The hydraulic system of the ship crane is one of the crucial loading and unloading equipment on board, and its stable operation directly affects the operational efficiency and safety of the ship. Therefore, regular inspection and maintenance of the hydraulic system of the crane are particularly important.

When inspecting the hydraulic system of the crane, we first need to pay attention to the condition of the hydraulic oil. As the working medium of hydraulic systems, the quality and cleanliness of hydraulic oil directly affect the operating efficiency and service life of the system. Therefore, we need to regularly check the color, odor, and viscosity of hydraulic oil to ensure that it meets the usage requirements. At the same time, we also need to regularly replace the hydraulic oil to avoid problems such as oil aging and contamination that may affect the system.

In addition to checking the hydraulic oil, we also need to pay attention to the operation of various components in the hydraulic system. For example, as the power source of a hydraulic system, the operating status of a hydraulic pump directly affects the stability and reliability of the system. Therefore, we need to regularly check the operating noise, temperature, and vibration of the hydraulic pump to ensure that it is in normal working condition. At the same time, for hydraulic motors, hydraulic cylinders and other actuating components, we also need to check their sealing performance, flexibility and wear to ensure that they can function properly during operation.

During the inspection process, we also need to pay attention to the pipeline connections of the hydraulic system. If there are leaks, looseness, and other issues at the pipeline connections, it will have a serious impact on the operation of the system. Therefore, we need to regularly check the sealing and fastening of pipeline connections to promptly identify and solve problems.

In addition, we also need to inspect the control system of the crane hydraulic system. The control system is the brain of the hydraulic system, and its stability and reliability directly affect the overall performance of the system. Therefore, we need to check the operation of electrical components, sensors, and actuators in the control system to ensure that they can accurately and quickly respond to control commands.

Finally, during the inspection of the hydraulic system of the crane, we also need to pay attention to safety issues. Due to the high pressure, high speed and other hazardous factors involved in hydraulic systems, we need to comply with relevant safety regulations and operating procedures when conducting inspections to ensure our own and others' safety.

In short, the inspection of the hydraulic system of the ship's crane is a meticulous and complex task. Only through comprehensive inspection and timely maintenance can the stable operation of the system and the safety of ship operations be ensured.
