Many buyers will think that used excavators must have quality problems when purchasing them. Therefore, evaluating the condition of used excavators is a key step to ensure the quality of the purchased equipment. The following aspects can help you fully understand the condition of the excavator:
1.Appearance inspection
First check the appearance of the excavator, including the body, tracks, bucket, etc. Pay attention to whether there is obvious damage, cracks or rust. Appearance problems may reflect the use or maintenance history of the machine.
2.Operation time
Check the total working time of the excavator, which is an important indicator for evaluating the degree of wear of the equipment. Higher working time may mean greater wear and more frequent maintenance.
3.Engine condition
Check the operating condition of the engine, including whether it starts smoothly and whether there is any abnormal noise or smoke. Check the color and cleanliness of the engine oil. Dirty engine oil or foreign matter may indicate engine problems.
4.Hydraulic system
The working condition of the hydraulic system is crucial to the performance of the excavator. Check whether the hydraulic oil is clean and whether there is any leakage in the hydraulic line. When testing the car, pay attention to whether the hydraulic action is smooth, whether there is any vibration, sluggishness, etc.
5.Tracks and chassis
The degree of wear of the track can reflect the use of the excavator. Check the cracks, wear and tightness of the track. The condition of the chassis should also be evaluated. Damage to the chassis may affect the stability of the entire machine.
6.Interior and operating system
Check the interior and operating system of the cab, including the dashboard, joysticks and seats. Make sure all operating systems function properly and the dashboard display is accurate.
8.Maintenance records
Request and review the maintenance records and maintenance history of the equipment. This can help you understand whether the equipment has been regularly maintained and whether there have been major repairs.
9.Test run
Conducting field tests is key to evaluating the condition of the excavator. During the test, observe the working performance of the machine, including the smoothness and responsiveness of the digging, lifting and rotating actions.
