Laser Grade Checking System
Once the Sonic Stringline has been set, the operator can dial in the
desired cross slope and depth of cut and begin grading. As he begins
grading, the grade must be immediately inspected to verify the cut is
correct. The grade setters job is now to inspect the grade behind the
grader and make adjustments if necessary.
Although this can be done by various methods, the Laser Grade
Checking System is a quick, accurate, one person grade checking
tool. It allows grade to be inspected not just at the edge of the road,
but all the way across the section at any desired distance.
Set the laser on the Stringline Laser Bracket and place the bracket on
the Sonic Grade Clip. The automatic leveling laser will produce a
"stringline" of laser light across the road at the same height as the
stringline.
