Barre de treuil servant à l'enroulement dans un treuil. Le treuil comporte un tambour ayant une paroi annulaire et une ouverture circulaire. Une série d'ouvertures pour y insérer la barre du treuil se prolongent diamétralement à travers le tambour sur les côtés opposés de la paroi. La barre présente une portion externe dont les dimensions lui permettent de s'étendre à travers les ouvertures. Elle comporte également une portion interne plus large que les ouvertures, ainsi qu'un premier épaulement entre la portion interne et la portion externe. La portion externe comprend une pointe externe qui s'effile vers l'extérieur. Un premier segment de section réduite, qui est adjacent à la pointe, est calibré pour recevoir la paroi sur le premier côté du tambour. Un second épaulement se trouve entre la pointe et le premier segment. Un second segment de section réduite, qui est adjacent au premier épaulement, est calibré pour recevoir la paroi sur le second côté du tambour. La barre présente un troisième segment ayant une section plus large que les premier et second segments et située entre ces derniers. Le troisième segment est calibré de manière à s'ajuster dans l'ouverture centrale du tambour entre les premier et second côtés de la paroi annulaire.
