It is understood that the ship-borne crane is an auxiliary lifting device fitted on various types of ships. It is usually installed on the deck or in the cargo compartment for the hoisting and transportation of small boats, materials and equipment. The aircraft has been granted a utility model patent by the State Intellectual Property Office.
As a professional R&D and production enterprise of truck-mounted cranes and special-purpose cranes, Stone Coal Machine Company has many years of experience in designing and manufacturing mechanical equipment, and has undertaken the national “863†project. "The 'increasing speed ship-borne crane' developed this time has a compact structure and realizes full hydraulic drive. The power source is also directly provided by the motor pump station, and the operation is simple and convenient.
Ferro-tungsten iron alloy series (tungsten content: 70%-80%) is an alloy composed of tungsten and iron, which is used as an alloy additive for steelmaking. Commonly used ferrotungsten contains 70% tungsten and 80% tungsten.
Ferrotungsten is prepared from wolframite by carbon reduction in an electric furnace. Mainly used as alloying element additive for tungsten-containing alloy steel (such as high-speed steel). There are three varieties of ferrotungsten produced in my country, including W701, W702, and W65, and the tungsten content is about 65-70%. Due to its high melting point, it cannot flow out in a liquid state, so it is produced by agglomeration method or iron extraction method.
