摘要： 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.

摘要： A dock lift has a platform connected at each side to a frame by a scissors apparatus. At one end, a pair of crossed hydraulic cylinders connect the platform and the frame. The hydraulic connections to the cylinders are made so that a load imposed on one side of the platform imposes a load on one cylinder which cylinder in turn causes fluid pressure to be applied to the other cylinder in the sense such that the other side of the platform is drawn downwardly to aid in maintaining the platform approximately level.

摘要： A load-bearing plate is mounted by a plurality of pivotal links above a base plate, and solely for vertical movement toward and away from the base plate. An intermediate frame including two, spaced, parallel side bars is supported by the links between the two plates for swinging movement on the base plate about a pair of spaced, parallel axes. Driving means, such as a hydraulic screw jack is mounted between the two side bars for swinging movement therewith, and has a reciprocable piston rod attached to one of two, parallel shafts mounted at opposite ends in slots in the side bars to reciprocate longitudinally of the bars during the raising and lowering of the load-bearing plate. The reciprocable movement of the two shafts oscillates the links which in turn cause the load-bearing plate to reciprocate only vertically relative to the base plate.
