Description

Technical Field

[0001] The present invention belongs to the technical field of transportation equipment design, especially the technical field of transportation container design, and particularly relates to a riveted aluminum alloy open-top container. Background Art

[0002] Existing conventional containers are usually made of steel, such as the existing 20-foot 35-ton open-top container which is designed and manufactured using steel. Due to the high density of steel, the self-weight of a 20-foot 35-ton open-top container is generally about 2.7t. The transportation weight of railway freight cars is generally 70t. If a railway freight car transports two steel 20-foot 35-ton open-top containers, the load capacity of each open-top container is only 32.3 tons. To improve the load capacity of the open-top container, it is necessary to reduce the self-weight of the open-top container and enhance the efficiency of logistics transportation. Therefore, it is necessary to design an open-top container made of aluminum alloy, which has a lighter self-weight and a higher load capacity. Summary of the Invention
