Abstract: The stabilization strut comprises at least two coaxial tubular elements (respectively an upper element and a lower element) which are telescopically assembled together, together with an extension system for moving the lower element axially towards or away from the upper element. The upper element is pivotally mounted about a pin carried by the structure, and pivoting movement of the strut is controlled by a pivot system hinged to the structure about a pin and actuated by the extension system for the strut. The invention is applicable to stabilizing equipment shelters, for example.

Abstract: The present invention relates to an articulated vehicle comprising a first frame assembly including a first pair of road wheels; an upwardly protruding vertical pivot fixed to the first frame assembly; a second frame assembly including a substantially horizontal beam having a first and a second ends, with the first end being formed with bearings mounted on the pivot and with the beam extending horizontally above the first frame assembly, a support fixed to the second end of the beam, the support including a second pair of road wheels; apparatus to rotate the second frame assembly about the pivot relative to the first frame assembly; a boom pivoted to the second frame assembly about a horizontal axis; apparatus to raise and lower the boom relative to the second frame assembly; ground engaging elements to support said vehicle; connectors to connect ground engaging elements with the first frame assembly while permitting vertical displacement of the ground engaging elements relative to said first frame assembly;

Abstract: The present invention relates to a self-stabilizing load lifting and handling vehicle, wherein the chassis thereof is composed of two elements bearing, respectively, the rear axle and the front axle, these two elements being pivoted on each other about a horizontal pivot pin located above and parallel to the axles, in linear travel position.

Abstract: Stud bolts are threaded into the body of a nuclear reactor vessel and tenned by exerting forces on tensioning nuts located on the upper end of the studs. While the studs are under tension, a cover is attached to the vessel by tightening nuts on the studs against the cover. The tensioning nuts are applied to the studs by immobilizing the studs axially and rotationally, and rotating the tensioning nuts with a pair of driven, diametrically opposed striking rollers. External threads on the striking rollers, external threads on the nut and internal threads on the nut all have the same pitch so that the threads on the striking roller remain engaged with the external threads on the nut as the nut moves axially while being threaded onto the immobilized stud.
