There are three main types of trailers: hook-and-chain trailers, wheel lift trailers and flat trailers. ‌

‌ chainhook trailers ‌ : Also known as sling trailers, work by winding a chain around the axle or frame of a vehicle. This type of trailer is commonly used on vehicles damaged in accidents, vehicles without front or rear wheels, and vehicles with steel bumpers. However, because the use of chains can cause damage to the vehicle, such trailers are not used as often as before.

‌ wheel lift trailer ‌ : Using a metal yoke instead of a chain, it is hung below the wheels of the vehicle being towed and the front or rear of the vehicle is raised from the ground by a hydraulic or pneumatic crane. This trailer is capable of effectively lifting the vehicle and is suitable for a variety of vehicle situations requiring special handling ‌.

‌ flatbed trailer ‌ : Also known as a tilting trailer, a large empty bed in the back of the truck that can be tipped hydraulically to form a ramp shape. The vehicle can be driven onto the slab or dragged into place using a winch. A flatbed trailer is the preferred method of towing a vehicle because it does not stress or drag the vehicle for a period of time, but instead puts all the stress on the trailer ‌.

In addition, there are other categories of trailers according to different standards and uses. For example, according to the driving force of the vehicle, the trailer has a manual two-drive model, an automatic two-drive model, an automatic time-sharing four-drive model and an automatic full-time four-drive model. From the point of view of use and structure, the trailer also includes road wreckers, tractors, dump trailers, etc. These trailer types are diverse and can meet different needs.
