Summary:Suspension device for the bowl of a scraper having draft arms vertically swingably supported by a draft tube attached to a goose neck horizontally swingably mounted on the scraper, the bowl being swingably supported at the free ends of the draft arms. One end of each of a pair of lift cylinder assemblies is arranged at the left and the right side with respect to the center of the scraper body and connected through spherical bushes to the upper rear portion of the goose neck at positions relatively close to each other while the other ends of the lift cylinder assemblies are connected through spherical bushes to a cross member laterally spanning the bowl at positions adjacent to opposite ends of the cross member so that the lift cylinder assemblies extend obliquely permitting the length thereof to be increased so as to improve the stability in the operation of the bowl while the strength of the suspension device is improved.
