World first 2015! Stehr SUG 40 Universal Grader

Better planing ... the trick with the Knick ... of course Stehr!

Graders are among the oldest earth-moving machinery. The first graders was built in 1876 Champion in America. This has been a long time with horses and later pulled by crawler tractors. 1921 was supported by the American Rippel Corp. the first motor grader developed. The first motor grader in Europe was 1936 by the company. Fresh out of the year. The function of the middle blade has remained the same. This includes the skew adjustment and tilting on both sides.

138 years it took until Jürgen Stehr, known for his practical developments "Construction tinkerer" from the Hesse Vogelsbergkreis thoughts made about the fact that there's what needs to be better. Its current development is universal graders SUG (Stehr-Universal grader) - a new blade, which serves both as an attachment behind tractors or similar tractors as can also replace the standard crowd on self-propelled graders.

Trigger for the patent-pending new development was the observation of Stehr that at screenings of his new cultivation compressor on wheel loaders at a highway construction site of the leading leveling employed graders firstly was too slow as required for a uniform material deposition material filling before the crowd was not always ensured either excess material runs laterally on the share and remains as burrs are, or it lacks elsewhere. Therefore, for a neat finish work ever more Graders crossings needed - and this costs time! By many move back and forth of the material also takes place a separation and a drying up of the material - this is not possible a subsequent optimum compaction. This effect is quite particularly in forest and field paths, the roof profile is often applied with a trailer on the tractor Graders.

Stehr thereupon his Graderschild just missed a new kinematics, in which an inner tube moves in an outer tube. By moving the sign V-shaped can in all directions both straight, in both directions diagonally, forwards be moved open or closed. So removed material is either collected in the center and centrally taken before the crowd, or it runs immediately on both sides.

 

The pulling of the blade can be adjusted vertically up and down. Once to achieve a straight cut edge, make the cut "sharply" to or to create a roof profile in a single pass. Thus, in a single pass at an incredible speed creates a clean gutter or roof profile, which is required in the country and forestry road construction very much.

But the usual grading go with the Stehr Patent significantly easier and faster - the busy company boss talks about a revolution in the leveling that in some missions up to five times faster results than the traditional lead Assets! Simply because numerous crossings eliminated that cost not only time, but also bring unnecessary operating hours on the counter and therefore cost a lot of fuel, more harmful emissions and enormously more CO² produce.

The specialty of the Stehr-invention is that all known and existing grader with the new crowd can be retrofitted without installing new hydraulic functions. An automatic control is not a problem, even possibly Built can be used.

Then the band positions can be measured by distance sensors in the hydraulic cylinders and shown on a display in the cab. The pulling of the blade can be vertically upwards and adjust downward. Once to achieve a straight cut edge, make the cut "sharply" to or to create a roof profile in a single pass.

The hydraulic cylinders are in 4m crowd on 10 to. Designed tension piston rod side and of course protected by secondary valves. All existing hydraulic cylinders and the known pivot points are used. The 4m wide coulter can be folded for transport position on 2.5 m. After the first screenings before Baupraktikern Stehr was already an enormous interest for its latest development register - grown on a HBM 160 4 TR-grader who was even equipped additionally with the new Stehr-plate compressor SBV 80 3 HC. The first new articulated signs are already mounted on customer machines.
