Comprehensive Insights
Lifting Capacity
The lifting capacity of a gantry crane is a critical specification. It determines the maximum weight the crane can safely lift. For instance, the Yuantai gantry crane can handle loads up to 550 tons, making it suitable for heavy industrial applications. In contrast, smaller models may only lift up to 0.5 tons, ideal for light-duty tasks.
Lifting Height
Lifting height is another vital specification. It refers to the distance from the ground to the highest point the crane can lift a load. This feature is crucial in environments with height restrictions, such as warehouses or manufacturing plants. Gantry cranes can be customized to meet specific height requirements, ensuring versatility in various applications.
Span
The span of a gantry crane is the distance between its legs. This measurement is essential for determining the crane’s operational area. A wider span allows for greater maneuverability and the ability to lift larger loads. Depending on the design, spans can range from 2 to 35 meters, accommodating different workspace dimensions.
Control Type
Control options for gantry cranes vary, providing flexibility in operation. Remote control systems allow operators to manage the crane from a distance, enhancing safety and efficiency. Cabin control offers a more traditional approach, while panel control provides a straightforward interface for operators.
Power Supply
Most gantry cranes operate on a three-phase power supply, typically 380V and 50Hz. This power configuration ensures efficient operation and is compatible with most industrial settings. Custom power supply options may also be available to meet specific operational needs.
Working Duty
Gantry cranes are classified based on their working duty, which indicates how frequently they can be used and the load they can handle. The classifications range from light duty (A1-A3) for infrequent use to extra heavy duty (A8-A9) for continuous operation under heavy loads. This classification helps businesses select the right crane for their operational demands.
Wheel Load
The wheel load specification is crucial for ensuring the crane’s stability and safety. It refers to the maximum vertical pressure exerted on the wheels when the crane is fully loaded. Understanding this specification helps in designing the crane’s support structure and selecting appropriate wheels for the application.
Conclusion
Gantry cranes are versatile and essential tools in various industries, offering a range of specifications and types to meet diverse lifting needs. Understanding the technical features and classifications of gantry cranes can help businesses make informed decisions when selecting the right crane for their operations. Whether you are looking for a lightweight single girder crane or a robust double girder model, there are options available to suit your specific requirements.
