Single flatbed trailers can be assembled vertically and horizontally to form a variety of variants to accommodate the shipment of large cargoes of different weights and dimensions. There are usually three variants:
① Combined flatbed trailer. It is composed of one or several single flatbed trailers spliced according to the required length.
② Long cargo trailer. The two flatbed trailers are separated by an appropriate distance according to the requirements of the long cargo supporting position, each with a rotatable carrier, and the supporting positions at both ends of the long cargo are fixed on the front and rear two flatbed trailers. The parts form a whole with the vehicle.
③ Bridge trailer. Two flatbed trailers are separated by a certain distance in front and rear, and a hydraulic lifting platform is installed in each, and a bearing bridge is installed between the two lifting platforms, so that the front and rear trailers, the lifting platform and the bearing bridge are connected into one. The load-carrying bridge is the loading point. Overhead trailers are used to transport large shipments with a heavy weight. In addition, based on a single flatbed trailer, other variants can also be formed, such as a clamp trailer, a concave low-flat bed trailer, a gooseneck semi-trailer, etc., to suit different usage requirements.
