These factors need to be considered when selecting lubricating oil for wire rope electric hoists

Lubricating oil plays multiple important roles in the operation of wire rope electric hoists, including reducing friction, sealing protection, preventing pollutant invasion, and rust prevention. Therefore, choosing the appropriate lubricating oil is crucial for the efficient operation of wire rope electric hoists. Here are several key factors we need to pay attention to when selecting lubricants:

1、 Temperature influence: In high temperature environments, lubricating oil with high viscosity and ignition point should be selected to ensure that it is not easily oxidized; In low-temperature environments, lubricating oil with lower viscosity and pour point should be selected to avoid reduced fluidity at low temperatures.

2、 Humidity factor: If the working environment of the wire rope electric hoist has high humidity, it is recommended to choose lubricating oil with strong anti emulsification, oil and rust resistance as much as possible. Because the lubrication performance of lubricating oil will decrease when it comes into contact with water, and environments with high humidity can easily lead to moisture entering the lubrication system.

3、 Location factor: For low clearance wire rope electric hoists, attention should be paid to whether the viscosity of the lubricating oil or grease is suitable. If lubrication is required on surface parts such as hooks and chains, lubricating oil or grease with high viscosity and less likely to be lost or wasted should be selected. For parts with high friction speed, lubricating oil with lower viscosity should be selected as much as possible to reduce friction.

Choosing the appropriate lubricating oil for wire rope electric hoists requires attention to multiple aspects. Scientific and rational use of lubricating oil can help improve the operating efficiency of wire rope electric hoists, reduce friction and wear, and extend the service life of equipment. In practical operation, it is necessary to comprehensively consider the specific working conditions and equipment models.
