Abstract
Systems are described involving (i) a plurality of columns disposed around the object to be lifted, each column having a rack extending longitudinally along one side thereof (ii) means for carrying the object (iii) means keeping the columns upright during lifting and supporting operations (iv) means at the base of the columns to keep them from sinking in the terrain (v) a jacking system on each column and connected to (ii) so that the object can be raised in step-by-step fashion by means of a rack and pawl system and (vi) driving means to operate the jacking systems either in unison or individually as desired. Building modules or the like are raised and held in place by the system while a permanent supporting structure is placed, erected or constructed thereunder.
Claims14
A lift and supporting system for building structures or the like which comprises:
- 1. a plurality of columns adapted to be positioned in a suitable load-support plan about the structure to be lifted and supported, each column having a rack extending longitudinally along one side thereof;
- 2. structure carrying means adapted to be placed beneath the structure and to carry the same during the lifting operation;
- 3. guy means extendable downwardly and outwardly from the upper portions of the individual columns and adapted to maintain said columns in an upright position while the structure is supported on said structure carrying means;
- 4. base plate means at the base of each said column for distributing the load over an area sufficiently large to restrain the column against undue sinkage into the supporting terrain thereunder while the structure is supported on said structure carrying means;
- 5. a plurality of elongated members operatively connectable to extend between adjacent columns in the load-support plan thereby to form a frame restraining said columns against undue movement in any lateral direction while the structure is supported on said structure carrying means;
- 6. a jacking system adapted to be operatively mounted on each column, each jacking system including
- a. a pair of individually moveable members encircling the column
- b. pawl means mounted on each said member
- c. double acting hydraulic fluid motor means connected to the pair of individually moveable members for effecting selective relative movement therebetween longitudinally along the column
- said pawl means cooperating with the rack on said column whereby the pawl means of one of said pair of members is in load-supporting engagement with said rack as the other of said pair of members is being moved in a preselected direction longitudinally along the column by said motor means,
- one member of each pair of said individually moveable members being operatively connectable to said structure carrying means to enable lifting and supporting of the structure to be effected;
- and
- 7. control means for selectively actuating each of said motor means so that the structure may be lifted and supported in the desired position.

- 2. means at the base of each said column for distributing the load over an area sufficiently large to restrain the column against undue sinkage into the supporting terrain thereunder while under load;
- 3. a wheeled trailer vehicle carrying said columns, said vehicle including a load supporting surface adapted to carry the structure, said plurality of columns being pivotally mounted on said vehicle in a suitable load-support plan, each such column being positioned to be rotated into upright position around an axis positioned in a vertical plane outside the adjacent outer periphery of said surface so that said means at the base of each said column can be positioned at essentially normal ground level and each said column when in said upright position extends upwardly adjacent the outer periphery of said surface;
- 4. means adapted to maintain said columns in an upright position while the structure is supported above the supporting terrain on said trailer vehicle;
- 5. a jacking system operatively mounted on each column, each jacking system including
- a. a pair of individually moveable members encircling the column
- b. pawl means mounted on each said member
- c. driving means connected to the pair of individually moveable members for effecting selective relative movement therebetween longitudinally along the column,
- said pawl means cooperating with the rack on said column whereby the pawl means of one of said pair of members is in load-supporting engagement with said rack as the other of said pair of members is being moved in a preselected direction longitudinally along the column by said driving means,
- one member of each pair of said individually moveable members being operatively and pivotally connected to said trailer vehicle thereby
- a. furnishing the pivotal mounting and enabling the rotation referred to in sub-paragraph (3) of this claim, and
- b. enabling the lifting and supporting of the trailer vehicle and the structure carried thereon to be effected;
- and
- 6. means for selectively actuating each of said driving means so that the trailer vehicle and the structure carried thereon may be lifted and supported in the desired position.
