What Is RTG Crane

In this article, RTG container gantry crane is introduced in detail, including its definition, structure and parts, components function, application, specs, price etc. This article will make you learn more info about RTG crane for your handling needs.

What Is RTG Crane？

A rubber tyre gantry (RTG) Crane is a mobile heavy-duty machine for container handling in ports, intermodal yards, and logistics hubs. It features a steel gantry structure mounted on rubber tires, enabling flexible movement across yards without fixed rails. With lifting capacities ranging from 30 to 65 tons under the spreader, RTGs can stack containers up to 1-over-6 high (7 tiers) and span up to 8 container rows plus a truck lane.

Equipped with 90° rotating tyres and cross-driving modes, RTGs move and work efficiently in tight spaces. Key components include a trolley with anti-sway technology, advanced PLC systems, and modular power options. It features remote monitoring, predictive maintenance, and automated container tracking to enhance productivity and safety.

Compared to rail-mounted gantry (RMG) cranes, RTGs provide unmatched mobility for dynamic yard layouts. Their robust design, eco-friendly variants, and adaptability make RTGs a cornerstone of modern container logistics.

RTG Crane Structure And Parts

The RTG gantry crane is a highly efficient container handling equipment widely used in ports and storage yards. Its main structure includes a main girder, outriggers, a tire-operated system, and a lifting trolley.

• Main Structure: Q235/Q345 carbon structural steel, large span and high lifting capacity.
• Traveling Machine: Top-quality rubber, good abrasion resistance, flexible turning.
• Trolley: Smooth running, no rail gnawing, low noise, safe and reliable.
• Container Spreader: Master link with four legs, wire rope sling sturdy safety, flexible control system.
• Drivers' room: all-round view, comfortable operating console.

3D Structure and Parts

• Rubber Tyres: Bear weight of cranes, adapt to unpaved ground in yards, enable flexible movement and require no fixed rails.
• Trolley Device: Moves horizontally along main girder, drives spreader to adjust precise position.
• Container Spreader: Locks with the corner fittings of containers to achieve reliable grabbing/releasing.
• Hoisting Mechanism: Drives spreader to achieve vertical lifting/lowering of containers.
• Anti-Sway System: Suppresses sway of spreader and prevents container collision.
• PLC Control System: Realize coordinated movements, control operating parameters, and simplify operation.
• Steering Control System: Controls the steering angle, supporting 90° right-angle steering and diagonal movement.
• Safety Monitoring System: Displays the load and position in real time, alarms when overloading or over-limiting occurs.

What Is RTG Crane Used For？

RTG crane is mainly used to remove, load and unload international standard containers. Widely used in container yards, they handle light-to-medium loads for efficient stacking.

1. Container Terminal Yards: No fixed rails required, enabling flexible adjustment of operation areas. They meet the needs of container storage and transfer at terminals, efficiently completing container loading, unloading, and stacking.
2. Inland Container Transfer Stations: Smaller in scale than ports, these stations need flexible cross-area scheduling for cargo turnover. RTG’s mobility improves transfer efficiency and reduces rail construction costs.
3. Bulk/Cargo General Areas in Freight Ports: For short-distance handling of small containers and piece goods in the area, RTGs can move flexibly between bulk storage areas and loading/unloading points, adapting to multi-category cargo operations.
4. Container Loading/Unloading Areas in Industrial Parks: Serving container receipt/dispatch for multiple workshops and warehouses in the park, they can move between different workshops without site modification for fixed rails.
5. Temporary Logistics Hubs: Such as emergency material transfer stations and temporary freight sites. No long-term infrastructure is needed—RTGs can be quickly deployed to flexibly adapt to temporarily adjusted operation scopes.

RMG Gantry Crane

Rail mounted container gantry (RMG) crane is a kind of rail mounted crane used to unload, stack and load 20ft, 40ft, 45ft lSO standard containers.

They run on fixed rails, designed for container handling. With high load capacity and stable operation, they excel in dense stacking at ports or large container yards, boosting storage efficiency.
