Weiyuan QD Model Heavy Duty Overhead Crane
Product Overview
The Weiyuan QD Model Heavy Duty Overhead Crane is the ultimate solution for lifting extreme loads in demanding industrial environments. Engineered for power and precision, this double girder crane is available in capacities ranging from 30 to over 450 tons. It is designed to be the workhorse of your facility, combining a robust structure, advanced control systems, and a high-performance winch trolley to handle the heaviest and most critical lifts with unmatched safety and reliability. This crane is essential for heavy manufacturing, assembly plants, and large-scale construction projects.
Product Advantages
Massive Lifting Capacity
The defining feature of the QD Model crane is its immense strength. With standard configurations for 30, 50, and 80 tons, and the ability to be customized for even greater loads, this crane is built to move your heaviest components, machinery, and materials. The double girder design provides exceptional stability and rigidity, preventing structural deflection under extreme weight and ensuring every lift is secure.
Built for Longevity and Performance
Engineered for a high work duty (A5-A8), this crane is designed for a long life of continuous, heavy use. We use high-grade Q235B/Q345B steel, precision-cut with CNC technology and protected by an epoxy zinc-rich paint finish for corrosion resistance. Core electrical components are sourced from trusted global brands like Schneider and Siemens, guaranteeing reliable performance and minimizing downtime.
Flexible and Precise Control
Managing heavy loads requires precision. The QD crane offers multiple control options to suit your workflow, including a ground-level pendant, an ergonomic operator cabin, and a wireless remote for maximum safety and visibility. With optional VFD (Variable Frequency Drive) control, you can achieve smooth, step-less speed adjustments for acceleration and deceleration, drastically reducing load swing and allowing for exact positioning of sensitive equipment.
Comprehensive Customization
Your facility is unique, and your crane should be too. We offer extensive customization options, allowing you to specify the exact lifting capacity, span (up to 31.5m), lifting height, and power supply. You can also add specialized lifting attachments like magnets or C-hooks, making the crane a versatile tool for a wide range of heavy lifting tasks.
Application Scenarios
- Heavy Manufacturing & Assembly: Perfect for lifting and positioning large machine tools, heavy molds, turbines, and massive fabricated components in production halls.
- Steel Mills and Foundries: An indispensable tool for transporting steel coils, slabs, and other heavy materials through the production process.
- Power Generation Plants: Ideal for maintenance and installation of heavy equipment like generators, turbines, and transformers.
- Large-Scale Warehousing: Provides the power needed to move and stack heavy inventory, oversized containers, and bulk goods in large storage facilities.

Frequently Asked Questions
Q: What does the “A5-A8 Work Duty” rating mean for this crane?
A: The work duty classification indicates the crane’s suitability for different levels of operational intensity. An A5-A8 rating signifies that this crane is engineered for medium to severe service, meaning it can handle frequent, heavy lifts in demanding, multi-shift environments like steel mills or high-volume manufacturing plants, ensuring a very long operational life.
Q: What is the benefit of VFD (Variable Frequency Drive) speed control?
A: VFD control allows for smooth and precise adjustment of the crane’s movement speeds. Instead of abrupt starts and stops, the crane accelerates and decelerates gently. This significantly reduces load swing, enhances operator control, improves safety, and minimizes wear and tear on the crane’s mechanical components.
Q: Can this crane be installed in our existing workshop?
A: Yes, our QD Model cranes are designed to be installed on existing runway systems, provided the building structure can support the crane and its rated load. Our engineering team will work with you to review your facility’s specifications to ensure a safe and proper fit.
Q: How do I get a quote for a 50-ton overhead crane?
A: To receive a detailed and accurate quote, please provide our team with your key requirements: lifting capacity (50 tons), the span of your workshop, the required lifting height, your facility’s power supply details, and your preferred control method. We will promptly prepare a technical proposal and quotation for you.
