In the construction industry, excavators, as important construction equipment, often need to face a large number of work tasks. With a limited budget, many companies and individuals choose to buy used excavators. Although used excavators are relatively affordable, if you buy them carelessly, you may face problems such as high maintenance costs and short service life. So, how can you ensure that you buy a high-quality used excavator? Japanusedmachinery will introduce you to the five key parts that must be checked when buying a used excavator to help you make a wise choice.
1.Engine status
The engine is the heart of the excavator and determines the power and performance of the entire machine. When buying a used excavator, it is crucial to check the working condition of the engine. First, observe whether the engine has abnormal noise, oil leakage and other problems. Secondly, you can evaluate its use by checking the number of working hours of the engine. Generally speaking, used excavators with lower working hours have less engine wear and a relatively longer service life. In addition, check whether the engine has a maintenance record to ensure that it has not had any major failures.
2.Hydraulic system
The hydraulic system directly affects the operating performance and work efficiency of the excavator. When checking the hydraulic system of used excavator , first observe whether the oil tank and oil pipe have oil leakage, and whether the quality and oil level of the hydraulic oil are normal. Then, start the excavator and operate various hydraulic systems, such as buckets, booms, etc., to observe whether the movements are smooth and responsive. If the hydraulic system is slow or stuck, it may mean that there is a problem inside the system and further inspection and repair are required.
3.Tracks and tires
The tracks and tires are the main parts of the excavator that contact the ground, which directly affect the stability and driving performance of the excavator. When purchasing a used excavator, carefully check the wear of the tracks and tires. The degree of wear of the tracks is not only related to the service life of the excavator, but also closely related to the use environment. If the tracks are severely worn, cracked or deformed, it is necessary to consider replacing them, which increases additional maintenance costs. For tires, it is necessary to check whether the tread is uniform and whether there are obvious cracks or air leaks.
4.Hydraulic cylinders
The hydraulic cylinder is the key to controlling the movement of various parts of the excavator. Any small problem will affect the operating accuracy of the excavator. When checking the hydraulic cylinder, in addition to observing whether there is oil leakage, you should also pay attention to the external wear of the cylinder. Wear or scratches on the cylinder may lead to reduced work efficiency or even more serious failures. Therefore, be sure to check carefully when purchasing to ensure that the cylinder is in good working condition.
5.Electrical system
The electrical system is the “brain” of the excavator and is responsible for controlling the start and stop of various functions. When inspecting a used excavator, pay special attention to the status of the electrical system. First, check whether the battery is charged properly, whether the wire connection is firm, and whether there is aging or corrosion. Secondly, start the excavator and check whether the various function buttons are working properly to ensure that all electrical components can operate stably.
Purchasing used excavation equipment is an important investment decision. Making sure to check the above five key components can effectively reduce the risk of purchase and extend the service life of the equipment. As a buyer, you should not only pay attention to the price, but also pay attention to the quality and performance of the equipment. Choose a reputable supplier and carefully inspect the equipment to ensure that you get the maximum return on your investment.
