyards, fabrication lines, plate processing areas, and material transfer stations. The MW84 series uses a rectangular magnetic body to establish a stable contact area across flat plate surfaces. It is intended for handling medium-thickness plate where lifting quantity, plate width, plate length, surface condition, and operating temperature have been evaluated together.

For long plates, multiple lifting electromagnets can be arranged on a beam or spreader. The magnetic field can be adjusted to suit the confirmed lifting condition. This configuration supports controlled plate separation and transfer without mechanical gripping of the workpiece.

Representative MW84 Series Models

The following values are transcribed from the supplied product data sheets. Dimensions are overall body dimensions in millimetres. Confirm final model selection and lifting capacity against the actual plate grade, thickness, surface condition, plate length, and magnet quantity.

Important:The table is dimensional and electrical reference data, not a rated lifting-capacity table. Actual safe lifting capacity must be confirmed for the specific plate and operating arrangement.

A lifting electromagnet is not selected by magnet size alone. The available holding force changes with the air gap between magnet and plate, plate thickness, flatness, steel condition, temperature, and the number and position of magnets. Scale, paint, rust, oil, and distortion can reduce effective contact and must be considered before selecting the lifting arrangement.

For long plate handling, a multi-magnet lifting beam distributes support points along the load. The beam layout should limit plate deflection and keep each magnet in effective contact during lifting, travelling, and lowering. The control system, cable routing, and emergency power arrangements must be matched to the crane duty and site safety procedure.

Single-Magnet Lifting

A single industrial lifting electromagnet can be applied where the plate geometry and confirmed lifting condition allow stable contact. This arrangement is generally considered for shorter plates or defined handling positions.

Multi-Magnet Lifting Beam

For long or flexible plate, multiple rectangular lifting electromagnets can be combined beneath a beam or spreader. The magnet count, centre spacing, beam geometry, and hook connection should be engineered as one lifting system rather than specified independently.

Adjustable Magnetic Field

Adjustable magnetic field control allows the lifting condition to be matched to the selected workpiece and operating procedure. It does not replace verification of the actual plate condition or confirmation of the permissible lifting capacity.

• Steel plate loading and unloading in stockyards
• Plate transfer at cutting, rolling, or fabrication lines
• Material handling in steel service centres
• Crane-fed plate movement in heavy manufacturing workshops
• Multi-point lifting of long steel plate with a dedicated lifting beam

The lifting electromagnet must be connected to a suitable crane electrical system and lifting structure. The following points require confirmation before commissioning:

1. Plate dimensions, thickness range, steel grade, surface condition, and maximum working temperature.
2. Required lifting quantity, handling cycle, travel path, and permissible plate deflection.
3. Magnet quantity, centre spacing, lifting beam structure, shackles or chains, and hook interface.
4. DC power supply, duty cycle, control circuit, cable protection, and emergency power or load-retention provisions required by the site.
5. Inspection procedure for the magnetic contact face, lifting lugs, chains, cables, insulation, and control functions.

Do not lift non-ferromagnetic material, bundled material, or plate with uncontrolled separation risk unless the lifting system has been specifically engineered and approved for that condition.

Keep the magnet contact surface clean and free from severe mechanical damage. Inspect lifting lugs, chain assemblies, power cables, connectors, and insulation at intervals defined by the site maintenance plan. Electrical checks should be carried out with the magnet isolated in accordance with site lockout procedures. Any reduction in lifting performance requires investigation before the equipment returns to service.

What material can an industrial lifting electromagnet handle?

This product is intended for ferromagnetic steel plate. It is not suitable for aluminium, copper, stainless steel grades without sufficient magnetic response, or other non-ferromagnetic materials.

What plate thickness can the MW84 lifting electromagnet handle?

The supplied source material states a typical medium-thickness steel plate range of 6-32 mm. Final selection must be based on actual plate dimensions, steel condition, required lifting quantity, and the engineered magnet arrangement.

Is DC 220 V required for all models?

The product sheets state DC 220 V as the rated supply voltage for the MW84 series. A specific note identifies MW84-9030T/1 as DC 110 V. Confirm the selected model and site power system before ordering.

Can several lifting electromagnets be used on one beam?

Yes. Multiple magnets can be arranged on a lifting beam for long steel plate. The number of magnets, spacing, beam design, and lifting capacity must be confirmed as one complete handling system.

Does adjustable magnetic field guarantee the same lifting capacity for every plate?

No. Holding performance is affected by plate thickness, contact condition, air gap, surface contamination, temperature, and plate geometry. Magnetic field adjustment must be used within the verified operating condition.

Is a high-temperature lifting electromagnet available?

The supplied product information states a high-temperature option for workpieces up to 700 C. The operating temperature, duty cycle, plate condition, cable system, and safety arrangement must be confirmed before selection.

What information is needed to select a steel plate lifting electromagnet?

Provide plate length, width, thickness, steel grade, temperature, surface condition, maximum plate quantity, required lifting cycle, crane data, and the preferred lifting beam arrangement. These inputs are required to determine a suitable magnet configuration and safe lifting capacity.

For a technically defined quotation, provide the plate drawing or dimensions, material description, thickness range, temperature, required lifting quantity, crane hook height, power supply, and operating duty. This allows the industrial lifting electromagnet, beam configuration, and control arrangement to be matched to the handling task.
