General purpose overhead crane
Double Girder Electric Overhead Travelling Crane
Product Overview
The Weiyuan Double Girder Electric Overhead Travelling (EOT) Crane is the ultimate solution for heavy-duty lifting and material handling in demanding industrial environments. Engineered for superior strength, stability, and performance, this crane features a robust double-beam design that allows for higher load capacities and wider spans than its single-girder counterpart. It is the workhorse of choice for steel mills, large manufacturing plants, power stations, and shipyards. Equipped with a high-performance electric hoist or trolley, this crane ensures safe, efficient, and precise movement of heavy loads, maximizing productivity and operational safety in your facility.
Product Advantages
Exceptional Lifting Capacity and Stability
The dual-girder structure provides outstanding torsional rigidity and stability, making it the ideal choice for lifting and transporting extremely heavy or bulky loads. This design minimizes deflection and ensures smooth, reliable operation even when handling loads at the upper end of its capacity.
Higher Lifting Height
By positioning the hoist or trolley to run on top of the two girders, this crane achieves a significantly higher lifting height compared to an under-slung single-girder crane. This is a critical advantage in facilities with limited headroom or where maximum vertical lift is required.
Wide Span and Versatile Configuration
The double-girder design is capable of spanning greater distances, providing extensive coverage across wide work bays. It also offers the flexibility to add service platforms, maintenance walkways, and auxiliary hoists, making it a highly adaptable system for complex operational needs.
Robust and Durable Construction
Built from high-grade Q235B or Q345B steel, the crane is manufactured to withstand the rigors of continuous, heavy-duty use. The robust construction and use of premium components from trusted brands ensure a long service life with minimal maintenance, delivering an excellent return on investment.
Advanced Safety and Control
Safety is paramount in our design. The crane is equipped with multiple safety features, including overload limiters, emergency stop systems, and travel limit switches. Advanced control options, such as variable frequency drives (VFDs) and wireless remotes, provide smooth, precise control over all movements for enhanced safety and accuracy.
Application Scenarios
Steel Mills and Metal Processing
Perfectly suited for handling steel coils, slabs, billets, and scrap metal. The high capacity and robust design can withstand the harsh conditions of the steel industry, from foundries to finishing mills.
Heavy Manufacturing and Assembly Plants
Ideal for lifting and moving large machinery, heavy engines, turbines, and massive fabricated components. Its precise control is essential for complex assembly and production processes in sectors like automotive, aerospace, and heavy equipment manufacturing.
Power Generation and Energy Sector
An indispensable tool for maintenance and operations in power plants. It is used for lifting and positioning heavy components like generators, turbines, and transformers, ensuring operational efficiency and safety.
Shipbuilding and Port Operations
Provides powerful lifting for moving large hull sections, ship engines, and other major components in shipyards. It is also used in ports for handling heavy cargo and containers, streamlining logistics and loading operations.

FAQ
Q: When should I choose a double girder crane over a single girder crane?
A: A double girder crane is the superior choice when you need to lift very heavy loads (typically over 20 tons), require a very wide span, need a high lifting height, or operate in a high-frequency, heavy-duty work environment (A5 work duty or higher).
Q: What is the difference between a hoist trolley and an open winch trolley?
A: A hoist trolley is a standard, compact unit suitable for most applications up to a certain capacity. An open winch trolley is a more robust, custom-built system designed for extremely heavy loads, higher lifting speeds, and severe-duty applications. It offers easier access for maintenance.
Q: Is a cabin control necessary for this crane?
A: A cabin control is highly recommended for cranes with long travel distances, high speeds, or those operating in harsh environments like steel mills. It provides the operator with a safe, climate-controlled vantage point for optimal visibility and control over all crane movements.
Q: Can this crane be installed in an existing building?
A: Yes, provided the building’s support structure (columns and runway beams) is professionally verified to safely handle the loads imposed by the crane. Weiyuan provides all the necessary wheel load and structural data to your building engineer for this assessment.
Q: How does Weiyuan ensure the quality and safety of its double girder cranes?
A: As a manufacturer with nearly 40 years of experience, Weiyuan adheres to a strict ISO-certified quality management system. Every crane is engineered by experts, fabricated from certified steel, and equipped with components from world-class brands. Before shipment, each crane undergoes rigorous inspection and full-load testing to guarantee it meets all international safety and performance standards.
