In the construction and engineering industry, Hitachi excavators are widely popular for their durability and high performance. With the increase in used excavators on the market, it is particularly important to choose a high-quality used Hitachi excavator. Here are some professional and experience-based suggestions to help you identify a high-quality used Hitachi excavator.
Check the appearance and structure
First, observe the appearance of the excavator. Check whether the machine is evenly painted and whether there is rust, cracks or other obvious damage. These external defects may affect the overall performance of the machine. In addition, check key components such as the bucket, boom and chassis to ensure that there is no excessive wear or deformation.
Check the number of working hours
The use time of the excavator is an important indicator to judge its value and performance. Generally, machines with fewer working hours have more advantages in mechanical condition and maintenance. Generally speaking, the working hours of Hitachi excavators should be within a reasonable range, for example, around 4,000 hours is considered to be more ideal. In the early years, the Japanese replaced their excavators after using them for about 6 years. At that time, the condition of the machines was good. Now it is not the case. The current market is mixed with fakes. We need to focus on an important and core dimension.
Understand the maintenance records
The maintenance records can reflect the maintenance of the machine. If the seller can provide detailed repair and maintenance records, including replacement parts and inspections, it usually means that the machine has been well taken care of. Excavators that are regularly maintained are more guaranteed in terms of performance and life.
Check the hydraulic system
The hydraulic system is the core part of the excavator, and its condition directly affects the working efficiency of the machine. Check the color and cleanliness of the hydraulic oil. Clear hydraulic oil indicates good maintenance. At the same time, start the machine and check whether it is stable during operation, without abnormal noise, and whether the hydraulic system is working properly.
Test operation
Finally, field test operation is an indispensable step. During the test operation, pay attention to whether the various functions of the excavator are operating normally, including the lifting, rotation and walking of the bucket. If the operation is smooth and there is no abnormal noise, it means that the machine is in good condition.
Consult professionals
If you are not familiar with the technical details of the excavator, it is recommended to consult a professional or mechanic. They can provide valuable advice to help you make an informed purchase decision.
