Trailer

Definition

A trailer, in the context of freight and logistics, is a non-motorized, towable vehicle designed for carrying various types of goods. These units are typically connected to a motorized vehicle, like a truck or tractor, that provides the power to move the trailer from one location to another. Trailers are an integral part of the transportation and logistics industry, facilitating the movement of all sorts of cargo over long distances. They come in a variety of types to cater to specific types of goods or requirements, such as flatbed trailers, refrigerated trailers (also known as reefers), box trailers, tanker trailers, among others.

FAQ

Several types of trailers are utilized in the logistics sector, including: - Flatbed Trailer: Suitable for heavy and large loads that may not fit in a closed trailer. - Refrigerated Trailer (Reefer): Specially designed to transport temperature-sensitive items, such as food and pharmaceuticals. - Box Trailer: Ideal for general cargo that needs protection from weather and other external factors. - Tanker Trailer: Used for hauling liquid or gas commodities. - Low Loader: Primarily used for moving heavy machinery or vehicles as they have a lower deck, making loading easier.
Trailers are attached to motorized vehicles using a device known as a hitch. Various coupling mechanisms exist, but in commercial freight logistics, the most widely used is the fifth-wheel coupling. This coupling mechanism provides a secure connection, ensuring the trailer doesn't detach during transit.
Several factors need to be evaluated when choosing a trailer for freight transport, including: - Nature of Goods: The type of cargo determines the kind of trailer needed. For instance, perishable goods necessitate the use of a refrigerated trailer. - Cargo Weight: The cargo's weight must not exceed the trailer's load capacity. - Loading/Unloading Infrastructure: The facilities at the pickup and delivery points may dictate the type of trailer suitable for the job. - Legal Limitations: Certain jurisdictions have specific regulations regarding the permissible size and weight of trailers.
The carrying capacity of a trailer is typically gauged in terms of volume (measured in cubic meters or cubic feet) and weight (measured in tons or pounds). It signifies the maximum quantity of cargo that the trailer can hold legally and safely.
Example or usage in road freight logistics

Consider a scenario where a logistics service provider is contracted to transport a substantial amount of canned food from a manufacturing facility to a distribution center. Given the nature of the goods — palletized and requiring protection from the elements — the provider opts to use a box trailer. The trailer is hooked to a truck, loaded with the cargo at the manufacturing site, and then driven to the distribution center where the goods are offloaded.
