Stehr - Plate Compactors for excavators SBV 60 HF and SBV 120 HF
-
The hexagonal base lets the compactor be positioned anywhere
-
Optimum compaction
-
No extra hydraulic circuit needed on the digger for the rotary drive
-
No complicated rotary motor or oil line
-
Suitable for universal use
Exerting impact forces of 60 to 120 KN at a frequency of 25 or 60 Hz, Stehr attachable compactors have a specially shaped base plate, with no complicated rotary motor or oil line, enabling them to be placed in any position from wherever the carrying vehicle is stationed. The patented Stehr idea to fit these attachable compactors with hexagonal base plates also has the advantage that no extra hydraulic circuit is needed on the digger to drive any rotary motor. Three hydraulic components can thus be avoided, eliminating from the outset any chance of technical defects or leaks.
The shape of the rubber pads and the way they are fitted ensures that vibrations are not relayed to the carrying vehicle but where adjusted properly are transferred into the ground. Test measurements have shown that soil or rubble up to a height of over 1 metre can be completely compacted without any problem. Base plates in different shapes and sizes can be fixed using just four screws, as can a ramming attachment that is also available. As with most Stehr appliances, these are therefore suitable for universal use. Special customer wishes can also be fulfilled in next to no time.
