Disclosed are systems, method and devices for the processing of plasterboard sheets to provide cut plasterboard panels which are appropriately dimensioned for installation on a building site. The technology provides devices for measuring building framing, translating the building measurements to cut instructions, equipment and processes for cutting the plasterboard sheets, systems and methods of unloading, stacking and transporting the cut plasterboard panels, as well as instructions for installation.

A lift assembly supports a pole at a desired position extending upwardly from a lift to facilitate supporting a panel at a desired position over the lift. The lift is configured to couple to a scaffold. The lift also is configured to selectively slidably couple to a pole. The pole is configured to slide upwardly relative to the lift to raise the pole to a desired position extending upwardly from the lift.

A multi-purpose tool that provides a hammer, a hatchet, a cutting blade, a lift support, a screw puller and a rasp for use in the installation of drywall sheets used in constructing walls within buildings.

Implementations of the present invention relate to apparatuses, systems, and methods for constructing and installing architectural walls that are secured to a floor and/or a ceiling and include one or more leveling mechanisms. The leveling mechanisms may allow the architectural wall to be selectively adjusted vertically relative to the floor and/or ceiling so that a horizontal positioning of the wall may be achieved. The leveling mechanisms may also allow the architectural wall to fit securely to a floor and/or ceiling.

An adjustable support, comprising a base, a first tubular member extending upwardly from the base, the first tubular member comprising a first friction lock, a second tubular member arranged in telescoping engagement with the first tubular member, the second tubular member comprising a second friction lock and, a non-abrasive transverse member pivotably arranged on the second tubular member, wherein the first friction lock telescopingly secures the second tubular member within the first tubular member and the second friction lock pivotably secures the transverse member to the second tubular member.

A panel lifting device includes a rigid beam and a roller coupled to the beam. The panel lifting device is pivotable at a fulcrum. A beam body includes an upper foot platform. The upper foot platform may have a width gradually increasing from the proximal end of the beam body toward the distal end of the beam body. The roller may be coupled to the beam by opposite tabs extending inward from opposite side walls and received in open ends of the roller. The opposite tabs may be integrally formed with the side walls. A rigid wing may extend downward from the upper foot platform adjacent the roller and opposing an outer circumferential surface of the roller. The rigid beam may be a single, one-piece, integrally formed component formed from a single sheet of metal.
