General Arrangement Drawing
Suitable Working Conditions for Excavator Rock Arms:
Heavy Earthworks and Excavation Projects
For heavy earthworks, such as the construction of large infrastructure projects (dams,
bridges, highways), excavator rock arms are essential for moving
large amounts of solid rock and breaking through tough ground. The
rock arm allows the excavator to efficiently break and remove solid
rock, providing speed and accuracy in projects that require
large-scale excavation.
- Key features for heavy earthworks: High power to move large volumes of earth, durable design to
handle tough, dense materials.
- Common use cases: Excavating for large infrastructure projects, such as building
bridges, dams, or highways through rocky terrain.
High precision machine of Zhonghe Machinery Manufacturers
Large, floor-standing double-sided boring and milling machine:
- Enhancing Precision and Uniformity: The double-sided boring and milling machine improves the overall
accuracy and consistency of the operations.
- Post-Welding Boring: After welding, the machine bores through the hole to ensure the
parallel and vertical alignment of the shaft.
- Key Role: It is mainly used for post-welding boring of both large and small
arms and buckets, ensuring precision.
- Dual-Side Boring: The double-sided boring machine allows for boring on both sides
simultaneously, ensuring precise accuracy.
