Production Introduction
The rock arm of the excavator is also called the eagle mouth arm, and the super hook is a sharp tool for excavating and crushing weathered fossils, shale rocks, red sandstone, etc. Compared with the traditional hammer operation, it has the advantages of high efficiency and low loss. Compared with the traditional blasting operation In other words, the operation efficiency is higher, the crushing cost is lower, and the maintenance cost is also very low. Because the overall arm is shortened and the internal filling is heavier, the large and small arms of the 45-ton model can reach 16-17 tons, which can greatly increase the digging force of the excavator and overcome the harsher working environment.Technical Parameters：
