ABSTRACT:
A machine for use in placing of a wall or ceiling panel in position which holds the panel firmly in place as it is nailed into the structure of a building. The machine is mounted on wheeled base and fitted with a support platform mounted by compression springs to fixed arms. The fixed arms are oriented perpendicular to the plane of the support platform, and are pivotably mounted to an extendable arm linkage joined to the base. The extendable arm linkage consists of a plurality of pivotable arms, rotatably linked by a first set of chain drives driven by a first gear motor for rotation of the arms of the linkage to extend or withdraw the platform in relation to the base, and a second set of chain drives driven by a second gear motor which serves to rotate the plane of the support platform with respect to the base plane.
