<p>A hydraulically operated grapple or timber fork provided with a wire tightened on the load to prevent the load from disarranging and falling out of the fork. The wire tension is obtained by a hydraulically operated stretcher. In order to ensure that the wire stretcher in all positions can be supplied with hydraulic fluid under pressure, a pressure accumulator is positioned between a hydraulic pressure source and the hydraulically operated wire stretcher.</p> |
