NPK compactors are designed and built to meet today’s demands for increased productivity on the construction site, and they expand and enhance the versatility of your excavator or backhoe loader. NPK is a leader in trench compaction technology and delivers the industry’s most powerful impact forces as well as superior performance, thanks to a hydraulically driven rotation function.
Powerful vibrations create stress waves in granular or loose materials; this forces air out of the material and compresses the particles more tightly together. The powerful impact works in conjunction with the machine’s downward force to compact cohesive soils, such as clay. The result is faster, safer and more efficient compaction compared with other excavator attachments, as well as manual plate compactors, roller trains, tampers and other machinery. In addition, NPK compactors and rammers offer superior reliability and reduced labour costs.
