Operating weight, engine power and bucket volume are the most important three parameters of the used excavator. Used excavator means the excavator has been used and it is a new one.

In the construction machinery industry, it is generally believed that if the using time over 250 hours which records the using time by the computer board in the used excavator.

Such a kind of technology called the remanufacturing engineering machinery. Also this kind of technology is growing quickly in China.

In the transmission system of self-propelled construction machinery, the used excavator is widely used in friction clutch. The working principles of different forms of friction clutch are basic same, which transfers friction torque through the friction surface. The working principle of the friction clutch is using the force of friction between the two friction disks to transfer torque. If want to create friction between the two disks, firstly, must exert pressure force between them to achieve the friction movement of the used Volvo excavators. Clutch can be separated and conjugation, at the same time, transformation between them under what conditions? This is the problem which needs to be solved by the clutch structure of the used excavator.

There are some main source used for the domestic used excavator, such as imported equipment from abroad, domestic joint venture assembly and the natural using of domestic excavator and so on.
