Ez tulajdonképpen egy exkavátor típus, amit multibucket excavatornak neveznek, de árokásásra is használják.
In earthwork, the type of machinery used depends on the nature of the soil being worked and the type of work. The machines used include mechanical shovels and multibucket excavators, trench diggers, single-bucket loaders, and hydromechanization equipment (seeEXCAVATING MACHINES). Vibration rollers and static road rollers with metal rolls and pneumatic tires are used to compact earth in embankments and materials in roadbeds.
