Abstract

Perfeccionamientos en dispositivos para enhebrar y girar simultáneamente las tuercas de varios pernos roscados, tornillos alargables, anclajes de tracción o similares, compuestos de un anillo soporte con escotes para la recepción de tuercas junto con pernos roscados y grupos de giro independientes, sujetados a ellos, en cada caso para una tuerca, en los cuales el giro se produce por un motor eléctrico reversible en su sentido de giro y que contiene medios adicionales para la sujeción hidráulica de las tuercas, caracterizados porque la tuerca o un apéndice que rodea el perno roscado, unido con la tuerca, forma el rotor del motor eléctrico de clase de construcción asincrona, cuyas piezas de estator, que contienen un arrollamiento de corriente alterna, están desarrolladas en forma de anillo, de sector o de disco y se disponen enfrente de las superficies a la tuerca o bien al apéndice en los escotes del anillo soporte.
