When it comes to container handling and industrial lifting solutions, gantry cranes are among the most versatile and efficient types of equipment. They are widely used in ports, container yards, rail terminals, and various industrial facilities. However, not all gantry cranes are created equal, and one of the key distinctions lies between fixed gantry cranes and mobile container gantry cranes.
Understanding the differences between these two types of cranes is critical for businesses aiming to invest in the right equipment for their specific needs. This article provides a detailed comparison of fixed gantry cranes and mobile container gantry cranes in terms of design, functionality, mobility, applications, cost, and maintenance requirements.
What is a Fixed Gantry Crane?
A fixed gantry crane, also known as a stationary gantry crane, is a crane system with support legs that are mounted to a fixed track or bolted directly to the floor or foundation. These cranes typically operate along a set path and are ideal for repetitive lifting tasks in a designated area.
Key Features:
-
Fixed in one location (though may move on rails).
-
Usually powered by electricity via cable reels or festoon systems.
-
Commonly used in workshops, warehouses, and production yards.
-
High load capacity and custom span/lifting height options.
What is a Mobile Container Gantry Crane?
A mobile container gantry crane, often referred to as a rubber tyred gantry RTG crane, is a mobile crane used primarily in intermodal yards and container terminals for stacking and transporting containers. These cranes are mounted on rubber tyres and can travel freely over the yard surface without being restricted to rails.
Key Features:
-
High mobility with diesel or electric power.
-
Can move in multiple directions (crab steering, 90° steering, carousel, etc.).
-
Suitable for container stacking in multiple rows.
-
Ideal for outdoor applications and container handling logistics.
Comparison: Fixed Gantry Cranes vs Mobile Container Gantry Cranes
1. Mobility
Fixed Gantry Cranes:
-
Designed to move along a fixed path (rails or a stationary base).
-
Movement is limited to longitudinal travel if rails are installed.
-
Not suited for work environments that require frequent relocation.
Mobile Container Gantry Cranes:
-
Highly mobile and flexible due to rubber tyres.
-
Can move around a facility or yard without the need for tracks.
-
Best suited for applications where the crane needs to reach multiple container stacks across a large area.
Verdict: Mobile container gantry cranes offer superior mobility and flexibility.
2. Design & Structure
Fixed Gantry Cranes:
-
Heavier, more robust structures with rigid support.
-
May include cantilever arms or custom spans for specific applications.
-
Tailored for permanent installations.
Mobile Container Gantry Cranes:
-
Tall, wide-span structures with adjustable lifting frames.
-
Designed for outdoor durability and heavy-duty container operations.
-
Typically larger and more complex in construction.
Verdict: Both crane types are structurally strong, but mobile container gantry cranes are designed for container-specific tasks with modular mobility in mind.
3. Applications
Fixed Gantry Cranes:
-
Used in manufacturing plants, fabrication yards, and warehouses.
-
Ideal for lifting heavy machinery, large steel components, precast concrete, or other bulky materials.
-
Best suited for repetitive, controlled lifting operations in a confined zone.
Mobile Container Gantry Cranes:
-
Primarily used in ports, intermodal terminals, and container yards.
-
Designed for stacking, transporting, and organizing shipping containers.
-
Can handle up to 40-65 tons per container and stack containers 3–6 high and 6+ wide.
Verdict: Fixed rail mounted gantry cranes are versatile for industrial use, while mobile container gantry cranes dominate in the logistics and shipping sectors.
4. Power and Control Systems
Fixed Gantry Cranes:
-
Often powered by electric systems (via cable reel, busbar, or festoon).
-
Controlled through a pendant control, radio remote, or cabin.
Mobile Container Gantry Cranes:
-
Usually powered by diesel generators or hybrid electric-diesel systems.
-
May include regenerative braking and energy-saving technology.
-
Remote control, operator cabin, and smart automation features are common.
Verdict: Mobile gantry cranes are technologically advanced and energy-optimized but may require more fuel or hybrid systems for movement.
5. Installation and Setup
Fixed Gantry Cranes:
-
Requires a solid foundation or rail system.
-
Installation is more time-consuming due to anchoring and structural considerations.
-
Once installed, not easily relocated.
Mobile Container Gantry Cranes:
-
No need for rails or fixed infrastructure.
-
Easier to deploy and reposition across the facility.
-
Ideal for operations that evolve or change layout frequently.
Verdict: Mobile cranes win in terms of quick deployment and operational flexibility.
6. Cost Considerations
Fixed Gantry Cranes:
-
Lower upfront cost in many cases.
-
Economical for single-area lifting.
-
Maintenance and operating costs tend to be lower due to simpler mechanisms.
Mobile Container Gantry Cranes:
-
Higher initial investment.
-
Greater complexity and mobility add to the cost.
-
Maintenance of tyres, engines, and steering systems can be more expensive.
Verdict: Fixed gantry cranes are generally more budget-friendly unless mobility is essential.
7. Maintenance and Durability
Fixed Gantry Cranes:
-
Fewer moving parts and less wear on components.
-
Long lifespan with proper maintenance.
-
Simple structure leads to less downtime.
Mobile Container Gantry Cranes:
-
Complex systems require regular servicing.
-
Diesel engines, tyres, and electronic steering demand more attention.
-
Exposed to outdoor elements, so corrosion protection and weatherproofing are critical.
Verdict: Fixed cranes are easier to maintain, while mobile cranes need a dedicated maintenance plan.
Conclusion: Which Crane is Right for You?
Choosing between a fixed gantry crane and a mobile container gantry crane depends entirely on your operational needs.
-
Choose a Fixed Gantry Crane if:
-
Your lifting tasks are confined to a specific area.
-
You need a reliable, economical solution for heavy lifting.
-
You have an established facility layout with consistent workflow.
-
-
Choose a Mobile Container Gantry Crane if:
-
Your operations involve container handling and yard mobility.
-
Flexibility and the ability to move across various lanes and blocks are essential.
-
You need to stack containers efficiently and handle high throughput in a dynamic environment.
-
Each crane type has its own strengths and ideal use cases. By carefully analyzing your current and future operational requirements, you can select the crane that delivers maximum efficiency, safety, and return on investment.
