Abstract

Una grúa giratoria gemela, montada en una cimentación de grúa gemela, comprendiendo esta grúa gemela dos grúas individuales que tienen cada una un brazo de inclinación variable capaz de seer subido y bajado con cables elevadores que corren hasta los brazos desde chigres situados en o sobre cada grúa, en que cada grúa está montada en un medio de soporte capaz de girar en torno a un eje vertical común y a la misma distancia de él, y en que cada grúa incluye un mecanismo de rotación que engrana en una corona dentada fija común sobre la grúa gemela a fin de proporcionar un movimiento de rotación en torno al eje vertical común, permitiendo que las grúas trabajen por separado o como un par.
