The length of a semi-trailer is typically around 13 meters, and its total length should not exceed 13.75 meters. Common semi-trailer widths include 2.5 meters, 2.55 meters, 2.8 meters, and 3 meters, while 13 meters is the most common length. In daily life, this type of semi-trailer is mainly used to transport various goods.
According to the "Technical Specifications for Low-Flatbed Semi-Trailers," dump semi-trailers are vehicles used to transport bulk materials such as coal, ore, and building materials. These vehicles are mainly divided into two categories:
One category is heavy-duty and super-heavy-duty dump trucks. These vehicles are mainly used for off-highway transportation, undertaking transportation tasks in large mines and engineering projects. They are usually used in conjunction with excavators to complete the transportation of various heavy materials.
The other category is small and medium-sized ordinary dump trucks, suitable for road transportation, mainly used for transporting loose materials such as sand, gravel, soil, and coal. These vehicles are usually used in conjunction with loaders to meet transportation needs in different scenarios. The length and width of a semi-trailer vary depending on the type of task and requirements.
