<p>A lift and carry truck, such as a forklift truck, is designed to prevent tip over when lifting a heavy load outside the truck's weheel base. Once lifted the load is shifted to a point near the truck's center of gravity for transport. The truck has a body (10 or 310) and a plurality of ground engaging transport wheels (12, 314 or 318) which define a polygon of normal stability. A lift and carry device (14 or 300) is movably mounted on the body (10 or 310) being driven by drive (16 or 316) back and forth between a lift position in which the center of gravity of the combined load and truck is or may be outside the polygon and a carry position in which the center of gravity of the combined load and truck is within the polygon of normal stability. At least one outrigger stabilizer (18 or 36) mounted on the body (10 or 310) is moved by drive mechanism (34, 104, 108 or 308) back and forth between a stabilizing position in which it engages the ground outside the polygon of normal stability and a transport position in which the stabilizer (18 or 306) is retracted and does not interfere with movement of the lift and carry truck. The lift and carry truck is collapsible for storage under a cargo truck (200) for transportation to a work site.</p> |
