Although used construction machinery is relatively inexpensive, its maintenance is crucial. Proper care not only extends the equipment's lifespan but also ensures stable performance and improves efficiency.

Why does used construction machinery require special care?

Long service life: Used equipment experiences extensive wear and tear on its components.

Complex operating environment: Construction machinery operates in harsh environments, which can accelerate its aging process.

Incomplete maintenance records: Some used equipment may have incomplete maintenance records, potentially leading to potential malfunctions.

Key points for maintaining used construction machinery
Detailed inspection:

Appearance inspection: Inspect the equipment for obvious damage, deformation, or rust.
Functional test: Thoroughly test all functions of the equipment to ensure proper operation.
Hydraulic system inspection: Check the hydraulic oil level, oil quality, and leaks.
Lubrication system inspection: Check that all lubrication points are adequately filled with lubricant.
Electrical system inspection: Check for aging wiring and loose connectors.

Regularly Replace Wear Parts:

Filters: Regularly replace engine oil filters, hydraulic oil filters, air filters, etc.

Seals: Regularly inspect and replace aging seals to prevent oil and air leaks.

Wear Parts: Severely worn parts, such as brake pads and clutch plates, should be replaced promptly.

Lubrication and Maintenance:

Lubricant Selection: Select an appropriate lubricant according to the equipment manual.

Lubrication Cycles: Strictly follow lubrication cycles to ensure effective lubrication of all lubrication points.

Coolant Inspection: Regularly check the coolant level and refill promptly.

Radiator Cleaning: Regularly clean the radiator to ensure effective heat dissipation.

Rust Prevention:

Rust-Proofing: Apply rust-proof paint to areas prone to rust.

Keep the equipment dry: Clean the equipment promptly after operation to avoid water accumulation.

Summary
Maintaining used construction machinery is a systematic process that requires long-term commitment. Through careful maintenance, you can extend the life of the equipment, reduce repair costs, and improve work efficiency.
