Intermodal RTG Crane, also known as Intermodal Rubber-Tired Gantry Crane, is the core equipment for container transfer between different transport modes in intermodal hubs. Its main components and functions are as follows:

Metal Structure Body: Main load-bearing frame, including main beam, gantry legs, bottom beam, and trolley frame, providing structural support and overall stability for the whole machine.

Hoisting Mechanism: Responsible for vertical lifting of containers, using dual-drive units, drum system, and steel wire ropes to ensure stable hoisting performance.

Trolley Traveling Mechanism: Mounted on the main beam rail, enabling horizontal movement of the spreader for precise container positioning and transfer.

Gantry Traveling and Steering System: Controls whole machine movement with multi-wheel drive and steering functions, supporting straight, lateral, and in-situ rotation operations.

Container Spreader System: Telescopic structure for handling standard containers (20ft, 40ft, 45ft), with twist-lock and rotation functions for fast loading and unloading. Type: RTG Crane Spreader,Straddle Carrier Spreader

Power and Electrical Control System: Provides power supply and control via diesel, grid, or hybrid systems, combined with PLC and frequency control for stable operation and monitoring.

Safety Protection System: Includes overload, limit, wind speed, emergency stop, and anti-collision protection to ensure safe operation under all working conditions.

Intermodal RTG Crane is widely used in Port Crane Solutions and Container Yard Equipment scenarios, combining the characteristics of Rubber-Tired Gantry Crane structures to improve Container Handling efficiency and mobility. It is an important part of Port Crane Solutions and Container Yard Equi

Customization Options

An intermodal container crane is a core piece of equipment that enables efficient transfer of standard containers between different transport modes (railway, truck, ship), known as the “handling hub” of logistics terminals. Taking Intermodal RTG (Rubber-Tired Gantry Crane) as an example, customization options are designed around core functional modules to adapt to complex port, yard, or rail station environments.

أوضاع القيادة

Full-wheel steering: each tire can steer independently, supporting 360° rotation and diagonal travel, suitable for limited space yards.
Figure-eight steering: front and rear wheels turn in opposite directions, reducing the turning radius for narrow passages.
Crab steering: all wheels move in the same direction for lateral movement and precise positioning.

نظام الطاقة

Diesel generator set: traditional power source without an external grid, suitable for off-grid or high mobility sites, but with higher noise and emissions.
Cable reel power supply: uses grid power via cable reel, low noise and zero emissions, but limited by cable length.
Lithium battery + supercapacitor system: energy storage solution with energy recovery, suitable for green port applications.

نظام الدفع

Diesel-hydraulic drive: stable output, suitable for heavy duty, higher maintenance cost.
Diesel-electric drive: higher efficiency and lower noise compared to hydraulic systems.
Full electric drive: zero emissions, low noise, lower maintenance, becoming a mainstream trend.

نظام التحكم

PLC system: basic logic control for hoisting, traveling, and steering.
Frequency conversion system: stepless speed control for precision and energy management.
Remote control system: operation from the control room via cameras and sensors.

Intelligent Functions

Automatic positioning system: based on GPS, laser, or vision sensors.
Anti-sway system: reduces load swing during lifting.
Condition monitoring system: monitors motors, bearings, and wire ropes.
Yard Management System (YMS) integration: connects with terminal systems for scheduling.

These configurations work together to affect efficiency, adaptability, and intelligence level. Full electric drive combined with a lithium battery system, automatic positioning, and anti-sway functions forms an advanced Intermodal Container Crane solution. Users can select combinations based on site conditions, operation needs, and budget.

Selection Guide

When selecting a rubber-tired gantry crane (RTG) for intermodal transport applications, a comprehensive evaluation must be conducted based on a variety of factors.

Industry Application Requirements

Different intermodal terminals have different operational requirements, which directly affect crane selection. Ports typically require high-capacity RTGs for continuous container handling, rail terminals prioritize flexibility and efficient rail-side operations, while inland logistics centers often focus on cost-effective solutions with moderate throughput requirements.

Intermodal Operation Frequency

The intensity of container handling operations determines the required crane configuration. High-volume terminals generally require robust, heavy-duty RTGs for continuous operation, while lower-frequency facilities can benefit from more economical solutions. For applications involving frequent yard transfers, lightweight and highly mobile crane configurations offer greater operational flexibility.

Site Conditions

Yard layout, available space, and ground bearing capacity are key factors in crane selection. Large container yards typically benefit from wide-span cranes that maximize storage density, while smaller or irregular sites may require compact designs. Ground strength should also be evaluated to ensure safe and reliable operation.

خيارات إمدادات الطاقة

The available power source affects both operating costs and equipment flexibility. Diesel-powered RTGs offer independent operation, cable reel systems provide continuous power with low operating costs, and battery-powered RTGs combine zero-emission performance with flexible mobility, making them increasingly popular for modern terminals.

Environmental and Climate Conditions

Local environmental conditions influence crane design and protection requirements. Coastal areas often require enhanced wind resistance and corrosion protection, while cold-climate regions may need low-temperature electrical and hydraulic systems. Proper environmental adaptation helps ensure equipment reliability and service life.

The final selection requires a comprehensive, weighted evaluation of all the above factors, balancing equipment performance, initial investment, operating costs, and service life.

Price Factors

RTG Crane price depends on:

• Lifting capacity: higher capacity increases structural and drive costs.
• Span: a larger span requires stronger main beam systems.
• Lifting height: higher stacking needs more complex hoisting systems.
• Customization: automation, remote control, and special spreaders increase cost.
• Operating environment: corrosion and extreme climate require a reinforced design.
• Transport & installation: large equipment logistics and commissioning cost.

Price is determined by specification and application conditions.
