Problems solved by technology

With regard to a pair of lifting straps, it is necessary to increase or decrease the interval of the lifting straps according to the size of the ship, and the existing yacht lifting device does not have a unit for adjusting the interval of the lifting straps, so it is not suitable for lifting a variety of lifting straps. type of ship
In addition, when the existing yacht lifting device lifts the ship, the belt obliquely pulls the wire rope connected to the belt along the streamlined shape close to the lower part of the ship, so the wire rope twists and twists.
As mentioned above, if the ship is repeatedly lifted while the wire rope is twisted, the fatigue of the wire rope will increase, so the problem of wire rope damage will occur

Abstract

The invention discloses an ocean travelling crane. The ocean travelling crane comprises a crane winch, which is provided with a plurality of layers of steel wire ropes in a coiled manner; a rotating guiding roller, which is used to guide the steel wire ropes coiled to the crane winch or unreeled steel wire ropes, and rotates at predetermined angles along with the changing of the layers of the steel wire ropes coiled on the crane winch. The ocean travelling crane is used to prevent the twisting of the steel wire ropes between the crane winch and the roller or the steel wire ropes from disengaging from the roller, and therefore damages on the steel wire ropes and parts contacted or connected with the steel wire ropes.

Description

technical field [0001] The present invention relates to marine mobile cranes. Background technique [0002] Usually, the yacht lifting device is set at the wharf or seaside of the fishing village, the dock (Dock, ship canal), etc. (hereinafter collectively referred to as "dock"), and the ship is hoisted to the sea or the ship at sea is transported to the breakwater or on land for repair and maintenance. Maintain fishing boats, hide the boats to a safe place in case of bad weather, to prevent damage and sinking, etc. [0003] The prior art about this yacht hoisting device has the "fixed fishing boat crane" of Korean authorized patent No. 10-0503918 and the "crane" of Korean authorized patent No. 10-0853291. However, the above-mentioned prior art is limited to lifting small and light small ships by means of cantilever beams, and cannot lift ships above the small and medium-sized class, not only that, but also cannot lift high-level ships or yachts with complex structures, due...
