Comparison of two different excavator ripper arms

The comparison between the integrated excavator ripper arms and the previous excavator rock arm:

1. On the surface, the old rock arm has one more movement and is more flexible. In actual work, because of the structural limitation of the ripper, the depth is limited when digging the rock with low hardness; when digging the rock with high hardness, the ripper is easy to break. The one-piece excavator ripper arms replaces the forearm and ripper with a whole piece of steel plate. Although part of the flexibility is sacrificed, it completely solves the problem of "soft not dig deep, hard and easy to break".

2. The bucket cylinder of the old rock arm is more of a support. The integrated excavator ripper arms eliminates the bucket cylinder, and connects the tubing of the bucket cylinder to the stick cylinder, which greatly improves the strength and speed of the stick cylinder.

3. In terms of the working principle of the equipment, whether it is a traditional rock arm or an integrated arm, the destructive force of the ripper is increased by increasing its own weight. Simply put, the heavier the weight, the heavier it can hold it. The weight of the old rock boom is mainly concentrated on the big arm, and the weight of the integrated excavator ripper arms is mainly concentrated on the forearm. Most of the weight of the big boom is transmitted to the body through the lifting cylinder, and only the weight of the forearm can be effectively transmitted to the front end. Point of force. In other words, this integrated arm design makes the weight distribution more reasonable to achieve better working results.
