Gantry crane
Weiyuan Gantry Crane for Marble and Concrete
Product Overview
The Weiyuan 20-30 Ton Gantry Crane is a specialized heavy-lifting machine engineered for the precise and careful handling of large, heavy, and often fragile materials like marble slabs and precast concrete beams. Combining a robust double girder or single girder structure with capacities of 20 and 30 tons, this crane is the definitive solution for stone processing yards, precast concrete plants, and large-scale construction sites. Its sturdy, rail-mounted design ensures stable and smooth movement, providing the strength and control required to lift and transport valuable, heavy materials safely and efficiently.
Product Advantages
- Specialized for Heavy, Brittle Materials: Designed specifically for industries handling marble, granite, and precast concrete, this crane provides the stability and smooth control necessary to prevent cracks and damage during lifting.
- Robust and Stable Performance: The strong girder structure (available in single or double configurations) offers exceptional rigidity, minimizing deflection and ensuring a secure lift for heavy, wide loads.
- High Productivity in Outdoor Yards: Built for heavy-duty work cycles, this gantry crane is perfect for continuous operation in outdoor stockyards, enhancing workflow from block cutting to finished product storage and loading.
- Durable and Weather-Resistant: Fabricated with high-strength steel and a protective coating, the crane is designed to withstand harsh weather conditions, ensuring long-term reliability and performance in outdoor environments.
- Customized to Your Needs: Weiyuan provides full customization, allowing you to specify the lifting capacity (20 or 30 tons), span, lifting height, and control system to create a crane that perfectly fits your yard’s layout and operational needs.
Application Scenarios
- Stone Processing and Marble Yards: Its primary application is for lifting and moving large marble and granite blocks and slabs safely around cutting, polishing, and storage areas.
- Precast Concrete Plants: Essential for handling and stacking long and heavy precast concrete beams, panels, and other structural elements.
- Bridge and Highway Construction: Ideal for lifting and placing heavy concrete girders and bridge segments during infrastructure projects.
- Large-Scale Building Construction: Facilitates the movement of heavy structural components and materials across large construction sites.
- Heavy Fabrication Yards: Suitable for moving large steel structures and other heavy fabricated items in an outdoor setting.

FAQ
1. Why is this crane specifically good for marble and precast concrete?
The crane’s design prioritizes stability and smooth control. Sudden jerks or excessive sway can cause fragile materials like marble to crack. Our crane’s rigid structure and optional VFD controls ensure a gentle, steady lift, protecting your valuable materials.
2. Should I choose a single girder or double girder design?
For wider spans and capacities at the higher end (like 30 tons), a double girder design is often recommended for its superior stability. For shorter spans and 20-ton loads, a single girder can be a more cost-effective solution. Our engineers can help you choose the best option.
3. What kind of lifting attachment is used for concrete beams or marble slabs?
The crane is typically used with specialized lifting beams, slings, or clamps designed for these specific materials. We can help you source or design the appropriate below-the-hook attachments for your needs.
4. Can this crane operate on uneven ground?
No, as a rail-mounted gantry crane, it requires a flat, stable foundation with properly installed steel rails to operate safely and effectively.
5. How is the crane delivered and assembled?
The crane is manufactured in sections for easy transportation. The main beams, legs, and other components are bolted together on-site. Weiyuan can provide detailed installation guidance or an on-site installation team upon request.
