Gantry Crane

Gantry cranes are widely used when the lifting is needed without the cost of a building or support steel work. The gantry cranes can be placed indoors or outdoors, used for activities in steel stock yards, pre-cast segment yards, construction sites and other outdoor application.

One or two beam is supported on steel legs, on beam, there is a trolley to lift and move across, and the whole structure seems like a big gate, we call it Gantry Crane. Gantry crane is a variant of bridge crane. Gantry cranes are widely used when the lifting is needed without the cost of a building or support steel work.

Applications of gantry cranes

Shipping and Port Operations

• Container Handling: Rubber-tired gantry cranes (RTGs) and rail-mounted gantry cranes (RMGs) are pivotal in ports for loading/unloading shipping containers from vessels and stacking them in yards.
• Shipyards: Used to assemble ship components, move engines, and handle large sections during construction or repair.

Manufacturing and Industrial Facilities

• Assembly Lines: Lift and position heavy machinery, molds, or components in automotive, aerospace, and machinery manufacturing.
• Steel Mills/Foundries: Transport molten metal, raw materials, or finished steel products.
• Power Plants: Install and maintain turbines, generators, and transformers.

Construction and Infrastructure

• Bridge Building: Position heavy segments like girders or precast concrete during construction.
• Urban Projects: Lift materials (e.g., steel beams, pipes) at high-rise or large-scale construction sites.

Logistics and Warehousing

• Warehouse Management: Move pallets, machinery, or bulk goods in large storage facilities.
• Rail Terminals: Load/unload railcars with containers, heavy equipment, or industrial goods.

Specialized and Heavy Industries

• Mining: Handle ore, equipment, and machinery in processing plants or open-pit operations.
• Scrap Recycling: Sort and transport metal scraps, cars, or industrial waste.
• Wind Energy: Assemble and install wind turbine towers, blades, and nacelles.

Automotive and Transportation

• Vehicle Assembly: Move engines, chassis, or entire vehicles during production.
• Maintenance Workshops: Lift engines, transmissions, or heavy parts for repairs.

Smaller-Scale Applications

• Workshops: Portable gantry cranes for lifting engines, machinery, or materials in repair shops.
• Agriculture: Occasionally used for handling large equipment or storage units.

Advantages of gantry cranes

• Custom Crane Design: DQCRANES gantry cranes can be customized in span, height, lifting capacity (from 1 ton to 500+ tons), and mobility (fixed, portable, rail-mounted, or rubber-tired).
• Material Adaptability: Options for indoor/outdoor use, corrosion-resistant coatings for harsh environments (e.g., ports, steel mills), and specialized hooks/clamps for unique loads (e.g., containers, wind turbine blades).
• Advanced Safety Features: Overload protection, anti-collision systems, emergency stops, and fail-safe brakes to prevent accidents.
• Reduced Labor Costs: Automates heavy lifting, minimizing manual labor and speeding up workflows.
• Low Maintenance: Robust designs with easy-to-service parts (e.g., modular components, accessible motors) reduce downtime and lifecycle costs.
• Portable Gantries: Lightweight, collapsible designs for workshops or temporary sites.
• Rail/Rubber-Tired Mobility: Rail-mounted gantries (RMGs) optimize warehouse space, while rubber-tired gantries (RTGs) offer flexibility in ports and yards.
• Automation: Compatibility with smart systems for remote monitoring, predictive maintenance, and automated load tracking.
• Global Certifications: Built to meet international standards (e.g., ISO, FEM, DIN) for quality, safety, and performance.
• Comprehensive Services: Installation, training, maintenance contracts, and spare parts availability to ensure seamless operation.

Full gantry crane vs. Semi gantry crane

First, normally, gantry cranes are divided into full gantry crane, semi-gantry crane, gantry crane with cantilever, gantry crane without cantilever. Their functions are as below:

• Full-gantry crane: The main beam has no overhang, and the trolley is carried out within the main span.
• Semi-gantry crane: The height difference of the legs can be determined according to the site construction requirements.

Double girder gantry crane vs. Single girder gantry crane

Double girder gantry crane vs. Single girder gantry crane

The most common form of double girder gantry crane structure, its structural force and the effective use of the site area are reasonable.Double girder gantry cranes have strong bearing capacity, large span, overall stability, and many varieties, but their own quality is larger and their cost is higher compared with single-girder gantry cranes with the same weight. According to the different main beam structure, it can be divided into two forms of box beam and truss. At present, generally more box-shaped structure.

Single girder gantry crane of structure is often chosen by site constraints.The single girder gantry crane has a simple structure, is easy to manufacture and install, and has a small mass of its own. The main beam is mostly an off-track box-shaped structure. Compared with double-girder gantry cranes, the overall stiffness is weaker. Therefore, when the weight Q≤50t and the span S≤35m, this form can be used. Single-gantry gantry cranes have L-shaped and C-shaped door legs. The L-shape is easy to manufacture and install, and the stress conditions are good. The quality of the L-shape is small. However, the space for lifting cargo through the legs is relatively small. The C-shaped legs are made to be inclined or curved so as to have a large lateral space for the cargo to pass through the legs.

Box girder gantry crane vs. Truss gantry crane

• Box type: The use of steel plates welded into a box structure, with high safety, stiffness and other characteristics. It is generally used for gantry cranes with large tonnage and oversized tonnage. As shown in the right figure, MGhz1200 has a lifting capacity of 1,200 tons and is the largest gantry crane in China. The main beam adopts a box girder structure. The box girder also has the disadvantages of high cost, heavy self, and poor wind resistance.
• Truss type: The structural form welded by angle steel or I-beam has the advantages of low cost, light weight, and good wind resistance. However, because of the large number of welding points and the defects of the trusses themselves, the truss beams also have the drawbacks of large deflection, low rigidity, relatively low reliability, and frequent detection of welding spots. Suitable for sites with low safety requirements and low lifting weight.

Portable gantry crane vs. Rail mounted gantry crane

Gantry cranes also can be grouped into different crane types, in terms of gantry designs, including:

• Adjustable gantry cranes is designed for warehousing applications, where the movement of materials is required to go through aisles, doorways, around obstacles, and over or under obstructions. Adjustable gantry crane is often used to lift parts and equipment into position in welding shops, fabrication shops and etc.
• Portable gantry crane is flexible, which can be replaced and relocated, which is featured as fast, easy movement to and from a work site.
• Rail mounted gantry crane is used for transferring heavy loads, manually or motorized, over a fixed route.
