Hydraulic plate compactor for excavators

Hydraulic plate compactor for excavators

Product Introduction

The hydraulic plate compactor is an efficient and versatile excavator attachment designed for compacting various types of soil and gravel. Driven by the excavator’s hydraulic system, it combines the digging function of the excavator with professional compaction capabilities. It is particularly suitable for narrow, sloped, or high-risk areas where traditional large compaction equipment cannot operate, making it an ideal solution for modern construction projects that require enhanced efficiency and quality assurance.

Features and Advantages

1. Exceptional Compaction Performance  
   • High Vibration Force: Delivers greater impact force and amplitude than ordinary plate compactors, enabling deeper and more effective compaction.  
   • High Compaction Density: Allows for thicker filling layers and meets the strict requirements of high-grade foundations, such as those for highways and railways, significantly reducing the number of compaction passes needed.
2. High Efficiency and Flexibility  
   • Quick Attachment System: Easily connected to the excavator via a quick coupler, enabling “one-machine-multi-use.” The same excavator can swiftly switch between digging, backfilling, and compaction tasks, saving time and costs associated with waiting for additional equipment.  
   • Precise Positioning: An optional continuous rotation device allows 360° flexible positioning, making it easy to operate in hard-to-reach areas such as corners, slopes, and trenches, thereby greatly improving productivity.
3. Safe and Eco-Friendly Operation  
   • Low Noise Levels: Operates much more quietly than traditional equipment, making it suitable for noise-sensitive urban areas or nighttime construction, with minimal disturbance to the surrounding environment.  
   • Enhanced Safety: Operators can control the equipment remotely from the cabin, eliminating the need for personnel to enter hazardous areas such as trenches or slopes, significantly reducing on-site risks.
4. Durability and Adaptability  
   • Reliable Core Components: Equipped with imported high-performance hydraulic vibration motors, ensuring robust and long-lasting performance even under harsh working conditions.  
   • Versatile Terrain Application: Powered by the excavator, it requires no additional power source and can adapt to various complex and changing terrains.

Application Scenarios

Pipeline and Utility Projects: Ideal for compacting back fill in pipeline trenches to ensure soil density.  

Road and Railway Construction: Perfect for compacting sub grades, slopes, and abutment backs of highways and railways.  

Building Construction: Used for leveling and compacting building foundations and indoor floors.  

Water Conservancy and Embankment Projects: Suitable for the construction and compaction of riverbanks and canals.  

Confined Space Operations: Irreplaceable for compaction in restricted spaces where large equipment cannot access, such as behind retaining walls, building corners, and utility tunnels.
