Maintenance of Wheeled Excavators

Every morning, the entire vehicle should be filled with fuel, the fuel tank emptied, and the drain valve should be opened to release any water. Regular checks of oil levels and coolant are essential. Premature wear of the fuel system components (fuel pump, nozzles) is often a result of improper daily maintenance by the operators. The machine can be equipped with air blowers for air filtration and radiator cooling. Maintenance tasks should be completed on schedule and in batches. In harsh working conditions (frequent use of breakers, dusty environments), the maintenance cycle may need to be shortened.

Importantly, keeping the wheeled excavator well-maintained can prevent major repairs and oil leaks in the engine, pumps, and valves, even after 10,000 hours of operation. It is necessary for operators to remove their shoes when entering the cabin. This practice helps keep the cabin clean, prevents damage to the air conditioning filter, and reduces the harm caused by dusty air circulation to the operator's health.

Using a Wheeled Excavator:

  1. Smooth Operation on Slopes: When performing leveling operations, place the machine on level ground to prevent excessive body movement. The coordination between the boom and stick movements is crucial for effective leveling.

  2. Loading Operations: Position the machine on stable ground to facilitate accurate rotation during unloading, reducing cycle time. Maintain an appropriate distance between the machine and the truck to prevent collisions during 180-degree turns. Optimize visibility by correctly adjusting the rotation angle to minimize turning time. Place the truck lower than the excavator to shorten the boom's ascent time and ensure clear visibility. Prioritize loading sand and crushed stone before placing large rocks to minimize impact on the truck.

  3. Soft or Waterlogged Areas: In soft soil areas, be aware of soil compactness and limit the excavator's digging range to prevent accidents such as landslides and deep body sinking. In waterlogged conditions, consider the machine's allowable water depth (water level should be below the center of the supporting rollers). Avoid operating in high water levels to prevent inadequate lubrication in the swing bearing and damage to engine fan blades due to water ingress, leading to circuit short-circuits or damage.

  4. Lifting Operations: When using the hydraulic excavator for lifting operations, ensure the surrounding area is safe and use high-strength hooks and wire ropes. Utilize specialized lifting devices when possible. Choose the micro-operation mode for precise and balanced movements. Use appropriate rope lengths to prevent excessive swinging of the lifted object, ensuring accurate control. Adjust the bucket position correctly to avoid rope slippage. Operators should avoid getting close to lifted objects to minimize the risk of accidents due to improper handling.

  5. Smooth Operation: Stability during work not only improves work efficiency and extends machine life but also ensures safe operation. Keep the machine on a flat surface whenever possible.
