Um guia para avaliar a condição de uma escavadeira usada

Many buyers assume that there must be quality issues with used excavators when purchasing them. Therefore, evaluating the condition of a used excavator is a key step in ensuring the quality of the equipment purchased. Next, we will help you fully understand the condition of the excavator from the following aspects:

1.Appearance inspection

First, check the appearance of the excavator, including the body, tracks, bucket, etc. Pay attention to whether there are obvious damage, cracks or rust. Appearance problems may reflect the use or maintenance history of the machine.

2.Running 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 hours 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 oil or foreign matter may indicate a problem with the engine.

4.Hydraulic system

The working condition of the hydraulic system is critical to the performance of the excavator. Check whether the hydraulic oil is clean and whether there are leaks in the hydraulic lines. During the test run, pay attention to whether the hydraulic action is smooth, whether there is vibration, sluggishness, etc.

5.Tracks and chassis

The wear of the tracks can reflect the use of the excavator. Check the tracks for cracks, wear, and tightness. The condition of the chassis should also be evaluated. Chassis damage may affect the stability of the entire machine.

6.Interior and operating system

Check the interior of the cab and the operating system, including the dashboard, joysticks, and seats. Make sure that all operating systems are operating properly and the dashboard display is accurate.

7.Maintenance records

Request and review the maintenance records and maintenance history of used construction equipment. This can help you understand whether the equipment is regularly maintained and whether it has been overhauled.

8.Trial 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.
