The Rock Arm has undergone an overall plate thickening treatment. It features an internal filling of high-density adamantine to make it heavier, with a reasonable ratio to produce more digging force.

The enlarged arm cylinder and bucket cylinder can carry greater digging force without malfunctioning. This ensures the arm is ideal for heavy-duty excavation tasks.

The Rock Arm and the ripper adopt a gradual design which is highly effective. The gradual design concentrates all the digging force on the tip of the ripper teeth, and as a result, the crushing effect is better and more effective.

The entire boom arm is post-weld bored, achieving precision comparable to original arms. This ensures superior overall quality of the product.

In the contemporary world of engineering construction, excavators have become indispensable. They are like steel giants that stand on the site with their strong strength and precise operation, helping to complete a variety of complex and arduous tasks. In the excavator family, the excavator rock arm equipped with rock arms stands out for its excellent performance and its wide range of application fields.

The excavator rock arm is an excavator attachment designed for digging hard rock. It is a comprehensively upgraded attachment, in terms of material, structure, and function, that can adapt to a harsh and complex working environment. The rock arm is usually made of high-strength alloy steel, which endows it with high hardness, good toughness, and fatigue resistance when bearing a huge impact. Besides, the surface of the rock arm is subjected to special treatments, which further improve its wear and corrosion resistance, such as sandblasting, shot blasting, or spraying wear-resistant coatings. All these make the rock arm operate efficiently and stably in the face of hard rock for a long time.

The structural design of the rock arm of the excavator also fully considers the special needs of rock excavation. Its long and sturdy arms provide sufficient digging force and depth. The joint part of the rock arm adopts high-strength bearings and precision transmission devices to ensure that various excavation actions can be flexibly and accurately completed under complex and changeable working conditions. Furthermore, the rock arm is equipped with a variety of specifications of bucket teeth and bucket rods to adapt to different rock excavation needs. This makes the rock arm highly flexible and adaptable, enabling it to perform optimally in all types of rock engineering.

The wide application field of the excavator rock arm is one of the critical reasons for it to become a money-making machine. In mining, road construction, water conservancy engineering, tunnel construction, and other fields, the rock arm plays an irreplaceable role. It can not only improve the engineering quality and operation efficiency but also reduce construction costs and risks. That is the reason why excavators equipped with rock arms are favored in the market, becoming the preferred equipment for many construction units and individuals.
