Efficient Material Handling: Powering Metal Fabrication Workshops

In metal fabrication, every process counts. From cutting to welding, each step demands precision and efficiency. However, one often overlooked aspect is material handling. How materials move within a workshop can significantly impact productivity and safety.

Enter double girder gantry cranes, the unsung heroes of material handling in metal fabrication. These robust machines are designed to tackle heavyduty tasks with ease, making them indispensable in any modern workshop.


 

Overview of Coil Handling Gantry Cranes

What are Double Girder Gantry Cranes?

Double girder gantry cranes are heavy duty lifting machines commonly found in industrial settings, including metal fabrication workshops. Unlike single girder gantry cranes, which have one beam spanning the gantry, double girder gantry cranes feature two parallel beams, or girders, running the length of the structure. These cranes typically operate on rails or tracks installed on the ground, allowing for smooth movement across the workspace.

Key Components:

• Girders: The primary loadbearing beams that support the hoist and trolley assembly.
• Hoist: The mechanism responsible for lifting and lowering loads.
• Trolley: The component that moves horizontally along the girders, enabling precise positioning of the load.
• End trucks: Structures mounted on the ends of the girders, supporting the trolley and facilitating movement along the rails.

Advantages Over Other Crane Types

So, why choose double girder gantry cranes over alternatives like overhead cranes or single girder gantry cranes? The answer lies in their superior strength, stability, and versatility.

• Strength: With two girders instead of one, double girder gantry cranes offer increased lifting capacity, making them ideal for handling heavy steel coils and other sizable loads commonly found in metal fabrication workshops.
• Stability: The dual girder design provides enhanced stability, reducing sway and ensuring precise control over the load, even when navigating tight spaces or lifting at significant heights.
• Versatility: Double girder gantry cranes are highly adaptable to various workshop layouts and operational requirements. They can be customized with additional features such as specialized lifting attachments or automation systems to further optimize performance.

Specific Features for Handling Heavy Steel Coils

When it comes to handling heavy steel coils, specific features are paramount for ensuring efficiency and safety.

• High Lifting Capacity: The robust construction of double girder gantry cranes enables them to lift steel coils weighing anywhere from 10 to 30 tons, meeting the demands of heavyduty metal fabrication operations.
• Precision Control: Advanced control systems allow operators to maneuver the crane with precision, ensuring smooth and accurate positioning of steel coils during loading, unloading, and transportation.
• Durability: Built to withstand the rigors of industrial environments, double girder gantry cranes are engineered for longevity, minimizing downtime and maintenance costs over their operational lifespan.

Applications in Metal Fabrication Workshops

Challenges of Handling HotRolled Steel Coils

Handling hotrolled steel coils presents unique challenges due to their high temperatures and inherent flexibility. These coils are often produced at temperatures exceeding 1700°F (927°C) and remain hot during transportation and storage. As a result, they are prone to deformation and damage if mishandled. Additionally, the radiant heat emitted by hot coils poses safety risks to workers and equipment.

Challenges of Handling ColdRolled Steel Coils

Coldrolled steel coils, while not subjected to the extreme temperatures of their hotrolled counterparts, present their own set of challenges. Coldrolled coils are processed at room temperature, resulting in a smoother surface finish and tighter dimensional tolerances compared to hotrolled coils. However, their increased hardness and susceptibility to surface damage require careful handling to prevent scratching or denting.

How Double Girder Gantry Cranes Address These Challenges Effectively

Double girder gantry cranes are uniquely suited to address the challenges associated with handling both hotrolled and coldrolled steel coils in metal fabrication workshops.

Precision Control:

• Double girder gantry cranes offer precise control over lifting, lowering, and positioning, minimizing the risk of damage to delicate coldrolled coils and ensuring the safe handling of hot coils.
• Advanced control systems allow operators to adjust lifting speeds and trolley movements with accuracy, enabling smooth and controlled material handling operations.

Enhanced Safety Features:

• Double girder gantry cranes are equipped with safety features such as overload protection, antisway systems, and emergency stop mechanisms to prevent accidents and protect both personnel and materials.
• Specialized heatresistant components and protective coatings help safeguard the crane from the radiant heat emitted by hot steel coils, ensuring reliable performance in hightemperature environments.

Customization Options:

• Double girder gantry cranes can be tailored to meet the specific requirements of handling hotrolled and coldrolled steel coils.
• Custom lifting attachments, such as coil hooks or Chooks, can be integrated to securely grip and transport coils of various sizes and weights, minimizing the risk of slippage or damage during handling.

By effectively addressing the challenges associated with handling hotrolled and coldrolled steel coils, double girder gantry cranes contribute to improved efficiency, safety, and productivity in metal fabrication workshops. In the next section, we'll explore the technical specifications and features that make these cranes indispensable tools for handling heavy materials.

 

Technical Specifications

Capacity Range (10 tons to 30 tons)

Double girder gantry cranes are available in a wide range of lifting capacities, typically ranging from 10 tons to 30 tons. This versatility allows them to handle various loads encountered in metal fabrication workshops, including heavy steel coils, machinery components, and structural elements.

Span and Lifting Height Requirements for Different Workshop Layouts

The span and lifting height of a double girder gantry crane are critical considerations that depend on the layout and dimensions of the workshop. The span refers to the distance between the outer edges of the crane's supporting legs, while the lifting height represents the maximum vertical distance the crane can raise a load. These specifications are determined based on factors such as the size of the workspace, the height of overhead obstructions, and the desired coverage area for material handling operations. Customization options are available to tailor the span and lifting height of the crane to suit specific workshop layouts and operational requirements.
