The mast has a driving unit (3) that is attached to the carriage and has a driving motor (5). A rail (4) is attached to the carriage, and a free partial area is formed directly above the rail when seen in a mounting orientation, where the guide units are guided into an inner area of the rail. The carriage has downwardly extending side walls at opposite sides of the rail, where the rail has a polygonal cross-section, and one of the guiding units is designed as a roller. |
