Material carrying vehicle

摘要

A material carrying vehicle and an unloading apparatus therefor adapted to carry and unload bulk material, such as dirt, sand, gravel, rock, construction material, debris, and the like wherein the material carrying vehicle includes an elongated mobile body formed as a generally channel shaped simple rugged dump style structure easily varied to be interchangeable with different prime movers. The body structure has laterally spaced wear or guide members mounted on a bottom wall of the body and each positioned adjacent a respective side wall of the body to be engaged by a lower edge of an ejection blade positioned transverse of the body and movable between a forward end and a rear end of the body by laterally spaced extensible members. The ejection blade has walls extending rearwardly therefrom defining spaced extensions each receiving a portion of a respective extensible member therein and having elongated bearing plates engaging the wear or guide members of the body. The extensible members are hydraulically actuated with free floating mounting and the hydraulic system is balanced to extend and retract the extensible members without binding or excessive side loading. The tailgate automatically opens by material moved by the ejection blade in its rearward movement.
