Product Features

  • The implementation of innovative contactless technology on the 6620E roller significantly extends the service life of vibratory bearings, directly contributing to increased operational efficiency and reduced maintenance costs. It features a sophisticated dual-frequency vibration system with dual amplitude, allowing precise adjustment of compaction force for various substrates and working conditions, achieving optimal soil density with minimal execution time;
  • Larger diameter drums, combined with consistent and uniform vibration amplitude, ensure evenly distributed centrifugal compaction force, eliminating the need for multiple passes and significantly increasing on-site productivity. This model sets new standards in compaction performance with its power, reliability, and durability;
  • The operator’s cabin is designed with special attention to ergonomics and safety, offering optimal visibility and reducing noise and vibration levels during operation. Advanced control systems and automatic performance management ensure stable and precise operation in all conditions, while fuel-efficient engines and economy systems contribute to cost-effectiveness and environmental friendliness;
  • A top-tier solution for a wide range of construction and infrastructure projects, it offers the perfect combination of high power, long service life, and minimal operating costs, making it a reliable partner for every professional contractor.
