Maintenance & Care Recommendations

Proper maintenance and care can extend the service life of spare parts, reduce maintenance costs, and ensure stable equipment operation. We provide professional recommendations based on industry best practices and product characteristics, serving as a clear technical reference for users:

• Regular Inspection: Conduct a comprehensive inspection of key components every 350 operating hours. For example, check the wear of the Special Piston BOMCO F800/1000 CP160 (replace when wear exceeds 1.5mm), inspect the sealing performance of the Brake Device ZJ-30 BG-80 (replace if there is oil leakage), and check the AIR FILTER FOR MUD PUMP RS-3512 for clogging (clean or replace if air flow rate is below 80m³/h).

• Lubrication Maintenance: Apply appropriate lubricating oil to transmission components (such as Thrust Bearing 6839818, S005-3M Bearing Assembly, and Rope Wheel P0300020AA) every 120 operating hours. Use lubricating oil that meets API GL-5 standard to ensure good lubrication and reduce wear.

• Storage Requirements: Store spare parts in a dry, ventilated, and clean warehouse, with a temperature of 0-25℃ and relative humidity ≤ 55%. Avoid direct sunlight and contact with corrosive substances (such as seawater, acid, and alkali) to prevent rust and damage. For electrical parts (such as Switching Power Supply, Aviation Socket) and control components, store them in sealed packaging to avoid moisture and dust.

• Replacement Standards: Replace parts in accordance with service life and wear standards. For example, the service life of the Oil Filter P165877 is 180 operating hours, and it should be replaced in time to ensure oil filtration efficiency; the service life of the Winch Brake Operating Mechanism ZJ70DB KG-80 is 10000 operating hours, and regular inspection and replacement should be carried out to ensure braking safety.
