Description

Technical Field

[0001] The utility model relates to the technical field of transport vehicles, in particular to a heavy-load AGV omnidirectional vehicle. Background Art

[0002] AGV, or Automated Guided Vehicle, is an unmanned transport tool widely used in industrial production, logistics, warehousing and other fields. Equipped with automatic navigation devices such as electromagnetic or optical devices, AGV can drive autonomously on a preset path to complete material handling tasks. This type of vehicle not only improves production efficiency and reduces labor costs, but also enhances the safety of the working environment.

[0003] However, traditional AGV carts often collide when in use because they are unmanned and automatically guided. In addition, conventional AGV carts have small available space and weak loading capacity, which can easily affect transportation efficiency to a certain extent when in use. Utility Model Content
