Abstract
An accident prevention system for machines having one or more movable components, such as rotatable components, has a cover by means of which access may be had to the movable component and which can be moved to an open position. A latching arrangement normally holds the cover in closed position. An electric circuit is provided including a source of electric energy, a normally open switch and an electrically energizable actuating element which can deactivate the latching arrangement. A detector senses movement of the movable component and, when it determines that the movable component is stationary, completes the electric circuit up to the switch so that when the switch is subsequently operated, the actuating element is actuated and disengages the latching arrangement to permit the cover to be opened.
