    摘要: A workbench, in particular for welding and structural steel work, includes a frame assembly having opposing axial ends and including a pair of traverses respectively disposed at the axial ends, and a pair of spaced substantially parallel platforms for forming working surfaces for installation and placement of workpieces, with the working surfaces being expandable in all directions by retractable or detachably secured elements. One of the platforms is stationarily fixed on the traverses and the other one of the platforms is movably supported on the traverses for displacement in direction of the stationary platform. Extending laterally of the stationary platform is a support unit for attachment of accessories and including at least one support and a guide bar secured to the frame assembly and configured of polyhedral cross section for guiding the support in longitudinal direction.
