Abstract
Industrial trucks commonly include a unitary frame having a roller mast and carriage assembly mounted forwardly thereon. The ability of such trucks to traverse narrow aisles is limited and their stability is normally increased with use of outriggers, counterweights, or the like. The vehicle (10) of this invention, such as an industrial truck, comprises a rear frame (14) and a pair of laterally spaced front frames (16) pivotally mounted forwardly on the rear frame (14). A roller mast (20) and carriage (26) is adapted to be mounted forwardly on the rear frame (14), between the front frames (16). The vehicle (10) will thus exhibit high degrees of maneuverability and stability by its ability to pivot the front frames (16) towards and away from each other, depending on the job task under consideration.
