Abstract

Una grua de propositos multiples, transportable que incluye una plataforma (50) que tiene soportes (52) colocados en los extremos opuestos de la misma. Una plataforma giratoria (54) está montada giratoriamente a la plataforma (50) entre los soportes (52) en los extremos opuestos de la plataforma (50 y tiene un eje central de rotacion (55). Un aguilon o brazo elevador (56), que tiene un primer extremo y un segundo extremo está montado pivotalmente a la plataforma giratoria (54) en su primer extremo y el segundo soporta un primer dispositivo que transporta la carga (83). EL aguilon elevador (56) señala en una primera direccion con respecto al eje central de rotacion (55) y es un brazo o aguilon telescopico. Un aguilon superior (64), que tiene un primer extremo y un segundo extremo, tiene su primer extremo montado pivotalmente al segundo extremo del aguilon elevador (56). El segundo extremo del aguilon superior (64) soporta un segundo dispositivo que transporta la carga (89). El aguilon superior (64) que señala en una segunda direccion opuesta a la primera direccion, son respecto al eje central de rotacion (55) y es un brazo o aguilon telescopico. Al proporcionar el aguilon elevador (56) y al aguilon superior (64) de tal manera que el aguilon elevador (56) sirve como un contrapeso, cuando el segundo elevador (56) sirve como un contrapeso, cuando el segundo dispositivo que transporta la carga (89) trasporta una carga y del tal manera que el aguilon superior (64) sirve como un contrapeso, cundo el primer dispositivo que transporta una carga, la grua no necesita un contrapeso separado.
