Long-Reach Excavator Arm with Heavy-Duty Stone Grab — Optimal Solution for River Embankment & Dam Works

Extend your reach. Improve precision. Move heavier stone—faster and safer

Product description of Excavator Long Arm with Stone Grab:
Built for demanding civil works, our Long-Reach Excavator Arm paired with the Heavy-Duty Stone Grab delivers the reach, strength, and control required for river embankment and dam construction. Engineered as an integrated solution, the long-reach arm provides extended working radius and exceptional stability, while the stone grab offers precise handling of riprap, boulders, gabion stones and other heavy materials. Together they transform challenging waterfront projects into efficient, safer operations.

Key benefits of Excavator Long Arm with Stone Grab:

Extended reach and access: Reach deeper into the channel and across wider embankments without repeatedly repositioning the excavator, reducing setup time and minimizing ground disturbance.
High-capacity handling: Robust jaws and reinforced linkage handle large stones and uneven loads with confidence—ideal for placing riprap and constructing revetments or retaining structures.
Precision placement: Smooth hydraulic control and accurate jaw articulation enable controlled placement of individual stones, improving structural fit and stability of the embankment.
Improved safety and reduced labor: Remove the need for manual stone handling in hazardous areas; operators can work from the cab with clear lines of sight, reducing onsite risk.
Durable in harsh environments: Corrosion-resistant materials, heavy-wear surfaces and sealed pin joints withstand abrasive stone contact and wet conditions typical of river works.
Faster project timelines: Greater reach and reduced ground moves mean fewer interruptions and quicker progress on dam and embankment phases.
