Do you know what requirements need to be met regarding the oil used in single-girder cranes?

Thread Content

1: To extend the lifespan of the equipment and reduce damage caused by friction between mechanical components. It is best to use hydraulic oil with good wear resistance and lubricity inside single-girder cranes. II: It is best to choose hydraulic oil with good antioxidant stability. The antioxidant stability mentioned here primarily refers to the chemical reaction that occurs between the oil and oxidants as the temperature rises. In real life, when the oil temperature rises by 10°, the chemical effects increase significantly. Hydraulic oils with good antioxidant stability generally do not undergo oxidation and deterioration even over extended periods of time ； Thereby effectively ensuring the normal cyclic operation of the single-girder crane. III: To increase the viscosity of hydraulic oil, experts recommend adding polymer substances to it. Because these substances can reduce molecular chain breaks. IV: Choose hydraulic oil with moderate viscosity. Due to the high viscosity of hydraulic oil, its transportation through pipes results in excessive strain on the entire machine, and it also affects the machine’s no-load capacity. On the contrary, hydraulic oil with lower viscosity provides a poorer lubrication effect. At the same time, the overall efficiency of the machine is not high.
