Compaction & Drilling Attachments
Hydraulic Plate Compactor
Vibrating plate mounted on the dipper for compacting trench backfill, embankments and slopes from outside the excavation. Keeps crews out of unsupported trenches.
Features
- Eccentric-driven plate producing vibration at a frequency suited to granular backfill.
- Plate size and centrifugal force matched so contact pressure suits the layer being compacted.
- Rubber shock mounts isolating vibration from the carrier's boom and pins.
- Works on slopes and batters that a walk-behind plate cannot safely reach.
- Also used for driving sheet piling and trench sheets on smaller sections.
Specifications
| Figure | Typical range | Unit | Why it matters |
|---|---|---|---|
| Carrier operating weight range | 1.5 - 30 | t | Plate size is matched to carrier reach and mass |
| Centrifugal force | 20 - 120 | kN | Compaction energy into the layer |
| Vibration frequency | 33 - 45 | Hz | Effectiveness varies with soil type |
| Plate dimensions | 400 x 500 - 1 200 x 1 500 | mm | Sets contact pressure and trench coverage |
| Required oil flow | 30 - 140 | l/min | Determines achieved frequency |
| Attachment mass | 120 - 1 800 | kg | Static load adds to the compaction effect |
