Efficient & Compact
The Stehr plate compactor SBV 80 HC 2 offers a range of advantages that make it an efficient and environmentally friendly solution for soil compaction.
The SBV 80 HC 2 was developed specifically for tight inner-city construction sites. Despite its compact overall width of just 1,400 mm, it achieves compaction results in granular media that even a 13-ton single-drum roller cannot match.
The crucial advantage: The combination of loader and compactor can easily be transported on a car tandem trailer. This saves on cost-intensive low-loader transport and avoids expensive empty runs.

More performance, fewer emissions
Our system sets new standards in compaction technology. Thanks to minimal environmental vibrations and noticeably faster construction progress, you maximize your productivity. At the same time, you benefit from an outstanding CO² footprint, significant fuel savings, and optimal utilization of your carrier machine.
Technology
Through the patented 4-shaft technology with a 70 Hz vibration frequency, the material to be compacted is excited twice as fast as with single-drum rollers (max. 35 Hz), and the plates prevent any rotary movement that would loosen the surface again, as happens with rollers.
Between the grain size d and its natural frequency n, the mathematical relationship d ~ 1/n² applies. Higher excitation frequencies increasingly stimulate the smaller grains to vibrate, allowing them to migrate into the free spaces between the larger grains. This rapidly increases the number of grain contacts and thus the stiffness of the soil in a very short time. The natural frequency of soils is usually between 25 and 35 Hz and changes as compaction progresses.
If this frequency is introduced into the soil, predominantly the grains with a larger diameter are stimulated to vibrate, while all other grain sizes react only slightly due to the relatively low acceleration. Since the larger grains are always surrounded by smaller grains, the acceleration of the large grains is damped.
The Stehr high-frequency compactor plates operate at a frequency of 70 Hz, to which the grains with a smaller diameter react in resonance. The effective acceleration of the larger grains is also significantly amplified by the improved vibration transmission. With the help of the additional surface pressure exerted by the compactor plate, the material is embedded more densely. This creates a much more homogeneous surface, and in static plate load tests, the (elastic modulus) is always more favorable due to the closed surface.
CO² - Fuel - Performance
The use of the compactor plates also results in sustainable environmental benefits such as:
- Fuel savings
- Lower pollutant emissions
- Best CO² footprint with higher performance
Live Demonstration
We present the performance of our plate compactors directly in practice. On our expansive 70,000 m² test site, we verify the compaction performance not only visually through the water glass test but also prove it precisely with state-of-the-art measuring technology – from the dynamic plate load test to vibration measurement in accordance with DIN 4150-3.
