What is a one-piece excavator stump ripper?

As a special attachment of the excavator, the excavator stump ripper is a sharp tool for digging and breaking weathered stone, shale, red sandstone, etc. It has the advantages of high efficiency and low loss compared with traditional breaking hammer operations. Compared with traditional blasting operations In terms of high work efficiency, low crushing cost, and low maintenance cost.

The main structure of the excavator ripper boom is the huge forearm like the eagle beak, so it is also called the eagle beak arm. Compared with ordinary excavators, the boom has been thickened and heavier to cope with stronger impact. The breaking principle of the rock arm is to use the pointed hook at the front end to violently break the rock under the gravity action of the heavy and large arms.

Recently, we have developed an integrated excavator stump ripper. Compared with the traditional rock arm, this integrated design eliminates the bucket cylinder and connects the forearm and the ripper into one, so that the forearm forms an integral arm.

Advantages of one-piece excavator stump ripper:

1. The forearm is cut from a whole piece of high-strength manganese steel, which reduces welding and processing and lowers the cost.

2. The boom is no longer a solid boom, but a hollow reinforced boom, which reduces the weight and reduces the overall performance of the excavator.

3. The innovative design of the integrated excavator stump ripper combines the oil circuits of the bucket cylinder and the stick cylinder into the pipe of the stick cylinder, which increases the overall flow of the stick cylinder and improves the strength and speed of the stick cylinder. It is also increased under certain circumstances without changing the overall hydraulic system of the excavator, resulting in lower loss and greater strength.

4. The plate thickness of the forearm of the integrated rock arm has reached a thickness of 30 cm, which can adapt to more severe working conditions without quality problems and increase the service life of the rock arm.

5. Structures such as ripper and shaft connecting rod are eliminated, maintenance is more trouble-free, the failure rate is also lower, and the driver is more relaxed.
