The invention relates to the field of manufacturing and application of light-weight logistics equipment, in particular to a light-weight aluminum
alloy carriage which comprises a bottom plate
assembly, and the bottom plate
assembly comprises a front end part and a rear end part which are arranged front and back on the axis; the front end portion comprises a transversely-laid aluminum
alloy profilebottom plate, and the
extrusion direction of the transversely-laid aluminum
alloy profile bottom plate is perpendicular to the axis of the bottom plate
assembly. The rear end part comprises an aluminum alloy square tube cross beam and a longitudinally-laid aluminum alloy profile bottom plate; and the aluminum alloy square tube cross beam is perpendicular to the axis of the bottom plate assembly.According to the light-weight aluminum alloy
carriage provided by the invention, the process difficulty of production and manufacturing is reduced; compared with the prior art, the
production cycle isshortened, the
carriage combination efficiency is improved, particularly, under the condition that the overall lightweight design effect of the carriage is better and the cargo
carrying capacity is equivalent, the carriage is greatly lightened, the logistics transportation efficiency is greatly improved, the loading capacity, deformation resistance and
impact resistance of the carriage are improved, and safety is guaranteed while the logistics transportation efficiency is improved.
