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 Crane ZJ-45 Inner Ring Gear Z=44 106.02.30.10-2 for tooth wear (replace if wear exceeds 0.5mm), inspect the Electric Drilling Rig 50DB Disc Brake Solenoid Valve NASS MAGNET PTB-N for response time (replace if response time exceeds 0.05 seconds), and check the High-Pressure Hose 140507021001000000 for cracks (replace if any damage is found).

• Lubrication Maintenance: Apply appropriate lubricating oil to transmission components (such as Crane ZJ-45 Inner Ring Gear, Winch Drive Shaft ZJ45J, and Bushing P1400052AA) 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 Starter 3021038, Insulation Resistance Tester AR3126) and precision instruments, store them in sealed packaging to avoid moisture, dust, and mechanical damage.

• Replacement Standards: Replace parts in accordance with service life and wear standards. For example, the service life of the Machine Filter 1R0739 is 200 operating hours, and it should be replaced in time to ensure oil cleanliness; the service life of the Crane ZJ-45 Inner Ring Gear Z=44 106.02.30.10-2 is 15000 operating hours, and regular inspection and replacement should be carried out to ensure crane transmission stability.
