Gantry Crane Customization
When it comes to lifting heavy materials efficiently, gantry cranes offer a dependable solution. Whether you're handling steel beams in a fabrication shop or managing container loads in an outdoor yard, choosing the right gantry crane can make your daily operations smoother—and safer.
Gantry cranes with capacities ranging from 0.5 ton to 100 ton are commonly used in a variety of settings, including:
- Manufacturing plants
- Structural steel and welding workshops
- Shipbuilding and marine yards
- Warehouses and distribution centers
- Hydropower, thermal, and nuclear plants
- Outdoor construction or assembly zones
Why Customization Matters for Your Gantry Crane
Not all gantry cranes are built the same. In fact, they shouldn't be. Your lifting needs vary based on your materials, floor space, hook height requirements, and how often the crane runs during a shift. That's why customization is not a luxury—it's essential.
Here's what customization helps with:
- Matching crane specifications to your actual working conditions
A 3-ton crane in a confined indoor space has very different needs than a 50-ton crane operating in an open-air shipyard. - Reducing operational delays
When the crane fits your layout, lifting happens more smoothly, with fewer adjustments and workarounds. - Improving safety and control
A properly selected hoist and travel system minimizes sway and unexpected movement, especially with longer loads.

If you're in the market for a gantry crane—or planning to upgrade an existing one—this guide will help you ask the right questions, avoid common pitfalls, and make a purchase decision with confidence.
Girder Customization: Select Structure for Capacity and Use
The girder is the main load-bearing structure of your gantry crane. Choosing the right girder type is the first step in making sure your crane performs well and lasts long. It affects not only how much your crane can lift but also how high it can lift, how far it can span, and how it behaves under real working conditions. Let's break down the four most commonly used girder types for gantry cranes—and how to match them to your job.
Single Girder
If you're working with lighter loads and want a more economical solution, single girder gantry cranes are often the way to go.
- Typically used for lifting capacities from 0.5 ton to 20 tons
- Lighter self-weight, which can reduce support structure and cost
- Easier and quicker to fabricate and install
- Ideal for general-purpose material handling in workshops, warehouses, and assembly areas
- Can be used with electric chain hoists or wire rope hoists mounted on a trolley
This design is compact and efficient, especially for facilities with limited headroom or moderate lifting cycles.
Double Girder
For heavier loads or longer spans, double girder cranes offer the strength and performance needed for tougher work environments.
- Commonly selected for capacities ranging from 10 tons to 100 tons
- Provides higher hook height since the hoist is mounted between the girders rather than below
- Suitable for longer spans, such as those needed in fabrication yards or heavy equipment shops
- Can accommodate open winch trolleys, which are essential for high-duty applications
- Better suited for frequent, heavy-duty lifting in demanding industrial operations
While more complex and costly than single girder models, they provide better flexibility and lifting power for larger-scale operations.
Box Girder
Box girders are a specialized option designed for high performance and stability. They are especially useful where precision and structural integrity matter most.
- Made from closed, welded steel sections for superior strength and torsional resistance
- Used in cranes with long spans, high loads, and tight deflection requirements
- A go-to choice in industries like power generation, bridge construction, and shipyards
- Compatible with heavy hoists and automation systems
This type of girder is typically part of a double girder crane configuration and can be customized in size and wall thickness to match specific lifting needs.
Truss Girder
Truss girders are built for environments where wind and weather play a major role. You'll often see these in outdoor installations.
- Constructed with triangular lattice structures, making them lightweight but strong
- Provide good performance against side winds and outdoor conditions
- Best suited for long-span, low- to medium-capacity gantry cranes
- Frequently used in precast concrete yards, container handling, and shipbuilding areas
- Easy to maintain and visually open, making inspections straightforward
Keep in mind, truss girders are not designed for extremely heavy loads but are ideal when weight, wind, and mobility need to be balanced.
Practical Tips for Buyers
Choosing a girder isn't just about capacity. It's about how and where the crane will work.
- Lifting Capacity: Match the girder strength to the heaviest load you expect—plus a safety margin
- Duty Frequency: For frequent lifting or long hours, go with box or double girders for durability
- Span and Height Requirements: Longer spans and higher lifts generally call for stronger girders
- Site Environment: Use truss girders for outdoor work and box girders for precision applications
Selecting the right girder up front prevents costly design changes later—and ensures your gantry crane is built for the job you actually need it to do.
Span Customization: Define Your Coverage
When choosing or designing a gantry crane, one of the most critical dimensions you'll need to define is the span—that is, the distance between the two supporting legs of the crane. This measurement directly affects how much floor area the crane can cover and how efficiently it can move loads within your workspace. Put simply, if the span is too short, you limit your working width. If it's too wide for your site or structure, installation becomes complicated, and the crane may lose stability or cost more than necessary.
How to Determine the Right Span
Every workshop, yard, or construction site is laid out differently, so there's no one-size-fits-all span. You need to think through your operating area and lifting workflow before locking in your numbers.
