Introduction to Rubber Tyred Gantry Cranes

Definition and Terminology

Rubber Tyred Gantry Cranes (RTGs), also known as rubber tired gantry cranes or transtainers, are mobile gantry cranes that operate on rubber tires. This allows them to move freely on the ground without the need for rail tracks.

Primary Uses

RTGs are primarily used in ports, intermodal terminals, and container yards for handling, stacking, and transferring intermodal containers. They are also employed in various other industries such as construction and logistics.

Working Principle of RTG Cranes

Mechanical, Hydraulic, and Electrical Systems

The working principle of RTG cranes is based on the synergy of mechanical, hydraulic, and electrical control systems. Here are the key components involved:
– Gantry and Beam: The main structure of the crane.
– Hoisting Mechanism: Driven by an electric motor, it controls the wire rope to lift or lower goods.
– Traveling Mechanism: Powered by a hydraulic system, it enables the crane to move flexibly on the ground.
– Control System: Precisely controls the entire operation according to preset programs and parameters.

Features of RTG Cranes

Flexibility and Mobility

RTG cranes use a tyre-type traveling mechanism, which offers higher mobile flexibility compared to rail-type cranes. They can be quickly transferred between different sites and adapt to changing working environments.

Operating Efficiency

These cranes have faster traveling and lifting speeds, allowing for the rapid completion of loading, unloading, and stacking operations. This enhances the efficiency of logistics transfer.

Adaptability

RTG cranes are suitable for various types of cargo, including containers, bulk cargo, and large components. They can be adjusted through the lifting mechanism and beam height to achieve efficient loading and unloading.

Safety and Reliability

Equipped with safety protection devices such as anti-collision systems and overload protection, RTG cranes ensure safe and reliable operation.

Maintenance

The modular design of RTG cranes makes maintenance and repair work easier, reducing maintenance costs.

Functions of RTG Cranes

Cargo Loading and Unloading

RTG cranes accurately control the lifting height of goods and cooperate with the traveling mechanism to realize rapid loading and unloading operations.

Cargo Stacking

In cargo yards, RTG cranes can stack cargo to designated positions according to preset stacking plans. They can achieve multi-layer and multi-column stacking, improving yard space utilization.

Cargo Transfer

RTG cranes transfer goods from one ship to another or from ships to land transportation means, facilitating rapid transfer of goods.

Steering Modes of RTG Cranes

Straight Mode

In straight mode, all wheels are aligned in the same direction, allowing the crane to move in a straight line. This mode is ideal for covering longer distances quickly.

Crab Mode

Crab mode enables the RTG crane to move diagonally by turning all wheels in the same diagonal direction. This mode is useful for quick repositioning and navigating tight spaces.

Technical Specifications and Design

Gantry Span and Lifting Heights

RTG cranes come in various configurations with different gantry spans (e.g., 20.8 m to 37.7 m) and lifting heights (e.g., 12.3 m to 21 m)[3].

Travel and Hoisting Speeds

These cranes have specified travel and hoisting speeds. For example, they can achieve hoisting speeds of 56 m/min without load and 28 m/min with rated load, and gantry travel speeds of up to 130 m/min without load[3].

Power and Drive Systems

RTG cranes are often powered by diesel generator systems or electric drive systems. Electric RTGs are becoming more common to improve environmental sustainability[5].

Environmental and Operational Considerations

Fuel Consumption and Pollution

Diesel-powered RTGs can be significant polluters, consuming up to 10 US gallons of diesel fuel per hour. Electric RTGs are being adopted to reduce environmental impact[5].

Automation and Technology

Automation technology is increasingly used in RTG operations to reduce human involvement, optimize container movements, and improve safety. Automated gate systems and cargo handling equipment are examples of such technologies[5].

Applications Beyond Container Handling

Construction and Manufacturing

Apart from container handling, RTGs are used in constructing large unbalanced structures, assembling manufacturing components, positioning pipelines, and bridge construction. Their versatility and flexibility make them valuable in various industrial applications[5].
