Wheeled excavators are important mechanical equipment in engineering construction, and their durability is directly related to construction efficiency and cost. To ensure the durability of wheeled excavators, we need to start from multiple key aspects.

1. Correct operation is the basis

1. Smooth start and operation: When starting a wheeled excavator, ensure that it is fully preheated, especially in cold weather. Avoid sudden high throttle start when the machine is cold, which will cause great wear on the engine. After starting, the equipment should be allowed to run at low speed for a few minutes to fully lubricate all parts. During operation, the operation should be smooth, and sudden stops, sudden accelerations and sharp turns should be avoided. For example, during excavation operations, the excavation force should be reasonably controlled according to the hardness of the soil. Excessive force may cause damage to components such as the bucket and shovel teeth, and will also increase the pressure of the hydraulic system. Points such as "smooth operation skills of wheeled excavators" are crucial to ensuring the durability of equipment.

2. Avoid overloaded operations: Operate strictly in accordance with the rated working parameters of the wheeled excavator, and do not overload excavation or hoist heavy objects. Each wheeled excavator has its specified maximum digging force and lifting weight. Overloading will not only cause excessive stress on the structural parts, resulting in deformation or even fracture, but also cause serious damage to core components such as the engine and hydraulic pump. For example, when clearing river silt, you cannot excavate too deep and heavy silt blocks beyond the equipment capacity in order to speed up the progress. You must follow the "Rated Load Specifications for Wheeled Excavators" to ensure that the equipment operates within the safe load range.

2. Daily maintenance is essential

1. Regular inspection and maintenance: formulate a detailed maintenance plan and conduct a comprehensive inspection and maintenance of the wheeled excavator according to the specified time or working hours. Including the replacement of engine oil, hydraulic oil, gear oil, cleaning and replacement of filter elements. For example, engine oil can play a role in lubrication, cooling, cleaning, etc. Regular replacement can ensure the good operation of the internal parts of the engine and extend the service life of the engine. Generally, the engine oil and oil filter element need to be replaced every 500 hours of work, and the air filter element, fuel filter element, etc. are checked at the same time, which meets the requirements of the "regular maintenance cycle of wheeled excavators".

2. Cleaning and tightening of parts: Keep all parts of the wheeled excavator clean, especially the radiator, hydraulic oil tank and other parts. Excessive dust and debris accumulated on the surface of the radiator will affect the heat dissipation effect, causing the engine and hydraulic system oil temperature to be too high, reducing the performance and durability of the equipment. Clean the radiator regularly, and use compressed air to blow away the dust from the inside to the outside. At the same time, check whether the bolts, nuts and other connectors of various parts are loose and tighten them in time. If the connecting bolts of the track plate are loose and not found in time, the track may fall off during the operation, affecting the construction progress and damaging the equipment. Following the "Main Points for Cleaning and Tightening of Wheeled Excavator Parts" can effectively prevent such problems.

3. Reasonable storage and transportation

1. Suitable storage environment: When the wheeled excavator is not used for a long time, choose a suitable storage location. The storage site should be dry and well ventilated to avoid direct sunlight and rain soaking. If stored outdoors, it is best to build a rain shelter. For cold areas in the north, pay attention to cold and warmth during storage in winter. Antifreeze can be added to the engine water tank to prevent the water tank from freezing and cracking. A suitable storage environment meets the "Long-term Storage Requirements for Wheeled Excavators" and can reduce damage to the equipment caused by environmental factors.

2. Safe transportation guarantee: When transporting wheeled excavators, ensure that the transport vehicle has sufficient carrying capacity and is firmly fixed. Use professional transport trailers and adopt appropriate bundling methods to prevent the equipment from displacement and collision during transportation. For example, use high-strength bundling belts to tightly fix the front and rear axles of the wheeled excavator to the trailer, add protective pads to the easily collided parts, and follow the "Safe Transportation Methods for Wheeled Excavators" to avoid damage to equipment parts due to bumps and shaking during transportation.

To ensure the durability of wheeled excavators, strict control is required from all aspects such as operation, maintenance, storage and transportation. Only in this way can the wheeled excavator always maintain a good working condition, extend its service life, and create greater value for engineering construction.
