SharpGrade Laser Grader on PT70 operating with wheels retracted

SharpGrade 2.2DGR Laser Grader fitted to a Terex PT70 operating with the wheels retracted.
Note how much more maneuverable it makes the unit. It is particularly evident when working in a cut area below ground level for rib raft floor preparation.
This allows the sub-grade layers to be quickly and efficiently trimmed to the correct height, level and compacted, ready for the finish layer, including the corners.
Typical accuracy is +/-10mm, especially when trimming in reverse.
Once the finish layer is applied the wheels are lowered and locked in position.
With the wheels lowered the final trim accuracy is typically +/- 3mm. This is due to 3 reasons:
The rigidness of the patented QuadRod linkage, which has zero movement
in the linkage bearings
The outboard cylinders mounted almost directly below the receivers, giving a direct reference between the receivers and cylinders
*More rigid ,pressed steel box structure with double pressing in the lower area, right where the maximum load is taken
This unit is operated by a Leica iCON grader control system that can be upgraded to full3D TPS. We have several operating in 3D TPS
They respond better than a large conventional grader to TPS in variable contours due to the narrower, more rigid blade following the contour easier. The ability to operate forward and reverse and increased maneuverability more than makes up for the narrower blade.
