Gantry crane

Product Overview

The Weiyuan Rubber Tyre Gantry (RTG) Crane is a premier, heavy-duty lifting solution engineered for maximum mobility and operational efficiency. Designed for the dynamic needs of modern container terminals, precast yards, and large industrial sites, this crane moves on robust rubber tires, offering unparalleled flexibility compared to rail-mounted alternatives. Weiyuan provides a comprehensive “Design and Supply” service, delivering a custom-engineered RTG crane that perfectly matches your site’s specific requirements. This powerful and reliable machine is built to enhance productivity, optimize yard space, and ensure safe handling of the heaviest loads.

Product Advantages

Complete Design and Supply Solution
Weiyuan offers an end-to-end service, from initial consultation and engineering design to manufacturing, delivery, and commissioning. We work closely with you to engineer an RTG crane that is perfectly tailored to your operational needs, yard layout, and performance targets.

Unmatched Mobility and Flexibility
Free from the constraints of rails, the RTG crane can travel anywhere in your facility. Powered by a reliable diesel-generator set or a direct electric connection, its ability to move between rows and across the yard provides ultimate flexibility in workflow and site management.

Maximized Yard Storage Capacity
With its ability to span wide stacking blocks and lift containers high, the RTG crane dramatically increases storage density. This efficient use of space allows you to store more in the same footprint, maximizing the capacity and profitability of your terminal or yard.

Advanced Steering for Precision Maneuvering
Equipped with sophisticated steering technology, the RTG crane can perform straight travel, 90-degree transverse movements, and pivot steering. This ensures precise positioning and easy navigation through congested areas, improving both safety and cycle times.

Durable Construction for Harsh Environments
Built from high-strength, certified steel and coated with a marine-grade anti-corrosion paint system, our RTG cranes are designed for a long service life in demanding outdoor environments. We use high-quality components from world-leading brands to ensure maximum reliability and uptime.

Application Scenarios

Container Terminals and Ports
The cornerstone of modern container handling, our RTG cranes are used for stacking ISO containers, loading and unloading trucks, and managing yard inventory. Their mobility and high efficiency are essential for high-throughput port operations.

Precast Concrete Yards
An ideal solution for handling and transporting large, heavy precast concrete products such as bridge girders, segments, and large pipes. The crane can cover vast storage areas and precisely position items for loading.

Heavy Industrial and Steel Fabrication
Provides flexible heavy lifting for manufacturing plants that need to move large assemblies, structural steel beams, and heavy machinery around a large site, both indoors and outdoors.

Shipbuilding and Repair
Crucial for transporting massive hull blocks, engine components, and other large sections around the shipyard. The RTG’s high capacity and mobility support efficient shipbuilding and repair schedules.

FAQ

Q: What does the “Design and Supply” process involve?
A: Our “Design and Supply” service is a turnkey solution. It starts with a detailed analysis of your operational needs. Our engineers then design a custom RTG crane with the optimal span, height, and features. We manage the entire manufacturing process, followed by delivery, on-site installation, and commissioning support.

Q: What is the difference between a diesel-powered and an electric-powered RTG?
A: A diesel-powered RTG has its own onboard generator, offering complete autonomy to move anywhere. An electric RTG (E-RTG) is powered through a cable reel connected to the grid, offering zero emissions, lower noise, and reduced energy costs, but its movement is tethered to the cable management system. We also offer hybrid options.

Q: How does the crane handle and stabilize containers?
A: The crane uses a specialized lifting spreader that locks onto the corners of ISO containers. Advanced anti-sway systems, both mechanical and electronic, are integrated to minimize container movement during travel, ensuring fast and safe positioning.

Q: Can this crane be used for materials other than containers?
A: Yes. While commonly used for containers, we can design the RTG with different lifting attachments, such as hooks, grabs, or custom lifting beams, to handle a wide variety of other heavy loads like precast concrete elements, steel coils, or large machinery.

Q: How does Weiyuan guarantee the quality and long-term performance of its RTG cranes?
A: As a leading manufacturer with nearly 40 years of experience, Weiyuan builds every RTG under a strict ISO-certified quality system. We use advanced design software (like FEM analysis) to ensure structural integrity. All materials are certified, all welds undergo non-destructive testing, and every system is rigorously tested to guarantee it meets international standards for safety, reliability, and performance.
