What Are the Parts of the RTG?

The parts of a Rubber Tired Gantry Crane (RTG) include the steel frame, main girder, operator cabin, hoist drums, trolley, and both horizontal and diagonal beams.

A tire gantry crane is usually a lifting device used in terminals or ports, and is often used to move containers. This article focuses on the components, operation and specifications of these cranes.

Introduction to RTG Cranes

RTG container cranes, widely used in ports and industrial facilities, are mobile gantry cranes designed for stacking and transporting containers. Equipped with rubber tires, these cranes can maneuver easily, reducing dependency on fixed tracks. Therefore, RTG cranes are often flexible enough to handle containers flexibly in ports.

Essential Parts of an RTG Crane

1. Steel Structure

The steel framework forms the backbone of an RTG crane. It consists of vertical legs connected by horizontal beams, which provide stability and strength. This construction allows the crane to support loads smoothly and is both strong and smooth, as well as durable.

2. Trolley and Hoist System

The trolley is mounted on the horizontal beam and houses the hoist mechanism. The hoist, often an electric motor-driven device, is responsible for lifting and lowering containers. Precision control systems enhance the accuracy of these operations, ensuring safe and efficient handling of cargo.

3. Rubber Tires and Steering Mechanism

Unlike rail-mounted gantry cranes, RTG cranes are fitted with rubber tires, providing flexibility in movement. The advanced steering mechanism allows the crane to switch between different modes, including straight-line, transverse, and carousel movements, to optimize maneuverability in tight spaces.

4. Power Supply System

RTG cranes typically operate on diesel generators, electric motors, or hybrid systems. These systems supply the necessary energy to power the hoist, trolley, and steering mechanisms. Hybrid systems are increasingly popular for their reduced environmental impact and operational cost savings.

5. Spreader Bar

The spreader bar is a crucial component used for gripping and lifting containers. Adjustable to fit containers of various sizes, the spreader bar ensures secure handling and prevents damage during transportation.

6. Operator Cabin

The operator cabin is ergonomically designed and equipped with advanced control systems, providing operators with a clear view of the operation area. The crane operator sits in the cab and can use a joystick or other control system to operate the crane.

7. Anti-Sway System

To maintain stability and prevent swaying during lifting operations, RTG cranes are equipped with an anti-sway system. This system reduces cargo swaying during crane lifting, helps in quick positioning and improves handling efficiency. It also improves the safety of the operation.

RTG Crane Specification and Dimensions

RTG crane specifications and dimensions vary depending on their application. Typical specifications include:

• Lifting Capacity: Ranges from 30 to 60 tons, depending on the model.
• Span: Generally between 20 to 30 meters, accommodating six to eight containers across.
• Height: Designed to stack containers up to five or six levels high.
• Travel Speed: Can reach up to 120 meters per minute, ensuring efficient container handling.

These dimensions and specifications allow RTG cranes to excel in container stacking and logistics, making them a preferred choice for port terminals and industrial warehouses.

Why Choose RTG Cranes?

1. Flexibility

RTG cranes are not confined to fixed tracks, making them ideal for dynamic operational environments.

2. Cost-Effectiveness

Their ability to maneuver without rails reduces infrastructure costs.
