Product Description


The gantry structure forms the crane's framework, providing strength and stability for heavy lifting. Key components include:
Main Girders (Beams): These horizontal beams span the crane's width, supporting the hoist and load. The double girder design enhances load-bearing capacity and stability, typically constructed from high-strength steel.
Legs (Columns): The legs support the girders and connect the crane to the ground or rails. For rail-mounted cranes, the legs feature wheels that move along tracks, while in some configurations, they may include adjustable heights for specific lifting needs.
1. it can reduce manpower, realize hoisting machinery, reduce production and operation costs, and improve work efficiency.
2. simple structure, easy installation, good usability and efficient high performance.
3. low maintenance cost, standardized, generalized and serialized parts.
