Having absorbed the merits of current trailers in China, LGN*7CH*1Y series reinforced-type hydraulic dumper-trailer is a new product which has been developed by our company through optimizing design. As far as its strength of structure, loading capacity, braking efficiency and durability are concerned, the trailer ranks first among the same products in China, since it has adopted the enlarged axle, renlarged-size drum, loading-size bearings, einforced packing box bed and rear axle made of superior mid-carbon structural stell. It is really the best product for the customers to select.
