What kind of car is it called to move big items?

A truck is a commercial vehicle designed and equipped mainly for carrying goods, whether it can tow a trailer or not. Trucks are generally called trucks, also known as trucks, which refer to cars that are mainly used to transport goods, and sometimes refer to cars that can tow other vehicles, belonging to the category of commercial vehicles. Generally, according to the weight of the car, it can be divided into heavy and light. Most trucks use diesel engines as power sources, but some light trucks use gasoline, liquefied petroleum gas or natural gas.

Truck, officially named truck, is a kind of automobile used to carry goods and commodities, including dump trucks, tractors, off-road and off-road trucks and various vehicles specially manufactured for special needs. See English-Chinese truck dictionary and truck atlas.

The truck consists of four parts: engine, chassis, body and electrical system. The movement of the freight car is mainly completed by the engine and chassis, in which the chassis includes transmission system, running system, steering system and braking system.

That is to say, after the general truck or semi-trailer is attached, a plate frame, trailer frame or semi-trailer frame is added. Because the turning radius of additional vehicles increases, the dead angle after driving also increases, so some areas will include them as special vehicles [such as the world-famous Australian road train].
