Title
(EN) A LIFTING DEVICE AND METHODS OF OPERATING A LIFTING DEVICE
(FR) DISPOSITIF DE LEVAGE ET PROCÉDÉS D’UTILISATION D'UN DISPOSITIF DE LEVAGE
Abstract
(EN)
A lifting element, such as for a vessel or vehicle, comprising a lifting element, such as an oblong element, rotated by a number of electrical motors via a rotatable, such as an eccentric, element. The eccentric element ensures that the lifting element can only be tilted within a predetermined angle area increasing the safety thereof. Multiple electric motors are used where one motor counteracts the other within an angle interval to ensure that the tilting element does not tilt undesirably.
(FR)
L’invention concerne un élément de levage, par exemple pour un bâtiment ou un véhicule, comprenant un élément de levage, tel qu'un élément oblong, entraîné en rotation par un certain nombre de moteurs électriques par l'intermédiaire d'un élément rotatif, tel qu'un élément excentrique. L'élément excentrique garantit que l'élément de levage ne peut être incliné que dans une zone angulaire prédéterminée, ce qui augmente sa sécurité. De multiples moteurs électriques sont utilisés, un moteur s'opposant à l'autre dans un intervalle angulaire pour s'assurer que l'élément d'inclinaison ne s'incline pas de manière indésirable.
