An improved scaffold system suitable for tunnel roofing and siding, and other applications above and below the ground is disclosed. This invention is a diesel powered, hydraulically actuated, mobile and adjustable scaffold system that an operator can drive into a work area, such as a tunnel. Once at the work area, the operator can address the work face head on, and can adjust the workpiece carried on the work bearing surface of the system in every possible dimension. This invention compries a self-powered vehicle assembly and a multi-table assembly. The vehicle assembly provides a general level of mobility and maneuverability to the entire system. The multi-table assembly mounted on top of the vehicle assembly includes several movable tables, the top one of which supports a work bearing surface. The multi-table assembly provides further and more detailed mobility and maneuverability to the work bearing surface of the system so as to provide for precise adjustment and positioning of a workpiece situated on the work bearing surface relative to the work face where the workpiece is to be placed. |
