Abstract

La invención es una mejora en la máquina tal como una 'pala' para minado de superficie que tiene un brazo, un cucharón excavador en forma de cubeta y un tensor. El último se utiliza para mantener el 'ángulo de inclinación' entre el brazo y el cucharón excavador. El tensor tiene primera y segunda argollas y se extiende entre el brazo y el cucharón excavador. La mejora comprende un collarín en forma de tubo interpuesto entre las argollas que conecta a las mismas. Por lo menos la primera argolla extrema es posicionalmente ajustable con respeto al collarín por lo que el 'ángulo de inclinación' entre el brazo y el cucharón excavador se puede seleccionar fácilamente. En una modalidad altamente preferida, cada argolla extrema está enroscada a un extremo opuesto del collarín y se obtiene un mejor ajuste de 'vernier' del ángulo de inclinación.
