Abstract:
A safety arrangement for a manually operated soil compaction roller, havinga travel lever (3) determining the travel direction and speed and movable forward (V) and backward (R) as viewed in the travel direction of the roller; an adjusting element (7) coupled to the travel lever (3) via a first coupling (6) and intended for transmitting the travel-lever position to an actuating device (9), the adjusting element (7), when not loaded by the travel lever (3), being preloaded in a center position corresponding to zero travel speed; a safety actuator (12, 13) which is arranged so as to be movable between an operating position and a hazard position and is preloaded in the operating position and by means of which the first coupling (6) is separable in the hazard position; and a second coupling (17, 18) of travel lever (3) and adjusting element (7), by means of which, when the first coupling (6) is separated, forces can be transmitted only during forward movement of the travel lever (3).
