What is the difference between a light duty crane and a light weight crane?

In the crane industry, “light duty cranes” and “light weight cranes” are not the same and refer to completely different concepts. Light Duty Cranes relate to the operational duty classification of the crane. This classification is based on standards like FEM, ISO 4301, and CMAA, which define crane duty according to lifting frequency, load cycles, and load variation. Light duty cranes are designed for occasional use, low lifting frequency, and lighter operational demands, often in environments where durability and reliability requirements are moderate. For example, a 10-ton crane that is used infrequently could still be classified as light duty. A common scenario is a double girder crane in a maintenance workshop that occasionally lifts a 3-ton component. Light Weight Cranes, on the other hand, refer to the physical weight of the crane itself. These cranes are designed with lightweight materials—such as aluminum alloy rails or hollow structures—to reduce the overall crane weight. The main goal is to reduce load on the building structure and simplify installation or mobility. However, a lightweight crane can be designed for heavy duty applications if it is used frequently, even with relatively small loads. In summary, light duty focuses on the crane’s usage and operational demands, while light weight focuses on the crane’s physical structure and mass. They can overlap but are not interchangeable terms.

What’s the difference between a light duty gantry crane and a light duty overhead (bridge) crane?

While both light duty gantry cranes and light duty overhead cranes are designed for lifting lighter loads in low-duty-cycle environments (typically A1–A3), the main difference lies in their structure and installation. Gantry cranes are freestanding systems supported by legs and usually operate on the ground or rails, making them ideal for open spaces or temporary work areas. In contrast, light duty overhead (bridge) cranes are typically ceiling- or runway-mounted and are better suited for permanent indoor applications where floor space needs to be preserved. If you're deciding between the two, consider your workspace, mobility requirements, and installation conditions.

什么是轻型龙门起重机

轻型龙门起重机是一种专为低强度应用而设计的龙门起重机，此类起重机使用频率不高，起重能力适中，且在极低的应力条件下运行。“轻型”并非指起重机的起重能力，而是指工作条件和使用频率，正如 FEM、ISO 4301 和 CMAA 等国际标准所定义。

这些起重机通常结构紧凑，通常采用单梁或便携式框架，并可能配备手动或电动葫芦。它们具有经济高效、重量轻、易于安装或移动等特点，是临时或灵活办公空间的理想选择。

尽管名称如此，轻型起重机仍然可以吊起重物（例如 5 至 10 吨），但定义它的是其工作等级 - 通常为 ISO 或 FEM 标准下的 A1 至 A3 - 表示长时间内的运行强度较低。

简而言之，轻型龙门起重机最适合于效率、经济性和偶尔使用比连续重型起重或高速运行更重要的应用。
