A dump trailer is a type of trailer equipped with a self dumping device, usually consisting of a tractor and a tow truck. The self dumping device allows the trailer carriage to tilt and lift, automatically unloading materials without the need for manual unloading, greatly improving unloading efficiency. This type of trailer is widely used in various situations that require frequent loading and unloading of goods, such as construction sites, mines, agriculture, and other fields.

ATV trailer is a type of trailer specifically designed for towing ATVs (all terrain vehicles).

ATV trailers may have multiple functions, such as easy loading and unloading of ATVs, providing protection, and safe transportation. Meanwhile, depending on different uses and scenarios, ATV trailers may also have different designs and configurations. For example, some ATV trailers may have special suspension systems to adapt to uneven road surfaces, while others may have storage space for carrying other equipment or supplies.

Travel trailers provide travelers with additional living space, including bedrooms, kitchens, living rooms, etc., making long-distance travel or camping more comfortable. Compared to purchasing a large RV, the price of a travel trailer is usually more affordable. Meanwhile, trailers can be stored in dedicated parking lots when not in use, reducing daily maintenance and insurance costs.

A semi-trailer is a type of truck that consists of a tractor and a trailer. A tractor is a commercial vehicle equipped with a special device for towing a trailer, which is partially placed on the tractor. This structure deprives the semi-trailer of its own driving force and requires the use of traction pins to connect to the towing vehicle, relying on the driving force of the main vehicle to achieve driving. Semi trailer trucks are commonly used for transporting bulk goods such as sand, stones, steel, etc., because they have a large cargo carrying capacity and flexible transportation methods.
