Specialist for the roadside
The Stehr SBV 80 H1 S shoulder compactor offers a range of advantages that make it an efficient and environmentally friendly solution for shoulder compaction. It is specially designed for the efficient compaction of roadsides, shoulders, and narrow hard shoulders.
It combines the proven Stehr compaction technology with maximum flexibility in operation.
Key Features & Advantages:
- Targeted shoulder compaction: Specially developed geometry and guidance to compact shoulders precisely, with dimensional stability, and flush to the asphalt edge without damaging the asphalt.
- High compaction effect: With a centrifugal force of 80 kN, the compact compactor achieves excellent depth effect and high load-bearing capacity for crushed stone, gravel, or earth material in tight spaces.
- 100 % vertical vibration input: Thanks to the patented system of counter-rotating eccentric weights, the vibration energy is directed exclusively vertically into the ground. No lateral shear forces are generated, preventing the shoulder material from slipping and protecting the carrier vehicle.
- Optimal terrain adaptation: The elastic or oscillating suspension allows for smooth tracking along the road profile and slopes.
- Compact & Maneuverable: Due to the compact single-plate design, the device is ideal for narrow carrier vehicles (skid steer loaders, tractors, Unimogs, or excavators) and allows work in moving traffic with minimal space requirements.

Technology
Thanks to 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). Additionally, the plates do not create a rotary movement that loosens the surface again, as is the case with rollers.
The mathematical relationship d ~ 1/ n² applies between the grain size d and its natural frequency n. Higher excitation frequencies increasingly stimulate the smaller grains to vibrate, allowing them to migrate into the free spaces between the larger grains. The number of grain contacts and thus the stiffness of the soil increase significantly within 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, primarily 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 dampened.
The Stehr high-frequency compactor plates operate at a frequency of 70 Hz, to which the smaller diameter grains react under resonance. The effective acceleration of the larger grains is also significantly increased by the improved vibration transmission. With the help of the additional surface pressure exerted by the compactor plate, the material settles more densely. This creates a much more homogeneous surface, and in static plate load tests, the (modulus of elasticity) is always more advantageous 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 carbon footprint with higher performance
Live Demonstration
We present the performance of our plate compactors directly in practice. On our extensive 70,000 m² test site, we not only prove the compaction performance visually through the water glass test, but also document it precisely with state-of-the-art measuring technology - from the dynamic plate load test to vibration measurement according to DIN 4150-3.
