The unique feature of the van - type side - curtain semi - trailer lies in the balance between its structure and function. Based on a rigid frame, it uses high - strength curtain fabric on the side that can be opened and closed as a whole. This design not only retains a certain degree of waterproof and dust proof capabilities, but also enables efficient loading and unloading through fully opening the side. Moreover, its self - weight is lighter than that of the fully rigid ordinary van - type semi - trailer, resulting in better cost effectiveness.
Other semi - trailers have their own characteristics. The ordinary van - type vehicle has a fully - enclosed rigid structure, with strong sealing but limited loading and unloading. The fence - type and stake - type vehicles lack effective enclosure, are suitable for heavy loads but are easily affected by the weather. The tank - type vehicle has a dedicated sealed tank body and only serves for transporting fluid or powder goods.
This difference also determines the division of application scenarios. The van - type side - curtain semi - trailer is more suitable for medium - and light - weight goods that need to be loaded and unloaded frequently, such as e - commerce packages and home appliances. It takes advantage of its side - loading and unloading efficiency, lightweight, and moderate sealing. Other vehicle types have their own specialties. The ordinary van - type vehicle protects precision or valuable items that need to be fully enclosed. The fence - type and stake - type vehicles carry heavy - duty goods that are not afraid of rain, such as building materials and agricultural and sideline products. The tank - type vehicle focuses on transporting fluid or powder - type goods, playing an irreplaceable role in their respective fields.
