Near-silent operation for urban demolition
This excavator hydraulic hammer features top tier sound suppression technology, featuring a fully enclosed housing, assuring the hammer operates at whisper-quiet levels. This makes Prodem hydraulic hammers perfect for noise-sensitive and residential areas, where noise regulations and community comfort are seen as priorities.
Two moving parts
The PRB050’s two-moving-part design, only the piston and valve, lowers the risk of mechanical failure by reducing the number of components that can wear out or break down. This streamlined design increases reliability and simplifies maintenance resulting in dependability and reduced downtime.
Optimised for maximum productivity
This excavator hammer attachments advanced hydraulic system optimises energy transfer and minimises power loss, providing efficient operation and maximum productivity on heavy-duty projects. By delivering consistent, high-performance power to the tool, the hammer achieves faster cycle times and higher breakout forces, allowing you to tackle demanding tasks with ease and efficiency.
Durable in tough environments
With a full box enclosure crafted from high-strength welded steel, premium heat-treated tool steel, and a hardened rock claw, the PRB050 hydraulic hammer offers wear resistance and long-term durability in even the toughest conditions. These heavy-duty components protect the hammer’s internal parts from damage and guarantee long-lasting performance.
