Abstract
The traction system comprises a plurality of substantially parallel tendons (2) movable for pulling a load, the tendons being disposed according to a pattern in a plane perpendicular to the tendons; and at least one deviator (3) for guiding the tendons, the deviator accommodating an angular deflection of the plurality of tendons. The deviator includes a support structure (4) and a plurality of segments (5) each having an inner surface facing a convex surface of the support structure, front and rear surfaces and a plurality of channels extending from the front surface to the rear surface. The channels are disposed according to said pattern in the front and rear surfaces of each segment, each tendon being received in a respective one of the channels. At least some of the segments (5) have their inner surfaces bearing on the convex surface of the support structure (4) in response to tensile forces applied to the tendons.
