General Arrangement Drawing
Suitable Working Conditions for Excavator Rock Arms:
Heavy Rock and Boulders in Waterlogged Areas
Excavator rock arms are effective in waterlogged areas where boulders and heavy rock need to be removed, such as
riverbeds or marshy areas. The strength of the boom, combined with
an appropriate ripper attachment, allows for effective digging and
rock breaking in muddy or water-saturated soils. This is
particularly useful in river excavation or clearing waterlogged
land for construction projects.
- Key features for waterlogged areas: Hydraulic systems designed for underwater use, rust-resistant
components.
- Common use cases: Riverbed excavation, removing boulders from marshy or flooded
land, dredging operations.
High precision machine of Zhonghe Machinery Manufacturers
Large, floor-mounted double-sided boring and milling lathe:
- Improved Operational Precision and Consistency: This machine enhances both the precision and consistency of the
operations.
- Post-Welding Process: After welding is finished, it bores the hole to ensure the shaft’s
parallelism and verticality.
- Main Usage: The machine is primarily responsible for post-welding boring of
large and small arms and buckets to ensure the accuracy of the arm.
- Dual-Side Boring: The double-sided boring lathe performs boring on both sides
simultaneously, ensuring consistent precision.
