A skeleton semi trailer is a trailer with the axle behind the vehicle's center of gravity (when the vehicle is evenly loaded) and a coupling device that transmits horizontal and vertical forces to the tractor.Semitrailer is generally a three-axle semitrailer, its kind is divided into 11 meters bin column semi trailer, 13 meters bin column, low flat plate semi trailer, skeleton semi trailer and many other kinds.It is a kind of heavy transportation vehicle connected with the semi-trailer head by the traction pin.
Skeleton semi trailer's frame type vehicle is welded by the longitudinal beam, the beam and the front and rear end beam. The longitudinal beam is welded by the high quality steel plate 16Mn submerged arc welding into an i-shape. The beam is stamped into a groove by the high quality steel plate.The middle container locking device is provided with a long integral beam to improve the carrying capacity of the container locking device.
Compared with "mono-type" truck, the skeleton semi-trailer can improve the comprehensive economic benefits of road transportation.Transport efficiency can be increased by 30-50%, cost reduced by 30-40% and fuel consumption reduced by 20-30%.More importantly, the use of semi-trailers can also promote the organization of logistics in China to a certain extent.
