Types of Semi Trailers

​A refrigerated freight firm in Channahon, Illinois, Select One Inc. assists diverse business types with their transportation needs. By tailoring the trailer type to each shipment, Select One Inc. ensures that loads arrive undamaged and on time.

Semitruck trailers differ depending on dimensions, the vehicle they are attached to, and their capacity and intended freight type. The flatbed trailer is the simplest of all, is usually between 48 to 53 feet long and 8.5 feet wide, and can accommodate up to 48,000 pounds. Warehouse or logistics workers can load cargo on to a flatbed from all sides with either a forklift or crane, and the flatbed lacks a roof, exposing the cargo to the elements. Common variants of the flatbed trailer include the step deck trailer, with the same overall length but decks of gradually decreasing length, and the lowboy, which has only one deck but can carry heavier loads, at the cost of trailer height.

Other semitruck trailer types vary the flatbed formula to suit certain conditions. Dry vans and reefer trailers are completely enclosed, keeping their contents dry, and reefers are also insulated and refrigerated so the contents remain within an ideal temperature range. Tanker trailers carry liquids in bulk, while pneumatic tanks carry bulk granular products like flour and building materials.
