Abstract

L'invention concerne un ensemble de freinage pour tambours de levage de grues et appareils analogues. Dans une grue de levage 10 comportant une cabine 12 et une flèche 14 articulée sur un axe horizontal 15, un tambour de levage 18 comporte un tambour de freinage 25 sur lequel est monté l'ensemble de freinage de l'invention L'ensemble comprend un collier entourant le tambour de freinage, un cylindre hydraulique mécaniquement relié au collier, un maître-cylindre raccordé à une source de fluide et sur lequel est articulée une pédale de frein 38, et un simulateur hydraulique qui est disposé entre le maître-cylindre de freinage L'invention permet de passer des charges lourdes aux charges moins lourdes sans pour autant nécessiter un réglage du collier.
