Rotary Beam Spreader with Magnets for Long Steel Plate & Rebar Handling
Short Video Description
This video shows a rotary beam spreader with magnets designed for lifting and handling long and large steel plates, steel sheets, bars and rebar bundles. The magnetic spreader beam combines a rigid lifting beam with multiple electromagnetic lifting magnets to distribute the load along the length of the material.
A magnetic spreader beam, also called a spreader beam with magnets or magnetic lifting beam, is useful when a long steel load cannot be safely handled from a single lifting point. Multiple magnetic lifting points can provide better load distribution and help reduce load bending during lifting.
The rotary beam spreader can be designed with a rotating or adjustable lifting arrangement according to the required load orientation and handling process. It can be used with overhead cranes, gantry cranes, mobile lifting equipment and other suitable lifting machines.
For large steel plates and long steel products, Yuantai engineers consider the load length, load weight, material thickness, magnet arrangement, lifting points, beam deflection, center of gravity and required rotation angle before selecting the final spreader beam design.

What Is a Rotary Magnetic Spreader Beam?
A rotary magnetic spreader beam is a lifting beam equipped with multiple electromagnetic magnets and a rotating or adjustable lifting arrangement. It is designed to pick up long or large ferrous loads while distributing the lifting force across several points.
Compared with lifting a long steel plate or rebar bundle from one or two points, a magnetic lifting beam can position the lifting force closer to the load's actual center of gravity and along its length.
This makes the system useful for handling long steel products where load stability, deformation control and balanced lifting are important.
Why Use a Spreader Beam with Magnets for Long Steel?
Long steel plates, sheets and rebar bundles can be difficult to handle with a conventional hook and sling arrangement. A spreader beam with magnets provides multiple lifting points along the load.
- Distributes lifting force over a longer load area
- Reduces concentrated lifting points
- Helps maintain load balance during lifting
- Suitable for long and large steel plates
- Suitable for steel sheets and profiles
- Can handle certain rebar bundles and long steel products
- Magnet positions can be customized for different load dimensions
- Can be integrated with overhead and gantry cranes
Rotary Spreader Beam for Steel Plate and Sheet Handling
For large steel plate lifting, the spreader beam should be designed according to the plate length, width, thickness and weight. Multiple electromagnetic magnets can be arranged along the beam to provide more balanced lifting.
The magnet spacing is important because the lifting points influence the plate's bending behavior and stability. Yuantai engineers therefore calculate the beam structure, magnet position and lifting points together rather than selecting magnet locations only according to visual spacing.
For thin or flexible steel sheets, additional attention is required because the material may deform when lifted. The final magnet configuration should therefore be based on the actual plate specification.
Magnetic Spreader Beam for Rebar Bundle Handling
A magnetic lifting beam for rebar bundles can be used for handling suitable ferrous steel bundles in storage yards, fabrication plants and construction material facilities.
The magnet configuration should match the bundle diameter, length, weight and surface condition. Bundled material must also be assessed for stability because the magnetic lifting force depends on the actual contact condition between the magnet and the steel.
For long rebar bundles, multiple lifting magnets along the spreader beam can help distribute the lifting points and reduce excessive bending of the bundle.
Key Design Factors for a Rotary Magnetic Spreader Beam
| Design Factor | Effect on Spreader Beam Design |
|---|---|
| Load weight | Determines the required beam and total magnetic lifting capacity. |
| Load length | Determines beam length and required magnet distribution. |
| Load width | Affects magnet contact area and load stability. |
| Steel thickness | Influences the effective magnetic lifting force. |
| Magnet capacity | Must be matched to the actual steel material and lifting conditions. |
| Magnet spacing | Controls load distribution and affects bending and deformation. |
| Center of gravity | Determines the correct lifting-point arrangement and balance. |
| Beam deflection | Must remain within the required structural limits during lifting. |
| Rotation requirement | Determines the required rotary mechanism and lifting configuration. |
| Working frequency | Affects structural duty and electromagnetic system selection. |
How Does a Rotary Beam Spreader Improve Long Steel Handling?
The main advantage of a rotary beam spreader with magnets is the ability to distribute lifting force across multiple points while providing controlled orientation of the load.
For long steel plates, the beam can support several magnetic lifting points along the plate. This helps maintain a more balanced load position during lifting and transportation.
The rotary function can also help when the steel product must be reoriented between pickup, storage, processing or loading positions. The required rotation mechanism should be selected according to the load geometry and operating process.
Rotary Magnetic Spreader Beam vs Conventional Lifting Slings
| Item | Rotary Magnetic Spreader Beam | Conventional Slings |
|---|---|---|
| Lifting method | Multiple electromagnetic lifting points | Hooks, wire rope slings or synthetic slings |
| Long steel handling | Well suited to long ferrous products | Suitable with correctly selected sling arrangement |
| Load distribution | Multiple adjustable lifting points | Depends on sling configuration |
| Loading efficiency | Fast magnetic pickup and release | Requires sling positioning and attachment |
| Load rotation | Rotary mechanism can be integrated | Requires suitable rigging and lifting procedure |
| Best application | Repeated steel plate, sheet and long steel handling | General lifting of various load types |
How Yuantai Designs a Magnetic Lifting Spreader Beam
Yuantai engineers design the magnetic spreader beam according to the actual steel product instead of using one standard magnet arrangement for every load.
- Confirm maximum load weight
- Confirm steel plate, sheet or rebar dimensions
- Determine load center of gravity
- Select the appropriate electromagnetic magnets
- Calculate magnet quantity and spacing
- Check spreader beam strength and deflection
- Design the rotary mechanism when rotation is required
- Check lifting points and crane connection
- Configure magnet power and control system
- Review emergency magnet protection requirements
This engineering approach helps the magnetic lifting beam match the actual load rather than relying only on the rated crane capacity.
