INTRODUCTION

The Rubber-Tyred Container Gantry Crane (RTG) is a specialized mobile gantry crane designed for high-density container handling and stacking in port container yards, inland freight hubs, and intermodal logistics terminals. Engineered to move smoothly on heavy-duty rubber tires without the constraints of fixed ground rails, the RTG crane offers unmatched operational flexibility, rapid cross-yard mobility, and exceptional productivity.

APPLICATION SCENARIO

Seaport Container Yards: Deployed in high-throughput maritime ports (such as deep-water container terminals in Lagos or Karachi) for fast yard transfer between internal transport vehicles and container stacks.
Inland Container Depots (ICDs) & Dry Ports: Utilized in multimodal logistics hubs to manage container storage, sorting, and truck loading operations away from the immediate coastline.
Large-Scale Freight Logistics Parks: Applied in regional distribution centers requiring high-density stacking and systematic organization of heavy shipping containers.

ADVANTAGES

High Yard Mobility and Flexibility: Equipped with advanced multi-wheel steering systems, RTGs can pivot, travel smoothly across paved surfaces, and relocate between different container storage blocks.
Maximized Storage Density: Optimizes terminal footprint by stacking containers up to 1-over-6 high and spanning multiple rows wide, substantially increasing vertical storage capacity.
Multi-Block Operational Versatility: Unlike rail-mounted gantry (RMG) cranes restricted to a single fixed runway, RTGs can freely transition across the entire yard to respond to shifting logistics bottlenecks.
Eco-Friendly Automation Readiness: Modern units feature regenerative braking, variable speed diesel engines, and automated gantry steering to lower fuel consumption and emissions.

FAQS

01What is the main difference between an RTG Crane and an RMG Crane?

The primary difference lies in mobility and rails. An RTG (Rubber-Tyred Gantry Crane) runs on rubber tires and can change lanes or move between different yard blocks without fixed ground rails. An RMG (Rail-Mounted Gantry Crane) operates strictly on fixed steel rails, offering higher automation potential and larger spans, but lacks cross-block mobility.

02What are the power supply options for RTG cranes (Diesel vs. E-RTG)?

Standard Diesel Generator: Fully independent and self-powered, ideal for yards without power grid infrastructure. E-RTG (Electric RTG): Powered via cable reel or busbar (overhead conductor rail). It drastically lowers operating costs, maintenance, and noise while eliminating direct emissions. Hybrid RTG: Combines a smaller diesel engine with battery/supercapacitor storage to capture braking energy, reducing fuel consumption by 30%-50%.

03What is the standard lifting capacity and stacking height of a container RTG crane?

The standard rated capacity under spreader is typically 40.5 tons to 50 tons (suitable for single 20ft/40ft containers or twin 20ft containers). Stacking heights are commonly 1-over-5 (stacking 5 high) or 1-over-6 (stacking 6 high).

04Can the RTG crane switch between container handling and bulk cargo handling?

While RTG cranes are primarily specialized for ISO containers using automatic hydraulic spreaders, they can be equipped with quick-change hooks or specialized attachments to handle oversize cargo, flat racks, or heavy industrial modules.
