Description

Technical Field

[0001] The present invention relates to the field of transportation, and more particularly, to an anti-tipping device for a transportation vehicle for loading goods. Background Art

[0002] During the use of a transportation vehicle, when the force balance is lost, the vehicle is prone to tipping over during turning. When a transportation vehicle has a tipping failure, it will cause damage to the transportation vehicle itself at least, and in severe cases, it will not only damage the transportation vehicle itself, but also cause damage to other vehicles, building facilities and personnel. Therefore, in order to prevent the transportation vehicle from tipping over, an anti-tipping device needs to be provided on the transportation vehicle. The existing anti-tipping device consists of multiple components, with a complex structure, which increases the difficulty of assembly and requires manual operation by staff for anti-tipping, making the operation inconvenient. Summary of the Invention
