Двухбалочные козловые краны европейского типа
The core advantages of European-style double-girder gantry cranes lie in their “precision, efficiency, energy efficiency, and flexibility,” making them particularly suitable for small and medium-sized lifting applications with high requirements for space, precision, and environmental protection. Compared to traditional heavy-duty gantry cranes, they can maintain operational efficiency while reducing site constraints and operational costs, making them an ideal choice for lightweight lifting needs in modern industrial and logistics field.
• Crane Capacity: 5ton-320ton
• Working Class: A3, A4, A5, A6, A7
Description
1. The European-style double-girder gantry crane is a type of gantry crane.
2. The term “European-style” does not refer to a geographical region but rather denotes lightweight, modular, high-precision lifting equipment designed according to European standards.
3. Compared to traditional Chinese-style cranes, it focuses on a “compact structure + high-performance” design.
4. The main beam features a double-girder design (typically box-type beams or optimized H-section steel beams), while the legs form a gantry frame structure.
5. The crane moves along ground tracks via the main hoist travel mechanism, while the trolley (equipped with a hoisting mechanism) traverses the main beam horizontally, enabling three-dimensional cargo handling.
6. Its design complies with EU FEM standards or international ISO standards, focusing on material utilization, energy consumption control, and human-machine interaction, and is widely applicable to modernized operational scenarios such as automated production lines and smart warehouses.
Features
1. Using high-strength low-alloy steel (such as Q355B), the main beam, end beam, and other structures are optimized through finite element analysis. With the same lifting capacity, the self-weight is 15%-30% lighter than traditional cranes, resulting in lower load requirements for tracks and foundations and reduced infrastructure costs.
2. The lifting mechanism, trolley running mechanism, and other core components are highly integrated (e.g., compact motors and three-in-one reducers are used), reducing space requirements and making them particularly suitable for scenarios with limited factory height or span.
3. Standard variable frequency speed control system, with smooth adjustment of lifting, trolley, and crane running speeds (e.g., lifting speed 0.1-10 m/min), avoiding start-stop impact. This not only improves operational precision (positioning error can be controlled within ±5 mm) but also reduces energy consumption by more than 30%.
4. Some high-end models are equipped with PLC control systems and human-machine interfaces, supporting remote monitoring, fault diagnosis, and even connection to factory MES systems to achieve automated interconnection.
5. Key components (such as bearings, motors, and brakes) are mostly sourced from international brands (such as Siemens and SEW), with a service life of over 100,000 hours. Structural components undergo shot blasting rust removal and long-lasting anti-corrosion treatment, making them suitable for harsh environments with high dust levels and humidity.
6. Modular design facilitates component replacement. Routine maintenance only requires regular checks of the lubrication and braking systems, extending the maintenance cycle by 50% compared to traditional equipment.
7. Equipped with overload protection, limit position limiters (высота подъема, operating range), emergency stop, anti-sway device (some models), и т. д., compliant with CE, ISO, and other safety certification standards, reducing operational risks.

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 (тонны), span (i.e., track spacing, метры), and lifting height (метры), 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, долговечность, 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.
