Description of excavator rock arm rock boom:
The excavator rock arm is specifically designed for penetrating tough rock and compacted soil. Its construction is much sturdier than that of a typical arm or boom, resulting in a heavier weight. At the front, it is fitted with a ripper attachment that has strong teeth, which are highly effective at breaking through challenging materials like dense sand, soil, and rock. This design is especially ideal for demanding excavation projects.
