General Arrangement Drawing
Suitable Working Conditions for Excavator Rock Arms:
Tunneling and Trenching
Excavator rock arms are also used in tunneling and trenching operations, especially when the earth contains layers of rock or
compacted soil. In these environments, the rock arm is invaluable
for breaking rock formations that would otherwise halt progress.
The arm's precision ensures that the excavation is completed
without damaging surrounding structures.
- Key features for tunneling and trenching: Precision in cutting through rock layers, ability to dig at
controlled depths, durable attachments to break rock without
disturbing nearby soil.
- Common use cases: Excavating tunnels for infrastructure projects, digging trenches
for pipelines or cables through rocky soil.
High precision machine of Zhonghe Machinery Manufacturers
Large, floor-mounted double-sided boring and milling lathe:
- Improved Precision and Stability: This machine improves both the precision and the consistency of
the operations.
- Post-Welding Processing: Following welding, the machine bores the entire hole, ensuring the
shaft’s parallelism and verticality.
- Core Functionality: The machine is used mainly for post-welding boring of arms and
buckets, large or small, to guarantee arm accuracy.
- Simultaneous Boring of Both Sides: The double-sided machine bores on both sides at the same time,
ensuring consistent accuracy on both ends.
