Lubricating explosion-proof electric hoists is an important step in ensuring their normal operation and extending their service life. The following are the specific steps and precautions for lubricating explosion-proof electric hoists:

1、 Lubrication parts and selection of lubricating oil

retarder:

Lubrication method: Inject lubricating oil from the self injection hole.

Lubricating oil selection: 50 # mechanical oil should be used.

Lubrication cycle: lubricate once every six months.

Wire rope and drum:

Lubrication method: Apply the surface and use appropriate lubricating grease.

Lubricating oil selection: Steel wire rope grease is used.

Lubrication cycle: It is recommended to lubricate once a week, especially when used at room temperature. When the temperature is low in winter, the lubricating grease should be heated before application.

Hook pulley bearings/wheels:

Lubrication method: Squeeze or squeeze lubricating oil.

Lubricating oil selection: It is called calcium based lubricating oil.

Lubrication cycle: lubricate once every six months.

Lifting and operating electric motors:

Lubrication method: Apply lubricating oil.

Lubricating oil selection: Calcium sodium based grease lubricating oil should be used.

Lubrication cycle: lubricate once every six months.

2、 Lubrication steps

Prepare lubricating oil and tools: Prepare corresponding lubricating oil, oiler, brush, cleaning cloth and other tools according to the lubrication needs.

Cleaning lubrication parts: Use a clean cloth or brush to remove dust and dirt from the lubrication parts, ensuring that the lubricating oil can fully contact and penetrate the parts that need lubrication.

Apply or inject lubricating oil:

For parts such as reducers and motors that require oil injection, use an oil injector to inject an appropriate amount of lubricating oil from the self injection hole.

For areas such as steel wire ropes and drums that require application, use a brush or gloves to evenly apply lubricating grease to the surface.

Check lubrication effect: After lubrication is completed, check whether the lubrication parts are fully lubricated to ensure that there is no missing or excessive lubricating oil.

3、 Precautions

Avoid excessive lubrication: Overapplying lubricant not only causes waste and pollution, but may also affect the normal operation of the equipment.

Regularly replace lubricating oil: Based on the operation of the equipment and the instructions for using the lubricating oil, regularly replace the lubricating oil to ensure its stable performance.

Pay attention to the cleanliness of lubricating oil: Lubricating oil should be stored in a dry and clean environment to avoid mixing impurities and moisture.

Adhere to operating procedures: During the lubrication process, the operating procedures and safety regulations of the equipment should be followed to ensure safe operation.

Regular inspection and maintenance: In addition to regular lubrication, it is also necessary to regularly check whether various parts of the equipment are operating normally, and if there are any abnormalities, they should be dealt with in a timely manner.
