ABSTRACT:
An apparatus for moving a wall form assembly on a floor includes an upright tubular seat which has upper and lower portions and which confines an axial hole through the upper and lower portions. The upper portion has an internally threaded top section. The lower portion is provided with a radial support projection. A horizontal beam has a front end and a rear end mounted on the upper portion of the tubular seat. A hook member is mounted on the front end of the horizontal beam. A rotary shaft is disposed rotatably in the axial hole and has an upper end and a lower end that extends out of the tubular seat and that has a roller mounted thereon. An operating member includes a threaded shank which has a lower section that extends threadedly into the axial hole via the internally threaded top section of the tubular seat and that is coupled to the upper end of the shaft. The tubular seat is movable upward or downward relative to the shaft upon rotation of the threaded shank so as to permit raising or lowering of the wall form assembly relative to the floor to facilitate adjustment of a position of the wall form assembly on the floor.
