The structural design of the European-style double-girder bridge crane breaks through the traditional "heavy structure, large size" model, achieving lightweight through "material optimization + structural simplification" while ensuring load-bearing stability

1. Main beam and end beam: Thin-walled profiles + modular splicing

The main girder typically adopts a box-shaped thin-walled welded structure (often made of Q355B material), with a web thickness reduced by 15%-30% compared to traditional Chinese cranes. Through finite element analysis, the stress distribution is optimized to reduce self-weight (the overall weight is 20%-40% lighter than traditional models) while ensuring torsional and bending resistance;

The end beam is constructed using standardized profile splicing (such as H-beam or square tube) rather than traditional cast steel components, resulting in lighter weight and higher assembly efficiency. Additionally, the connection between the end beam and the main beam employs high-strength bolts (rather than welding), facilitating transportation, on-site assembly, and future maintenance or modification.

2. Hoisting mechanism: The winch is integrated, replacing traditional winches

The lifting mechanism adopts European-style wire rope hoists (or chain hoists) as the core component, integrating the motor, reducer, brake, drum, and wire rope (or chain) into a compact structure (with a volume 30%-50% smaller than traditional winch lifting mechanisms);

The connection between the葫芦 and the main beam is achieved through a lightweight trolley frame, which is made of aluminum alloy or high-strength steel. The trolley frame features low wheel pressure (reducing the wheel pressure by 20%-30% compared to traditional designs), thereby decreasing the load on the main beam. This also lowers the design load requirements for factory column brackets and tracks, indirectly reducing the construction costs of the factory.
