Hydraulic Compactor is an excavator attachment used to compact soil and backfill through a vibrating plate. It is especially useful in trenches, around foundations, on slopes and in confined work areas where conventional walk-behind or ride-on compaction equipment may have limited access.

Typical applications include utility backfill, road repair and civil construction. Selection should be based on carrier size, material type, required working area, hydraulic compatibility, mounting interface and the compaction method specified for the project.
