In the scorching summer, it is the golden period for construction projects. Facing the challenge of high temperatures, scientific maintenance can ensure that your Amphibious Excavator Applications for Wetland Work remains in good condition. So, how to carry out summer maintenance to ensure the stable operation of the equipment? Haituo Group has some tips for you!

1. Engine System: Preventing overheating is crucial

Coolant inspection and replacement: Ensure that the coolant level is within the standard range. If it is insufficient, add the same type of product promptly to avoid mixing. It is recommended to replace the coolant every 500 hours and clean the dust, fluff, and other debris on the surface of the water tank and radiator to ensure the heat dissipation efficiency.

2. Oil and filter maintenance: High temperatures accelerate the oxidation of the oil. It is recommended to use high-viscosity summer-specific oil and shorten the replacement cycle. At the same time, replace the oil filter to prevent impurities from blocking the oil passage.

II. Hydraulic System: Be Alert to High Temperatures and Contamination

Hydraulic oil management: Regularly check the oil level and quality. If the oil becomes black or contains air bubbles, it must be replaced immediately. Select high-temperature resistant hydraulic oil and ensure that the ventilation holes of the oil tank are unobstructed.

2. Radiator cleaning: The hydraulic oil radiator should be cleaned daily to prevent debris from blocking the cooling effect. If the oil temperature alarm occurs frequently, it is necessary to check whether the cooling fan is operating normally.

III. Electrical System: Waterproof and Free from Short Circuits

Line inspection: Focus on checking whether the battery electrodes are oxidized (using sandpaper for grinding and then applying vaseline), and whether the wiring connector joints are loose. After rain, promptly remove the accumulated water from the control box and relay box.

2. Air conditioning maintenance: Clean the air conditioning filter in the cab, check the refrigerant pressure, and ensure that the operator can work comfortably in high temperatures.

IV. Chassis and Structural Components: Preventing "Fatigue Damage"

Track and supporting wheels: Sand and gravel are prone to getting stuck in the track plates. They should be cleaned after each operation and the tension of the track should be adjusted. High-temperature lubricating grease should be added to the supporting wheels and idler wheels to reduce wear.

2. Prevention of steel structure cracks: At high temperatures, the thermal expansion and contraction of metals intensify. It is necessary to regularly inspect the welded parts such as the boom and bucket arm for any cracks and promptly perform welding repairs.
