Used across industries such as manufacturing, construction, and logistics, gantry cranes offer versatility and efficiency for lifting tasks where overhead cranes may not be feasible.
In this guide, you’ll learn what a gantry crane is, its types, how it’s made, industrial applications, and the benefits that make it an essential tool in modern operations.
Understanding the Gantry Crane
A gantry crane consists of a horizontal beam supported by freestanding vertical legs. The beam holds a trolley and hoist that travel along its length, allowing loads to be lifted and transported.
Unlike bridge cranes, gantry cranes are not fixed to a building structure. This makes them ideal for outdoor use or in facilities where installation of overhead cranes is impractical.
Key Features of a Gantry Crane
A horizontal bridge (girder) for trolley movement
Freestanding legs that support the structure
A trolley and hoist mechanism for lifting
Power and control systems for movement and operation
Types of Gantry Cranes
Gantry cranes come in a wide variety of types, each designed for specific environments, load capacities, and operational requirements.
Full Gantry Crane
This is the most common type of heavy-duty gantry crane. It has two vertical legs that move on tracks or wheels, supporting a horizontal beam. Full gantry cranes are used in shipyards, steel yards, and large manufacturing plants.
Semi-Gantry Crane
A semi-gantry crane uses one leg while the other end is supported by a runway attached to a building wall. It’s perfect for facilities with space constraints, such as machine shops or industrial plants.
Portable Gantry Crane
Designed for mobility and temporary use, these cranes are lightweight and mounted on wheels or casters. They are ideal for workshops, garages, and maintenance tasks, typically handling loads up to 5 tons.
Adjustable Gantry Crane
These cranes offer adjustable height, span, and width. They’re highly versatile and can adapt to different job requirements, making them useful in dynamic work environments.
Single Girder Gantry Crane
This crane has one main girder and is used for light to moderate lifting needs. It is more economical and easier to install than double girder designs.
Double Girder Gantry Crane
Featuring two girders, this type provides higher lifting capacity, greater span, and more stability. It’s widely used in heavy industries like mining, shipbuilding, and steel production.
Truss Gantry Crane
Truss-style gantry cranes feature a lightweight frame that reduces wind resistance, making them ideal for outdoor applications like construction and material storage yards.
Box Gantry Crane
Box girder gantry cranes are known for strength and durability. The enclosed box structure increases rigidity, supporting extremely heavy loads over long spans.
L-Shaped Gantry Crane
With L-shaped support legs, these cranes are ideal for handling long items like steel beams or piping. The shape allows for increased clearance and improved maneuverability.
U-Shaped Gantry Crane
Designed to lift and move oversized or wide loads, the U-shaped structure offers enhanced lateral clearance. Commonly used in container handling and logistics.
Workstation Gantry Crane
Light-duty gantry cranes for assembly lines, repair shops, and labs. Their small size and mobility make them suitable for repetitive lifting tasks in confined areas.
How Gantry Cranes Are Built
The manufacturing process of gantry cranes involves careful engineering of mechanical, structural, and electrical components. Each system must be optimized for the crane’s load rating and intended use.
Structural Design
The frame includes girders and supporting legs made from high-grade steel. The structure may be an I-beam, box, or truss configuration, depending on load capacity and span.
Trolley and Hoist System
The trolley runs along the beam and carries the hoist. Hoists may be electric, pneumatic, or manual. Chain hoists are used for lighter loads, while wire rope hoists handle heavy-duty lifting.
Power and Controls
Gantry cranes are powered by electricity, with power fed through festoon systems, conductor bars, or cable reels. Control methods include:
Pendant control
Radio remote control
Driver cabins (for large cranes)
Advanced control systems may feature overload sensors, programmable logic controllers (PLCs), and variable frequency drives (VFDs) for better performance and safety.
Industrial Applications of Gantry Cranes
Gantry cranes serve a broad range of industries, offering unmatched flexibility and lifting capacity.
Manufacturing and Assembly
Used to lift engines, molds, components, and raw materials. Common in automotive, aerospace, and heavy machinery sectors.
Warehousing and Logistics
Support efficient material handling from unloading docks to storage zones. Portable cranes are especially useful in space-constrained warehouses.
Shipyards and Marine Terminals
Handle large components like ship engines and containers. Gantry cranes are indispensable in vessel construction and cargo handling.
Construction Sites
Lift heavy construction materials such as concrete slabs and steel beams. They can be quickly assembled and disassembled as projects progress.
Repair and Maintenance Facilities
Portable gantry cranes assist mechanics in lifting engines or heavy parts during servicing. Their mobility makes them ideal for confined shops.
Container Handling
Specialized gantry cranes stack and move shipping containers in ports and rail yards, enhancing speed and safety in freight logistics.
Gantry Crane Load Capacities
Choosing the right crane capacity is critical for safety and productivity. Common capacity tiers include:
1–2 tons: Light-duty use in workshops
5 tons: General maintenance and fabrication
10–15 tons: Assembly lines and mid-range lifting
20–30 tons: Construction and industrial processing
50+ tons: Heavy-duty operations in shipyards and ports
Always match the crane’s capacity to the weight and frequency of your lifting needs.
Aardwolf gantry cranes are designed for full mobility, equipped with high-quality swivel casters and lockable wheels. This makes them ideal for workshops, fabrication floors, and small manufacturing facilities where equipment frequently moves.
Example:
An AGC-1500 model can be quickly rolled between workstations in a stone processing plant for lifting and positioning granite slabs without using forklifts or permanent cranes.
Aardwolf’s adjustable gantry cranes allow height and beam length adjustment, providing flexibility in environments with limited space or varied lifting requirements.
Benefits include:
Easy clearance under doorways or ducting
Ability to lift different load sizes
Customizable for specific job sites
Example:
In a countertop fabrication shop, an AGC crane is adjusted to lift marble slabs inside a low-clearance warehouse, then raised again for use near cutting equipment.
Constructed from high-strength aluminum or steel, Aardwolf gantry cranes are built to be lightweight for maneuverability yet strong enough to lift loads up to 3 tons.
Benefits:
Easier handling and setup
Corrosion-resistant frames (especially important in wet or dusty environments)
Example:
The AGC-2000 model is used in a glass handling facility, where its aluminum frame resists moisture while lifting large glass panels with vacuum lifters.
All Aardwolf gantry cranes are designed for simple, tool-assisted assembly and disassembly, making them ideal for mobile teams or multi-site use.
Advantages:
Saves time during setup
Minimizes labor required
Compact disassembly for transportation
Example:
A construction crew uses the AGC-3000 to lift HVAC equipment on-site, then quickly disassembles it and transports it to the next job location.
Aardwolf gantry cranes integrate seamlessly with the company’s full range of lifting attachments, including:
Vacuum lifters (e.g., AVLP-2 for glass and AVLP4 for stone)
Slab lifting clamps
Mechanical tongs
