Gantry crane
QC Type Heavy Duty 20 Ton Gantry Crane with Double Girder
Product Overview
The Weiyuan QC Type Heavy Duty 20 Ton Gantry Crane is an industrial-grade lifting solution designed for maximum performance in demanding environments. Engineered with a robust double-girder structure, this crane is ideal for handling heavy loads in open yards, stockyards, railway freight stations, and port terminals. Its powerful design ensures superior stability and a large lifting capacity, making it a cornerstone for high-volume, heavy-duty operations. Built for reliability and efficiency, the QC Type crane optimizes material handling processes, reduces operational downtime, and enhances worksite safety.
Product Advantages
Superior Strength and Stability
Constructed with a double-girder bridge, this crane offers exceptional structural integrity and torsional rigidity. The heavy-duty steel frame is engineered to handle a 20-ton capacity with ease, providing a secure and stable platform for lifting and moving substantial loads over large spans.
High-Efficiency Performance
Equipped with a powerful trolley and hoisting mechanism, the QC Type crane delivers fast and smooth lifting speeds. This enhances operational productivity, allowing for quicker turnaround times in loading, unloading, and material positioning tasks, which is critical in high-traffic industrial settings.
Advanced Safety Features
Safety is paramount in its design. The crane includes multiple safety systems such as overload limiters, emergency stop functions, and robust travel limit switches. The open-cab design provides the operator with an excellent field of vision, ensuring precise control and awareness of the surrounding environment.
Durable for Harsh Environments
The entire structure is treated with a multi-layer, industrial-grade anti-corrosion paint finish. This protects the crane from weather, moisture, and chemical exposure, ensuring long-term durability and reliability, especially in outdoor and coastal applications.
Customizable for Specific Needs
Weiyuan offers full customization for the QC Type Gantry Crane. We can adjust the span, lifting height, power supply, and control methods to meet your specific operational requirements, ensuring a perfect fit for your facility.

FAQ
Q: What is the main advantage of a double girder gantry crane over a single girder?
A: A double girder gantry crane, like the QC Type, offers higher lifting capacities, greater stability over wider spans, and faster lifting and travel speeds. It’s designed for more intensive, heavy-duty applications compared to a single girder crane.
Q: Is this crane suitable for use in windy or coastal areas?
A: Yes. The QC Type crane is engineered for stability in outdoor environments. It features a robust structure and can be equipped with an anemometer and rail clamps for added safety in high-wind conditions, making it suitable for ports and coastal terminals.
Q: What kind of control system does the QC Type crane use?
A: The standard configuration is a fully enclosed cabin control, which provides the operator with a wide, clear view and protection from the elements. We also offer a wireless remote control option for operations that require more operator mobility and a different vantage point.
Q: Can the lifting height and span be customized?
A: Absolutely. Weiyuan specializes in tailoring our cranes to your exact needs. We will work with your technical specifications to design the crane with the precise lifting height, span, and capacity required for your worksite.
Q: What is the typical lead time for a custom-built QC Type crane?
A: As a manufacturer with nearly 40 years of experience, Weiyuan has a streamlined production process. Lead time depends on the complexity of the customization, but we always work to meet your project timelines. All cranes undergo rigorous testing and come with a full quality assurance report before shipment.
