Related knowledge about excavator rock arm

[BONOVO]

The rock arm of the excavator is also called the eagle's beak arm, which is named because its appearance and structure are very similar to the "eagle's beak". The rock arm plays a huge role in the excavation of weathered rock engineering projects. Compared with the traditional breaker operation, the rock arm has the obvious advantages of high efficiency, low loss and low maintenance when working with the ripper.

The rock arm belongs to the front-end device of the excavator. It is usually designed, produced and installed by the manufacturer according to the size of the excavator. Therefore, the model of the rock arm of the excavator is customized on demand.

1 Main use

The rock arm of the excavator is also called the eagle's beak arm. It is specially designed for processing weathered rock and shale. Under normal circumstances, the ripper of the standard arm cannot work, and the working efficiency of the breaker is relatively low compared to the ripper, which cannot meet the needs of the project and create greater profits. The work of the rock arm, because the overall arm is shortened and heavier, can greatly increase the excavation force of the excavator and overcome more severe working environments.

2 Design process

1. Design engineers will first use 2D and 3D software to assist in the design of the rock arm, and will use the design system to simulate the actual action of the excavator, so that the designed product can be practical and have good operating performance.

2. Production engineers will carry out stress analysis, material selection, technical and process planning and design work according to the drawings. After completing the above steps, they will start cutting, cutting, welding, grinding and painting, and finally complete the whole set of processes of the rock arm of the excavator.

3 Purchase precautions

1. The working conditions of the excavator are very harsh, so there are quite high requirements for the material of the rock arm of the excavator. Usually regular manufacturers will use high-strength steel new production, and the preferred materials include high strength. Similar steel materials are stable, solid and durable, and have become the manufacturing materials of large-scale engineering machinery;

Rock arm

2. The purchase of the rock arm needs to be customized according to the size of the excavator. At the same time, during the modification of the rock arm, concrete and iron sand will be added to the large and small arms to increase the excavation force of the excavator, which can overcome more severe working environments.
