The leader in trench compaction technology

NPK compactors deliver the industry's greatest impulse forces with superior performance through hydraulically-operated rotating eccentric action. Greater vibration forces generate stress waves in loose soil material, bringing the soil's air to the surface and packing particles closer together. This greater impulse action works with the carrier's downward forces to cohesively compact clay-type soils.
Built Tough
NPK compactors are built for the most demanding job sites - they feature rugged welds, heavy-duty direct drive gear motors, durable rubber shock mounts and self-aligning, double row, spherical roller bearings with a heavy-duty roller cage. Rubber shock mounts allow for the isolation of vibration.

Integrated flow control and pressure-relieving valves protect the motor from excessive flow and pressure. Hoses are routed out of the back of the compactor, keeping them safely away from trench walls.
Work safely from a boom's length away
NPK's versatile compactors can work virtually anywhere your excavator or backhoe boom can reach - in trenches, over and around pipe. They can work closely next to foundations, around obstructions, and even on steep slopes or rough terrain. NPK's compactors can keep workers a full boom's length away from the compaction, ensuring they are out of reach from the dangers of cave-ins or equipment compact.
Take your machine to the next level
NPK's construction compactor is designed and built to meet today's demands for increased job site productivity by enhancing the functionality of your machine. The variety of options available allows you to choose the right model for your carrier, regardless of size. NPK's dedicated mounted kits allow compactors to be mounted as:
  • Mini excavator attachments
  • Full-size excavator attachments
  • Backhoe attachments
  • Wheel loader attachments
