ABSTRACT:
A vehicle and method for raising elongated objects, especially for raising pipes and the like to a ceiling structure in the construction of a building. The vehicle has a pair of transversely extending support stands and a lift such as a scissors lift adjacent each. On top of each lift is a saddle for supporting an object to be raised and a transversely extendable rod with a hook end. A platform may be removably attached to each lift. In the method of operation of the invention to lift an elongated pipe, the rod and the lifts are utilized to engage a pipe in a stockpile and lift the same onto the support stands. Thereafter the lifts are lowered, the elongated pipe is rolled to be over the saddles of the lifts, and the lifts are raised to raise the pipe up to its desired position in the ceiling structure. Other applications of the vehicle and method include raising a very large work platform up to the ceiling structure to be secured thereat, raising a platform having work pieces prearranged thereon in a predetermined order, and supporting a scaffolding for working on the side of a building or the like.
