Flat-Bed Truck
This is a type of truck which can be either articulated or rigid. As the name suggests, its bodywork is just an entirely flat, level ‘bed’ with no sides or roof. This allows for quick and easy loading of goods, and consequently they are used to transport heavy loads that are not delicate or vulnerable to rain, and also for abnormal loads that require more space than is available on a closed body.
Dry-Van
A large proportion of a semi-trailer weight is supported by a tractor unit, or a detachable front-axle assembly known as a dolly, or the tail of another trailer. The other portion of the semi-trailer weight is semi-supported by its own wheels, which only support the rear of the semi-trailer. A semi-trailer is normally equipped with landing gear – legs which can be lowered to support it when it is uncoupled. Many semi-trailers have wheels that are capable of being totally dismounted and are also relocatable to better distribute load to bearing wheel weight factors. Semi-trailers are more popular for transport than full trailers, which have both front and rear axles.
Step-Deck Trailer
A step deck trailer, also known as a drop deck or lowboy trailer, is a commercial trailer designed to carry tall cargo that exceeds the legal height limit if transported on a traditional flatbed trailer. Transporting tall cargo on a step deck prevents drivers and operators from having to obtain permits.
Reefer
A refrigerator truck or chiller lorry is a van or truck designed to carry perishable freight at low temperatures. Most long-distance refrigerated transport by truck is done in articulated trucks pulling refrigerated semi-trailers.
Tanker
A tank truck, gas truck, fuel truck, or tanker truck, is a motor vehicle designed to carry liquids or gases on roads. The largest such vehicles are similar to railroad tank cars which are also designed to carry liquid loads. Many variants exist due to the wide variety of liquids that can be transported. Tank trucks tend to be large; they may be insulated or non-insulated; pressurized or non-pressurized; and designed for single or multiple loads often by means of internal divisions in their tank. Some are semi-trailer trucks. They are difficult to drive and highly susceptible to rollover due to their high center of gravity, and potentially the free surface effect of liquids sloshing in a partially filled tank