Key factors to consider include:
- Building or site width: The span should allow the crane to reach the full usable area without hitting walls or obstructions.
- Rail or track layout: For rail-mounted cranes, check if the rail foundations are already fixed or if you can adjust placement.
- Clearance zones: Consider the space needed for operator movement, forklifts, and nearby equipment.
- Obstacles in the work area: Include columns, walls, pipes, or electrical lines in your planning.
- Crane type and load behavior: Heavier loads and longer spans increase the need for stronger girders and precise balance.
Planning Ahead: Think Beyond Today's Setup
While your current layout is important, also consider how your needs might grow or change in the next few years. A span that fits today's operation might fall short if you expand your production line or rearrange your facility.
Here are a few tips to keep in mind:
- Leave buffer zones on each end if your crane needs to load/unload from vehicles or storage racks.
- Check for possible expansion of your runway or building—will the crane still work if you add more bays?
- Avoid customizing a span too tightly; it's better to allow a little extra width than be forced into a redesign later.
Final Advice for Crane Buyers
Before finalizing your crane's span:
- Measure your usable floor space carefully—not just total building width
- Review any existing crane rails or install locations with your contractor or engineer
- Ask about clearance requirements specific to the hoist and trolley system
- Discuss future layout changes with your crane supplier—they may recommend a modular or extendable design
Getting the span right from the start ensures smooth operation, prevents structural interference, and gives your gantry crane the flexibility to grow with your business.
Cantilever Options: Extended Reach When Needed
Sometimes, the standard setup of a gantry crane—where the load moves between the two supporting legs—is not enough. That's where cantilever extensions come into play. A cantilever allows part of the crane to extend beyond its legs, giving you extra reach and flexibility.
Cantilevers can be designed as either single-sided or double-sided cantilever gantry cranes depending on your needs:
- Single-sided cantilever: Extends on one side only, useful when you need to load or unload from one direction, such as over a truck or loading dock.
- Double-sided cantilever: Extends equally on both sides, providing extra reach on both ends. This is common when your operation requires loading or unloading on either side of the crane.
When to Consider Cantilever Extensions
Adding a cantilever is practical when your lifting needs extend beyond the basic footprint of your crane legs. For example:
- You need to lift and place loads outside the edge of your runway or rails
- Your loading and unloading points are positioned away from the crane supports, such as beside a truck, railcar, or storage area
- Space constraints require you to minimize the size or number of legs while maximizing reach
- Your operation requires extra clearance for vehicles or equipment moving under the crane
What You Should Keep in Mind
While cantilevers add versatility, they also increase structural demands on your crane. The longer the extension, the more stress on the girder and legs, which means your crane needs to be designed accordingly.
Here are some practical points to consider:
- Cantilever length is usually limited to a percentage of the total span—commonly 10% to 20%—to maintain stability
- Longer cantilevers may require additional reinforcement on the girder or supporting legs
- Be aware that adding cantilevers can increase the crane's overall footprint, so plan for extra clearance on the floor
- The crane's travel system and hoist trolley must be capable of safely operating over the cantilevered section
Buyer Tip
If your workflow involves loading/unloading beyond your crane's leg supports or requires reaching into tricky spots, a cantilevered design is worth considering. Always discuss your specific layout and load patterns with your crane supplier to determine the safest and most cost-effective cantilever length.
A well-planned cantilever can improve productivity by reducing the need for additional equipment or manual handling—and help you get the most out of your gantry crane investment.
Height Configuration: Total vs. Lifting Height
Height is a critical dimension when customizing your gantry crane. Getting it right means your crane will operate safely and efficiently without unnecessary restrictions or risks.
There are a few key height measurements to keep in mind:
- Total Height: The overall height from the ground up to the highest point of the crane structure, including the girder and supporting legs. This is important for fitting the crane within the building or site environment.
- Under-beam Clearance: The clear vertical space available below the crane girder for the load to move freely. This must be enough to safely accommodate the largest load you plan to lift, plus any rigging or slings.
- Hook Travel Distance: How far the hook can move vertically, from the lowest point to the highest lifting position. This determines your maximum lifting height and how you handle different load sizes.
Why These Heights Matter
If your crane is too tall, it may interfere with overhead structures such as ceilings, lighting, pipes, or cranes in adjacent bays. On the other hand, if the lifting height is too low, you might struggle to position loads properly or handle tall items safely.
You want to make sure there is enough clearance not just for the load, but also for rigging hardware, slings, or any lifting attachments you use below the hook.
Practical Considerations
When deciding on your crane's height setup, keep these points in mind:
- Measure the maximum height of your loads, including any slings or spreaders attached.
- Consider operator access and safety—there should be enough space for personnel to work around and under the crane safely.
- Account for any overhead obstacles like lighting fixtures, ventilation ducts, or fire suppression systems.
