A container gantry crane is a category that includes several structural configurations — each suited to different terminal layouts, budgets, and automation goals. The comparison below is built for procurement teams evaluating mobility, infrastructure investment, and throughput trade-offs before specifying equipment.
| Comparison Mode | RTG | RMG | STS | Straddle Carrier Crane |
|---|---|---|---|---|
| Structural Features | Supported by rubber tires, with truss or box-type main girder, spanning multiple rows of containers. | Runs on fixed rails, mainly double-girder structure with high rigidity and stability. | Features a tall gantry with a luffing jib, extending over the sea from the quay. | A mobile wheeled carrier with a U-shaped frame structure, designed to straddle containers and lift them using a spreader mounted beneath the top frame. |
| Mobility | Tire-driven, capable of free steering in yards, suitable for flexible movement. | Moves linearly along laid rails, with mobility limited to rail paths. | Fixed on quay-side rails, only movable along the shoreline. | Highly mobile with rubber tires, capable of independent driving, turning, and transferring containers between different operational areas without fixed tracks. |
| Lifting Capacity | Typically 35-70 tons (container-specific), suitable for single-container lifting. | Similar to RTG (35-70 tons), but with stronger load stability due to fixed rails. | Capacity exceeds 60 tons, capable of lifting double containers. | Typically 30-80 tons, suitable for handling 20ft, 40ft, and 45ft containers, with some heavy-duty models supporting twin-container operations. |
| Span Range | Span of 20-35 meters, covering 4-6 rows of containers + traffic lanes. | Larger span (30-50 meters), ideal for dense yard layouts. | Span usually 40-70 meters, with jib outreach of 30-45 meters to cover the full width of ships. | No fixed span limitation. The frame width is designed according to container dimensions, allowing direct access between container rows and flexible yard layouts. |
| Application Scenarios | Container yards, logistics centers, suitable for scenarios requiring frequent position changes. | Large container terminals, professional yards, suitable for high-frequency operations with fixed routes. | Dedicated to quay sides, responsible for loading/unloading containers between ships and terminals. | Container terminals, intermodal yards, railway terminals, inland container depots, and logistics parks require transport and stacking operations. |
| Operation Efficiency | Single-container efficiency: 25-35 cycles/hour, high flexibility but lower positioning accuracy. | Efficiency: 30-40 cycles/hour, precise rail positioning for assembly line operations. | Highest efficiency: 40-60 cycles/hour (higher with double-container handling), core equipment for ship-to-shore operations. | Efficiency: 20-40 cycles/hour depending on operation mode, providing fast container transfer between quay cranes, trucks, and storage areas. |
| Flexibility | High, movable anywhere in the yard for multi-zone operations. | Medium, limited to rail range; requires auxiliary equipment for inter-rail connection. | Low, fixed on the quay with only shoreline-direction adjustment. | It can stack up to four layers high, and a single machine can handle the lifting, handling, and stacking of containers. |
| Infrastructure Cost | No rail laying needed, low initial investment with simple site leveling. | Requires rail laying and foundation treatment, higher infrastructure cost than RTG. | Most complex structure, highest infrastructure cost, requiring supporting quay facilities. | Lower infrastructure investment compared with RTG/RMG/STS because it mainly requires a flat operating surface. |
| Power Source | Diesel engine-driven (traditional) or electric (in new energy transition). | Mostly electric-driven via cables or sliding contacts, more environmentally friendly. | Mostly electric-driven, some with energy storage systems for high-power operations. | Available in diesel, hybrid, and fully electric configurations, providing flexible energy solutions for different terminal requirements. |
In port and terminal operations, container throughput directly determines berth productivity and yard turnaround time. If container gantry cranes are properly laid out within the yard, they become more than just lifting equipment—they serve as a key lever for directly boosting terminal efficiency.
For terminal operators evaluating new equipment or upgrading their capacity, the core considerations during the selection process often lie not in “how much lifting capacity the equipment has,” but rather in “how high an hourly container throughput this configuration can sustain, and how well it can be scaled for automation.”
Operators can use the following factors as a reference when selecting the appropriate container gantry crane equipment.
