The different names represent newer
software versions and upgrades
There are many other manufacturers
that have similar styles of systems
Robotic – Electro-Mechanical
Communication to computer via
Bluetooth
Laser scanner emits 2
laser beams to
triangulate position of
targets; then fed to
computer software
Shark probes emit an ultrasonic sound
that is received by microphones in the
beam to locate position
Measuring Systems
•
Detect Misalignment
•
Monitor Repair Process
•
Verify the Repair
The main focus of the technician is
the amount of deviation from
factory specification
Unibody tolerance – 3mm or less
BOF tolerance - 5mm or less
Car 0 Liner sheet shows Right and Left specs for
each side
Points that are measured show
deviation from factory specification
Display allows quick analysis of diamond (Length)
or twist (Ht) and direction of other areas of damage
Point R5 has:
9mm of Mash
15mm of inward Sidesway
5mm of Sag/Kickup
