Overview of Rubber Tyred Gantry Cranes

Rubber Tyred Gantry (RTG) cranes, also known as rubber tired gantry cranes or transtainers, are mobile gantry cranes equipped with rubber tires. These cranes are designed to handle and stack intermodal containers in various settings, including container terminals, intermodal yards, and construction sites.

Key Features and Applications

Mobility and Versatility

• Unlike rail-mounted gantry cranes, RTGs are not confined to fixed tracks. They can move freely around the yard, enhancing their ability to stack and retrieve containers efficiently[1][2][5].

Primary Uses

• RTGs are primarily used for stacking and moving containers in container terminals. However, they are also employed in other industries such as construction, logistics, and manufacturing where flexible material handling solutions are necessary[1][2][5].

Different Steering Modes of RTG Cranes

Straight Mode

• In straight mode, all wheels of the RTG crane are aligned in the same direction, allowing the crane to move in a straight line. This mode is ideal for covering longer distances across the yard and is the most basic and commonly used steering mode[1].

Crab Mode

• Although not explicitly detailed in the sources, crab mode generally allows the crane to move sideways while the body remains parallel to the direction of travel. This mode is particularly useful for navigating tight spaces and optimizing container handling operations[1][5].

Transverse Mode

• In transverse mode, the crane can move perpendicular to its longitudinal axis, which is beneficial for quick repositioning and efficient container stacking[1][5].

Pivot Steering and Other Modes

• Other steering modes include pivot steering and oblique movement, which enable the crane to make sharp turns and maneuver in complex operational environments. These modes enhance the crane’s ability to adapt to varying yard conditions and operational requirements[1][5].

Operational Advantages

Increased Flexibility in Yard Operations

• The multiple steering modes of RTG cranes allow terminal operators to optimize yard layouts and container stacking strategies, maximizing the use of available space and minimizing handling times[1].

Time-Saving in Container Handling

• Modes like crab and transverse mode are effective in saving time during container handling operations by reducing the need for multiple repositioning maneuvers, thus streamlining the loading and unloading processes[1].

Reduced Operational Costs

• Efficient maneuvering reduces fuel consumption and wear and tear on the crane’s tires and other components. This leads to lower maintenance costs and reduced downtime[1].

Technical Specifications and Design

Capacity and Working Levels

• RTG cranes typically have capacities ranging from 35 to 50 tons and can operate at various working levels (e.g., A6, A7, A8)[3].

Span and Lifting Heights

• The gantry span of RTG cranes can vary from 20.8 meters to 37.7 meters, depending on the number of container rows and truck lanes. Lifting heights can range from 12.3 meters to 21 meters[4].

Drive Systems and Power Options

• RTGs can be powered by diesel generator systems or be fully electric. Electric RTGs (ERTGs) offer significant reductions in energy costs and environmental impact. They can be powered via conductor bar systems or cable reeling drums[2][5].

Automation and Technology

• Some RTGs incorporate automation technology to optimize container movements, track operations, and communicate with other systems. This includes automated gate systems and automated cargo handling equipment[2].

Environmental and Maintenance Considerations

Fuel Consumption and Pollution

• Diesel-powered RTGs can be significant polluters, consuming up to 10 US gallons of diesel fuel per hour. However, electric RTGs offer a more environmentally friendly alternative, reducing fuel consumption and emissions[2][5].

Maintenance and Energy Efficiency

• Modern RTG designs include features such as differential axles, anti-sway systems, and direct-driven electric motors, which reduce tyre wear, energy consumption, and maintenance needs[4][5].

Conclusion

Rubber Tyred Gantry cranes are essential components of modern container handling and material handling operations. Their versatility, enhanced by various steering modes, makes them highly adaptable to different operational environments.
