Strict adherence to safety operating procedures is required during the use of drive chains. Operators must be familiar with the equipment's performance characteristics and operating protocols. Before startup, they must verify that the chain, sprockets, tensioning device, and protective guards are securely installed and ensure the drive system is free from looseness, excessive wear, cracks, or other abnormalities. Upon startup, the equipment should run without a load for a short period to observe the chain's stability; normal operation may commence only after confirming the absence of abnormal vibration, noise, or chain skipping.
During operation, it is strictly prohibited to place hands, tools, or other objects near the drive chain, or to remove or open protective guards for adjustments or repairs, in order to prevent accidents such as entanglement or crushing injuries. If chain slack, severe sprocket wear, insufficient lubrication, or abnormal noise is detected, the equipment must be stopped immediately for inspection; operation may only resume after the issue is resolved. Running the equipment with faults or under overload conditions is strictly prohibited.
Routine maintenance-including chain cleaning, lubrication, tension adjustment, and component replacement-must be performed only after the equipment has been fully shut down and the power supply disconnected. Additionally, regular inspections should be conducted to monitor chain elongation, sprocket wear, and the tightness of connecting parts, with timely replacement of components that meet the criteria for retirement. Strengthening daily maintenance and safety management not only reduces mechanical failures and accidents but also enhances drive chain efficiency, extends equipment service life, and ensures the long-term, stable, and safe operation of the machinery.
