The rock arm is also called the burst arm, the eagle beak arm, and the excavator super hook.
The heavy-duty rock arm of the excavator is an excavation and crushing tool designed for processing weathered rock and shale.
Under normal circumstances, the standard-arm ripper cannot work, and the working efficiency of the breaker is relatively low, unable to meet engineering needs and create greater profits. Compared with traditional blasting operations, rock arm operations have high efficiency, low crushing costs, and low maintenance costs
