Vibrating Tamping Rammer Hervisa AM 36/3 Rotary with CMP Drive

Hervisa AM 36/3 Rotary is a vibrating tamping rammer engineered for targeted soil compaction in trenches, narrow corridors and confined construction sites. The machine uses a rotary mechanism with a CMP drive to deliver repeated vertical impacts that densify loose and granular soils, improving bearing capacity and reducing risk of future settlement. The design concentrates compaction force at the foot for efficient tamping in tight spaces where larger machinery cannot operate.

Advantages

The rotary tamping mechanism produces consistent impact frequency and amplitude for uniform compaction results. Compact dimensions and a vertical action make the unit easy to position in trenches and around obstacles. Durable construction and an accessible drive assembly support routine maintenance and long service intervals. The focused impact foot reduces lateral disturbance of surrounding soil while increasing depth of compaction compared with hand-operated methods.

Suitable for

• Trench backfilling and pipe bedding
• Small to medium foundation and footing compaction
• Repair works and patching in sidewalks, driveways and pavements
• Confined or narrow site access where plate compactors cannot reach

Key specifications

• Operation mode: vibrating tamping rammer with rotary mechanism
• Drive type: CMP drive providing repeated impact compaction
• Application: vertical impact compaction for loose and granular soils
• Design: compact, handheld/portable unit suitable for trench work
• Typical uses: trench backfill, pipe bedding, small foundation compaction

How to use

Position the rammer so the impact foot sits squarely on the loose material to be compacted. Start the engine per manufacturer instructions and allow the unit to reach operating speed before applying the foot to the soil. Move the machine steadily along the area to be compacted, overlapping passes to ensure uniform density. For trenches, work from the pipe side toward the trench edge, compacting in layers of appropriate thickness and avoiding overloading the unit. Stop the engine before performing adjustments or maintenance and follow standard safety procedures while operating.

Usage recommendations

Use incremental layer compaction: fill and compact in layers consistent with soil type and site specifications. Avoid compacting overly wet soils; for cohesive or highly plastic clays, consider alternative compaction methods. Perform regular inspections of the drive assembly and impact foot for wear, and replace worn components to maintain compaction performance.
