Double Girder Electromagnetic Overhead Travelling Crane

Product Description

The double girder electromagnetic overhead travelling crane is a heavy-duty material handling device that combines a rigid double girder bridge with a high-efficiency electromagnetic suction cup. It is designed specifically for applications requiring automated grasping, handling, and stacking, such as steel mills, profile processing, scrap processing, docks, and large warehouses. This equipment combines high suction force with stable operation, supports intelligent control and production line integration, significantly improving loading and unloading efficiency while reducing manual risks and secondary material damage.

Core Advantages of the Electromagnetic Overhead Travelling Crane

  ● It features a high-performance electromagnetic suction cup with strong suction force, flexible suction and release control, and safety features such as power-off hold and power-off release.

  ● The double girder structure increases span and load capacity while reducing deflection, making it suitable for medium- to long-span applications and heavy loads.

  ● Optimized electromagnetic coils and heat dissipation systems, along with optional energy-saving modules, result in low operating energy consumption. The modular design facilitates maintenance and spare parts replacement.

  ● Designed specifically for magnetic materials, it is an irreplaceable specialized lifting equipment for industries such as steel and metallurgy.

  ● The suction cup specifications, bridge span, lifting height, and control logic can all be customized to meet customer requirements.

Structure and Operating Principle of an Electromagnetic Overhead Crane

  ● Metal Structure: Primarily composed of the bridge (including the main beam and end beams) and the trolley frame. The entire structure is welded from high-strength steel, offering excellent mechanical properties and ensuring stability and long life under heavy loads and high-frequency operation.

  ● Hoisting and Operating Mechanism: Comprises the hoisting motor, reducer, reel, brake, and wire rope. It drives the electromagnetic chuck vertically, ensuring smooth lifting and precise positioning.

  ● Electromagnetic Chuck System: Consists of the electromagnetic chuck body, control cabinet, cable reel (for retracting and extending the power cable), and demagnetizer. During operation, the control cabinet supplies direct current to the electromagnetic chuck, generating a strong magnetic field that firmly holds the material. Upon power failure, the magnetic field dissipates, releasing the material.

  ● Electrical Control System: Utilizing variable frequency speed regulation technology, the crane hoisting and trolley operations achieve smooth starting and stopping, effectively preventing load sway and ensuring precise and safe operation.
