How to conduct a thorough inspection of the excavator?

As a heavy construction machinery, excavator plays an important role in earthmoving engineering, mining, road construction and other fields. A thorough inspection of an excavator is a key step in ensuring its normal operation, extending its service life and ensuring operator safety. Here are the specific steps for conducting a thorough inspection of an excavator:

1.Visual inspection

Check the body, such as the used Doosan excavator to check the body for obvious deformation, damage or corrosion. At the same time, pay attention to observe whether there are oil leaks or obvious leakage traces around the fuselage. Check the tires, and for crawler excavators, check the wear of the track plate and the condition of the track sprocket to ensure that there is no loosening or excessive wear.

2.Engine check

Check for odors, before starting the engine, first detect if there is an abnormal odor, such as burning smell may indicate overheating problems. Check the liquid level, including oil, coolant and fuel, etc., to ensure that the liquid level of various liquids is within the normal range, and timely add or replace insufficient or deteriorated liquids. Check the air filter element to ensure that the air filter is clean and non-clogged to avoid affecting the engine performance.

3.Hydraulic system inspection

Check the oil quality, regularly check the quality and level of hydraulic oil, to ensure that the oil is clean and not expired. Contamination or aging of hydraulic oil will seriously affect system performance. Pipeline inspection, check all hydraulic lines for leaks, hoses are cracked or aging. Pump valve check, check the working status of hydraulic pump and valve, listen to whether there is an abnormal sound, confirm whether the pressure gauge reading is normal.

4.Electrical system inspection

Check the battery to make sure it is fully charged and the wires are well connected without corrosion or breakage. For electrical equipment, check that the starter, generator and all indicator lights are working properly.

5.Check the steering brake system

Steering systems, test the response speed and flexibility of used Kobelco steering systems to ensure no delays or stalling. Brake system, check the braking effect of the brake system to ensure that it can stop quickly in an emergency.

To sum up, a thorough inspection of the excavator should cover a full range of inspections from the appearance to the engine, hydraulic system and electrical system. Through such comprehensive evaluation, the performance and operation safety of the excavator can be ensured to the greatest extent.
