Abstract
A door transporting and mounting machine is disclosed for transporting an mounting a door relative to a complementary door frame. The machine includes a wheeled supporting frame for portably transporting a door to a selected door frame site. A generally vertically extending column extends upwardly from the supporting frame and includes a carriage mounted on the column for movement between lower and upper positions. Door gripping arms are pivotally mounted on the movable carriage for re-positioning the door between a horizontal transporting position and a vertical mounting position. When the machine is located at a complementary door frame, the movable carriage, with associated door gripping arms, moves the door to properly aligned position for mounting the door relative to its complementary door frame.
Claims21
A door transporting and mounting machine comprising:
- a wheeled supporting frame;
- a generally vertically extending column attached to said frame and extending upwardly therefrom;
- generally horizontally extendable supporting members on opposite sides of said column for underlying and supporting a door in a horizontal transporting position;
- a carriage mounted on said column for movement in a generally vertical path between lower and upper positions;
- door gripping means for gripping and supporting a door, said door gripping means being pivotally mounted to said carriage for re-positioning the door between a horizontal transporting position and a vertical mounting position;
- and
- means for raising and lowering said carriage along said column to assist in mounting the door relative to a door frame.
