摘要

Improvements introduced in the object of the main Patent no. 322.023 by: Hydraulic Suspension Lifter, characterized essentially by a hydraulic motor whose shaft is a pinion, drag a crown firmly attached to a drum, which achieves the rotation of the hollow drums, conical surfaces, these two conical drums are connected by their vertices, making contact with a spherical cap, in this way while said drums rotate, the conical surfaces of these can approach or move away adapting to the thickness of the fishing net, which passes through the dragging throat comprised between said surfaces, that is to say, the arrangement of said spherical bushings allow the articulation of the drums while they rotate, likewise said bushing is hollow, in order to accommodate a crosspiece orientable in all directions, by which the second drum is dragged, making both rotate in tandem, said crosshead is firmly attached to the two drums through a housing disposed in the recessed vertices thereof, allowing perfectly and without extortion, that the axis of each drum be inclined forming a certain angle between them, whose variation depends on the weight that gravitates on said spherical bushing, resulting from it that the mentioned angle is greater or smaller.
