General purpose overhead crane
Weiyuan Heavy-Duty Double Girder Overhead Crane

Product Overview
The Weiyuan Heavy-Duty Double Girder Overhead Crane is the ultimate lifting solution for demanding industrial applications, offering robust performance with customizable capacities from 30 to 50 tons and beyond. Engineered for superior strength, stability, and efficiency, this crane is the workhorse for heavy manufacturing, steel mills, large-scale construction, and power generation sectors. Its dual-beam design allows for higher capacities, wider spans, and greater lifting heights compared to single girder models. Equipped with a high-performance electric hoist or open winch trolley, the Weiyuan double girder crane ensures the safe, precise, and reliable movement of your heaviest loads, maximizing productivity in any heavy-duty environment.
Product Advantages
Exceptional Strength and Stability
The core advantage of this crane is its double-girder box frame, which provides outstanding torsional rigidity and structural integrity. This design minimizes deflection under heavy loads, ensuring maximum stability and safety. It’s the ideal configuration for handling massive loads and for applications requiring a high degree of operational precision and safety.
Optimized Lifting Height and High Capacity
By positioning the hoist to run on top of the two girders, this crane naturally achieves a superior lifting height. This is a critical feature for facilities needing to handle oversized components or maximize vertical clearance. With standard capacities of 30 and 50 tons, it is built to handle the most challenging lifts in modern industry.
High-Performance and Durable Construction
Engineered for a long service life, the Weiyuan double girder crane is constructed from high-grade steel and equipped with world-class core components, including robust motors, gearboxes, and bearings. The entire system is built to withstand heavy-duty work cycles (A5-A7), guaranteeing reliability and minimizing maintenance downtime.
Fully Customizable for Your Needs
We understand that no two workshops are the same. This crane is fully customizable to your specific requirements. We can tailor the lifting capacity, span, lifting height, and control methods to perfectly integrate into your facility and workflow.
Comprehensive Safety Systems
Safety is fundamental. Our double girder cranes come equipped with a full suite of advanced safety features, including overload protection limiters, redundant travel and lifting limit switches, emergency stop systems, and high-performance braking. These features work together to ensure fail-safe operation and protect your personnel and assets.

FAQ
Q: When is a double girder crane the right choice over a single girder crane?
A: A double girder crane is the superior choice for lifting heavy loads (typically over 20 tons), requiring wide spans, needing high lifting heights, or operating in high-frequency, heavy-duty work environments (A5 work duty or higher). It offers greater stability and durability for the most demanding tasks.
Q: What is the difference between a standard hoist trolley and an open winch trolley?
A: A hoist trolley is a standard, integrated unit suitable for most applications. An open winch trolley is a more robust, custom-built system designed for extremely heavy loads, higher lifting speeds, and severe-duty applications (A6-A8). It also offers easier access for maintenance.
Q: What information should I provide to get an accurate quotation?
A: For the best solution and price, please specify: 1) The required lifting capacity (e.g., 30 ton), 2) Crane span (the distance between your runway rails), 3) Required lifting height, 4) Your facility’s power supply, and 5) The intended application or materials to be lifted.
Q: Is a cabin control necessary for a heavy-duty crane?
A: For cranes with long travel distances, high speeds, or those operating in harsh environments like steel mills, a cabin control is highly recommended. It provides the operator with a safe, protected vantage point for optimal visibility and control over all movements.
Q: How does Weiyuan guarantee the quality and safety of its heavy-duty overhead cranes?
A: With nearly 40 years of manufacturing 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.
