Full-Frame Single-Girder Gantry Crane
The full truss-type single-girder gantry crane is a common type of gantry crane. It is widely used in outdoor warehouses, material yards, ports, construction sites, and other scenarios due to its lightweight structure and high cost-effectiveness. It is mainly used for loading, unloading, transporting, and short-distance transfer of materials. Its core feature is the use of a “truss-type” gantry structure and single-girder load-bearing form, which combines flexibility and practicality.
Description
The fully truss-type single-girder gantry crane is a lifting device specifically designed for outdoor work scenarios. Its core advantage lies in its unique lightweight truss structure.
This structure is composed of structural steel, which not only significantly reduces the weight of the equipment and reduces the load requirements on the foundation, but also has minimal wind resistance due to its hollow design. In open-air sites such as ports, terminals, and open-air storage yards, it can maintain stable operation and avoid affecting operational safety due to strong winds.
In terms of performance, the crane adopts a single-beam load-bearing design and uses high-strength steel as the main beam material, which not only ensures structural rigidity but also provides good stability, easily meeting lifting requirements ranging from 1 to 20 tons.
With a span of 8-30m and a lifting height of 6-18m, it can be flexibly adapted to a variety of scenarios, such as cargo transfer in warehousing and logistics, raw material loading and unloading in steel processing plants, and component hoisting at construction sites.
In terms of installation and transportation, the full-frame single-girder gantry crane adopts a modular assembly model, with each component transported separately, reducing transportation costs and difficulties, and making on-site assembly more convenient and efficient.
In terms of operational performance, it is rated at A3-A5 and equipped with a variable frequency speed control system, which enables smooth adjustment of lifting and running speeds, reducing load sway. It also comes standard with safety limit devices, such as lifting height limits and running travel limits, to ensure comprehensive operational safety and efficiency.
Compared with traditional gantry cranes, fully truss-type single-girder gantry cranes are ideal for outdoor lifting operations due to their excellent ventilation, light weight, and high cost performance. Their advantages are particularly evident in situations where equipment flexibility and environmental adaptability are highly demanded.
Features
Made of structural steel, it significantly reduces the weight of the equipment, thereby reducing the load requirements on the foundation and lowering site construction costs.
Excellent aerodynamic performance: The hollow design minimizes wind resistance, enabling stable operation in open, windy environments such as ports, terminals, and open-air storage yards. This prevents strong winds from affecting operational safety and improves applicability in complex weather conditions.
Wide load capacity range: Featuring a single-beam load-bearing design and utilizing high-strength steel as the main beam material, this structure ensures both structural rigidity and excellent stability, easily accommodating lifting requirements ranging from 1 to 20 tons.
Flexible operation coverage: With a span coverage of 8-30m and a lifting height of 6-18m, it can be flexibly adapted to various scenarios such as cargo transfer in warehousing and logistics, raw material loading and unloading in steel processing plants, and component hoisting at construction sites, meeting the needs of different operation spaces.
Reliable working level: Working level is A3-A5, which can adapt to different frequencies and intensities of work tasks, balancing work efficiency and equipment durability.
Smooth speed control system: Equipped with a variable frequency speed control system, it can smoothly adjust the lifting and running speeds, reducing load swaying, protecting the lifted cargo, and improving the accuracy of operations.
Modular assembly mode: Each component can be transported separately, reducing transportation costs and difficulties, which is especially suitable for sites with limited transportation conditions. At the same time, on-site assembly is more convenient and efficient, shortening the equipment installation and commissioning cycle and enabling rapid commissioning.

Purchasing Process

FAQs About Choosing the Right Gantry Crane and Supplier
In order to obtain accurate quotes for custom overhead cranes, providing the following core information will greatly improve efficiency:
1. Key specifications: including rated lifting weight (tons), span (i.e., track spacing, meters), and lifting height (meters), which is the basis of the design.
2. Use environment and working conditions: Explain the conditions of the installation site (such as indoor/outdoor, temperature, humidity) and work level (busy level), which determines the material selection and configuration level of the structure.
3. Specific configuration requirements: clarify the drive mode (such as frequency conversion control), brand preferences for electrical components, safety devices (such as overload limiters, anti-collision systems), and whether special functions such as remote control are required.
4. Installation and service: confirm the on-site power supply conditions (voltage, frequency), installation conditions, and specific expectations for delivery time, installation and commissioning, and after-sales service.
The more detailed the information provided, the more accurate and reliable the solutions and quotations obtained.
1. Span and lifting capacity: this is the foundation.The larger the span and the higher the rated lifting weight, the material and design costs of the main beam and structure will increase significantly, and the higher the price.
2. Working level and frequency of use: The working level (A1-A8) represents the busy level and load status of the crane.Cranes with frequent and heavy-duty use require more durable motors, gearboxes and structural parts, and the cost is naturally higher than that of lightweight and occasionally used equipment.
3. Structure and configuration: The double beam is more complex and stable than the single beam structure, and the price is higher.At the same time, the lifting height, operating speed, motor brand, control system (ordinary vs frequency conversion), and the level of safety devices (such as anti-swing, load monitoring) all directly affect the final quotation.
4. Degree of customization and brand service: completely standard models have lower costs.The customized design based on the workshop environment (such as explosion-proof and high temperature), special processes (such as metallurgical special), brand added value, and after-sales guarantee system will all be reflected in the price.
In simple terms, when buying a bridge crane, it is necessary to consider “how much, how frequently, what environment and what configuration”, which determine its core value and price.
Which crane to choose mainly depends on your specific needs. You can quickly judge from the following four core aspects:
-Single-beam bridge crane: it is suitable for conventional workshops with light and medium loads (usually ≤20 tons), medium span, and low frequency of use. It is the most economical and versatile choice.
-Double-girder bridge crane: used for heavy-duty, long-span, or high-work-level occasions (such as frequent hoisting, metallurgy, heavy-duty assembly). Its stability, durability, and safety are higher, but the cost is also increased accordingly.
-Free vertical crane (cantilever/column type): suitable for fixed working points and working conditions with limited rotation range, such as beside machine tools, maintenance areas, or production line stations, it can efficiently use corner space and be installed flexibly.
-Grab crane: It is specially used for the handling, loading, and unloading of bulk materials (such as grain, coal, sand, and gravel). The only reason to choose it is that you need to deal with such unpackaged loose materials.
In simple terms, you can filter according to this logic:
First, according to the lifting weight and span, choose between a single beam and a double beam.
If the scope of operation is highly concentrated and the space is limited, consider a free vertical.
If the handling object is bulk material, it points directly to the grab type.
Delivery times largely depend on whether the crane is standard or customized. Based on our experience, standard single-girder and double-girder cranes can be produced more quickly, while cranes with special spans, duty ratings, or environmental requirements naturally require additional engineering design time.
