<p>A device enabling a mass (1) cantilevered from an element (2) which is vertically moveable under the effect of thermal expansions and contractions to rest against a fixed framework (9). The device comprises a first arm (7) articulated on a point (C) of the vertically moveable element, a second arm (6) articulated firstly to one end (B) of the first arm adjacent to the mass and slidably placed on this junction, and secondly to the fixed framework, and a third arm (8) articulated firstly to one end (2) of the first arm adjacent to the vertically moveable element, and secondly to the fixed framework (9) at a point (D) at a level different from that of the point (E) at which the second articulated arm is articulated thereto. The invention is applicable to the manifolds of boilers or steam generators.</p> |
