The role of anchor is: stopping in the anchor maintenance, to find the exact location of the ship docked direction, played a strong fixation. More Xueyuan certain sense: a man must be stable. Anchor generally refers anchor, it is the main component of the anchoring device. Stopping iron utensils, and even with chains on board, left bottom, you can make the boat stops. [1] The ancient anchor is a large stone, or baskets filled with stones, tied one end of the rope into the water, the boat moored with its weight. Later Woodpaw stone anchor that line both sides of the stones Woodpaw, by weight and grip the boat moored. China Southern has been recorded on a metal anchor. Ancient Chinese sailing a four claw anchor, anchor this excellent performance, are still used on the sampan and boat. I undertake large vessels at home and abroad with the anchor (150,000 tons, etc.) repair and maintenance and marine accessories. When broken down, the speed can not be too fast to slow down the anchor, too fast will lead to difficult stopped anchors and cables could damage the windlass, may even have other serious consequences. The first is the anchor crown bottom anchor and anchor body lying, then at equilibrium lever action, fluke tip will hit bottom, but not caught in the sand. Boats will continue to lay down a certain length of chain, so that most chains are tiled on the seabed. Then back EMU, will anchor back slightly dragging anchor claw D in the body under the action of gravity and anchor chain tension, is inserted in the sand. At this point, the ship will resume some little chain. In general, the release of chain length should be 3-5 times the water depth. Chain is too long, roundabout range is increased ship, easy to collide with other anchored boats. Chain is too short, easy to anchor itself up affecting small anchors that anchor loose anchor role, losing grip effects. After the anchor scratched, the equivalent of playing a pile, and after the drop anchor chain, basically only the sediment level of tension at this point, the anchor grip is the greatest. Unless great storms, generally can grip anchors. Anchors | Chen Hua machinery | Anchor maintenance provided by the China Machinery Co., Ltd. Qingdao Chen. Qingdao Chen Hua Machinery Co., Ltd.
