Gantry crane
Weiyuan A-Type Double Girder Gantry Crane
Product Overview
The Weiyuan A-Type Double Girder Gantry Crane is the ultimate solution for heavy-duty lifting in demanding outdoor and large-scale industrial environments. Engineered for maximum strength, stability, and lifting capacity, this crane combines a robust A-frame structure with a powerful double-girder design. This configuration provides superior performance for handling immense loads such as shipping containers, large precast concrete sections, and heavy machinery. With customizable capacities reaching 50 tons and beyond, the Weiyuan double girder gantry crane is the powerhouse your operation needs for unmatched productivity and reliability.
Product Advantages
Exceptional Strength and Stability
The dual-girder design, supported by a sturdy A-frame, offers unparalleled structural integrity and load stability. This robust construction allows for higher lifting capacities and wider spans, making it the perfect choice for the most challenging lifting tasks without compromising on safety.
Higher Lifting Height and Hook Clearance
By running the hoist trolley on top of the two main girders, this design naturally maximizes the lifting height. This provides excellent clearance under the hook, allowing you to lift taller objects and stack materials higher, making the most of your operational space.
Heavy-Duty Performance and Durability
Built to withstand the toughest conditions, this crane is constructed from high-tensile steel and features advanced welding techniques. A comprehensive anti-corrosion paint system ensures it can operate reliably for years in harsh outdoor environments like ports, rail yards, and industrial plants.
Advanced Control and High Efficiency
Equipped with a high-performance hoist and options for cabin control or wireless remote, operators can manage heavy loads with precision and confidence. Optional VFD (Variable Frequency Drive) controls provide smooth acceleration and deceleration, reducing load sway and improving positioning accuracy for greater efficiency.
Full Customization for Heavy Industry
Weiyuan specializes in tailoring these powerful cranes to your exact needs. We can customize the lifting capacity, span, height, cantilever lengths, and control systems to create a purpose-built solution that integrates seamlessly into your workflow.
Application Scenarios
- Ports and Container Terminals: The premier choice for loading, unloading, and stacking ISO shipping containers with speed and precision. Cantilever options allow for extended reach over vessels and truck lanes.
- Precast Concrete and Construction Yards: Effortlessly handles massive precast concrete beams, bridge segments, and other large construction components.
- Steel Mills and Fabrication Plants: Ideal for moving heavy steel coils, plates, and large fabricated structures within stockyards and production areas.
- Railway Freight Yards: Provides powerful lifting capabilities for transferring heavy goods and containers between railcars and trucks.

FAQ
Q: What is the main difference between a single girder and a double girder gantry crane?
A: A double girder gantry crane uses two main beams, which provides greater strength and stability. This allows for much higher lifting capacities, wider spans, and faster travel speeds compared to a single girder crane, making it suitable for heavy-duty industrial applications.
Q: What is a cantilever and do I need one?
A: A cantilever is an extension of the main girders that projects beyond the support legs. It is extremely useful in ports and yards as it allows the crane to reach over areas to lift loads without the legs getting in the way, such as over the side of a ship or a railway line.
Q: Is cabin control or remote control better for this type of crane?
A: The choice depends on your operation. Cabin control provides the operator with a protected, elevated viewpoint, which is excellent for visibility and comfort in continuous, high-volume operations like container handling. A wireless remote offers more flexibility for the operator to move around the load, which can be advantageous in certain yard applications.
Q: Can the crane’s structure be a truss or box type?
A: Yes. We offer both. A box girder design is standard for its clean look and strength. A truss girder design is lighter and offers better wind resistance, making it a cost-effective choice for very wide spans in windy locations.
Q: How do I get a quotation for a 30-ton double girder gantry crane?
A: For a precise proposal, please contact us with the key parameters: 1) 30-ton capacity, 2) Required span (width between the legs), 3) Required lifting height, 4) Whether you need cantilevers and their length, and 5) The intended application (e.g., container handling, block lifting).
