Guide to Rubber Tyre Gantry Cranes for Buyers and Users

Rubber tyre gantry cranes, often called RTG cranes or rubber tyred gantry cranes, deliver flexible and trackless heavy lifting options for busy work sites. These mobile cranes perform well in container handling and various industrial tasks. They provide better mobility than rail-based systems.

1. What Are Rubber Tyre Gantry Cranes?

Rubber tyre gantry cranes (RTG cranes) act as mobile gantry systems. They travel freely on rubber tyres and do not need fixed rails at all. They lift, move, and stack heavy loads in an efficient way inside open yards.

Key parts include the main girder (which can be single or double), the hoist or winch system, rubber tyre end carriages that allow steering, the power supply setup, and controls for the operator (such as pendant, remote, or cabin). These cranes rely on large solid or pneumatic tyres. The tyres help them move smoothly across prepared surfaces.

RTG cranes stand apart from traditional fixed cranes. They focus more on flexibility instead of permanent setup. This quality makes them perfect for places where layouts change often.

1.1. Rubber Tyre Gantry Crane Definition

A rubber tyre gantry crane serves as a wheeled mobile gantry crane. People sometimes refer to it as a transtainer. It handles stacking intermodal containers or moving industrial materials. The rubber tyres allow movement in many directions. They support 90-degree steering for accurate placement. This trackless setup cuts down on infrastructure costs. At the same time, it keeps strong lifting ability.

1.2. Rubber Tyred Gantry Crane vs Rail Mounted Gantry Crane

RTG cranes and rail mounted gantry (RMG) cranes handle similar jobs. However, they differ in important ways.

Mobility: RTG cranes move freely around yards. RMG cranes stay limited to fixed rails.

Infrastructure: RTG cranes need no rails, so initial costs stay lower. RMG cranes demand expensive rail setups.

Flexibility: RTG cranes adjust easily to layout shifts. RMG cranes give greater precision and better automation options.

Power and Costs: RTG cranes usually run on diesel for independent work, but fuel expenses rise. RMG cranes often use electric power for better efficiency.

Typical Use: RTG cranes fit dynamic or medium-volume yards well. RMG cranes shine in high-throughput fixed terminals.

RTG cranes bring more versatility. RMG cranes supply added stability in organized settings.

2. Types of Rubber Tyre Gantry Cranes

Rubber tyre gantry cranes appear in several setups. These match different load needs and site conditions.

Common varieties feature single girder models for lighter work and double girder models for heavier tasks.

2.1. Single-Girder Rubber Tyre Gantry Crane

Single-girder versions have just one main beam. This design keeps them compact and more affordable.

Load capacity: Usually 2-20t, and sometimes up to 63t in certain builds.

Ideal for light to medium loads in smaller yards or industrial areas.

Benefits: They offer easier handling, reduced cost, and simpler upkeep.

These work best in operations that do not demand very high stability or capacity.

2.2. Double-Girder Rubber Tyre Gantry Crane

Double-girder models include two parallel beams. This adds extra strength.

Load capacity: 5-100t or more, especially with winch setups for tough duties.

Advantages: Better stability, wider spans, and more dependable lifting.

Suited for heavy-duty settings that require solid performance.

Many come with hoist or winch choices to meet various lifting demands.

2.3. Other Configurations (Special Frame Designs)

Special frames, like A-frame or U-type, bring improved stability or easier access.

A-frame: Provides even load spread on uneven ground.

U-type: Allows better access underneath the crane for some stacking jobs.

Custom options fit special site limits.

These designs increase adaptability beyond basic girder styles.

3. Specifications & Technical Details

Rubber tyre gantry crane specifications change depending on the model and custom features.

Important parameters help guide the right choice for performance and safety.

3.1. Load Capacity & Span Range

Load capacity goes from 2t in lighter models to over 100t in strong heavy-duty ones.

Common: 20-65t for container work.

Span: 5-40m, which covers several rows along with access paths (for example, 20-35m is typical).

Span decides how much area the crane covers. Wider spans work well for bigger stacking zones.

3.2. Lifting Height, Speeds, and Other Parameters

Lifting height reaches 3-60m. It often sits at 12-21m for stacking 1-over-3 to 1-over-6 containers.

Hoisting speed: 12-50 m/min.

Travel speed: 30-130 m/min for the gantry, 70 m/min for the trolley.

Steering: 90° rotation gives great flexibility.

Deflection: 1/700 to 1/1000 according to standards.

These features support smooth and secure work.

3.3. Power Source Options (Diesel, Electric, Hybrid)

Power choices affect efficiency and the environment.

Diesel: Allows free movement and suits remote locations.

Electric: Cuts running costs and helps the environment (like eRTG versions).

Hybrid: Combines power with greener benefits.

Diesel fits flexible yards. Electric lowers emissions.

4. Key Features and Advantages

Rubber tyre gantry cranes bring clear benefits compared to other options.
