The skeleton semi trailer truck is welded by the longitudinal beam,
cross beam and front and rear end beams. The longitudinal beam is
made of high-quality steel plate 16Mn submerged arc welded into
I-shape (the main dimensions are 450 and 500), the cross beam is
made of high-quality steel plate into a groove, and the front and
rear end beams are welded rectangular sections. An integral long
beam is set at the middle container locking device to improve the
bearing capacity of the container locking device.
Compared with "monobloc" vehicles, semi trailers can improve the
comprehensive economic benefits of highway transportation. The
transportation efficiency can be increased by 30-50%, the cost can
be reduced by 30-40%, and the fuel consumption can be reduced by
20-30%. More importantly, the use of semi trailers can also promote
the organizational form of logistics in China to a certain extent.
