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.

① Bucket cylinder is inverted:

It effectively avoids damage to the piston rod caused by possible collisions during excavation, reduces use risks and saves maintenance costs.

② Increase the volume and weight of the arm:

The digging force is stronger, the operation is easier and the efficiency is higher.

③ The thickness of the arm and ripper decreases:

To reduce excavation resistance, the ripper can be inserted into the working surface as a whole, making the excavation deeper and enabling full bucket loading.

④ The boom integrated head:

The structure is stronger and stronger, effectively reducing the risk of cracking caused by high-intensity operations.

Bubble bag packaging for most products.

Wooden case for little products, like buckets.
Iron frame support for boom arms.

The accessaries and package of excavator long boom arm are subjected to our final confirmation.
