The quality of the small crane hydraulic system will directly affect the performance and service life of the small crane. How should the small crane hydraulic system be maintained? The following suggestions are for reference only:
1. The various valves of the hydraulic system have been fully tested before leaving the factory, and the pressure and flow have been adjusted. Do not touch them casually.
2. Before the operation, the hydraulic tank level gauge should be used to determine whether the hydraulic oil is added according to the regulations. If it is lower than the specified engraved line, it must be supplemented.
3. When refueling, be sure to inject through the oil filter, and be careful not to mix different grades of oil or water and other impure impurities.
4. After the oil filter element is working for 250h, it should be inspected and cleaned or replaced if necessary.
5, all kinds of parts, especially the small crane hydraulic system, all equipment should not be attached to dirt. Be sure to remove dust and oil after work.
6. The hydraulic oil tank should remove moisture and impurities from the bottom oil discharge port every half month;
7. After long-term work, hydraulic oil will produce some condensed water and sediment, which should be discharged once a month.
8. Replace all hydraulic oil every other year (or work over 2000h) (in the case of oil deterioration, the oil change interval can be extended).
9. When the small crane is working in a particularly harsh environment, the oil replacement cycle should be shortened accordingly.
10. Discharge condensate should be carried out after the small crane stops working overnight. Unscrew the drain plug at the bottom of the tank to allow dirty oil to flow until it sees clean oil. Then install the drain plug and add fresh hydraulic oil.
11. No matter how long the working hours are, the hydraulic oil should be updated at least once a year to prevent the oil from deteriorating and polluting the hydraulic system of the small crane.
12. Start the engine before changing the oil, and warm the hydraulic oil to facilitate the discharge.
