New and Used Double Girder Bridge Cranes: Find the Perfect Fit for Your Business

Double girder bridge cranes are essential tools in industries that require heavy lifting, precise load control, and efficient material handling. These cranes are characterized by their dual-girder design, which offers superior strength and stability compared to single-girder cranes, making them ideal for handling heavier loads and larger spans. Whether you're considering investing in a new crane or exploring the benefits of purchasing a used one, it's important to understand the key features, advantages, and considerations that will help you find the perfect double girder bridge crane for your business.

What Is a Double Girder Bridge Crane?

A double girder bridge crane consists of two parallel girders that form the main structure, supported by end trucks that move along a set of rails. The hoist mechanism is mounted on top of the two girders, allowing for more efficient use of vertical space and greater lifting capacity. This type of crane is ideal for applications that require heavy-duty lifting, longer spans, or higher lifting heights.

Key components of a double girder bridge crane include:

• Bridge: The two parallel girders that form the primary load-bearing structure.
• End trucks: Units at each end of the bridge that move along the runway rails.
• Hoist: The mechanism that lifts and lowers the load, which can be mounted on top of or between the girders.
• Trolley: The component that moves the hoist along the length of the bridge, enabling horizontal load movement.

Advantages of Double Girder Bridge Cranes

Double girder bridge cranes offer several advantages that make them an attractive option for various industries, especially those requiring heavy lifting or large spans. These benefits include:

• Higher Lifting Capacity
  One of the main advantages of a double girder design is its ability to handle heavier loads. While single girder cranes typically handle lighter loads, double girder bridge cranes can lift capacities ranging from 10 tons to over 100 tons, making them ideal for industries like steel production, shipbuilding, and heavy machinery manufacturing.
• Greater Lift Height
  The hoist in a double girder bridge crane is usually mounted on top of the girders, providing maximum vertical lift height. This is particularly beneficial in environments with limited headroom, as it allows for more efficient use of space and improved clearance for moving materials.
• Longer Spans
  Double girder bridge cranes are better suited for larger workspaces with long spans, as the two-girder design offers increased strength and stability over longer distances. This makes them an excellent choice for large warehouses, factories, and assembly plants.
• Durability and Reliability
  The robust construction of double girder bridge cranes ensures they can withstand heavy-duty use in demanding industrial environments. Their design offers enhanced durability, which leads to longer service life and lower maintenance costs over time.

New vs. Used Double Girder Bridge Cranes

When investing in a double girder bridge crane, you have the option of purchasing either a new or used crane. Both options have their own advantages, and the choice will depend on your business needs, budget, and long-term goals.

• New Double Girder Bridge Cranes
  Buying a new crane offers the benefit of customization and the latest technology. New cranes come equipped with advanced features like automation, remote control, anti-sway technology, and improved safety systems. Additionally, new cranes come with warranties and customer support, giving you peace of mind and minimizing the risk of breakdowns in the early stages of use.
• Another key advantage is the ability to customize a new crane to meet your specific requirements. You can work with the manufacturer to choose the exact lifting capacity, span, hoist type, and control system that best suits your operational needs.
• However, new cranes often come with a higher upfront cost, which may not be suitable for businesses with limited capital or urgent equipment needs.
• Used Double Girder Bridge Cranes
  For businesses looking to save on initial investment costs, purchasing a used double girder bridge crane can be a smart option. Used cranes can offer significant savings compared to new models, allowing businesses to acquire high-capacity lifting equipment at a fraction of the price. This is particularly beneficial for smaller companies or those operating on tight budgets.
• However, when buying a used crane, it’s important to ensure that the equipment has been properly maintained and is in good working condition. You should thoroughly inspect the crane or purchase from a reputable supplier that offers certified, pre-owned cranes. Additionally, consider the availability of spare parts and technical support, as older models may be harder to maintain if replacement parts are difficult to find.

Aicrane offers various types of overhead cranes to meet different requirements and you can contact Aicrane group to know further about crane machines and choose a right one for your lifting needs.

Key Considerations for Choosing the Right Crane

When selecting a new or used double girder bridge crane, several factors should be considered to ensure you choose the right equipment for your business:

• Lifting Capacity
  Determine the maximum weight you will need to lift regularly. Double girder cranes are suitable for heavier loads, but selecting a crane with the appropriate capacity for your operations is crucial to avoid overloading and ensure safe operation.
• Span and Height Requirements
  Consider the width of your workspace and the required lifting height. Double girder bridge cranes are designed for longer spans, so make sure the crane can cover the entire area where lifting operations will take place.
• Operational Environment
  The environment in which the crane will operate plays a significant role in the decision-making process. For instance, harsh environments like steel mills or outdoor settings may require additional corrosion resistance or weatherproofing. Temperature extremes, dust, and moisture should also be considered when selecting the right crane.
• Safety and Compliance
  Ensure that the crane complies with industry safety standards, such as OSHA, ASME, and ISO regulations. Whether new or used, the crane should have modern safety features, including overload protection, emergency stop systems, and proper load control mechanisms.
• Maintenance and Serviceability
  Whether buying new or used, it’s important to consider the availability of maintenance services and spare parts. Regular inspections and maintenance are essential for keeping your crane in peak operating condition and extending its service life.

Double girder bridge cranes offer a powerful and reliable solution for handling heavy loads in industrial settings. Whether you opt for a new crane with customizable features and the latest technology or choose a cost-effective used crane, it's essential to evaluate your specific lifting requirements and operational environment. By understanding the advantages and key considerations associated with double girder bridge cranes, you can make an informed decision that ensures long-term value and efficiency for your business.
