Apparatus for transporting/mounting a building material

An apparatus for transporting/mounting the building material comprising:

• a self-propelled vehicle body provided with a steering/driving means, said vehicle body assuming a substantially L-shaped form constructed of an upright main body and a pair of lower frames which are parallelly spaced apart from each other and horizontally extend from opposite sides of a lower portion of said upright main body of said vehicle body;
• an elevator unit movably mounted on a vertical side portion of said upright main body of said vehicle body so as to be vertically movable along said vertical side portion of said upright main body of said vehicle body;
• a first frame means horizontally extending from a vertical side portion of said elevator unit, said first frame means having a base-end portion mounted on said elevator unit so as to be horizontally movable in a horizontal plane relative to said elevator unit;
• a second frame means slidably mounted in said first frame means so as to be extended therefrom and retracted therein in a longitudinal direction of said first frame means;
• and
• a supporting means for supporting said building material, said supporting means being so mounted on a front-end portion of said second frame means as to be vertically swingable and as to be rotatable on an axis perpendicular to a plane in which said building material having been supported by said supporting means lies;
• wherein
• said supporting means comprises:
• an adapter plate fixedly mounted on a front-end portion of a vertical mounting plate which is mounted on a front-end portion of said second frame means through a pivot so as to be swingable in a vertical plane;
• a guide ring fixedly mounted on an outer peripheral surface of a side portion of said adapter plate;
• a swivel plate provided with a ring-like projection in its rear surface, said ring-like projection being rotatably mounted on an inner peripheral surface of said guide ring through a plurality of balls so as to be adjacent to a front surface of said adapter plate, said swivel plate being connected with a swivel motor fixedly mounted on said adapter plate;
• a supporting plate mounted on said swivel plate through bracket means and a pivot so as to be swingable in a horizontal plane relative to said swivel plate, said bracket means being fixed to a substantially central portion of a front surface of said swivel plate, said pivot being mounted on said bracket means, said supporting plate being provided with a plurality of through-holes for supporting said building materials;
• and
• a control means for swingably driving said supporting plate in a plane perpendicular to said swivel plate so as to position said supporting plate relative to the surface of a building body.
