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 and 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 – operating advantages that 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 transfer stations, etc.
- Breaking up frozen coal, salt and other material
- Backfilling, including trench backfilling
- Driving pile, wood, fence posts, guardrail posts, rail and I-beams, piling and seawalls, etc.
- Vinyl, wood, or aluminum sheet pile installation
- Extracting piling and sheet pile
Headlining the list of models is NPK’s C-12C, the largest and most powerful excavator mounted plate compactor / driver available anywhere.
Now available on the C-4C plate compactor is the optional narrow baseplate. This new 18″ x 34″ baseplate allows the operator to get into more restricted spaces. New narrow baseplates are also available as a special order item on the C-6C, C-8C, C-10C and C-12C models.
New in 2017 to the Compactor / Driver line are the specialized Sheet Pile Divers (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 into position. Hydraulic operated jaws, which run on a secondary hydraulic circuit, assist the operator in grasping the material 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.
