A container gantry crane is a large piece of equipment widely used in ports, docks, and container yards. Its structure uses the gantry as the main frame to support the main beam and the lifting mechanism on it. Its main function is to load, unload, stack, and transport containers. VOITTO offers various types of container gantry cranes, including RTG cranes, rail-mounted gantry cranes, STS cranes, and straddle carrier cranes. These machines cater to different mobility, infrastructure, and automation requirements, enabling terminal operators and yard planners to precisely select the most suitable equipment based on throughput targets and on-site conditions.

وصف المنتج

A container gantry crane is a heavy-duty gantry lifting system purpose-built for loading, unloading, stacking, and transferring shipping containers in high-throughput environments. Unlike general-purpose gantry cranes, it is engineered around container-specific handling requirements — spreader compatibility, precise stacking positioning, and duty cycles suited to continuous terminal operation.

This equipment is widely used at container terminals, port yards, rail container yards, inland container yards, and logistics hubs. At these locations, the key challenge lies not only in lifting heavy loads, but also in the ability of container gantry cranes to quickly, accurately, and safely handle large volumes of containers within limited spaces, thereby increasing throughput at ports, terminals, and container yards.

Container Straddle Carrier Crane

A container straddle carrier spans the top of a container via its frame and uses specialized lifting gear on its underside to lift, move, and stack containers. They can navigate autonomously within a yard, enabling rapid transfer between ship loading/unloading areas, storage areas, and container trucks.

التطبيق: Users operate this equipment to perform short-distance container transport, stacking, and transshipment tasks. Applications include large container port terminals, automated container yards, rail container hubs, inland ports, and intermodal logistics centers.

الميزات: This container straddle carrier is highly flexible, offers efficient transport capabilities, and is highly adaptable. The equipment can lift and move containers directly by straddling them, reducing the need for transshipment steps required by traditional loading and unloading equipment.

الاختلافات بين رافعة RTG ورافعة RMG ورافعة STS

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.

Container Gantry Crane for Port and Terminal Operations

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.”

Buying Guide: How to Choose a Container Gantry Crane

Operators can use the following factors as a reference when selecting the appropriate container gantry crane equipment.

• Container throughput — Estimate the target hourly throughput to determine the required cycle time and assess whether a single-trolley or double-trolley configuration is more appropriate.
• Yard Size and Layout — Span requirements depend on the number of container rows and traffic lanes the crane must cover in a single travel cycle.
• Stacking Height — While higher stacking density (5–6 layers) increases storage capacity per unit area, it also requires greater lifting height and stronger anti-sway control capabilities.
• Span Requirements — The span should match the width of the container area in the yard. An excessively large span increases structural costs without providing any benefits in terms of throughput.
• Rail-Mounted (RMG) vs. Rubber-Tired (RTG) — RMGs are suitable for scenarios with fixed operating paths, high frequency, and stringent precision requirements. RTGs are suitable for yards that require flexible positioning adjustments and do not wish to invest in rail infrastructure.
• Level of Automation — Semi-automated configurations reduce reliance on operators for repetitive tasks; fully automated systems (supporting ARMG upgrades) are suitable for terminals planning to reduce labor costs over the long term.
• Operating Environment — Factors such as high humidity, dusty conditions in coastal areas, and continuous multi-shift operations should serve as key considerations when selecting corrosion protection measures and service classes (A6–A8).
