  • Stick Mounted Static & Vibratory Compaction Wheels

    Stick Mounted Static & Vibratory Compaction Wheels. MBW static compaction wheels are built to standards suitable for vibratory compactors. That means heavier bearings (to 1,100,000 lbs. static load), heavier shafts (to 710,000 lbs. shear strength) with a correspondingly heavy frame that supports the wheel at both ends to minimize frame and shaft deformation.

  • Vibro Compaction | Hayward Baker

    During vibro compaction, clean sand backfill is typically added at the ground surface to compensate for the decrease in soil volume from the densification process. The vibratory energy reduces the inter-granular forces between the soil particles, allowing them to move into a denser configuration, typically reaching a relative density of 70 to 85%.
