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.
