General purpose overhead crane
Weiyuan Double Girder Electric Overhead Travelling Crane
Product Overview
The Weiyuan Double Girder Electric Overhead Travelling (EOT) Crane is the ultimate heavy-duty lifting solution, engineered for maximum performance, safety, and reliability in demanding industrial environments. This crane is designed to handle high-capacity loads and cover wide spans with exceptional stability and precision. Featuring a robust double-girder structure and a high-performance electric hoist trolley, it is the ideal choice for steel mills, heavy manufacturing plants, power stations, and large-scale warehouses. By providing superior lifting height and operational stability, the Weiyuan double girder crane significantly enhances productivity, streamlines complex lifting tasks, and ensures a safer, more efficient workflow for your most critical operations.
Product Advantages
Superior Strength and Stability
The double-girder box-frame design provides exceptional torsional rigidity and structural integrity. This robust construction minimizes deflection and ensures maximum stability when lifting and transporting heavy or off-center loads, making it far superior to single-girder designs for high-capacity applications.
Higher Lifting Height
The hoist trolley runs on top of the two girders, allowing the hook to be raised significantly higher than on a single-girder crane. This design maximizes the effective lifting height within your facility, providing greater vertical clearance for handling oversized loads and optimizing your workspace.
High-Performance Hoisting and Travel
Equipped with a powerful electric wire rope hoist and advanced drive systems, this crane delivers fast and smooth lifting and travel speeds. Optional variable frequency drives (VFD) provide precise, stepless control, reducing load swing and allowing for accurate positioning of heavy components.
Durability for Heavy-Duty Use
Built with high-quality steel and premium components from brands like Schneider and Siemens, this crane is designed for high work duties (A5-A8) and long-term reliability in harsh industrial settings. The durable construction ensures a long service life with minimal maintenance requirements.
Enhanced Safety Features
Safety is paramount. The crane is equipped with a full suite of safety features, including overload protection limiters, emergency stop systems, travel limit switches, and a high-performance braking system, to ensure secure and reliable operation at all times.
Application Scenarios
Steel Mills and Metal Processing
Perfectly suited for handling steel coils, slabs, and finished products in the demanding environment of a steel mill. Its high capacity and robust design make it ideal for furnace charging, casting, and storage yard operations.
Heavy Manufacturing and Assembly
An indispensable tool for lifting and moving large machinery, heavy fabrications, and major components in industries like shipbuilding, aerospace, and heavy equipment manufacturing. Its precision control facilitates complex assembly tasks.

FAQ
Q: When should I choose a double girder crane over a single girder crane?
A: A double girder crane is the best choice for applications requiring a lifting capacity typically over 20 tons, a span longer than 20 meters, or a very high lifting height. Its design offers greater stability and durability for heavy-duty, high-frequency lifting tasks.
Q: What is the difference between an LH model and a QD model hoist trolley?
A: The LH model uses a standard electric wire rope hoist mounted on a trolley, which is ideal for general-purpose lifting up to around 50 tons. The QD model features a heavy-duty winch trolley, which is designed for higher capacities, faster speeds, and more severe working conditions (A6-A8 duty).
Q: What kind of runway and support structure is required?
A: An overhead crane runs on elevated runway beams supported by your building’s columns or an independent steel structure. A professional structural assessment is required to ensure the building can support the crane and its maximum load. We provide all necessary wheel load data for this evaluation.
Q: Can this crane be used for handling molten metal?
A: Yes, we offer specialized casting cranes (foundry cranes) designed for high-temperature environments. These cranes feature heat-resistant components, redundant braking systems, and other safety features specifically for handling molten metal safely.
Q: How does Weiyuan ensure the quality and safety of its overhead cranes?
A: With nearly 40 years of experience, Weiyuan manufactures all cranes under a strict ISO-certified quality control system. Each double girder crane is designed by our expert engineers, fabricated from certified high-strength steel, and undergoes rigorous non-destructive testing and a full load test before shipment to guarantee it meets all international safety and performance standards.