- If your facility has multiple cranes or equipment, ensure your gantry crane won't clash with others when operating at full height.
Buyer Tip
Don't just think about the load itself—always include the extra space needed for slings and rigging gear when specifying hook height. Also, make sure there's safe clearance for operators and maintenance access. Taking these factors into account early will save you from costly adjustments and downtime later on.
Setting the right height means your crane will be a better fit for your space and tasks, improving productivity and safety every day.
Supporting Leg Design: Match Structure to Site Layout
The design of the gantry crane's supporting legs is just as important as the girder and hoist. Legs hold the entire structure up and affect how the crane fits into your workspace. Choosing the right leg style helps maximize your operational space and makes daily tasks easier. Let's look at some common leg designs and when each one makes sense.
A-Frame Legs
A-frame legs are the most traditional and straightforward design.
- Simple, strong, and rigid structure
- Commonly used for portable cranes or fixed indoor gantries
- Easy to manufacture and maintain
- Provides stable support but can take up more floor space compared to other designs
This design is great for workshops or yards where you have enough room around the crane and want a reliable, no-fuss setup.
U-Frame Legs
U-frame legs offer a wider opening underneath the crane, which is useful in busy environments.
- Provides greater vertical clearance between the legs
- Allows forklifts, trucks, or other vehicles to pass safely under the crane without obstruction
- Often used in warehouses, loading docks, or manufacturing floors where multiple types of equipment operate side by side
If you need to keep your workspace flexible for different types of traffic, U-frame legs are a solid choice.
L-Frame Legs
L-frame legs are designed for space-limited or one-sided operations.
- Compact design, ideal for placing the crane close to walls or other structures
- Common in workshops or narrow aisles where you want to maximize floor area
- Supports crane operations mainly from one side, perfect for loading or unloading along a wall
If your operation requires efficient use of tight spaces, L-frame legs help you keep the crane footprint small without sacrificing function.
Custom Legs
Sometimes, standard leg designs aren't enough—especially if you need portability or specific environmental protections.
- Options include foldable legs for easy transport and storage
- Telescoping or adjustable-height legs to adapt to uneven floors or different lifting heights
- Outdoor legs can be treated with anti-corrosion coatings like galvanizing or special paint to withstand weather and humidity
Custom legs allow you to tailor the crane to unique site challenges or workflow requirements.
Buyer Tip
When selecting your gantry crane legs, think carefully about:
- How much floor space you have available
- Whether forklifts, trucks, or people need to move underneath
- If your site is indoors or outdoors, and whether weather protection is needed
- Your need for portability or height adjustment
Matching the leg design to your actual site conditions will make your crane easier to use, safer, and better integrated into your workflow.
Travelling Mechanism: Mobility to Match Your Operation
How your gantry crane moves around your workspace can make a big difference in efficiency and safety. The travelling mechanism determines whether your crane is fixed, semi-mobile, or fully portable—and it needs to fit your site conditions and lifting demands.
Let's explore the main types of travelling systems and when each one works best.
Rail travelling is the most common setup for permanent, heavy-duty gantry cranes.
- The crane moves smoothly along rails fixed to the ground or runway beams
- Provides precise and stable travel, which is critical when handling heavy loads from 10 to 100 tons
- Ideal for factories, shipyards, or warehouses with a dedicated, well-prepared runway system
- Requires upfront investment in installing rails but delivers reliable, repeatable performance over the long term
If your operation involves frequent heavy lifts over the same path, rail travelling offers the best combination of safety and control.

- Wheels can swivel, making it easy to maneuver the crane by hand or with minimal power assistance
- Works best on smooth, flat floors such as polished concrete or factory slabs
- Ideal for shops or maintenance areas where the crane needs to be moved occasionally to different locations
This option offers great flexibility but is not suited for heavy loads or rough surfaces.
Rubber Tyred Wheel Travelling Gantry Cranes- Single Girder RTG Gantry Crane VS. Double Girder RTG Crane , Vs. U Frame RTG Crane
Wheel travelling systems use fixed or steerable wheels made from rubber or steel to move cranes around.
- Suitable for semi-permanent or outdoor gantries in the 5 to 50-ton range
- Rubber-tyred wheels are common on concrete floors, providing good grip and less floor damage
- Steel wheels are more durable on rougher or uneven surfaces like asphalt or gravel
- This system offers more mobility than rail travelling but requires solid floor surfaces to handle wheel loads
Wheel travelling gantries are popular in construction yards, precast plants, and outdoor storage areas where fixed rails are impractical.
Buyer Tip
When choosing your crane's travelling mechanism, consider these factors carefully:
- How heavy are your typical loads and how often will the crane travel?
- Is your floor surface smooth, uneven, indoor, or outdoor?
- Can you invest in rail installation, or do you need a more portable option?
- What kind of maneuverability do you require within your workspace?
Selecting the right travel system upfront prevents operational headaches and helps keep your material handling smooth and safe.
