5.10.2. Low Profile Probe Holder Frame - Flat or Circumferential Only
The low profile frame adds weld scanning capability to the
NAVIC
motorized scanner.
This frame can utilize
(4)
slip joint probe holders
(2 Phased Array and 2 TOFD, typically)
.
The low profile design of this frame allows for scanning on diameters where radial
clearance is limited.
WARNING!
FALLING OBJECT HAZARD.
When the Probe Holder Frame is mounted in both
the left hand and right hand swivel mounts, operation
must be limited to driving in the circumferential
direction. Only very slight corrective steering is
permitted. Excessive steering may cause the crawler
to fall and
SEVERE INJURY
or
DEATH
could result.
