This box freight train carriage of the present utility model, with polyurethane particularly the casting type polyurethane elastomer material be used to make railway carriage, make full use of the characteristic that its proportion is little, intensity is good, this railway carriage that obtains of way of migrating has following advantage:
(1) casting type polyurethane elastomer has good peel strength and strain property, be applied to lorry body, it is more much smaller than important and because polyurethane is compared with metal, so being the deadweight of the railway carriage of railway carriage material, this polyurethane can effectively alleviate, thereby this part weight can be used to increase charging burden, not changing raising goods transport ability under the lorry gross tonnage situation, therefore can improve conveying efficiency, reduce traffic cost, also help environmental protection.
(2) casting type polyurethane elastomer is owing to have the good and elasticity preferably of resistance to abrasion, avoid or reduce owing to scratch or railway carriage that collision causes damages, or goods and railway carriage collides the infringement to goods, improved safety performance.
(3) the polyurethane coefficient of heat transmission is low, has heat-blocking action, for being used for the easily box-body truck of the goods of pyrometamorphism such as fruit transportation, seafood, meat, egg, helps product and guarantees the quality.
(4) compare with the iron and steel compartment, do not have oxide etch, problem of rustiness.
(5) since railway carriage weight lighten, therefore when empty wagons from heavy and light, fuel oil consumption is low; And big owing to the loading amount when lade, the required fuel oil consumption of unit goods transport reduces equally, and is not only energy-conservation, also reduced greenhouse gas emission, helps environmental protection.
This lorry body can be a road transport with railway carriage, farm vehicle railway carriage, also can be used for the railroad boxcar railway carriage, or the railway carriage used of special purpose vehicle loading thing.
