General purpose overhead crane
Weiyuan Heavy-Duty Gantry Crane
Product Overview
The Weiyuan Heavy-Duty Gantry Crane is a powerful and versatile lifting solution engineered for superior performance in outdoor and indoor environments where overhead runways are not practical. Available in capacities ranging from 10 to 20 tons, this crane is designed for strength, stability, and durability. It is the ideal choice for stockyards, rail freight terminals, ports, and heavy fabrication shops. Featuring a robust double-girder or single-girder A-frame design and a high-performance electric hoist, the Weiyuan Gantry Crane provides an efficient and reliable method for handling heavy loads, maximizing productivity and ensuring operational safety.
Product Advantages
Robust and Weather-Resistant Construction
Built from high-strength Q235B or Q345B steel, our gantry cranes are engineered to withstand demanding industrial use and harsh outdoor conditions. The structure is finished with a multi-layer painting process, including an anti-corrosive primer and a durable topcoat, ensuring a long service life with excellent resistance to the elements.
Versatile and Freestanding Design
As a freestanding structure that runs on rails laid on the ground, this gantry crane requires no support from the building’s structure. This makes it an incredibly versatile solution for open yards, areas beneath large overhead cranes, or inside facilities where ceiling support is not an option.
High Capacity and Wide Span Coverage
Engineered for heavy loads, our 10-20 ton models provide the strength needed for serious industrial lifting. The design allows for wide spans, enabling it to cover large work areas and handle bulky materials like containers, concrete beams, and large steel fabrications with ease.
Enhanced Safety and Reliability
Safety is our top priority. The gantry crane is equipped with a comprehensive suite of safety features, including overload protection, emergency stop systems, travel limit switches, and robust rail clamps or storm brakes for outdoor use. A reliable braking system ensures loads are held securely at all times.
Customizable for Your Application
We understand that every job is different. Weiyuan offers extensive customization options, including single or double girder designs, cantilever extensions on one or both sides to expand the work area, and various hoist and control options to create a crane that perfectly matches your operational needs.
Application Scenarios
Outdoor Stockyards and Storage Areas
Ideal for steel yards, precast concrete facilities, and raw material storage areas. The gantry crane can easily span multiple railway lines or truck lanes, making it perfect for loading, unloading, and organizing heavy and oversized materials.
Manufacturing and Heavy Fabrication
Provides powerful lifting for fabricating large components in sectors like shipbuilding, bridge construction, and heavy machinery manufacturing. Cantilever extensions allow for handling materials outside the main rail span, increasing flexibility.
Ports and Container Terminals
Well-suited for handling ISO containers and general cargo in smaller ports and inland terminals. Its robust design and high capacity ensure efficient and reliable container handling operations.
Railway Freight Yards
Provides a crucial lifting solution for transferring goods and materials between railway cars and trucks. Its ability to span multiple tracks streamlines logistics and reduces turnaround times.

FAQ
Q: What is the difference between a single girder and a double girder gantry crane?
A: A single girder gantry crane is generally more economical and suitable for capacities up to 20 tons and moderate spans. A double girder gantry crane is preferred for higher capacities, wider spans, higher duty cycles (A6 and above), and offers better hook height. It also provides a maintenance walkway for easier servicing.
Q: Can this gantry crane be used indoors?
A: Yes, gantry cranes are an excellent indoor solution when a building cannot support a runway for an overhead crane or when you need to supplement an existing overhead crane system for a specific area.
Q: What information do I need to provide for a quotation?
A: To give you an accurate price, please provide the following: 1) Required Lifting Capacity (e.g., 16 ton), 2) Crane Span, 3) Lifting Height, 4) Whether you need cantilevers and their lengths, 5) Your Power Supply, and 6) A description of the materials being lifted and the working environment.
Q: What is a cantilever?
A: A cantilever is an extension of the main girder that projects beyond the crane’s legs. It allows the hoist to travel outside the main span, increasing the work area and providing greater flexibility for loading and unloading at the edge of the crane’s path.
Q: How does Weiyuan ensure the quality of its gantry cranes?
A: With nearly 40 years of manufacturing experience, Weiyuan produces all cranes under a strict ISO-certified quality management system. Every gantry crane is designed by our expert engineers, fabricated from certified steel, and equipped with reliable components. Full load testing is performed before shipment to guarantee it meets our high standards for safety, durability, and performance.
