Abstract (en)

A handrail is placed around the top of the silo perimeter. The lowering of each person into the silo (1) is assured by two anchoring points located on the handrail. The silo internal perimeter is divided into as many sectors as there are persons so as to define a vertical displacement space for each person. Oxygen is supplied to each person through supply pipes (5). An Independent claim is also included for the apparatus for maintaining silo.

Abstract (fr)

La présente invention concerne un procédé d'entretien d'accumulateurs (1) de matières tels des silos pour matières pulvérulentes dans lesquels s'introduisent une ou plusieurs personnes d'intervention (3). Selon l'invention, on met en place au moins une main courante sur tout le pourtour intérieur de l'accumulateur (1) par fixation sur les parois (2) dans leurs parties hautes ; on assure chaque personne (3) dans son mouvement vers la base de l'accumulateur (1), depuis le haut de l'accumulateur (1), par au moins deux points d'ancrage situés en haut de l'accumulateur (1) et dont l'un au moins est réalisé sur la main courante. On divise le pourtour intérieur de l'accumulateur (1) en autant de secteurs qu'il y a de personnes (3) de façon à définir un espace vertical de déplacement distinct pour chaque personne (3), afin de permettre un travail en parallèle de plusieurs personnes d'intervention dans des conditions favorables de sécurité. L'invention concerne également une installation pour la mise en oeuvre du procédé. Application aux activités d'intervention dans des conditions difficiles. <IMAGE>
