Laser Tracker & Trackerjack
The laser tracker (Figure 1-7) is an elevation control sensor that
measures and controls the elevation of the screed. After
receiving a signal from a rotating laser, the laser tracker sends a
signal to the Control Box, which then sends a raise or lower
signal to the tow point cylinder.
The Trackerjack attaches to the laser receiver and then mounts
to a vibration pole (Figure 1-7). Use the same cable from the
Sonic Tracker II to power the laser tracker/Trackerjack system.
The laser trackerjack should be removed at the end of each day
and stored in its carrying case.
