[0002] With the continuous development of logistics and warehousing technology, the popularity of automated high-bay warehouses is also increasing. Automated high-bay warehouses can increase storage capacity by increasing vertical storage space within the same floor area, and can achieve efficient retrieval and placement of goods through automated systems. The use of automated high-bay warehouses helps shorten logistics time, save logistics costs, and improve logistics efficiency.

[0003] Stackers are core equipment in automated warehouses. They can be operated manually, semi-automatically, or fully automatically, enabling efficient cargo transfer and placement. The fork is the actuator at the end of the stacker, and its operating efficiency and stability directly impact the overall efficiency and stability of the stacker. As the application of stackers continues to expand, higher requirements are being placed on the fork's structural strength and positioning accuracy.

[0004] Existing forks are mostly used in bracket-type racks or elevated beam-type racks. These types of racks have the disadvantages of high cost and low storage density. However, due to the top load, existing forks are difficult to apply to other types of racks. Existing forks have poor repeatability and positioning accuracy, making them difficult to apply to areas with high precision requirements. Improving accuracy will lead to the complication of the fork structure and increase costs.

[0005] In summary, there is a need in this field to improve the existing fork structure to adapt to the needs of high-density and high-precision cargo picking and placing, while improving the structural strength and reducing production costs. Utility Model Content
