ABSTRACT:
An arrangement of tensile elements and rollers provides support for an extensible part against forces occurring in two directions perpendicular to the extension direction in which the extensible part is carried by a carrying part of conforming geometry. Two wire ropes form the tensile elements. First ends of each rope are attached to the top corners of one end of the carrying part and second ends of each rope are attached to the opposite bottom corners of the other end of the carrying part. The ropes extend in the extension direction from their carrying part attachments to the extensible part. At the extensible part, the ropes are passed over pulleys in two directions substantially transverse of the extension direction.
