Development of New Type Anchor

In the present report we have studied the method of improving the holding ability of anchor. We mainly pay attention to three characteristics of anchor, that are tripping ability, stability and holding power. The results may be summarized as follows. * In the condition that anchor is laid on ground, to leave gap between ground and the anchor except tripping part and bills improves tripping ability. * To minimize the width of tripping part improves stability and holding power. * To attatch wings like wedge to the shoulder improves stability remarkably. Using these results we have produced trial model anchor. And we have ascertained the excellent performance of the new type anchor.
