As important components of ship equipment, there are significant differences in the technical characteristics and application scenarios between marine cranes and lifeboats. Marine cranes are mainly used for cargo loading and unloading operations, and their technical characteristics are mainly reflected in high load-bearing capacity, accurate operation, and intelligent control.

　　For example, marine cranes adopt advanced hydraulic and electrical control systems, making the operation of the equipment smoother, more accurate, and efficient. In addition, the application of intelligent technologies such as sensors, the Internet of Things, and artificial intelligence enables ship crane equipment to achieve real-time monitoring, fault diagnosis, and intelligent scheduling, further enhancing its safety and reliability.

　　The suspended boat frame is mainly used for the hoisting operation of lifeboats, and its technical characteristics are mainly reflected in its compact structure, easy operation, and safety and reliability. For example, the suspended boat frame adopts a modular design concept, making the structure of the equipment more flexible, easy to install, maintain, and upgrade. In addition, the safe operation and maintenance of the suspended boat frame are crucial. It is necessary to regularly inspect the wear and tear of the steel wire rope, pulley, and hydraulic system, and replace damaged components in a timely manner to ensure the normal operation of the equipment.

　　The development of marine cranes and boat racks will pay more attention to the integration and innovation of technology. For example, the application of 5G communication technology will achieve efficient collaboration between equipment, and green technology is expected to further reduce equipment energy consumption and emissions. In short, the comparative study of ship cranes and boat racks will continue to promote the development of ship equipment towards higher efficiency, intelligence, and environmental friendliness.
