The absolute heavyweight solution
The Stehr Verge Compactor SBV 160-B offers a range of advantages that make it an efficient and environmentally friendly solution for soil compaction. It is the absolute heavyweight solution for professional road and shoulder construction.
While smaller models are designed for standard shoulders, the SBV 160-B (shoulder version of the 160 class) shows its strengths wherever extreme material thicknesses, difficult-to-compact materials, or maximum paving speeds are required.
Key Features & Advantages:
- Enormous centrifugal force: With 160 kN on a single compactor plate, the device offers twice as much point energy as the 80-kN class. This enables extremely high compaction values even with highly compactable building materials, coarse recycled material, or thick dumping heights.
- Maximum depth effect & stability: Shoulders are compacted so firmly down to deeper layers that subsequent breaking off of the asphalt edges by passing trucks or agricultural vehicles is effectively prevented.
- 100 % vertical force transmission: Thanks to the counter-rotating unbalances, the vibration acts exclusively vertically. As a result, the material is pressed firmly downwards instead of yielding or slipping sideways - the formed shoulder edge remains absolutely stable.
- Protection of the asphalt edge & structures: Since no harmful horizontal vibrations occur, there is no cracking or damage to the fresh asphalt surface or to adjacent manhole structures and crash barriers.
- Efficiency in moving traffic: Due to the high compaction performance, the desired degree of compaction is usually achieved in a single, rapid operation. This enormously minimizes construction site times and disruptions to moving traffic.

High fuel & emission savings
Compared to the use of heavy single-drum rollers or complex special equipment, the combination of carrier vehicle and Stehr add-on compactor reduces fuel consumption by up to 50 %.
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 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, and the number of grain contacts and thus the stiffness of the soil increase significantly within a very short time. The natural frequency of the 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 factors such as:
- Fuel savings
- Lower pollutant emissions
- Best CO² balance 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.
