Abstract

Un dispositivo indicador de tensión 1 para un perno de roca 2 donde el dispositivo indicador de tensión 1 comprende una arandela de soporte 5, un miembro de cubierta 6 con un orificio central para recibir una porción posterior del perno de roca 2, y una sustancia indicadora 7 provista en un primer espacio 8. El primer espacio 8 está provisto en el miembro de cubierta 6 o en un receso en la arandela de soporte 5 para enfrentar la tuerca 4. Al girar la tuerca 4, la sustancia indicadora 7 es forzada fuera del primer espacio 8 de tal manera que la sustancia indicadora 7 es visible en la inspección del perno de roca 3, indicando, de esta manera, que el perno de roca 3 ha sido tensado.
