Flower trellis gantry crane

A truss-type gantry crane is a large lifting equipment characterized by its truss-structured portal frame. It gets its name from the grid-like, open truss structure of the portal beam (resembling a "flower frame" shape). It is widely used in ports, container yards, logistics centers, shipyards, and large warehouses, primarily for cargo loading/unloading, transportation, stacking, and equipment hoisting operations.
