that would be difficult or impossible with a standard boom. Long reach booms typically consist of a hydraulic arm with

a dipper stick attached to the end, and they can be used for tasks such as digging deep ditches, digging foundations,

and reaching over obstacles. The length of a long reach boom can range from 15 to 40 meters, depending on the size

of the excavator and the specific requirements of the job.
