Abstract

Mejoras en la construcción de excavadoras de pala, particularmente adecuadas para la excavación frontal de paredes verticales, caracterizadas por el hecho de comprender un mástil rígido vertical a lo largo del cual puede desplazarse entre dos topes fijos del mástil un patín sobre cuyo extremo inferior está articulada una pala en forma de cuchara con borde cortante, estando montado dicho guía corrediza sobre una armadura susceptible de ser fijada al borde de la excavación y estando previstos medios para provocar el avance gradual de la guía y de la pala con el borde cortante vuelta hacia abajo, así como medios para hacer girar la pala de unos 90º y hacerla subir nuevamente con el carro o patín a lo largo de guía, forma de actuar en el terreno aprovechando el contraste entre pala y guía.
