Choosing a refrigerated truck in Chongqing requires consideration of various factors such as type, purpose, loading weight, exterior color, engine model, number of doors, and number of tires. For example, there are specialized trucks, multi-purpose trucks, specialized work vehicles, off-road trucks, and fully trailer trucks

Uses include box trucks, flatbed trucks, etc; The loading weight includes medium (6 tons<total mass ≤ 14 tons), light (1.8 tons<total mass ≤ 6 tons), heavy (total mass>14 tons, heavy (total mass>14 tons) (T), micro (total mass ≤ 1.8 tons), etc.

A refrigerated truck is a closed box type transport vehicle used to transport frozen or fresh goods. It is a specialized transport vehicle equipped with refrigeration units and polyurethane insulation compartments, commonly used for transporting frozen foods (refrigerated trucks), dairy products, and other items.

When loading, the refrigerated truck should be pre cooled or preheated first. Because the vehicle is parked in an open-air parking lot, the temperature inside the car is usually the temperature of the external environment.

If the temperature of the transported goods is not the ambient temperature, and the goods are loaded into the carriage, the ambient temperature will affect the temperature of the transported goods, resulting in a change in the quality of the transported goods.

So before loading, the carriage needs to be pre cooled to the required temperature. However, the refrigeration unit should be turned off during loading (just like unloading). Many people do not turn off the refrigeration unit when loading and unloading goods, which is a very wrong operation.
