A truck or rorry is a large motor vehicle typically designed to transport heavy loads, carry special payloads, or do other utilitarian work. Trucks range widely in size, horsepower, and configuration, though most trucks feature a body-on-body construction, which means that the entire vehicle is made up of a reinforced frame, chassis, and engine/transmission unit. The cab of a truck is designed for passengers as well as cargo; therefore, it has a wide range of features to make carrying cargo and passengers easier. The design of a truck or rorry varies greatly.
One type of truck is the passenger car, sometimes called a van. These are used for transporting people as passengers. However, many passenger cars are also modified for transporting goods, making them very versatile both in purpose and application. Many passenger cars have a larger than usual bed to provide accommodation for a large freight load. Also, some trucks have large sleeping areas in the bed itself, allowing passengers to stay in the comfort of the truck while it is being transported. They often have facilities for stowing stoves or refrigerators.
Another type of truck is the multipurpose passenger vehicle, orPMV. These are generally used for commercial purposes like carrying goods or passengers. Some of these trucks are dual-purpose: they can be used for hauling freight and passengers at the same time. The cab of a PMV is designed for long journeys, providing adequate room for both hauling capacity and passengers. Many of these vehicles are constructed with climate control as a standard feature.
The third major truck classification is the heavy-duty truck. These are more massive than passenger cars, though not as heavy as tractor trucks. Heavy-duty trucks are used mainly for transporting heavier items. They have enough power and mass to haul anything that needs to be moved. The engine of a heavy-duty truck is typically double the size of that of a regular car, enabling it to transport heavier loads. Heavy-duty trucks are also equipped with certain features to facilitate moving and parking.
Pickup trucks are smaller than other passenger cars. As a result, they have fewer functions and parts. However, this small size makes pickup trucks ideal for transporting small loads. These trucks are normally classified according to the function of their pickup.
Finally, there are utility trucks. These trucks are used for carrying objects and materials that need to be carried away. In most cases, utility trucks have a bed fit for carrying goods, which makes them ideal for transporting construction materials. Most utility trucks also have storage compartments, allowing drivers to transport supplies in a closed space. Finally, utility trucks are classed according to the amount of cargo they can carry at one time.
