For managers and operators in steel mills and large-scale scrapyards, the material handling environment isn’t just challenging—it’s brutal. Relentless radiant heat from molten metal, abrasive dust, limited floor space, and the constant, heavy-duty cycle of lifting and moving ferrous scrap test every piece of equipment to its breaking point. Standard overhead cranes consistently fail here, leading to costly downtime, safety hazards, and inefficient operations.

Dongqi Crane delivers a definitive solution. Our specialized 5-20 ton electromagnetic overhead cranes are not merely adapted but are engineered from the ground up to conquer the extreme conditions of your facility. With integrated high-temperature protection and a space-saving roof-mounted design, this system is the key to unlocking new levels of productivity, safety, and reliability.

Core Advantages at a Glance

The Dongqi Electromagnetic Overhead Crane System is built on three foundational pillars designed to address your most critical pain points:

1. Advanced High-Temperature Resistance: Guarantees stable performance and extended service life in the most intense thermal environments.
2. Innovative Roof-Mounted Design: Maximizes valuable floor space by utilizing the overhead structure of your building, eliminating obstructive ground columns.
3. Seamless Electromechanical Integration: Features controls and structural elements optimized specifically for the rigorous demands of continuous electromagnetic lifting and cycling.

In-Depth Focus 1: High-Temperature Design – Built for the Inferno

We go far beyond basic specifications to ensure resilience where it matters most.

• Electrical System Fortification:
  • Class H Insulated Motors: The heart of the crane utilizes motors insulated with materials like glass fiber, silicone polymer, and Teflon, capable of withstanding temperatures up to 180°C (356°F). This drastically exceeds the limits of standard Class F (155°C) motors, preventing insulation breakdown and motor burnout.
  • Climate-Controlled Electrical Enclosures: Our proprietary electrical panels are equipped with high-capacity industrial air conditioners or cooling systems, robust insulation, and IP54+ sealing. This creates a protective “cool room” for sensitive components like Variable Frequency Drives (VFDs), PLCs, and contactors, shielding them from external heat and dust.
  • High-Temp Specialized Cabling: All cables, especially on the hoist and trolley, are sheathed in high-grade silicone rubber or other heat-resistant materials. This prevents the cracking, brittleness, and electrical failure common with standard PVC cables under thermal stress.
• Mechanical & Structural Enhancements:
  • Redundant Dual Braking System: Safety is non-negotiable. A primary and secondary (emergency) brake system ensures positive load control and failsafe stopping power, even in the event of a primary system malfunction.
  • High-Temp Anti-Corrosion Painting: We employ a multi-layer coating system starting with an zinc-rich epoxy primer for cathodic protection, followed by specially formulated heat-resistant topcoats. This system fights oxidation and rust, preserving the structural integrity and appearance of the crane.
  • Optional Heat Shields: For applications with extreme radiant heat (e.g., near furnaces), custom-mounted heat deflection shields can be added to protect critical components like the wire rope and drum.

In-Depth Focus 2: The Roof-Mounted Solution – Unlocking Your Floor Plan

Traditional floor-supported cranes create traffic obstacles and limit layout flexibility. Our roof-mounted system changes the game.

• Key Benefits:
  • Complete Floor Space Liberation: Remove all ground-based columns and runways. This allows for unobstructed movement of forklifts, trucks, and other equipment, and provides unlimited space for material staging directly beneath the crane’s coverage area.
  • Enhanced Safety: Eliminating floor columns removes a significant collision hazard for mobile equipment and personnel.
• Engineering & Installation Support:
  • Structural Integrity Assessment: A successful roof-mounted installation is contingent on the existing building structure’s ability to support the dynamic loads. Dongqi provides expert consultation and can work with your team to assess load-bearing capacity.
  • Custom Engineering: We design the crane runway beams and support system to integrate seamlessly with your building’s framework, whether it involves end trucks supported on runway beams or a underslung hanging configuration.
  • Precision Alignment: We emphasize the critical importance of perfectly aligned and level tracks to ensure smooth travel, prevent wheel wear, and eliminate erratic operation.

In-Depth Focus 3: Optimized for Electromagnetic Duty

This crane is more than a lift mechanism; it’s a complete magnetic material handling system.

• Integrated Control System: The crane comes with a built-in, isolated power supply and control system for the electromagnetic grapple or plate. This includes automatic cut-off and demagnetization cycles to ensure a clean, safe drop and prevent carried materials from falling during transit.
• Superior Structural Rigidity: The main bridge and end trucks are constructed with robust box-girder designs for minimal deflection under full load. This ensures precise spotting and control when handling scattered scrap, essential for efficiency and safety.
• Performance-Enhancing Options:
  • Variable Frequency Drive (VFD) Control: Upgrade to ultra-smooth acceleration and deceleration. This reduces swing load, enables pinpoint positioning, and drastically minimizes mechanical stress on the entire crane structure.
  • Radio Remote Control: Allows the operator to move freely to the safest and most optimal vantage point, away from heat, dust, and potential danger zones.

Application Scenarios: Where Dongqi Delivers Value

• Scenario 1: Steel Mill Melt Shop. A Dongqi 16/5 ton high-temperature EOT crane, roof-mounted in the scrap bay, continuously charges buckets for the electric arc furnace, operating reliably amidst radiant heat and around-the-clock schedules.
• Scenario 2: Major Metal Scrapyard. A fleet of Dongqi 10 ton electromagnetic cranes with remote controls efficiently sort and load fragmented scrap into trailers, working 7/7 in an outdoor environment with minimal downtime.
