A multi-purpose utility vehicle which includes a self-propelled mobile, articulated vehicle having a cab on the chassis providing an enclosed and protected areas for an operator with a telescoping boom assembly pivotally mounted on the chassis for continuous movement through an arc of 360.degree.. The vehicle mounts a lift platform mechanism disposed forwardly of the telescopic boom assembly. The vehicle includes a telescoping, generally pantograph outrigger assembly to provide a lateral support to the rear and/or front end of the vehicle. In addition, the present invention contemplates a novel steering system which comprises multi-steering functions including automatic front wheel steering only; automatic rear wheel steering only, automatic front and rear wheel steering; and front and rear wheel steering for turning through 90.degree. in the same direction.
A Multi-Purpose Utility Vehicle comprising a vehicle chasis mounted for movement on a plurality of wheels, said chasis mounting adjacent the rearward end a telescopic boom assembly disposed for continuous rotation movement about a vertical axis through 360.degree. a hydraulically actuated lift platform assembly disposed forwardly of such chasis, a pantograph-type outrigger assembly mounted at the rearward and forward ends of said chasis for supporting the vehicle during usage thereof said outrigger assembly including a rearward outrigger mechanism and a forward outrigger mechanism, said forward mechanism including a transverse outer tube section fixedly attached to said chasis, a pair of transversely extending inner tube sections disposed for telescopic sliding movement within said outer tube section, hydraulic motor means for transversely extending and contracting said inner tube sections in relation to said outer tube section, hydraulic jack means operably connected adjacent the outer ends of said inner tube sections adapted for vertical movement for raising and lowering said vehicle chasis, said rear outrigger mechanism including a pair of oppositely disposed longitudinally extending outer tube sections fixedly mounted on said vehicle chasis with telescopic intersections disposed interiorally of said outer sections for telescopic extension and contraction in a longitudinal direction, a transverse outer section fixedly connected to the outer ends of said longitudinal sections, transverse intersections mounted for telescopic movement within said transverse outer section, and hydraulic jack means being operably connected to the outer ends of said transverse intersections for vertical movement for raising and lowering said vehicle chasis.
A Multi-Purpose Utility Vehicle comprises a vehicle chasis mounted for movement on a plurality of wheels, said chasis mounting adjacent one end a telescopic boom assembly adapted for continuous rotational movement about a vertical axis through 360.degree., a pantograph-type outrigger assembly mounted at the rearward and forward ends of said chasis for supporting and stabilizing said vehicle during usage thereof, said forward outrigger assembly including a first outer transverse polygonal tube mounted on said chasis and extending in a width-wise direction, a first pair of inner polygonal tubes disposed for independent telescopic movement within said outer transverse tube and transversely in respect to the longitudinal central axis of said vehicle, hydraulic jack means operably connected adjacent the outer ends of said inner tubes adapted for vertical movement for raising and lowering said chasis said rear outrigger assembly including a pair of laterally spaced, parallel polygonal tubes mounted on said chasis and extending in a length-wise direction relative to said chasis, an inner polygonal tube mounted for telescopic inward and outward movement within each of said outer tubes, hydraulic cylinder means for actuating said inner tubes, said inner tubes each having an integral downwardly extending arm section, said arm sections mounting a second transverse outer polygonal tube extending in a width-wise direction relative to said chasis, a second pair of inner polygonal tubes disposed for telescopic independent width-wise transverse movement within said second transverse outer tube, hydraulic cylinder means for actuating said second inner tubes, and hydraulic jack means operably connected the outer ends of said second inner tubes adapted for vertical movement for raising and lowering said vehicle chasis.
