General purpose overhead crane
Weiyuan Heavy Duty Double Girder Overhead Crane

Product Overview
The Weiyuan LH Model Heavy-Duty Overhead Crane is a robust and efficient lifting solution designed for demanding workshop environments. With flexible capacities of 10 and 20 tons, this double-girder crane provides the perfect balance of strength, simplicity, and performance. It consists of a strong box-shaped bridge, a reliable electric hoist trolley, and advanced controls. Engineered for convenience and durability, this crane is ideal for operational sites with medium to small lifting loads, such as factories, mines, and warehouses, where boosting efficiency and safety is paramount.
Product Advantages
Superior Strength and Lightweight Design
The core advantage of the LH model lies in its intelligent design. The double-girder bridge offers exceptional stability and strength, capable of handling loads up to 20 tons with ease. At the same time, it maintains a relatively light dead weight and a low overall height. This reduces the structural requirements of your building, saving on construction costs while ensuring powerful and reliable lifting performance.
Engineered for Reliability and Longevity
Built for a steady A3-A4 work duty, this crane is constructed for a long service life in typical industrial environments. Key components, including the motor and gearbox, are sourced from trusted brands, ensuring consistent performance. With optional frequency inverter control, you get smooth starts and stops, which reduces mechanical stress on the crane and minimizes load swing for safer, more precise handling.
Advanced Safety and Control
Safety is at the forefront of this crane’s design. It is equipped with a full suite of safety features, including weight overload protection, emergency stop systems, and travel limit switches for all directions of movement. Control is typically managed from a comfortable and secure operator cabin, providing excellent visibility and protection from the working environment, ensuring every lift is performed with confidence.
Fully Customizable for Your Workshop
We understand that every workshop is different. That’s why we offer extensive customization options for the LH crane. You can specify the exact lifting capacity (10T, 20T, or up to 32T), span (from 10.5m to 31.5m), lifting height, and power supply. We can also tailor the control method and even the color to ensure your crane is a perfect fit for your facility and operational needs.
Application Scenarios
- Manufacturing Plants: An excellent choice for assembling heavy equipment, moving raw materials, and transporting finished goods across the production floor.
- Machine Shops: Ideal for lifting and positioning heavy machine tools, large parts, and die sets with precision and control.
- Warehousing and Logistics: Perfect for efficient loading and unloading of trucks, organizing heavy stock, and general material handling.
- Maintenance Facilities: Provides the reliable power needed to lift and service heavy vehicles, industrial machinery, and other large components.

Frequently Asked Questions
Q: What is the main difference between an LH model and a QD model crane?
A: The LH model, as described here, is designed for light to medium-duty work (A3-A4) and typically uses a standard electric hoist trolley. It’s perfect for general workshops. The QD model is engineered for heavier, more frequent use (A5-A8) and uses a more robust winch trolley, making it suitable for more demanding environments like steel mills.
Q: What is the advantage of a frequency inverter (VFD) for speed control?
A: A VFD allows for smooth, variable speed control for the crane’s movements. This eliminates the jerking motion of single-speed cranes, which reduces load swing, improves operator control, increases safety, and minimizes wear and tear on the crane’s gears and brakes.
Q: Can this crane be installed outdoors?
A: The standard LH model is designed for indoor use. However, we can customize it for outdoor applications by adding protective rain covers for the hoist and electrical systems and applying a special corrosion-resistant paint finish to protect it from the elements.
Q: How do I get a quote for a 20-ton overhead crane?
A: To get a detailed quote, please provide our team with your key requirements: lifting capacity (20 tons), the span of your workshop bay, the required lifting height, your facility’s power supply details, and your preferred control method (cabin or remote). We will promptly prepare a comprehensive technical proposal for you.
