INTRODUCTION

What is this?

The magnet double girder overhead crane is a double girder bridge crane equipped with an electromagnetic chuck as the lifting attachment. Through magnetizing and demagnetizing the electromagnetic chuck, it achieves fast picking, transferring, and loading/unloading of ferromagnetic materials such as steel plates, steel ingots, scrap steel, and steel sections. If you are managing a steel processing plant, scrap recycling yard, shipyard, or steel stockyard, and need to efficiently handle ferromagnetic materials without using hooks or slings, this product is designed for you.

Why choose a magnet crane over a standard hook crane?

Compared to standard hook cranes, the magnet crane offers five core advantages:

First, higher operational efficiency – one-button magnetizing and demagnetizing of the electromagnetic chuck eliminates manual hooking and unhooking, reducing each lifting cycle time by over 50%.

Second, wider material applicability – handles steel plates, steel coils, steel ingots, scrap steel, steel rails, sections, and various other ferromagnetic materials, one machine for multiple uses.

Third, safe with power failure protection – standard backup battery system maintains magnetism for 10-30 minutes after main power failure, ensuring materials do not fall.

Fourth, adjustable lifting force – electromagnetic force can be adjusted according to material weight and shape for gentle handling, avoiding surface damage.

Fifth, intelligent monitoring – the cabin is equipped with a magnet control system displaying real-time voltage, current, and chuck temperature, with automatic fault alarm.

Enhance ferromagnetic material handling efficiency with the power of electromagnetism.

What can we do for you?

We understand that every customer has different material shapes, different capacities, and different working environments. Therefore, we offer flexible customization options: lifting capacity from 5 tons to 50 tons; electromagnetic chuck types of circular (for scrap steel/ingots) or rectangular (for steel plates/sections); control options of cabin or remote radio; standard VVVF speed control. Whether your material is whole steel plates or loose scrap steel, we can match the most suitable magnet type and lifting capacity.

Unsure? Don't know?

Not sure whether to choose a circular or rectangular chuck? Don't know how much magnetic force is needed to lift your material? No problem. Just tell us: your material type (steel plate, scrap steel, steel ingot, etc.), material dimensions and single piece weight, and your workload per shift. Our engineers will provide you with an accurate quote and CAD drawings within 24 hours. Click the button below or contact us via WhatsApp/email to get your customized solution.

💡 Tip: We offer free selection consulting. Even if you are unsure about specific parameters, feel free to describe your material types and handling needs, and we will calculate for you.

APPLICATION SCENARIO

[1] Power Plants – Grabbing and feeding coal to boilers; handling bottom ash and biomass fuel.

[2] Ports and Freight Terminals – Loading and unloading bulk cargo such as coal, grain, ore, and fertilizers from ships or trucks.

[3] Mines and Steel Mills – Handling ore, mineral powder, coke, scrap steel, and slag in harsh environments.

[4] Cement and Building Materials Plants – Moving limestone, clay, clinker, and aggregates for production lines.

[5] Grain Depots and Food Processing – Grain intake, silo turnover, and raw material stacking in flour mills and feed plants.

ADVANTAGES

[1] High Efficiency for Bulk Materials – Automatic grab operation eliminates manual shoveling, greatly improving handling speed.

[2] Compact and Low Headroom – Single girder design reduces crane height, suitable for workshops with limited space.

[3] Light Self-weight & Energy Saving – Lower dead weight reduces building load and power consumption.

[4] Flexible Grab Options – Shell grab for fine materials, motor grab for large lumps, and custom grabs for special applications.

[5] Easy Maintenance – Simple structure and modular components allow quick inspection and low failure rate.
