When the Cat excavator is engaged in hydraulic system maintenance, it is essential to select the hydraulic fluids with the appropriate markings.Hydraulic fluids as the core medium driving the movements of excavators, the quality and model of which directly affect the efficiency of the equipment and its useful life.For Cat excavators, it is generally recommended to use hydraulic fluids No. 30 or No. 46 certified at the Caterpillar former plant, the type to be applied, to be determined on the basis of the actual condition of the excavator, the ambient temperature and the recommendation of the manufacturer.Hydraulic fluids are selected not only to meet equipment requirements, but also to focus on key indicators such as their wearability, oxidability, cryogenic fluidity and viscosity.For example, if your Cat excavator works mainly in high temperature environments, it may be necessary to select No. 46 hydraulic fluids to provide better lubricating and cooling effects; conversely, working in cold conditions, it may be necessary for No. 30 hydraulic fluids to ensure its mobility at low temperatures.In conclusion, in order to ensure the proper functioning of Cat excavators and to extend the life of their hydraulic systems, it is important to select suitable hydraulic oil models, as recommended in official manuals or in consultation with specialized technicians.Please note that the regular replacement of hydraulic fluids and the use of formal channels for the purchase of high-quality hydraulic fluids also have a significant impact on the overall performance of excavators.
