Abstract

L'invention a trait à des dispositifs de sécurité pour un appareil élévateur et abaisseur de charge Au moins un curseur 12 possède, monté à pivotement sur lui, un cliquet 14 auquel un câble est attelé par l'intermédiaire d'un élément 19 monté à coulissement sur le cliquet et sollicité par ressort vers le curseur. Lorsque la tension du câble est relâchée, l'élément 19 est poussé vers le curseur provoquant une rotation du levier 30 et soulevant le rouleau de verrouillage 41 pour bloquer le cliquet dans le curseur. Application notamment aux élévateurs arrière de véhicules.
