Maintenance and inspection of lifting chains · Lubrication: Apply high-viscosity lubricant regularly, focusing on the areas where the chain links come into contact. · Inspection: Regularly check whether the sprockets are aligned properly and whether the tension of the chain is appropriate. If the chain has stretched, remove even-numbered links symmetrically. In general, when selecting a lifting chain, it is necessary to consider the specific operating conditions, weighing factors such as strength grade, material, and specifications, while also adhering strictly to safety regulations and maintenance requirements.
