The lubrication of the wire rope of the stage electric hoist is crucial for extending its service life and ensuring safe operation. The following are some precautions during lubrication: Selection of Lubricants - **Type Compatibility**: Lubricants specifically designed for wire ropes should be selected. Common types include graphite - based lubricants, grease - type lubricants, and synthetic lubricants. Graphite - based lubricants are suitable for high - temperature environments. Grease - type lubricants have good adhesion, and synthetic lubricants have excellent anti - wear and anti - oxidation properties. The selection can be made according to the working environment and requirements of the stage electric hoist. - **Reliable Quality**: Choose lubricants with qualified quality and brand guarantees. Avoid using inferior or expired products to prevent failing to achieve the lubrication effect and instead causing damage to the wire rope. Preparation Before Lubrication - **Clean the Wire Rope**: Before lubrication, it is necessary to thoroughly remove impurities such as dust, oil stains, and rust on the surface of the wire rope using a clean cloth or special cleaning tools. Ensure that the surface of the wire rope is free of debris so that the lubricant can fully contact the surface of the wire rope and achieve the best lubrication effect. - **Check the Condition of the Wire Rope**: Carefully check whether the wire rope has broken wires, wear, deformation, etc. Pay special attention to parts with serious damage, make good records, focus on handling them during the lubrication process, and replace the wire rope in a timely manner if necessary. Lubrication Operation Process - **Apply Uniformly**: Use tools such as brushes or sprayers to evenly apply or spray the lubricant on the surface of the wire rope. Ensure that the lubricant covers every part of the wire rope, especially the gaps between the wire rope and the strands. These parts are easily overlooked but very crucial. The number of applications can be appropriately increased to ensure sufficient lubrication. - **Avoid Over - application**: Although sufficient lubrication should be ensured, also pay attention to avoid applying too much lubricant. Excessive lubricant may attract more dust and impurities,加重 the contamination of the wire rope, and may also drip onto stage equipment or the ground, causing potential safety hazards or cleaning troubles. - **Pay Attention to the Direction**: If applying the lubricant by brushing, the application direction should be consistent with the lay direction of the wire rope. This is conducive to the better penetration of the lubricant into the strands and improves the lubrication effect. - **Strengthen Lubrication of Key Parts**: For parts where the wire rope frequently contacts the drum, pulley, etc., as well as parts prone to wear, such as the bends of the wire rope and the end - fixing parts, focus on lubrication and appropriately increase the amount of lubricant. Maintenance After Lubrication - **Remove Excess Lubricant**: After lubrication, promptly clean the excess lubricant and possible contaminants on the surface of the wire rope to keep the surface of the wire rope relatively clean. - **Regular Inspection**: Establish a regular inspection system to check the lubrication condition of the wire rope. If the lubricant is found to be lost or ineffective, replenish the lubrication in a timely manner. Generally, when the stage electric hoist is used frequently, the lubrication condition can be checked once a week or every two weeks, and lubrication maintenance can be carried out according to the actual situation.

- **Record Maintenance Information**: Keep detailed records of information such as the lubrication time, the type of lubricant used, the lubricated parts, and the condition of the wire rope each time, so as to track the usage of the wire rope and provide a reference for subsequent maintenance and replacement.
