What are the types of box trucks?

　　Standard box-type van: Used for transporting general goods, such as electronic products and daily necessities.

　　Refrigerated box trucks: Equipped with a refrigeration system, they are used for the transport of temperature‑controlled goods such as fresh produce and pharmaceuticals, and can be further categorized as follows:

　　Refrigerated truck (-10°C to -18°C)

　　Refrigerated truck (-3°C to -4°C)

　　Hazardous‑material box‑type transport vehicle: Specifically designed for the carriage of chemicals and other hazardous substances, it must comply with applicable safety standards.

　　Wing-open van: The side wings or roof of the cargo compartment can be opened for quick loading and unloading.

　　Box-type LTL truck: Used for transporting small‑batch, multi‑shipper cargo, typically equipped with side doors, a rear door, and ventilation and lighting facilities.

　　Box-type work vehicles—such as mobile vending carts and maintenance trucks—are used for specialized tasks rather than mere transportation.

　　Micro/light‑duty vans: with a gross vehicle mass of ≤ 4.5 tonnes and a body length typically ranging from 3 to 5 metres, they are well suited for last‑mile urban delivery.

　　Medium-sized van: gross vehicle weight 4.5–12 tonnes, used for short- and medium-distance transportation between urban and rural areas.

　　Heavy-duty box trucks: gross vehicle weight exceeding 12 tonnes, suitable for interprovincial trunk-line transportation.
