This 30U small excavator is an efficiency type model, the system is mature and stable, and the leather is resistant to construction. It is widely used in orchard nursery, landscaping, mountain reclamation, farmland reconstruction, indoor demolition and other operations.

Mini excavators can do an amazing job at minimizing some of the more time consuming and labor intensive aspects of residential and light commercial projects.

A mini Excavator with a hammer attachment can literally save hours of hard labor and accomplish the job with ease.
