Marine Deck cranes are the basic equipment for lifting and moving cargo on the deck of a ship. There are many different designs of cranes, but the working principle is basically the same. Cranes have a boom or jib that is hinged to the base and can be rotated. The other end of the jib is connected to a winch for lifting and lowering loads. The winch is operated by a hydraulic system, and the crane operator controls it using a joystick.
Hydraulic ship cranes were first developed in the 1960s.It has good step less speed regulation characteristics: smooth work, change of to the impact of small: lightweight operation; work reliably: long service life: the same output power conditions, it is more than other types of cranes under the same output power conditions, it is lighter and smaller than other types of cranes.
Hydraulic marine crane is a cycle, intermittent action, short-range material handling machinery. A working cycle Including loading, transportation, unloading and return to the original position of the process, that is, the fetching device from the fetching place by the lifting mechanism to lift the material up, by running, slewing, amplitude mechanism to move the material, and then in the designated place to put down, and then carry out the opposite action to Then the opposite action is carried out to make the fetching device return to the original position so as to carry out the next working cycle. There is generally a short break between the two working cycles.Ship cranes should be reliable, efficient, easy to maintain and use, but also should be able to waterproof, moisture-proof and adapt to the navigation areaClimatic conditions.

Specifically, the use of marine cranes are mainly used in the following areas:
1. loading and unloading of goods to better improve operational efficiency:
Marine cranes can quickly and stably lift and unload goods onto or from ships, greatly improving the efficiency of loading and unloading of goods. Compared with the traditional manual lifting methods, marine cranes can save a lot of time and labor costs. Marine cranes play a vital role in the transportation of goods between ships and terminals. Cranes help to move heavy containers, cargo and equipment on and off the ship, especially when the port where the ship is docked does not have specialized equipment for loading and unloading containers. Cranes can lift heavy containers, bulk cargo (such as grains, ores and other materials). For example, on container ships, cranes can lift 20-foot or 40-foot containers weighing several tons and move them from the hold to the dock for further transport.

2. Enhanced operations:Marine cranes have strong lifting capacity and stability, and are able to carry out lifting operations in a variety of harsh sea conditions. At the same time, marine cranes are equipped with protection devices, which can effectively avoid the occurrence of falling goods or accidental injuries and safeguard the operation. In bulk carriers, cranes are used for handling bulk materials. They can use special attachments, such as grabs, to scoop up coal or gravel and transfer it to storage facilities on shore:
For cargoes that are difficult to handle by cranes on the quay or by other means, shipboard cranes provide a flexible solution for lifting and positioning these cargoes.
3. Space saving:Shipboard cranes are usually mounted on the ship’s boom and do not occupy the ship’s internal space, which allows for the limited use of the ship’s loading space. In this way, the ship can carry more cargo and improve the transportation efficiency.

4. Strong adaptability: Marine cranes can be customized and adjusted according to different loading and unloading operational needs, and can adapt to various types and sizes of cargo lifting needs. At the same time, marine cranes are also multifunctional and can be rotated, telescopic and other operations to meet the needs of different operating scenarios. Managing cargo under adverse conditions:In the absence of port infrastructure (e.g., remote areas), cranes enable ships to load and unload cargo directly in open water or in ports with less equipment.
5. Convenient maintenance:Marine cranes adopt advanced design and manufacturing process, characterized by simple structure and long service life. At the same time, the maintenance of marine cranes is relatively simple, only regular inspection and maintenance can be, reducing the maintenance costs and the frequency of cyclical maintenance.

6. Environmental protection and energy saving: marine cranes usually use electric or hydraulic drive system, more environmentally friendly and energy saving than fuel-driven cranes. The use of marine cranes can reduce air
The use of marine cranes can reduce air pollution and noise pollution, reduce the environmental impact of the ship.
7. Enhance the competitiveness of the ship: marine cranes can improve the ship’s throughput and transportation efficiency, shorten the loading and unloading of cargo time, while reducing operating costs and improving economic efficiency, thereby enhancing the ship’s competitiveness.
Overall, marine crane equipment has many advantages such as space saving, adaptability, easy maintenance, environmental protection and energy saving and competitiveness enhancement, which has become an important tool for loading and unloading goods on ships.
With the continuous development and diversified needs in the field of ship transportation, the application prospects of marine crane equipment will be broader, providing more support and protection for ship transportation.
