    During the use of the crane, it is necessary to pay attention to the maintenance of each component system and operate in accordance with the regulations. If the hydraulic pump is replaced by a 12-ton crane, what problems should be paid attention to?
    1. Pay attention to anomalies at any time. When an anomaly is found, immediately get a circuit diagram to see if the anomaly is caused by a temporary error.
    2. After the hydraulic pump is started, it performs idling for about 10 minutes to 30 minutes without load for a period of time), especially when the temperature is very low, it is necessary to go through the warm-up process to make the hydraulic circuit circulate normally and then load, and confirm the operating condition.
    3. Pay attention to check the change of the high and low oil temperature of the 12-ton crane, and find out the relationship between the oil temperature and the external ambient temperature, so that you can know whether the storage tank capacity is compatible with the surrounding conditions and the use conditions.
    4. Pay attention to the noise of the hydraulic pump: the new hydraulic pump has less initial wear and is easily affected by air bubbles and dust. Poor lubrication at high temperatures or overloading the use conditions will cause bad consequences and make the hydraulic pump abnormally affected.
    5. Pay attention to the adjustments in the valves of the 12-ton crane, understand the use of pressure control valves, flow control valves and directional control valves, and pay special attention to the adjustment range and limits. Editor: A
