Vertical Crawler Expand & Contact Force
The TriTra
x™ 200 expand mechanism is controlled by the Expand Actuator control window.
The expansion mechanism is operated using the
actuator slider in the ICON interface between 8 and 12”
pipe sizes and can go slightly smaller or larger to accommodate
insertion and maintain full contact in 12”
pipe. Contact force is controlled by expanding the mechanism an additional amount after full contact with
the pipe. Springs in the linkage will increase the track pressure as the mechanism expands. The expanded
size and contact force are measured at the vehicle and the Instrument panel can be configured to display
the measurements for the operator in pounds, newtons or kilograms.
Feedback is internally calibrated for the 8 to 12-inch configuration. When using track height extensions,
double the single extension height and add it to the reading. For instance, when using the 2-inch extension
bracket, add 4 inches [100 mm] to the diameter.
Because the springs are pre-compressed, there is a minimum contact force that can be registered by the
sensor and displayed, regardless of whether contact is made. Beyond the minimum force, the springs will
compress allowing true measurement until they bottom out.
