The COMPAS compaction analyzing system for Mikasa reversible plate compactors helps contractors improve efficiency and maximize productivity, while avoiding over-compaction. A series of LED lights indicates the progress made with each machine pass. As soil stiffness changes, lights illuminate and inform the operator to either make additional passes or stop because optimum soil conditions have been attained. Mikasa reversible plates feature ergonomically designed handles to minimize the vibration transferred to the operator. Removable extension plates allow the plate to be adapted for various trench applications. COMPAS units are equipped with Yanmar or Subaru diesel engines designed to provide dependable service.
