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
