Gantry crane

Product Overview

The Weiyuan Rubber Tyre Gantry (RTG) Crane is a highly versatile and powerful lifting solution designed for exceptional mobility and flexibility in demanding environments. Unlike rail-mounted cranes, the RTG is equipped with durable rubber tires, allowing it to move freely throughout container yards, precast concrete plants, and large industrial sites. Engineered for heavy-duty performance and reliability, this crane offers superior lifting capacity and maneuverability, making it an essential asset for operations that require efficient stacking, loading, and transport of heavy loads over large areas.

Product Advantages

Unmatched Mobility and Flexibility
The primary advantage of the RTG crane is its freedom of movement. Powered by a diesel engine or electric power source and equipped with robust rubber tires, it can travel anywhere within your worksite, not being limited to a fixed rail path. This provides ultimate flexibility in yard planning and operational workflow.

High Yard Utilization and Stacking Density
With its ability to span multiple container rows and stack them high, the RTG crane significantly increases yard storage capacity. Its maneuverability allows for denser stacking configurations, maximizing the use of your available space and boosting operational efficiency.

Robust and Powerful Performance
Constructed from high-strength steel and powered by reliable diesel-electric systems, this crane is built for continuous, heavy-duty operation. It delivers powerful lifting and smooth travel, ensuring high productivity and rapid turnover of containers or heavy materials.

Precise Steering and Control
The RTG crane features advanced steering modes, including straight travel, 90° transverse travel, and pivot steering. This allows for precise positioning and easy navigation through tight yard layouts. The ergonomic operator cabin provides excellent visibility and advanced controls for safe and efficient handling.

Low Maintenance and High Reliability
Designed for durability in harsh outdoor environments, the Weiyuan RTG crane uses high-quality components from world-class brands. The modular design simplifies maintenance and inspections, ensuring high uptime and a long service life with a lower total cost of ownership.

Application Scenarios

Container Terminals and Ports
The RTG crane is the industry standard for stacking and moving ISO containers in port and inland container depots. Its ability to travel between stacking blocks and service trucks makes it a cornerstone of modern terminal logistics.

Precast Concrete and Prefabrication Yards
Ideal for lifting, transporting, and stacking large and heavy precast concrete elements, such as bridge beams, wall panels, and pipes. Its mobility allows it to cover extensive outdoor production and storage areas.

Heavy Industrial Manufacturing
Provides a flexible lifting solution for large manufacturing facilities that need to move massive components, such as wind turbine sections, large steel fabrications, and heavy machinery, both indoors and outdoors.

Shipbuilding and Repair Yards
Used for transporting large hull sections, ship blocks, and other major components around the shipyard. Its high capacity and mobility are crucial for supporting complex shipbuilding and repair projects.

FAQ

Q: What is the main difference between a Rubber Tyre Gantry (RTG) crane and a Rail Mounted Gantry (RMG) crane?
A: The key difference is mobility. An RTG crane runs on rubber tires and is powered by a diesel engine or cable reel, allowing it to move freely around a yard. An RMG crane runs on fixed steel rails and is typically powered by electricity from a conductor bar, limiting it to a specific path.

Q: What power options are available for the RTG crane?
A: The standard power source is a diesel generator set, which provides complete autonomy. We also offer hybrid solutions and fully electric options that use a cable reel connected to the mains power supply, which reduces emissions and noise.

Q: How does the crane achieve 90-degree steering?
A: The RTG is equipped with steerable wheelsets that can be rotated 90 degrees. This allows the crane to switch from traveling down a container aisle (longitudinal travel) to moving across the yard to a different aisle (transverse travel), providing exceptional operational flexibility.

Q: Is the RTG crane suitable for use in high winds?
A: Yes, RTG cranes are designed to operate safely in typical port and yard environments. They are equipped with anemometers to monitor wind speed and have specific operational limits. For storm conditions, they are fitted with tie-downs or storm anchors to secure the crane safely.

Q: How does Weiyuan ensure the quality and safety of its RTG cranes?
A: With nearly 40 years of experience in heavy equipment manufacturing, Weiyuan adheres to strict international quality standards (ISO). Every RTG is designed by our expert engineers, built with certified high-strength steel, and undergoes comprehensive testing of all systems. We ensure every crane meets rigorous safety and performance benchmarks before it is delivered and commissioned.
