FAQs
Question | Answer |
How to select lubricants for bearings and sheave shafts? | Use lithium-based grease (NLGI 2) for bearings and sheave shafts, suitable for -20℃ to 120℃. Refuel every 200 working hours; clean old lubricant before refueling. Avoid mixing different types of grease to prevent performance degradation. |
What is the inspection frequency for critical fasteners? | High-strength bolts (8.8-grade) on sheave sets and ladders: retighten quarterly and inspect monthly. Cotter pins and spring washers: check daily; replace immediately if rusted, deformed, or sheared. Follow GB torque standards for retightening. |
