General Arrangement Drawing
Suitable Working Conditions for Excavator Rock Arms:
Hard-to-Reach or Remote Locations
In remote or hard-to-reach locations, excavator rock arms are particularly useful for breaking rock in
places where larger or traditional equipment cannot operate. The
flexibility of the rock arm, combined with the machine’s ability to
reach high or deep into difficult areas, makes it an ideal solution
for projects in tough-to-access regions, like mountain roads or
densely forested areas.
- Key features for remote locations: Long reach, compact design for maneuverability, reinforced
attachment for heavy-duty performance.
- Common use cases: Excavating in mountainous regions, accessing rocky terrain for
road construction, or extracting rock in isolated areas for energy
projects.
High precision machine of Zhonghe Machinery Manufacturers
Large, floor-standing double-sided boring and milling lathe:
- Precision and Consistency Improvement: The double-sided boring and milling lathe enhances the overall
precision and consistency of the process.
- Post-Welding Processing: Once welding is completed, it bores through the hole, maintaining
parallelism and verticality of the shaft.
- Primary Purpose: It is used mainly for post-welding boring of both small and large
arms and buckets to ensure precision.
- Dual-Sided Boring: The double-sided boring machine performs simultaneous boring on
both sides, ensuring even precision.
