Description:
1. Rock excavator arm excavator arm with traditional produce different size arm excavator working device because the traditional forward into his arms the whole excavation work, the size of the arm will need to reduce the weight, size, arm in the form of cabinet design. But because the need to move the arm section of rock excavation of rock so you need heavier weight size arm in its cabinets added iron, cement and other major operating wind geological fossils, so called rock arm or shorten the arm, because the shape is very Similar eagle's mouth, also called olecranon arm.
2. Since some geological relatively hard, so rock arm at the same horsepower, the shorter arm, the greater its power. So, when someone asks to buy excavator arm shortened. Such work more energetically. Generally tailored according to customer needs.

Example:
Similar CAT345 excavator rock arm length of 5.3 m boom, arm length of 3.4 meters, with a total weight of up to about 14T, is a good tool for weathered excavation, the current Northwest winds fossil excavation multi such products, compared to traditional blast job in terms of high efficiency, low cost and less environmental pollution.
The characteristics and advantages:
1. Does not change the performance and service life of the original excavators
2. The use of high-strength steel elaborate
3. Which greatly improve the operating range
4. Will work to maximize the efficiency of the excavator
5. According to customer requirements models and design customized
6. Can be used digging machine wife cylinder, pin, tubing and other accessories (reducing customer costs)
The application of rock arm:
Custom models such as PC400-7, PC450-8, PC1100, CAT345B, CAT349, CAT365, ZX450, ZX470, ZX870, DH500, SK450, SK480 excavators and other large custom-size rock type arm, with ripper, specializing in weathered rock, page rock, and various rock, arm in arm size modification rocks all packed inside the box iron sand and cement, more structured, more efficient use of the work, refit good rock arm can reach 17 overall weight tonnage, mountains rock attack easy.
