<p>Device at tool holder ( 10 ) of the kind comprising an essentially C-shaped frame preferably having a long inner range, which frame at its free shank ends carries said tool, for instance a riveting, a glueing or a welding unit. The holder ( 10 ) comprises a truss or frame work, which includes an outer and an inner C-shaped frame ( 11, 23 ) and a number of slewing brackets ( 27-32 ) connected to these. The frames ( 11, 23 ) and the slewing brackets ( 27-32 ) are arranged to form a number of connected triangular sections, which connection points ( 18-22, 37 ) are designed as intersections or joints. The outer C-shaped frame ( 11 ) is arranged only to support thrust forces and the inner frame ( 23 ) thrust and tensile forces and the slewing brackets ( 27-32 ) substantially tensile forces.</p> |
