Prevent Heatstroke and Keep Your Excavator Healthy in the Hot Summer

As the summer heat sets in, it's crucial to take proactive measures to ensure the proper functioning of your excavator's cooling system and prevent heat-related issues. In this blog post, we will provide you with valuable tips to keep your excavator in optimal condition during the scorching summer months.

 

1. Thoroughly Clean and Maintain the Cooling System:

Before summer arrives, it's essential to clean, tighten, and lubricate all parts of the cooling system. Clear any scale or debris from the radiator and cooling system to enhance heat dissipation and promote efficient water circulation.

 

2. Check Drive Belt and Fan:

Regularly inspect the drive belt of the water pump and fan. Over time, belts can become fatigued and deformed, leading to decreased cooling efficiency. Replace worn-out belts with the correct type and length, and ensure they are properly tensioned.

 

3. Inspect Water Tank Hose:

Check the hose connecting the water tank for cracks and signs of water leakage. These hoses are prone to early damage, which can hinder proper water supply and cause the engine temperature to rise. Promptly repair or replace damaged hoses and maintain an adequate level of cooling water.

 

4. Monitor Water Temperature Gauge:

Stay vigilant about monitoring the water temperature gauge. If the gauge reaches above 90°, take immediate action. Park the excavator in a shaded area and allow it to cool down at idle speed. Avoid turning off the engine immediately to prevent engine damage. Additionally, check the tension of the fan belt once the temperature drops.

 

5. Perform Lubrication SystemTest:

Conduct a comprehensive performance test on the excavator's lubrication system. Ensure that the oil pressure gauge and gearbox pressure gauge indicate accurately. Inspect the quality and quantity of oil in the gearbox, pitch changer, and drive axle, maintaining cleanliness and optimal levels.

 

6. Monitor Tire Temperature and Pressure:

Small loader tires typically have around 14 layers, which transfer heat faster and are more prone to overheating. Increased tire temperature can lead to higher internal pressure and reduced rubber properties, potentially causing a blowout. If tire pressure and temperature are excessive, park the excavator in a cool area for cooling before continuing. Avoid deflating tires or pouring cold water on hot tires.

 

7. Regularly Check Brake Efficiency:

Frequently check the braking efficiency of the excavator to detect and address any braking system faults promptly. Prolonged operation can cause excessive heat in the brake hub and brake pad, leading to decreased performance. Immediately stop the machine and allow it to cool down to prevent safety risks. Do not pour cold water on the brakes.

 

8. Maintain Battery Electrolyte Level:

High temperatures in summer cause rapid evaporation of the battery electrolyte. Ensure the electrolyte level is maintained by replenishing with distilled water or electrolyte as needed. Keep the battery surface clean, including the pole posts and wire connectors. Maintain unobstructed vent holes and securely fix the battery. Address any battery failures promptly through timely maintenance.

 

9. Driver Rest and Safety:

Summer driving can be physically demanding, leading to driver fatigue. Take regular breaks and ensure you get enough rest to maintain energy and productivity. Prioritize driver well-being for safer and more efficient work.

 

10. Handling Water Wading:

In case of water wading, drive the excavator at a low speed afterwards. The heat generated by friction between the brake shoe and brake hub will help dry the shoe and prevent braking failure. Exercise caution and remain vigilant.

 

11. Choose Quality Lubricating Oil:

Under high temperatures, the lubrication and wear of the transmission system depend on the quality of the lubricating oil used. Opt for oil with a high degree of stickiness to reduce system wear. Be diligent in preventing water and air from entering the hydraulic system to avoid corrosion and wear.

 

As the summer season arrives, taking preventive measures to protect your excavator from heat-related issues is vital. By following these tips and maintaining a safe and healthy operating environment, you can ensure that your excavator performs optimally throughout the hot summer months. Stay cool and stay safe!
