Construction Compactor, Construction Driver

NPK Construction Compactor and Construction Driver equipment is designed and built to meet today's demands for greater jobsite productivity, 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 soil's air 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 Construction Compactor and Construction Driver can work productively virtually anywhere your excavator or backhoe boom can reach. In trenches, over and around pipe, to the top of piling and sheeting. Next to foundations and around obstructions. 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 Construction Compactor and Construction Driver can keep workers a full boom's length from the compaction or driving action, away from the danger of cave-ins or equipment contact.

Select the NPK Construction Compactor or Construction Driver that's right for your application.

NPK's full selection of Construction Compactor and Constructor Driver equipment gives you the exact power you need for your jobs and jobsite conditions. The right model for carriers ranging from the smallest mini-excavators and backhoe/loaders to the larger excavators.

Headlining the list of models is NPK's C-12C, largest and most powerful boom mounted plate Construction Compactor and Construction Driver available anywhere.

Now available on the new C-4C model Compactor / Driver is the optional narrow baseplate. This new 18 x 34 inch baseplate allows the operator to get into even 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.

NPK Construction Compactor and Construction Driver 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.
