摘要： Described herein is an earth auger and pole machine for automated installation of poles in earth banks of access roads to open-pit mines. The earth auger and pole machine is fitted with a mechanic boom comprised of a first link and a second link. The first link has an end attached to a base fixed to a conveyor vehicle, and the other end coupled to the second link. The second link comprises a magazine for loading the poles, an auger system to drill the ground, and an installer to place the poles into the hole. This document also describes a method for installing poles in sequence by using the earth auger and pole machine.
