This invention relates to a conveyor belt arrestor system (1) and more particularly, but not exclusively to a conveyor belt arrestor (9A, 9B) for use in arresting a conveyor belt used in mining operations in case of failure of the belt (2). The invention relates to a conveyor belt arrestor system comprising a first arrestor (9A) having belt arresting means (16, 17) movable between an open position in which a belt (2) moves freely with respect to the arrestor (9A) and a closed position in which a belt (2) is secured by the arresting means (16, 17) and a second arrestor (9B) having belt arresting means (24, 25) movable between an open position in which a belt (2) moves freely with respect to the arrestor (9B) and a closed position in which a belt (2) is secured by the arresting means (24, 25), the second arrestor (9B) having activating means (30-33), when activated allowing the movement of its arresting means (24, 25) from its open to its closed positions and the activating means (24, 25) being activated when the arresting means (16, 17) of the first arrestor (9A) moves from its open to its closed position. |
