Description

Crane for Refloation of Yacht

The present invention relates to a yacht lifting crane, and more particularly, to a yacht lifting crane capable of performing a lifting operation without moving forward and backward during a lifting operation at a coastal pier or a dock, A lifting device using a speed reducer, a lift chain and a balancing weight; A supporting device which is movable in the vertical direction; And a moving device for moving the four-corner structure and the four-corner structure.

A yacht is a western style small sailing boat that is used for cruising, sailing and racing. The type of yacht is divided into various types according to the use, the structure of the bottom, and the style of the sailboat.

Depending on the application, it is classified as dinghy and cruiser. A dinghy is a small sailing yacht that does not have an engine and a cabin but sails mainly on the wind. The cruiser is 7 ~ 20m deep and has residence and drainage facilities, navigation instruments, amusement facilities, etc., and can navigate to far sea.

Depending on the structure of the bottom, it is possible to use a lee board keel, a center board keel, a fin keel, a bulb keel, a heavy keel, a twin keel, And long keel.

A rebound kill refers to a yacht installed on both left and right sides of a board, which is a resistance plate, to prevent lateral forces from being exerted by external forces such as algae or wind.

A centerboard keel is a yacht equipped with a center board that allows you to pierce a keel at the center of the hull and extend and retract it freely.

Finkel is a yacht in which a fin-like metal body is fixed under the hull instead of the center board.

Heavy keel is a yacht attached to the bottom of the yacht as part of the hull of steel, heavy metal material used in large yachts. Bulk Kill is a variant of Pinkle, a yacht with a thin plate-like pin itself consisting of a ballast and a shell-shaped bulb attached to the bottom of the plate.

A twin keel is a yacht with two fins installed diagonally below the hull of the ship at the center of the ship so that the length of the keel is shortened so that the ship can dock close to the land. Longkill is a yacht that corresponds to a typical Western sailboat where the kill itself forms a resistor.

Generally, a yacht lifting device is installed in a fishing pier, a coast, a dock (election), etc. (hereinafter collectively referred to as a "dock") to lift a ship to the sea or to transport a sea ship to a breakwater or land, And it is used to prevent damage and sinking by evacuating the ship to safety zone even in bad weather.
