Compactors / Drivers

Plate Compactors | Compactors / Drivers | Sheet Pile Drivers

NPK's Construction Compactor / Driver equipment is designed and built to meet today's demands for greater jobsite productivity by expanding and enhancing the versatility of your backhoe or excavator.

The leader in trench compaction technology, NPK delivers the industry's greatest impulse forces with overall superior performance through hydraulically operated rotating eccentric action. Greater vibration forces generate stress waves in granular or loose soil material, bringing the air in the soil to the surface thus packing the particles closer together. Greater impulse action works together with the carrier's downward forces to compact cohesive clay-type soils.

Do more work safely a boom's length away

NPK's versatile plate compactors / drivers can work productively virtually anywhere your excavator or backhoe boom can reach: in trenches, over and around pipe, or to the top of piling and sheet pile. It can work next to foundations, around obstructions, and even on steep slopes or rough terrain where conventional rollers and other machines either can't work or would be hazardous to try. In fact, NPK's plate compactors / drivers can keep workers a full boom's length from the compaction or driving action, ensuring workers are away from the danger of cave-ins or equipment contact.

NPK's Plate Compactors / Drivers actually deliver on the promise of greater cost-efficiency and jobsite versatility

These two operating advantages are absolutely required by today's contractors and budget-conscious municipalities.  Utilizing your carrier's hydraulic system, you save on fuel in addition to the need for other costly machines and equipment.  This can be accomplished by using your versatile NPK compactor / driver for:

  • Compacting or driving anywhere a boom can go, and often where a man cannot.
  • Aggregate and soil compaction
  • Trench compaction, as deep as a bucket can dig
  • Steep slope compaction
  • Soil stabilization
  • Waste compaction at waste transfer stations, etc.
  • Breaking up frozen coal, salt and other material
  • Backfilling, including trench backfilling
  • Driving wood, aluminum and steel sheeting, fence posts, guardrail posts, I & H-beams, piling and seawalls, etc.
  • Extracting sheet pile as well as other pilings

Compactor / Driver line includes specialized Sheet Pile Drivers (CSD models)

NPK’s sheet pile drivers use a hydraulically powered clamp bolted to the base of a modified vibratory compactor to drive large diameter pipe or sheeting into soil for foundation support or erosion control.  NPK’s innovative sheet pile driver design combines the high impulse forces of original compaction models with the “gentle touch” vibrations that liquefy the soil to carefully and efficiently press the sheeting being installed into position.  Hydraulic operated jaws, which run on a secondary hydraulic circuit, assist the operator in grasping the sheeting to be driven or extracted, decreasing or eliminating the need for a spotter at the hook up site.  The 180° self-aligning swivel feature minimizes carrier repositioning.  The combination of the hydraulic jaws and the self-aligning swivel feature make operation both safer and easier thus increasing productivity.  The max opening for the clamp jaw opening for all models is 40 mm (1.5”) and as with all boom mounted attachments, sheeting length is limited to excavator reach.
