How to properly operate and maintain an excavator in order to maximize its useful life

Machines, like people, have a life cycle that includes stages such as birth, childhood, adolescence, middle age, old age, and extinction, and each stage necessitates the provision of appropriate care

Machines, like people, have a life cycle that includes stages such as birth, childhood, adolescence, middle age, old age, and extinction, and each stage necessitates the provision of appropriate care. Although the excavator is a piece of heavy machinery made of steel and iron, it also has its delicate moments. If we do not pay attention to maintenance at all critical stages, the high maintenance costs in the future will be extremely distressing. As a result, it is critical to understand when and what to do in order to extend the life of your excavator.

An excavator has a life from the moment it is driven out of the manufacturing workshop, which is also the beginning of its life. At this point, we should concentrate on getting the new machine up and running. This is referred to as the running in period. A very interesting phenomenon occurs frequently when people purchase a car, particularly a personal vehicle: when it comes to the use of the new vehicle during the break-in period, people are often extremely concerned. They are not allowed to drive fast or far. They are constantly concerned that poor running in of the vehicle during the running in period will have an adverse effect on future performance, but they are unable to obtain the same level of attention for the excavator.


In reality, when it comes to the best mini excavator that was recently purchased back, the first thing that comes to mind is how to maximize the opportunity to make money. Because it is a new machine, it should not be subjected to excessive use. In any case, a warranty period is in effect. As a result, the machine is frequently overloaded, resulting in a high rate of early failures. The service life of the machine is significantly reduced when there is a lot of heart blocking. However, the fact remains that the parts and components of the new machine have only recently been assembled, and the surface is rough. In operation, the machine's concave and convex parts rub against one another, and the rubbed metal debris contributes to the continuous friction. As a result, the parts and components from this time period are easily damaged. Overloading operations at this time can easily result in damage to the parts and premature failure.

As a result, for the newly purchased excavator, first and foremost, ensure that the appropriate operation volume is maintained, that the operation is not overloaded, and that the working load during the running in period does not exceed 60% of the rated working load in order to avoid overheating caused by continuous operation of the machine for an extended period of time. Furthermore, do not operate a motor vehicle while riding the bus. Examine the instrument panel, the oil, and the tightness of the screws. Every shift, lubricate the lubrication points. Remember, it will only work optimally for you if you are kind to it.

How should an excavator be properly maintained?

The excavator's youth is also the stage in which the machine plays the most important role. Despite the fact that all parts have been taken out of service for a period of time and that the lubrication coordination has been established, the workload cannot be increased without causing disruption. It is preferable to have a routine maintenance schedule.

Check for oil, water, and gas leaks, as well as overheating of parts, on a daily basis. Check the levels of the diesel engine oil, coolant, and hydraulic oil;Examine the tire pressure and wear;Check all of the instruments and lights. Each hinge rock breaker for mini excavator joint should be greased.

Weekly maintenance includes changing the transmission oil and cleaning the screen in the oil pan filter;Change the oil in the engine;Check the battery's liquid level and clean the battery connector with vaseline. Check the tightness of the rim, brake disc, and axle bolts. Check that each fastening bolt is securely fastened. Ensure that the oil levels in the front and rear axles are adequate. Clean the air filter (and, if necessary, replace the filter element);Engine oil, diesel oil, and transmission oil filters should all be changed regularly. Check to see if the welds on the working device, as well as the front and rear frames, are cracked.

Replace the gear oil in the front and rear axles on a monthly basis. Remove the oil suction screen from the diesel tank and clean it;Remove any pollutants that have accumulated on the surface of the water tank or radiator;Change the engine oil, as well as the engine oil and diesel oil filter. Oil and filter should be changed on your transmission. Check the clearance between the engine's valves. Check the engine's operation;Check the hydraulic system to see if it is in good working order. Examine the performance of the steering system; andCheck the brake system's performance and replace the brake oil if necessary.

How can I increase the service life of my excavator?

The excavator has a depreciation life of ten years, but after 5000 hours of operation, various problems will begin to manifest themselves. As a result, in addition to routine maintenance in the young and middle-aged, pay close attention to the method of extending the service life after 5000 hours. So, what methods are available to extend the service life of an excavator?

1: Properly use the excavator, strictly adhere to the safety technical operation procedures, implement target cost management for mechanical equipment, link the economic benefits of the operator with the use fees of the excavator (such as fuel and oil fees, maintenance fees, material fees, tool fees, and so on), and convert the passive daily maintenance equipment of the excavator driver into active daily maintenance equipment


2:Reduce the invisible wear on the excavator caused by the environment's climate, that is, reduce the impact of environmental factors on the excavator's service life. Because most construction machinery is operated in the open air and the operation site changes frequently, the temperature, environment, climate, and other factors of the operation site have a significant impact on its performance. It is necessary to provide a parking area (shed) for long-term fixed operation machinery, or to implement maintenance measures such as covering the upper part with wood and supporting the lower part with wood to reduce the invisible wear caused by the sun, rain, and corrosion. Many construction companies do not consider the impact of environmental factors on the operation of machinery (for example, if the ambient temperature is too low, it will have disastrous consequences for the operation of the machinery. It has been proven that failure to implement appropriate protective or adaptive measures has resulted in decreased mechanical performance as well as shorter service life and even accidents.

3:The key to extending the service life of an excavator log grapple is to perform routine maintenance on it. The Ministry of Communications' maintenance regulations for road construction and maintenance machinery clearly outline the requirements for loaders. However, when the construction period is short and the workload is heavy, many construction units tend to overlook the maintenance work, believing that the machinery is in good working order and does not require stopping for maintenance. This will effectively eliminate the hidden threat of mechanical accidents in the future. Because maintenance can eliminate mechanical hidden dangers, if it is not performed on a timely basis, it will frequently result in major faults in mechanical equipment, as well as personal injury and accidents, to name a few. This not only raises the cost of maintenance, but it also causes the construction period to be extended.

4:Incorporate advanced mechanical inspection and other auxiliary maintenance methods. Mechanical maintenance is a critical link in the chain of extending the service life of machinery. Adoption of reasonable maintenance procedures can significantly increase the service life of construction equipment. According to relevant statistics, the use of advanced condition monitoring systems can reduce the cost of maintenance by 25% to 50%, reduce the failure rate by 75%, and extend the service life of the machinery.
