Double Girder Overhead Crane With Electromagnet

The double girder overhead crane with electromagnet is a high-efficiency, heavy-duty lifting equipment designed for material handling scenarios that require quick, stable, and precise adsorption and transportation of ferrous materials. Integrating the advantages of a double girder structure and an electromagnetic adsorption system, this crane is widely used in factories, warehouses, ports, steel mills, and other industrial fields, significantly improving material handling efficiency and reducing labor intensity.

Product Structure & Core Advantages

1. Double Girder Bridge Structure

The crane adopts a high-strength double girder bridge design, made of Q235B or Q355B steel plate through precise cutting, welding, and shot blasting treatment. This structure ensures excellent load-bearing capacity, rigidity, and stability, effectively avoiding deformation during long-term heavy-load operation. The span of the double girder can be customized from 10m to 35m, and the lifting height ranges from 6m to 30m, adapting to different workshop spaces and operation requirements. The bridge is equipped with high-quality running mechanisms, including driving motors, reducers, and brakes, which realize smooth and low-noise movement along the track, with stable operation and low failure rate.

2. Electromagnetic Adsorption System

The core component of the crane is the high-performance electromagnet, which is specially designed for adsorbing ferrous materials such as steel plates, steel bars, scrap steel, and castings. The electromagnet is made of high-quality copper wire and silicon steel sheet, with reasonable coil design and high magnetic permeability, ensuring strong adsorption force and uniform magnetic field distribution. The adsorption capacity can be customized according to customer needs, ranging from 0.5t to 50t, effectively preventing materials from falling during transportation and ensuring operation safety.

The electromagnetic system is equipped with a reliable power supply and control device, including a rectifier, a voltage stabilizer, and an emergency power-off switch. In case of sudden power failure, the emergency power supply will automatically start, maintaining the magnetic force of the electromagnet for a certain period of time, preventing materials from falling and avoiding safety accidents. In addition, the electromagnet is equipped with a protective cover, which can effectively prevent dust, water, and other impurities from entering, extending its service life.

3. Control System

The crane is equipped with an advanced control system, which can be selected as a ground control (button station), remote control, or cab control according to customer needs. The remote control adopts a wireless frequency hopping technology, with a control distance of up to 50m, flexible operation, and no dead angle, allowing operators to stand in a safe position to control the crane. The cab is designed with a comfortable seat, a clear operation panel, and a wide field of vision, reducing operator fatigue during long-term operation. The control system has perfect protection functions, including overload protection, overcurrent protection, voltage loss protection, and limit protection, ensuring the safe and stable operation of the crane.

Technical Parameters

Application Scenarios

The double girder overhead crane with electromagnet is mainly used for the handling of ferrous materials in various industrial fields, and its specific application scenarios include:

• 1. Steel Mills: Handling steel plates, steel bars, steel billets, and scrap steel in smelting, rolling, and finishing workshops.
• 2. Warehouses & Logistics Centers: Loading, unloading, and stacking ferrous materials such as steel coils, castings, and mechanical parts.
• 3. Ports & Terminals: Unloading ferrous cargo from ships and loading it onto trucks or trains, improving the efficiency of cargo handling.

• 5. Scrap Recycling Plants: Adsorbing and transporting scrap iron, scrap steel, and other recyclable ferrous materials, realizing efficient sorting and recycling.

Safety & Maintenance

Safety Features

Safety is the core of our product design. The double girder overhead crane with electromagnet is equipped with multiple safety protection devices to ensure the safety of operators, equipment, and materials:

• 1. Overload Protection: When the lifting load exceeds the rated capacity, the overload limiter will automatically alarm and cut off the lifting power supply, preventing equipment damage and accidents.
• 2. Power Failure Protection: Equipped with an emergency power supply, which can maintain the magnetic force of the electromagnet for 10-30 minutes after power failure, avoiding material falling.
• 3. Limit Protection: Lifting height limit and running stroke limit devices are installed to prevent the crane from exceeding the safe operation range.
• 4. Emergency Stop Button: Emergency stop buttons are installed on the control panel, remote control, and cab, which can quickly cut off the power supply in case of emergency.
• 5. Anti-collision Device: Anti-collision sensors are installed on the bridge and trolley to prevent collisions between cranes or between the crane and other equipment.

Maintenance Tips

Regular maintenance can effectively extend the service life of the crane and ensure its stable operation. The main maintenance items include:

• 1. Regularly check the electromagnet for damage, loose wires, and magnetic force attenuation, and clean the surface of the electromagnet to remove dust and rust.
• 2. Check the lubrication of the running mechanism (motors, reducers, bearings) regularly, and add lubricating oil or grease in a timely manner to reduce wear.
• 3. Inspect the steel structure of the bridge and trolley for deformation, cracks, and loose bolts, and repair or replace them in a timely manner.
• 4. Check the control system and safety protection devices regularly to ensure their normal operation, and calibrate the overload limiter and limit switch regularly.
• 5. Keep the crane clean, avoid dust and corrosive substances from accumulating on the equipment, and store it in a dry and ventilated place when not in use for a long time.
