Description

Technical Field

[0001] This utility model relates to the technical field of freight platforms, and in particular to a large-span loading and unloading platform. Background Technology

[0002] A loading and unloading platform is a platform that facilitates loading and unloading of goods from trucks. Ordinary loading and unloading platforms are typically single-story, lower than the warehouse platform, ensuring the warehouse platform is level with the truck bed for easy loading and unloading. Some loading and unloading platforms are multi-story, with ramps connecting each level, allowing smaller trucks or forklifts to access higher levels and participate in loading and unloading, improving efficiency. In multi-story loading and unloading platforms, the beams of the lower level are directly connected to the floor of the upper level. The beams of the lower level directly determine the load-bearing capacity of the floor of the upper level. This significantly limits the construction of the lower level structure, preventing the construction of beams with larger spans. The lower structure has numerous supports to ensure the beams are within a suitable span range. However, these supports can interfere with loading and unloading vehicles, reducing efficiency. A new demand for multi-story loading and unloading platforms with fewer supports and larger spans is emerging. Utility Model Content
