Semi-Trailer Flatbed Transporter

Semi-trailer flatbed transporters, also known as semi-trailer construction machinery transport vehicles, typically use a concave beam (or well-type) frame. The front section of the frame is a gooseneck (where the traction pin of the gooseneck connects to the traction saddle on the towing vehicle, and the rear end of the gooseneck connects to the semi-trailer frame). The middle section serves as the cargo platform (the lowest part of the frame), and the rear end is the wheel frame (including the wheels).

When loading mechanical equipment onto the semi-trailer construction machinery transport vehicle, it is usually loaded from the rear end of the semi-trailer. This is done by moving the mechanical equipment onto the rear wheel frame or removing the wheels and then securing the equipment onto the semi-trailer.
