It is best to add a protective cover when the pulley is working

Pulleys are often used in drilling in the coal industry. When working, drilling crews use angle steel, iron plates, mesh and other materials to make a pulley safety shield that meets the safety standards for underground drilling rigs. Why? 

Since the clutch pulley guard installed on the rig is easily deformed due to pressure or severe vibration during use, and the protection is not comprehensive, the outer drain of the output shaft of the clutch pulley motor is likely to cause personal injury to personnel.

The safety cover on the pulley overcomes the technical problems that plague the safe operation, effectively improves the safety and reliability of the downhole drilling rig, improves the work efficiency, and ensures the safety of personnel.
