Abstract

Perfeccionamientos en los equipos de elevación y de manutención, especialmente para trabajar sobre superficies acuáticas, del tipo que comprende por lo menos un dispositivo de maniobra con sus medios motores, para operaciones de elevación y de manutención entre un soporte de dispositivo y una carga susceptibles de un movimiento relativo, caracterizados porque el equipo compense unos medios móviles que están soportados por el dispositivo y que están dispuestos para desplazarse por gravedad y libremente entre dos posiciones extremas, bajo el efecto de dicho movimiento relativo, cuando su parte extrema destinada a cooperar con la carga está fija con respecto a ésta, de manera que comprende la variación de distancia entre la carga y la parte del dispositivo que soporta dichos medios móviles, estando previstos unos medios fijos de tope para una por lo menos de dichas dos posiciones.
