Cranes have many working mechanisms, among which hydraulic systems are commonly used to ensure the normal use of cranes. Today, we will talk about how to maintain the hydraulic system of ship cranes. Come and learn about it.

1. Before starting the homework, it is necessary to check whether the joints of each part are tightly fastened and there should be no oil leakage.

2. The oil filter of the ship crane needs to be checked frequently to see if it is blocked and if the adjustment value of the safety valve changes after use.

3. Before operating the crane, check the oil tank level window to ensure that the hydraulic oil has been fully filled according to regulations. If it is below the specified line, it should be replenished in a timely manner.

4. After the hydraulic system of the ship crane enters a stable operating state, attention should be paid to the oil temperature, pressure, and other conditions at all times, and the hydraulic cylinder should also be checked in a timely manner.

5. If the crane operates in harsh environments, the oil replacement cycle should be shortened. Long term operation of hydraulic oil will produce sediment, and it is recommended to discharge it once a month.
