Streamline Heavy Lifting Operations with Dongqi’s CE-Certified Main & Auxiliary Hook Electromagnetic Cranes (16/3.2t to 32/5t)

For operations that regularly handle large quantities of ferrous materials—be it in a steel mill, a heavy machinery fabrication plant, or a bustling scrap yard—efficiency and safety in lifting are non-negotiable. The challenge often lies in managing tasks that require both massive strength for heavy lifts and nimble precision for smaller, more intricate placements. Using a single-hook crane for diverse tasks creates inefficiency, while coordinating multiple pieces of equipment is costly and complex.

Dongqi Crane provides a singular, intelligent solution to this dual demand. Our CE-Certified Main & Auxiliary Hook Electromagnetic Overhead Crane is engineered specifically for environments where powerful lifting capacity must coexist with operational flexibility. With a robust main hook (16t to 32t) for your heaviest loads and a precise auxiliary hook (3.2t to 5t) for lighter tasks, all integrated with a high-performance electromagnetic lifting device, this crane consolidates multiple handling functions into one reliable, safe, and powerful system.

The Operational Challenge: Bridging the Gap Between Power and Precision

Handling steel plates, coils, structurals, or heavy scrap involves a variety of tasks:

1. Heavy Bulk Lifting: Moving multi-ton steel coils from storage to a processing line.
2. Precision Positioning: Carefully setting a fabricated beam into place on an assembly.
3. Rapid Material Transfer: Quickly moving batches of smaller steel parts or scrap.

A standard single-capacity crane forces a compromise—it’s either overpowered and clumsy for small tasks or completely incapable of large ones. This leads to workflow bottlenecks, underutilized assets, and potential safety risks from improper equipment use. Our dual-hook electromagnetic crane is designed to eliminate these compromises entirely.

The Dongqi Solution: A Dual-Hook System Engineered for Superior Performance

This crane is built around a flexible and powerful architecture that adapts to your workload, not the other way around.

1. Optimized Dual-Hook Configuration: Power Meets Finesse

• High-Capacity Main Hook (16t-32t): Designed for your most demanding lifts. Its robust construction and powerful hoist mechanism are built for durability under heavy, continuous use, typically rated for Duty Class A6/A7.
• Precision Auxiliary Hook (3.2t-5t): Operates at a higher speed and offers finer control, perfect for lighter loads, detailed positioning, and maintenance work. This hook can work independently, allowing smaller tasks to proceed without tying up the main hoist.

2. Core of Efficiency: The Advanced Electromagnetic Lifter

The integrated electromagnetic lifter is the heart of this system, transforming the crane into a highly efficient material handling tool for ferrous items.

• Instant Attachment & Release: The electromagnet provides immediate contact and release of loads without the need for slings, hooks, or manual securing. This drastically reduces cycle times compared to traditional rigging methods.
• Safe and Secure Hold: Powered by a dedicated, rectified DC power supply system, the magnet delivers a consistent and powerful magnetic field, ensuring load security during transport.
• Handling Versatility: It can efficiently lift a single large object (like a steel plate) or a collection of smaller items (like scrap or parts), offering unparalleled flexibility.

3. Intelligent Control and Safety Synergy

The crane’s control system is designed for intuitive operation and maximum safety.

• Dual Independent Controls: Operators can seamlessly switch between main and auxiliary hooks, and engage/disengage the electromagnet, all from a single pendant station or via optional radio remote control.
• Integrated Safety Logic: The system includes interlocking to prevent simultaneous operation of both hooks on a single task unless specifically configured, along with automatic warning systems for magnet power status.
• Smooth & Precise Movement: Variable Frequency Drives (VFDs) are applied to all motions (bridge travel, trolley travel, hoisting), ensuring smooth acceleration and deceleration. This is critical for preventing load swing on the magnet—a key factor in operational safety and precision.

The Assurance of CE Certification: Built to the Highest Standards

The CE mark on this crane is your guarantee that it complies with the strict health, safety, and environmental protection requirements of the European Union. This certification, adhering to the Machinery Directive (2006/42/EC), means:

• Full Compliance: Guaranteed acceptance for operation in EU markets and other regions that recognize CE standards.
• Verified Safety: The design has undergone rigorous risk assessment. Critical safety features—such as dual braking systems, overload limiters, emergency stops, and travel limit switches—are not optional; they are integral and certified.
• Quality Assurance: Certification mandates a controlled, documented manufacturing process (ISO 9001 underpins our production), ensuring you receive a reliable and well-documented product.
