● Control Cabin: The control cabin is where the crane operator is stationed. It is equipped with a control panel, instruments, and displays for monitoring and operating the crane.

● Electrical and Control Systems: These systems include sensors, controllers, and software that manage the crane's operations. They are responsible for precise positioning, load control, and safety features.

● Safety Features:

■ Anti-Collision Systems: These systems help prevent collisions between RTG cranes and other equipment in the yard.

■ Load Monitoring and Control: Sensors are used to monitor the load being lifted and ensure it stays within safe limits.

■ Emergency Stop Systems: These are crucial for immediate shutdown in case of any safety concerns.

● Braking System: RTG cranes are equipped with braking systems to ensure precise and safe stopping of the crane's movement.

● Lighting and Signaling Equipment: RTG cranes often have lighting and signaling equipment for safety and operational purposes. This can include signal lights, warning horns, and more.

● Wheels and Axles: The wheels and axles are crucial for the crane's mobility. They enable smooth movement along the container stacks and rows.

● Cable Reel System: This system manages the electrical and control cables, allowing them to be extended and retracted as the crane moves.

 

These are the essential parts and components that make up a Rubber Tired Gantry Crane. Depending on the manufacturer and specific model, there may be variations and additional features to enhance performance, safety, and efficiency
