Figure 113: Repositioning the Sonic Tracker
Placement of SAS on Paver
The center connection point of the SAS is the balance point. The position of the balance point to the tow arm
is very critical. By moving the balance point, the performance of the system is greatly affected. The balance
point of the beam should be located 1/ 3 to 2/ 3 the distance from the pivot point of the screed to the tow point
Placing the balance point closer to the 2/ 3 point (near the tow point cylinder), causes the system to have a
slower reaction time. This would be good for smoothness or for mainline paving. Placing the balance point near
the back 1/ 3 (closer to screed) causes the system to have a faster reaction time. This would be good for a
combination of smoothness and joint matching.
