The invention relates to a load-compensating rope sheave arrangement for drum winders, comprising at least two rope sheaves which are vertically guided in sliding frames and mounted on hydraulically short-circuited cylinders. Multiply redundant monitoring of the different sheave loads acting upon the rope sheaves is carried out via the hydraulic cylinders which are connected to the system control of the drum winder for communication.

    L'invention concerne un agencement de poulies compensatrices pour machines d'extraction à tambour, comprenant au moins deux poulies guidées verticalement dans des châssis de coulissement, et montées sur des vérins en court-circuit hyraulique, permettant d'exercer une surveillance à multiple redondance des différentes charges exercées par les câbles sur les poulies, en liaison de communication avec la commande centrale de la machine d'extraction à tambour.
