QL Type Electromagnetic Suspension Bridge Crane

The electromagnetic crane belongs to the bridge-type lifting equipment, mostly adopting a double-girder bridge structure, composed of core components such as the bridge frame, trolley traveling mechanism, lifting trolley with an integrated hoisting system, and an electromagnetic suspension system that can extend and rotate 360 degrees. Its load handling device is an electromagnetic disk (or a matching electromagnetic suspension), which uses the principle of electromagnetic induction to generate magnetic force for attaching ferromagnetic materials (such as steel, scrap iron, steel slag, etc.), achieving an automated workflow of "attachment - vertical lifting - horizontal transfer - power-off release.

Equipment Description

 

The electromagnetic crane belongs to the bridge-type lifting equipment, mostly adopting a double-girder bridge structure, composed of core components such as the bridge frame, trolley traveling mechanism, lifting trolley with an integrated hoisting system, and an electromagnetic suspension system that can extend and rotate 360 degrees. Its lifting device is an electromagnetic disk (or matched with an electromagnetic suspension), which generates magnetic force through electromagnetic induction principles to attract ferromagnetic materials (such as steel, scrap steel, steel slag, etc.), achieving an automated workflow of "attraction - vertical lifting - horizontal transfer - power-off release".

The electrical control system integrates PLC control and variable frequency speed regulation technology, supporting centralized operation from the cab or remote wireless control. Some models are equipped with intelligent detection modules (such as residual magnetism detection of the disk, real-time current/voltage monitoring, fault warnings, etc.), ensuring operational precision and safety.

Application Fields

 

Widely serving industries such as metallurgy, mechanical manufacturing, shipbuilding, and scrap recycling, it is used for lifting operations of ferromagnetic materials. Typical scenarios include:

Steel plants: Workshop transfer and stacking of steel slag, steel coils, sections, and scrap steel;

Machinery factories: Hoisting and assembly of castings, large machine tool components, and metal molds;

Shipyards: Transport of hull sections and assembly of ship steel structures on the dock;

Scrap processing plants: Centralized grabbing, stacking, and transfer of loose scrap steel to crushing/smelting processes.

Product Advantages

 

High Efficiency, Labor-Saving

The electromagnetic attachment eliminates manual hooking/untying, enabling rapid "attraction-release" actions. Compared to traditional hook-type cranes, single-cycle operation time is reduced by over 30%, significantly improving material flow efficiency. It is particularly suitable for "hard-to-bundle" materials like loose scrap steel, reducing manual sorting costs.

Strong Adaptability, Covering Diverse Materials

The extendable + 360° rotatable electromagnetic suspension system flexibly handles ferromagnetic materials of different sizes (e.g., long steel slag, block scrap) and shapes. The adjustable magnetic force ensures stable lifting of single heavy items (e.g., hundred-ton steel coils) while efficiently grabbing loose scrap, covering all ferromagnetic materials from "bulk to scrap".

Safe and Reliable, Controllable Risks

Structural safety: The double-girder bridge design offers strong load capacity, suitable for large-tonnage (tens to hundreds of tons) material handling, meeting heavy industrial needs;

Lifting safety: The electromagnetic attachment combines multiple braking protections (dual brakes on hoisting mechanisms, anti-derail devices) with residual magnetism detection, overload protection, and power-loss magnetic retention (some models include backup battery power), ensuring stable lifting processes and preventing falling hazards.

High Intelligence, Precision Operation

Integrated with variable frequency speed regulation, 360° rotation, and suspension extension adjustment, combined with smart detection and remote control systems, it achieves millimeter-level precision positioning (e.g., steel slag charging, component assembly). It also supports remote operations in "unmanned workshop" scenarios, reducing worker exposure to high-risk environments (e.g., high-temperature smelting areas).

Durable Performance, Easy Maintenance

Core components (e.g., electromagnetic coil, hoisting motor) use high-temperature-resistant, wear-resistant materials and processes, adapting to harsh metallurgical conditions (high heat, dust). Modular structural design (e.g., quick-connect interfaces between suspension and disk) facilitates daily inspections and part replacements, lowering lifecycle maintenance costs.
