Abstract
Pince de serrage sur un support allongé, du type à corps extérieur et mâchoires, avec pour chaque mâchoire un sabot avec face d'appui sur une face inclinée du corps extérieur et au moins un rouleau interposé entre le sabot et une face inclinée externe de la mâchoire, la pince comportant par ailleurs des moyens d'application des faces d'appui les unes sur les autres, par déformation d'éléments élastiques. L'effort de serrage est assuré par un moyen de déplacement longitudinal des faces d'appui sur les mâchoires par rapport aux faces d'appui sur le corps de réaction. L'invention s'applique au déplacement de charges le long d'un câble ou au blocage d'un pont roulant sur ses rails.
