Stage electric hoists do require regular lubrication to ensure smooth operation and extend their lifespan. The following is a detailed guide for lubrication of stage electric hoists:

1、 The Importance of Lubrication

Regularly lubricating the stage electric hoist can significantly reduce internal friction and wear, lower energy consumption, and improve equipment reliability and service life. Meanwhile, good lubrication can also prevent dust and moisture from entering the interior of the equipment, playing a role in rust and corrosion prevention.

2、 Lubrication parts and lubricant selection

Reducer:

Lubrication method: Inject from the upper oil hole.

Lubricant: GB443HJ50 lubricant or 50 # mechanical oil can be used (specific models may vary depending on the equipment, please refer to the equipment manual).

Lubrication cycle: Generally every three months to six months, the specific cycle can be adjusted according to the equipment usage and manufacturer's recommendations.

Drive device:

Lubrication method: Inject from the upper oil hole as well.

Lubricant: Calcium based lubricating oil.

Lubrication cycle: Generally once a year, but the specific cycle needs to be determined based on the equipment usage and manufacturer's recommendations.

Wire rope and drum:

Lubrication method: Apply to the surface.

Lubricant: Special grease for steel wire ropes.

Lubrication cycle: It is recommended to perform it every half month to one month to maintain lubrication of the steel wire rope and reduce wear.

Hook thrust bearing, pulley, drum, motor bearing:

Lubrication method: Squeeze in lubricating oil or grease.

Lubricant: 3 # calcium based grease or other suitable grease for bearings.

Lubrication cycle: Generally injected every six months or during maintenance, the specific cycle needs to be determined according to the equipment usage and manufacturer's recommendations.

3、 Lubrication precautions

Moderate addition: Lubricant should be added in moderation during lubrication, not too much or too little. Excessive lubricant will increase the internal resistance of the equipment and affect its operational efficiency; However, too little lubricant cannot achieve good lubrication effect.

Cleaning equipment: Before lubrication, clean the dust and dirt on the surface of the equipment with a clean cloth or brush to ensure that the lubricant can be evenly applied to the surface of the equipment.

Choose appropriate lubricant: The appropriate lubricant should be selected according to the specific requirements of the equipment and the manufacturer's recommendations to ensure good lubrication effect and compatibility.

Regular inspection: The lubrication condition of the equipment should be checked regularly. If lubricant deterioration, reduction, or abnormal wear of the equipment is found, it should be replenished or replaced in a timely manner.

4、 Inspection after lubrication

Check lubrication effect: After lubrication, check whether the lubricant is evenly applied to the surface of the equipment and whether the equipment runs smoothly.

Check the equipment status: At the same time, the overall status of the equipment should also be checked for any abnormal noise, vibration, or wear.
