Bridge crane selection follows a five-step process: "Define Parameters — Determine Level — Determine Type — Determine Environment — Determine Safety and Configuration," ensuring coverage of the work scope, intensity, and safety compliance.

The core of selecting a double girder gantry crane (gantry crane) is: first, determine the application scenario and model → then calculate the three core parameters → match the working level → select the lifting gear and configuration → finally, verify compliance with the manufacturer. The complete selection method is given below step by step.

The selection of a RTG typically requires a comprehensive assessment of factors such as the operational scenario, load requirements, span, work efficiency, and operating environment. Below is a commonly used selection approach applicable to port container yards, steel yards, prefabricated component yards, and warehousing and logistics facilities. ⚙️🚧

**Multi-span lifting beams (also called adjustable lifting beams)** are mainly used for lifting workpieces that are long, have uneven weight distribution, or require multi-point lifting. When selecting a model, key parameters to consider include load capacity, span, adjustable span range, number of lifting points, and lifting method.
