[0001] The utility model relates to a cargo box with a folding guardrail, belonging to the technical field of mining equipment. Background Art
[0002] In recent years, mining dump trucks have been developing towards large tonnages, and the cargo boxes used are getting larger and larger, which has brought quite a lot of trouble in the transportation of equipment due to road height limits. During market use, it is generally mainly stacked to transport more materials. However, during heavy-load downhill driving, the stacked materials will slide forward. Especially when loading large pieces of earth and rock or minerals, they will roll over the cargo box brim and fall onto the cab ceiling or the front windshield, causing great potential safety hazards.
