Abstract

L'invention concerne un ascenseur permettant d'inspecter les cloisons d'un bateau. Cet ascenseur comprend un mécanisme de levage, une cabine d'élévation, une plate-forme de support et des rails de guidage pour cette plate-forme de support. La cabine d'élévation est placée sur la pointe du mécanisme de levage. Le mécanisme de levage est monté sur la plate-forme de support. La plate-forme de support se déplace sur les rails de guidage. La cabine d'élévation repose contre la cloison par son poids et l'emplacement des rails. La cabine d'élévation peut s'élever et s'abaisser avec le mécanisme de levage, et peut se déplacer horizontalement le long de la surface de la cloison par coopération du mécanisme de levage et de la plate-forme de support sur le rail. Les avantages présentés par cet ascenseur sont sa sécurité, son faible coût et sa grande efficacité. En comparaison de l'art antérieur lequel mettait en oeuvre une grue, il permet d'éviter des désavantages tels que la difficulté d'accès à partir du panneau et la difficulté d'installation et de fonctionnement.
