Prodem PRB08 Silenced Excavator Hydraulic Hammer
- For 0.7-1.5 ton excavators
- 110J max impact energy
- 750-1300 bpm impact frequency
- 42mm tool diameter
- Compact 75kg operating weight
The Prodem PRB008 is a compact, yet hard-hitting hydraulic hammer purpose-built for small excavators in the 0.7 to 1.5 ton weight class. Weighing in at just 75kg, this attachment delivers an impressive 110 joules of impact at a frequency of 750-1300 blows per minute. It’s the ideal choice for smaller scale demolitions, precise breaking tasks, landscaping applications, and other light-duty jobs where performance and reliability are key.
Optimised for mini excavator hydraulics
With an oil flow of 12-22 l/min and operating pressures of 100-130 bar, this excavator hydraulic hammer is fully compatible with most hydraulic systems on today’s compact excavators. The 42mm tool diameter is optimised for the attachment’s weight class, providing excellent breaking force and speed while allowing you to work efficiently in tight spaces and against walls or foundations.
Low-noise operation
The PRB008 features a fully enclosed housing and cutting edge sound and vibration damping technology. This minimises noise levels while in use, making the hydraulic hammer attachment ideal for urban environments, residential areas, and other areas that may be noise sensitive.
Reliable performance
Prodem's high-quality manufacturing means reliable day-in, day-out performance and reduced maintenance. The PRB008 has 30% fewer components than competing excavator hydraulic hammers in its class - that means less downtime and lower repair costs over the life of the attachment. All wear parts are easily accessed via wide service openings to speed up routine maintenance.
