Viscosity grade: Viscosity grade is an important parameter for selecting lubricating oil, which directly affects the lubrication effect. The higher the rotational speed of construction machinery, the higher the viscosity requirements for lubricating oil. Therefore, it is necessary to determine the appropriate viscosity grade based on the specific situation of the construction machinery.

Extreme pressure performance: The working conditions of construction machinery are often harsh, such as heavy loads, high speeds, etc., which can cause great pressure on lubricating oil. Therefore, it is necessary to pay attention to the extreme pressure performance of lubricating oil, that is, its load-bearing capacity under high pressure.

Antioxidant performance: The working environment of construction machinery is often harsh, which requires lubricating oil to have good antioxidant performance and be able to work stably in harsh environments.

Anti emulsification performance: Construction machinery often produces impurities such as water vapor and dust during operation, which requires lubricating oil to have good anti emulsification performance and effectively resist the invasion of these impurities.

Usage scenario: If construction machinery equipment operates in high temperature, high humidity, and high pressure environments, it is necessary to choose higher quality and more targeted lubricants.

In short, when choosing lubricating oil for construction machinery, multiple factors such as product structure, viscosity grade, extreme pressure performance, antioxidant performance, and emulsion resistance need to be comprehensively considered. At the same time, the most suitable lubricating oil should be selected according to specific usage scenarios to achieve the best lubrication effect and maintain the best state of construction machinery.
