Pour empêcher un enroulement irrégulier ou excessif d'une sangle au moyen d'une structure simple, l'appareil de levage à sangle comprend un élément servant à empêcher l'enroulement irrégulier, qui est pressé contre la sangle enroulée sur le dispositif d'enroulement, l'élément servant à empêcher l'enroulement irrégulier est mobile de manière à s'adapter aux changements de diamètre du cercle décrit par la sangle, et un moyen de commande sert à régulariser l'entraînement avec l'élément servant à empêcher l'enroulement irrégulier lorsque le diamètre du cercle équivaut à un diamètre donné. De plus, un guide de sangle comportant une partie de guidage de la sangle est supporté entre deux plaques latérales de manière à glisser librement pour permettre l'enroulement de la sangle sur le dispositif d'enroulement.
