Abstract

Le système d'élévation dissocie les fonctions de suspension et de traction et comprend par conséquent deux poulies; une poulie de suspension conçue pour supporter le poids de la cabine elle-même et le contrepoids, et une autre poulie de traction qui génère uniquement la force pour déplacer le déséquilibre qui existe entre la cabine et le contrepoids. La poulie de traction peut être raccordée directement à un moteur (sans engrenage) ou peut être connectée à un moteur réducteur. Chaque poulie possède des câbles de suspension et de traction indépendants les uns des autres. La dispositiion d'une poulie de suspension et d'une autre poulie de traction permet de réduire considérablement la dimension du moteur, de concevoir le système d'élévation selon le souhait du client, d'intégrer rapidement les avantages dans l'installation et d'améliorer les installations existances, tout en simplifiant la maintenance et en garantissant la sécurité à tout moment.
