For steel service centers, scrap processing yards, and heavy manufacturing plants, the handling of ferrous materials is not just a task—it is the core of your operation. Efficiency, safety, and versatility directly impact your bottom line. When a single crane must seamlessly transition from lifting a massive 32-tonne steel coil to precisely positioning a 5-tonne bundle of rebars, standard equipment falls short. This is a challenge of precision, power, and operational agility.

Dongqi Crane presents the engineered solution: our CE-Certified Main Hanger Electromagnetic Overhead Crane. Specifically designed with a main and auxiliary hoist system (16/3.2t to 32/5t capacity), this crane is the ultimate tool for facilities that demand both heavy-duty lifting power and intelligent, flexible material handling. It transforms your steel yard or production floor into a model of streamlined productivity and safety.

The Operational Imperative: Why a “Main Hanger” Design is a Game-Changer

In demanding industrial environments, not all lifts are created equal. The traditional single-hook crane forces a compromise. Our Main Hanger design eliminates this by providing two distinct but integrated lifting tools on one crane:

• Main Hoist (16t to 32t): This is your powerhouse. It is engineered for the heaviest, most critical lifts—large steel coils, heavy plate stacks, or substantial machinery. It handles the primary workload with robust durability.
• Auxiliary Hoist (3.2t to 5t): This is your agility partner. Designed for lighter, faster, and more frequent lifts, it is perfect for handling smaller bundles, tools, or for precise positioning work. Its higher speed increases cycle times for smaller loads.

The Strategic Advantage: This dual-capacity system allows your operators to select the perfect tool for every job without compromise. You avoid the inefficiency of using a massive 32t hook to lift a 2t load, saving energy and reducing wear. More importantly, it enables concurrent or rapid-sequencing tasks, dramatically improving workflow fluidity.

The Heart of the System: Advanced Electromagnetic Handling

At the core of this crane’s capability is its electromagnetic lifter system, designed for secure, efficient, and damage-free handling of ferrous materials.

• Superior Magnetic Force: Utilizing high-grade, energy-efficient electromagnets, we ensure a secure grip on everything from irregular scrap to finished steel plates. Our systems are designed to provide a strong safety factor, accounting for material permeability and surface conditions.
• Intelligent Control & Safety: The electromagnetic system features automatic current regulation for consistent holding power and failsafe backup systems. In the unlikely event of a power interruption, advanced battery back-up units (available as an option) can engage to safely retain the load and allow for controlled lowering.
• Minimized Damage: Compared to hooks, slings, or grabs, electromagnetic lifting spreads the holding force evenly, eliminating pressure points that can damage expensive finished products like coated coils or precision-cut plates.

Dongqi Engineering: Built for Reliability in the Toughest Conditions

Our cranes are more than a collection of parts; they are integrated systems engineered for performance.

1. Robust Double Girder Structure: Provides exceptional hook height, superior stability against side loads (critical for magnet work), and long-term structural integrity, even under A6/A7 duty cycles.
2. Precision Control with VFD: Variable Frequency Drives on all motions ensure smooth acceleration and deceleration. This is vital for preventing load swing when carrying steel under a magnet, allowing for pinpoint placement and enhanced safety.
3. Comprehensive Safety Ecosystem: As a CE-certified manufacturer, safety is inherent in our design. The crane includes overload limiters, dual-end travel limits, anti-collision systems, and emergency stop circuits, all compliant with EN 15011 and other relevant standards.

The Tangible Value of CE Certification: Your Assurance of Excellence

The CE mark on your Dongqi crane is a direct investment in risk mitigation and operational confidence. It certifies that the crane meets all essential health, safety, and environmental protection requirements of the European Economic Area. This means:

• Verified Design Integrity: The design has been assessed for all foreseeable hazards.
• Reduced Liability & Downtime: Compliance minimizes the risk of accidents and regulatory non-conformance issues.
• Global Market Acceptance: CE certification is a globally recognized benchmark of quality and safety, facilitating smoother project approvals.
• Complete Documentation: You receive a full technical construction file, including risk assessment, declarations of conformity, and detailed manuals for safe operation and maintenance.
