Classification of Trucks

Trucks are motor vehicles that can be used to carry cargo, people or other items. They are typically purchased for commercial operations. Depending on their use, trucks can be classified into several different classes.

Pickup trucks are smaller versions of trucks. Most pickups come in two different wheelbase lengths. The acronym SWB stands for short wheel base.

Medium trucks are larger than light trucks. These trucks are usually designed to be more functional, with a larger capacity for cargo, more passenger capacity and more interior room.

Big trucks are typically about 70 to 80 feet long. They are larger than cars, and weigh 20 to 30 times more. A six-axle truck can have a maximum weight of 44 t (97,000 lb).

Trucks can be used for hauling, towing, or transportation. The vast majority of them have body-on-frame construction. This makes them ideal for off-road operation. In addition, most have a separate cab and bed for carrying cargo.

The steering system of trucks is usually the Ackermann system. It is a belt drive with two forward speeds and one in reverse. It provides a kingpin for each front wheel.

In the past, trucks have been powered by gasoline engines. However, since World War II, diesel engines have become more popular.

Some big rigs have nine or even thirteen gears. Because they are so heavy, they can require a special license. Drivers must be prepared to avoid brake overheating and maintain a safe speed.
