o Mold handling: Lifting and positioning heavy moulds used to cast molten steel.
o Coil storage and retrieval: Stacking and retrieval of finished steel coils in high-bay warehouses.

• Under-suspension overhead crane: An under-suspension overhead crane is suspended from the base of the building structure. They are ideal for areas with limited overhead runway space and are typically used for:

o Maintenance Tasks: Lift and transport heavy tools and equipment to perform repair and maintenance activities throughout the facility.
o Specific workstations: Provide dedicated lifting capabilities within a designated area, such as a processing station or inspection area.

• EOT Crane (Electric Overhead Crane): EOT cranes are powered by electricity, providing precise control and smooth operation. They are available in a variety of configurations, including overhead, top-running bridge and underslung, making them highly versatile to meet the needs of different steel mills.

• Electromagnetic Overhead Cranes: electromagnetic overhead cranes are equipped with powerful magnets specifically designed to handle black (ferrous) materials. They require no slings or hooks, allowing efficient and safe handling of scrap, slabs and coils. Magnetic cranes are particularly suitable for:

o Scrap processing: sorting and separating ferrous scrap from non-ferrous materials.
o Loading Furnace: Quickly and safely load scrap metal into the furnace for melting.

• Finished product handling: Top-running overhead cranes with high lifting capacity facilitate stacking and retrieval of finished steel coils in overhead storage facilities. Electromagnetic bridge cranes are also used for efficient coil handling.
• Maintenance and repair: Underslung bridge cranes provide dedicated lifting support for maintenance tasks throughout the plant. They assist in lifting and transporting heavy tools, equipment and replacement parts.

How to Choose the Best Steel Mill Crane for You?

Choosing the most suitable crane for your steel mill requires careful consideration of several factors:

1. Lifting capacity:
   • Lifting Capacity: This refers to the maximum weight that the crane can safely lift. Steel plants need cranes with a wide range of capabilities, from cranes that handle lighter scrap metal to behemoths that manipulate large ladles of molten metal.
   • Span: This is the horizontal distance covered by the main girder of the crane. Consider the size and layout of your facility and select a crane with a span sufficient to cover the designated work area.
2. Lifting environment:
   • Task Type: Determine the main tasks the crane will perform. Overhead cranes are ideal for general material handling while top-running overhead cranes excel in high-clearance applications. underslung cranes are suitable for designated work areas, while electromagnetic cranes are specifically designed to handle ferrous materials.
   • Temperature and environment: Steel plant environments are hot and dusty. Make sure the crane you choose is designed for such conditions and uses heat-resistant materials and encapsulated electrical components.
3. Working class:
   • Speed: Consider the speed required for lifting and travel movements. Faster cranes can improve overall productivity, but prioritize safety and stability over speed.
   • Control System: Modern cranes offer advanced control systems for precise positioning and smooth operation. Choose a system that matches the operator’s skill level and offers features that increase safety and productivity.
4. Automated control:
   The steel industry is increasingly adopting automation to improve efficiency and safety. If repetitive tasks are involved, such as scrap loading or coil handling, consider a crane with automation capabilities.

Optimizing Steel Mill Crane Operations

By carefully selecting the right crane type for your specific needs, you can significantly improve your steel plant’s efficiency, safety and productivity. Here are some additional considerations for optimizing crane operations:

• Conduct a thorough site assessment: Evaluate the facility’s layout, capacity requirements and environmental conditions before selecting a crane.
• Create a preventive maintenance plan: Regular maintenance ensures smooth operation, minimizes downtime and extends the life of your crane.
• Operator Training: Proper training equips operators with the skills needed to operate the crane safely and efficiently.
