ABSTRACT:
The invention provides apparatus for precise, well controlled positioning and levelling of factory constructed buildings. The apparatus comprises units used in pairs, one near each end of a building being installed. Each unit is a four wheeled vehicle with a jack at each end. Each wheel is independently driven and the units are remotely controlled, using cables, hydraulic or pneumatic hoses or wireless apparatus. In use the units are moved under the building under their own power and adjusted and maneuvered so that the jacks can engage the longitudinal beams used in factory manufactured buildings. The jacks are then operated to raise, lower and level the building and the wheels are driven to move the position the building desired. The jacks support pivotally mounted jack plates which can remain in secure engagement with the beam while the units are maneuvered such that the building can be moved lengthwise or sidewise or turned about an axis essentially perpendicular to the terrain.
