RTG Crane Spreader

Introdução do Produto

The RTG Crane Spreader is the lifting device installed beneath a Rubber-Tyred Gantry (RTG) crane trolley. It is used for container lifting, transfer, stacking, loading, and unloading operations. By connecting to the container corner castings through a twistlock system, the spreader provides a secure connection during handling in ports, container terminals, and inland container yards.

A fixed RTG spreader has a fixed frame length and is designed for single-size container handling. The structure is simple and mainly used in dedicated or stable operating conditions.

• Container size: 20ft / 40ft (fixed configuration)
• Structure type: Non-adjustable frame
• Lifting mode: Single lift operation
• Maintenance level: Low

Applications: used in facilities handling a single container size or specialized lifting operations.

Telescopic RTG Spreader

A telescopic RTG spreader uses a hydraulic or electric extension system to adjust its frame length for different ISO container sizes. It is the most common type in container terminals.

• Container size: 20ft / 40ft / 45ft
• Adjustment type: Hydraulic or electric telescopic
• Operation mode: Single lift
• Application range: Port / ICD / rail yard / logistics terminal

Applications: Suitable for ports, inland container depots, rail terminals, and logistics yards handling mixed container sizes.

Rotating RTG Spreader

A rotating RTG spreader is equipped with a controlled rotation function to assist container alignment during loading and unloading. It is used where container positioning is not consistent.

• Rotation angle: ±5° (typical configuration)
• Container size: 20ft / 40ft / 45ft
• Control mode: Hydraulic or electric drive
• Function: Position adjustment during engagement

Applications: Used in container yards where precise container positioning is required or where containers may not be perfectly aligned.

Automatic RTG Spreader

An automatic RTG spreader integrates sensors and control systems for locking, positioning, and operation feedback. It is used in semi-automated and automated container terminals.

• Operation mode: Manual / Semi-automatic / Automatic
• Sensor system: Twistlock + position + load monitoring
• Control interface: RTG PLC integrated system
• Application: High-throughput / automated terminals

Applications:Suitable for high-throughput container terminals, semi-automated facilities, and automated port operations.

RTG crane spreader is built from several core mechanical and control components that work together during container lifting and stacking operations.

• Main Frame Structure: Steel structure that carries the spreader and container load. Welded high-strength steel, designed for lifting and travel loads.
• Telescopic Beam System: Adjusts length for 20ft and 40ft containers. Extension and retraction driven by hydraulic or electric system.
• Twistlock Assembly: Four corner locks that rotate 90° and lock into container corner castings for lifting.
• Hydraulic / Electric Drive System
• Drives telescoping and twistlock action. Hydraulic type for higher force, electric type for simpler maintenance.
• Sensors and Monitoring System: Checks lock position, travel limits, and load condition during operation.
• Anti-Collision Protection: Prevents contact between spreader, container, and nearby structures through buffers and sensors.

The structure and components of the spreader determine its stability, safety, and operating performance in container handling work.

Vantagens

RTG selection depends on operating requirements, yard conditions, and long-term cost considerations. The main factors below are used to evaluate whether a system fits the intended container handling operation.

A proper RTG configuration is determined by balancing lifting performance, yard layout, mobility, power system, automation level, and lifecycle cost based on actual terminal conditions.

Integration with RTG Crane Systems

RTG crane spreaders are connected to the crane’s lifting, power, and control systems. These systems work together during container lifting, transfer, and stacking operations.

Mechanical Integration

The spreader is connected to the RTG trolley and hoisting system. Lifting, lowering, and container positioning are completed through coordinated trolley and hoist movements.

Electrical Integration

Electrical connections provide power for telescopic beams, twistlocks, sensors, and auxiliary equipment installed on the spreader.

Control System Integration

Control signals are exchanged between the spreader and RTG control cabinet for locking, unlocking, telescoping, and status indication functions.

Compatibilidade com Automação

The spreader can be configured for manual, semi-automatic, or automatic RTG operations according to terminal requirements.

Remote Monitoring Options

Equipment status and operating information can be transmitted to remote control rooms and terminal management systems.

Mechanical, electrical, and control integration are important parts of RTG spreader operation, affecting container handling performance, equipment management, and terminal operations.

Recursos de segurança

RTG crane spreaders are equipped with multiple safety devices for container handling, equipment protection, and operational control.

• Twistlock Status Monitoring: Monitors the lock and unlock status of each twistlock during container handling operations.
• Overload Protection: Stops lifting operations when the load exceeds the rated capacity of the spreader.
• Emergency Release Function: Allows manual or emergency release of twistlocks when required during maintenance or special operating conditions.
• Anti-Collision System: Detects obstacles around the spreader and reduces the risk of contact with containers, vehicles, or structures.
• Position Detection Sensors: Monitor spreader position, telescopic beam movement, and container alignment during operation.

These safety features provide continuous monitoring of lifting, locking, positioning, and equipment status during daily operations.
