Notes about Hydraulic System of Hoisting Equipments
1. If hydraulic oil is under scribed line, you need to add more. And the oil should be injected by filter screen. It should be noted that water and different oil types can’t be replenished.
2. Filter element of the strainer need to be check after 250 hours working time. Some while, rinse and change is necessary.
3. Clear away water and impurities of hydraulic oil container every other half month and change the whole oil every other year or working for 2000 hours. If the oil is not degenerative, drain period can be prolonged appropriately. On the contrary, if the hoisting machines are applied under odious condition, the drain period should be shortened correspondingly.
4. Each valve for hydraulic system can’t be changed at random because all of them have been fully tested and pressure & flow adjusted before leaving factory.
5. Sticking dirt is forbidden for all kinds of machine parts, especially the devices for hydraulic system. After operation, it is necessary to clear away all the dust and grease dirt.
