What is an excavator rock ripper boom/rock boom?
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. The rock arm is a solid arm, with iron sand filled in the boom and arm. It has a deeper excavation, stronger excavation force, high efficiency and longer service life. It is suitable for working conditions where the rock strength is less than 30 MPa.
Advantages
1. Inverted Bucket Cylinder
Effectively prevents damage to the piston rod from potential impacts during excavation, reducing operational risks and maintenance costs.
2. Enlarged and Weighted Arm
Delivers greater digging force, making operations easier and increasing overall efficiency.
3. Tapered Thickness for Arm and Ripper
Reduces digging resistance and allows the ripper to be fully inserted into the working surface, enabling deeper excavation and ensuring a full bucket load with every pass.
4. Integrated Boom Head
Features a robust, high-strength, one-piece design that effectively minimizes the risk of cracking during heavy-duty operations.
5. Through-Pin Design for Lifting Points
Requires higher manufacturing precision and ensures superior concentricity; this reduces wear, extends service life, and enhances overall durability.
6. Optimized Lift Cylinder Pivot Points
Facilitates faster and more responsive lifting of the boom and arm, thereby boosting operational efficiency.
7. Linkage-Free Design for Arm and Ripper
Eliminates the need for a linkage mechanism, resulting in powerful digging force and the capability to excavate along slopes.
8. Reinforced, Oversized Cylinders
Equipped with a 150mm piston rod for the bucket cylinder and a 140mm piston rod for the arm cylinder, providing higher flow capacity, greater force, and increased power. The bucket cylinder incorporates a built-in protective device to enhance its durability.
Suitable Working Conditions
1. Breaking Hard Rocks:Suitable for granite, basalt, and other hard rocks.Commonly used in mining and quarrying for efficient rock breaking.
2. Handling Weathered Rocks and Shale:Ideal for excavating and breaking weathered rocks and layered shale.
3. Tunneling and Underground Projects:Effective for hard rock excavation in tunnels and underground construction.
4. Foundation and Demolition Work:Used in deep foundation excavation and breaking hard concrete structures.
5. River and Coastal Projects:Excavating hard riverbeds and supporting coastal protection works.
6. High-Intensity, Abrasive Operations:Perfect for tough environments with frequent rock breaking tasks.
Split Rock Boom VS Mono Rock Boom

Split Rock Boom |
Mono Rock Boom |
| In weight |
21-22 Ton |
17.5-19 Ton |
| In appearance |
The split-type dipper arm retains the bucket cylinder and ripper design |
The mono dipper arm and ripper are combined into a single, unified design. |
| In stick cylinder |
The split-type configuration features separate oil supply and return lines for the dipper cylinder |
The mono-type configuration utilizes dual oil supply and return lines, consolidating the oil supply and return circuits for the bucket cylinder into the dipper cylinder. |

ZHONGHE triple quality control system
1.The first system is the technical design drawing review mechanism.
2.The second system is the semi-finished product review mechanism.(each process has a detection testing for the previous process)
3.The third system is the finished product testing.(Before painting, the overall inspection is carried out to check whether the design size matches the welding size, and whether the installation size meets the design requirement.)
To sum up, every single ZHONGHE product has been passed the above three-stage inspection system to ensure that is qualified before shipping.
