Stehr - packer SVR


The Stehr packer is the problem solver for different compaction processes.
As more and better compaction results and shorter working hours be required to help the Stehr packer to meet or exceed them such requirements. The packer is a purely mechanical tool, and therefore requires no special hydraulic connections or separate drive system. Attached there is the quick-change equipment or directly to excavators, wheel loaders, tractors, crawler etc.
STEHR packer 

The function:

Stehr compaction wheels using the weight of the carrier, the operating characteristics of the boom and the stick movements to generate the high compression forces. The problem areas in the sewer to manholes, pipe in gusset, on embankments at backfill etc. can be easily compacted to the compressor. The wheel generates an extremely high static compression. So can also be in cohesive soils large bed heights intensively compacted.
With the Stehr packer achieves a high compression performance, ie more compressed m³ at lower cost and better compression.

Typical applications:

STEHR packer STEHR packer
STEHR packer STEHR packer


High point loading per square centimeter produces the desired compaction in different soil types and ratios. Unlike vibrating rollers no water is conveyed through the soil capillaries to the surface. This is the only method for the uniform distribution of moisture in order to achieve uniform compaction.
More safety during the compression process. There is no staff in the trench needed. Optimal compaction of the problem area in addition to the pipe support (gusset).
