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.
