Wire Rope Marine Crane is a common marine lifting equipment, mainly composed of a boom, a winch mechanism, a slewing mechanism, a variable amplitude mechanism, and a frame. It achieves the lifting and lowering of goods through the retraction and extension of steel wire ropes, while the boom can be adjusted and rotated within a certain range to adapt to different loading and unloading positions and operational requirements. This type of crane is usually installed on the deck of ships and used for cargo loading and unloading operations on various types of ships such as bulk carriers and multi-purpose ships.

　　1. Moderate lifting capacity: The lifting capacity of wire rope marine cranes is generally between 10 tons and 50 tons, which can meet the loading and unloading needs of most bulk carriers and multi-purpose ships.

　　2. High operational efficiency: With fast lifting and lowering speeds, it can effectively improve the efficiency of cargo loading and unloading, and shorten the vessel's stay in port.

　　3. Stable and reliable structure: Adopting a research structure design, it can withstand large loads and harsh marine environments, ensuring stability and safety during long-term use.

　　4. Flexible operation: Equipped with a precise control system, it can achieve flexible amplitude and rotation of the crane arm, as well as precise retraction and extension of the steel wire rope, meeting the loading and unloading needs of different positions and angles.

　　5. Easy maintenance: Key components are easy to inspect and replace, and the design considers factors that facilitate maintenance, reducing maintenance costs and downtime.

　　6. High safety: Equipped with various safety devices such as overload limiters, torque limiters, etc., to prevent overload and equipment damage, ensuring safe operation.
