Rubber Tyred Gantry Crane

What Is a Rubber Tyred Gantry Crane?

Rubber Tyred gantry cranes, often referred to as RTG cranes, are essential machines in the world of cargo handling. These cranes are designed to efficiently lift, move, and stack shipping containers in various settings, such as ports, container yards, and logistics hubs. Let's dive into their concept, design, working principle, basic functions, and primary application areas. RTG cranes are engineered to provide mobility and flexibility in handling containers. Unlike traditional cranes that are fixed to tracks or rails, RTG cranes are equipped with rubber tires, allowing them to move freely on solid surfaces. This mobility enables them to reach containers stored in different locations within a terminal.

The working principle of an RTG crane is straightforward. It utilizes a spreader, a device equipped with twist locks or other mechanisms, to attach to containers. The crane's lifting mechanism raises or lowers the spreader to move containers vertically. Additionally, the rubber tires enable the crane to maneuver horizontally. The primary functions of an RTG crane include lifting containers from the ground, stacking containers in rows and tiers, and retrieving containers for loading onto trucks or ships. These cranes play a pivotal role in the efficient movement of goods in the global supply chain.

RTG cranes find their main applications in container handling operations. They are commonly used in ports and container yards to manage and organize containers, ensuring smooth cargo flow. Their versatility allows them to handle various container sizes and types, making them indispensable in the world of logistics.

Price Note: Pricing for RTG cranes can vary significantly based on factors such as lifting capacity, features, and manufacturer. It's essential to request quotes from crane suppliers for accurate pricing information.

Rubber Tyred Gantry Crane Parameters

Understanding the key parameters of an RTG crane is crucial for selecting the right crane for your needs. Let's explore parameters like lifting capacity, working radius, span range, lifting speed, and gain insights into using this equipment effectively.

1. Lifting Capacity: The lifting capacity of an RTG crane indicates the maximum weight it can safely lift. RTG cranes come in various capacities, typically ranging from 30 to 65 tons or more. Select a crane with a lifting capacity that matches the heaviest loads you'll handle.
2. Working Radius: The working radius is the distance from the crane's center to the point where it can effectively lift or lower a load. Understanding this parameter helps in positioning the crane accurately for container handling.
3. Span Range: The span range refers to the horizontal distance between the two parallel runways or rails on which the crane travels. Ensure that the crane's span covers the entire area where you need to move containers.
4. Lifting Speed: Lifting speed determines how quickly the crane can raise or lower a load. It's essential to balance lifting speed with load stability and safety. Slower speeds are often preferred for precise positioning.
5. Usage Tips and Technical Guidance: Always adhere to the crane's specified lifting capacity to prevent accidents and equipment damage. Ensure the crane's rubber tires are well-maintained to support smooth mobility. Regularly inspect and maintain the crane to extend its lifespan and ensure safe operation.

Components and Functions of RTG Crane

RTG crane components: An RTG crane houses the crane's critical components, including the operator cabin, control systems, and the spreader. The rubber tires are attached to the base of the gantry legs, providing mobility.  These components work together to perform container handling tasks efficiently. 

• Rubber Tires: These specialized tires enable the crane's mobility.
• Gantry Structure: The gantry structure includes vertical legs and a horizontal beam (gantry girder) that supports the lifting machinery.
• Spreader: The spreader is the attachment used to lift, lower, and handle containers.

RTG crane functions:

• The rubber tires allow the crane to move laterally and forward/backward on solid surfaces.
• The gantry structure supports the spreader and houses the operator cabin.
• The spreader securely grips containers for lifting, lowering, and positioning.

Advantages of RTG Crane

• Mobility: The rubber tires offer excellent maneuverability without the need for tracks or rails.
• Versatility: RTG cranes can handle various container sizes and types.
• Efficiency: They efficiently stack and retrieve containers, optimizing cargo operations.
• Flexibility: RTG cranes can reach containers stored in different areas within a terminal.
• Reduced Infrastructure: Their mobility reduces the need for extensive fixed infrastructure.
• Global Trade Support: RTG cranes contribute to the smooth flow of goods in international trade.

User Guide and Maintenance Service of RTG Crane

Usage Guide:

• Follow the manufacturer's instructions for crane operation and maintenance.
• Ensure that operators are trained and certified to operate RTG cranes safely.
• Regularly inspect the crane's tires, hoisting mechanisms, and structural components for signs of wear or damage.
• In the event of a malfunction or issue, immediately report it to maintenance personnel for prompt repairs.
• Maintain a log of routine inspections and maintenance to identify potential issues before they become major problems.

Maintenance Guidelines:

• Schedule routine inspections to check for wear and tear, loose bolts, and damaged components.
• Lubricate moving parts as recommended by the manufacturer to ensure smooth operation.

Why Custom a Crane Solution?

At Yuantai, we know that there is no "one size fits all" in the lifting field. Universal cranes are suitable for general factories, warehouses, etc. Besides, different applications have different needs for cranes. For example, steel industries often lift steel plates, so need electromagnetic cranes. Ports and docks often need to load ore, gravel, and other bulk goods, so need to grab bucket cranes. Chemical dangerous places often need to carry flammable and explosive materials, so need explosion proof cranes.

So, we provide customized cranes according to the special needs of our customers. Custom crane solutions offer many benefits in a variety of applications：
