FRAME STRUCTURE FOR TRACK-TYPE VEHICLE Abstract of the Disclosure A modular construction for a crawler assembly in track-type vehicles and a structural arrangement of the craw- ler assembly with the vehicle frame are described. In each crawler assembly there is a central side frame member which is integral with the vehicle frame and extends laterally from it for carrying the crawler track in the intermediate portion of its travel. Each central side frame member is equipped with upwardly-extending track support rollers carrying the crawler track while downwardly-extending track rollers are provided for guiding the crawler track and supporting the vehicle on the surface on which it is traveling. The idler roller is carried by a first modular member which is bolted to a first end of the side frame member. A second modular member carrying the crawler sprocket is bolted to the other end of the central side frame member. In order to provide track rollers immediately adjacent the idler roller and the crawler sprocket bogies are pivotally mounted, respectively, at each end of the central side frame member, and these bogies carry, respectively, a pair of track rollers. The bogies are arranged to extend, respectively, to points adjacent the idler roller and the crawler sprocket.
