Abstract

Perfeccionamientos en dispositivos elevadores para estructuras moldeadoras de hormigón, del tipo de dispositivo que comprende; un par de mandíbulas, que tiene cada una con configuración en forma de gancho vuelto hacia dentro; un eje en el que se monta cada una del par de mandíbulas y en el que se asegura una del par de mandíbulas de tal manera que el señalado par de mandíbulas guarda una relación abisagrada una con otra; un asa elevadora asociada con una primera del para de mandíbulas; un mango asociado con la segunda del par de mandíbulas anteriormente citado; caracterizados porque las configuraciones en forma de gancho vuelto hacia dentro de las mandíbulas tienen puntas redondeadas en el extremo interno de cada mandíbula cuyas puntas que están próximas la una a la otra cuando las mandíbulas se hallan en sus posiciones cerradas; porque las puntas se hallan debajo del eje, y el asa elevadora se halla encima del eje; y la longitud de cada una de las mandíbulas es substancialmente igual de una a otra, de tal manera que las puntas son substancialmente coextensivas a todo lo largo de las mismas.
