Abstract

Treuil de frein à disque mécanique portatif se rapportant spécifiquement au domaine technique des treuils et comprenant une base principale (4). L'extrémité supérieure de la base principale (4) est pourvue de manière fixe d'un moteur (3) ; l'extrémité de sortie du moteur (3) est pourvue de manière fixe d'une plaque de tambour de câble (10) ; l'extrémité avant de la plaque de tambour à câble (10) est pourvue de manière fixe d'une bobine de câble (15) ; l'extrémité avant de la bobine de câble (15) est pourvue d'un mécanisme d'embrayage mécanique et d'un mécanisme de frein à disque mécanique ; et le mécanisme d'embrayage mécanique et le mécanisme de frein à disque mécanique sont tous deux disposés à l'extrémité supérieure de la base principale (4). Le treuil de frein à disque mécanique portatif est étroitement intégré à la bobine de câble au moyen du mécanisme d'embrayage mécanique et ne glisse pas. L'utilisation du mécanisme de frein à disque mécanique et l'abandon du frein à huile permettent d'éviter les problèmes de fuite d'huile et de défaillance de frein dus à l'entretien. De plus, le treuil de frein assure un freinage sensible et fiable et une longue durée de vie, ne requiert pas d'entretien, présente une conception de trou en forme de taille, et peut régler la force de frottement entre des plaquettes de frein à disque et des disques de frein à disque sur un ensemble frein à disque. Dans un état d'embrayage, un opérateur peut facilement tirer le crochet d'une grue pour un accrochage sur de longues distances.
