Description

Technical Field

[0001] The present invention relates to a shuttle trolley, in particular to a heavy-load low-station lifting shuttle trolley system. Background Art

[0002] Shuttle carts are a commonly used equipment in automated warehousing. They are mainly used at the docking positions of multiple production stations on both sides. Compared with conveyor lines, they have the characteristics of low cost and low energy consumption. Heavy-loaded shuttle carts generally have a relatively large overall structure. After the lifting function is added, the overall structure will be further increased. The hydraulic lifting platform at the bottom of the shuttle cart causes the shuttle cart to increase its transportation and docking height, and the corresponding transportation height of the docking stations on both sides must also be increased accordingly. As a result, it is very inconvenient to manually operate the docking stations on both sides. In order to meet the height requirements of the manual operation stations on both sides and realize the docking of layered distribution at the docking positions, it is necessary to develop a low-station heavy-load lifting shuttle cart system.

[0003] Since the shuttle car's task is to deliver heavy-loaded goods to the conveyor lines on each floor, the shuttle car needs to be equipped with a lifting platform, and a conveyor is set on the lifting platform.
