What is a Rubber Tyre Gantry Crane?

A Rubber Tyre Gantry Crane (RTG) is a type of mobile crane that operates on rubber tires instead of being fixed to rails. This design allows the crane to move freely within a designated area, providing flexibility and efficiency in material handling operations. RTGs are predominantly used in container terminals and intermodal yards but are also suitable for industrial sites and construction projects.

Basic Components of a Rubber Tyre Gantry Crane:

• Main Girder: The primary horizontal beam that supports the load. It spans the width of the crane and provides structural integrity.
• Support Legs: Vertical structures that connect the main girder to the base and house the wheel assemblies. These legs provide stability and balance.
• Hoist Mechanism: The system responsible for lifting and lowering the load. It typically includes a motor, drum, and wire rope or chain.
• Trolley: A movable carriage that runs along the main girder, allowing the hoist mechanism to traverse horizontally.
• Rubber Tires: Large, durable wheels that enable the crane to move across various surfaces. These tires provide the mobility that distinguishes RTGs from rail-mounted gantry cranes.
• Control Cabin: The operator’s station equipped with controls for maneuvering the crane and managing load operations. In some advanced models, the control system may be remote or automated.
• Power Source: Depending on the design, RTGs may be powered by diesel engines, electric motors, or a combination of both in hybrid models.

Comparison with Other Types of Gantry Cranes

Rubber Tyre Gantry Cranes differ from other gantry cranes primarily in their mobility and flexibility. Here’s a comparison with some common types of gantry cranes:

Rail-Mounted Gantry Cranes (RMGs):

• Mobility: Unlike RTGs, RMGs are fixed to rails and move along a predefined track. This limits their flexibility but provides precise linear movement.
• Applications: RMGs are typically used in environments where the layout is static, such as large container terminals or industrial yards with fixed infrastructure.
• Cost and Infrastructure: RMGs require substantial infrastructure investments in rails and power supply systems, which can be costly to install and maintain.

Overhead Bridge Cranes:

• Mobility: These cranes are mounted on a fixed overhead structure, providing vertical and horizontal movement within a confined area.
• Applications: Commonly used in factories, warehouses, and workshops where the workspace is well-defined and does not require frequent reconfiguration.
• Flexibility: Overhead bridge cranes offer less flexibility compared to RTGs as they are confined to the area beneath their supporting structure.

Portal or Full Gantry Cranes:

• Mobility: Similar to RMGs, portal cranes are typically rail-mounted but can be designed with rubber tires for limited mobility.
• Applications: Used in shipyards, large construction sites, and other heavy-duty applications where both height and span are critical.
• Structure: Portal cranes usually have a large, robust structure designed for heavy lifting, making them less suitable for applications requiring frequent movement.

Mobile Cranes:

• Mobility: Equipped with rubber tires, mobile cranes can travel on roads and rough terrain, offering maximum flexibility and portability.
• Applications: Ideal for construction sites, temporary projects, and situations where the crane needs to move frequently between locations.
• Load Capacity: Generally have a lower load capacity compared to RTGs and other fixed gantry cranes.

In summary, Rubber Tyre Gantry Cranes stand out for their mobility and versatility, making them ideal for dynamic environments like ports and intermodal yards where the ability to relocate and reconfigure operations quickly is crucial. Their design provides a balance between the heavy-duty capabilities of fixed gantry cranes and the flexibility of mobile cranes, offering a unique solution for efficient material handling.
