In general, an excavator refers to a construction machine for transporting, loading, and excavating soil and materials. In addition, attachments are installed on excavators, and work varies depending on the type of attachment installed.

Such excavators work by exchanging two to three attachments per task.

Attachments used in excavators include buckets, tongs, and breakers.

However, since an excavator can usually install only one attachment at a time, in order to use another attachment, the excavator must move to the location where the attachment required for the work is located.

Additionally, there is often a long distance between the location where the necessary attachments are located and the location where the excavator works. Therefore, there is a problem that it takes a lot of time to replace it with the necessary attachment.

In addition, since it takes a lot of time to replace the attachment, there is a problem that the work efficiency of the excavator is reduced.
