Leica Viva TS11 & TS15 KUMONOS

The remote concrete crack measurement system

Are you still using scaffolds for concrete crack inspections?

Valuable time and huge costs are required for crack inspections of hard-to-reach concrete structures. In a strategic partnership, Leica Geosystems and Kansai Construction Survey Company bring together expertise in measurement and crack monitoring technology. Using the KUMONOS system, cracks can be measured from a distance without the need of expensive scaffolding or elevated work platforms.

The world’s first built-in crack scale
KUMONOS is the world‘s first solution using Leica Viva TS11 & TS15 with a built-in concentric crack scale reticle. Crack widths are calculated from the relation of the distance between the crack and the instrument, and the gauge number that is found by positioning the scale mark over the crack.


Improved measurement accuracy
The KUMONOS system can measure crack widths of 0.3mm, 0.2mm, and 0.1mm from the respective distances of 80 meters, 50 meters and 25 meters. This increase in measurable range allows safe and secure crack inspection in places where scaffolding or a elevated work platform used to be required.

Fast and accurate digital processing for crack inspections

Safe

  • Remote inspection from the ground ensures the safety of the operator.

Accurate

  • Leica Viva TS11 & TS15 KUMONOS records all target points with the accurate and reliable Pin-Point EDM and quadruple axis compensation.

Efficient

  • The KUMONOS office software automatically draws each crack in a CAD drawing.

Economical

  • KUMONOS eliminates the need for expensive scaffolding or elevated work platforms.

1. Aim to the crack and measure a distance (reflectorless).
2. Crack widths are measured one by one by aligning the crack scale with the point of the crack to measure the width.
3. Enter number determined with the crack scale into onboard software – true thickness will be calculated and stored with the collected 3D coordinates of the crack.
4. Export data from instrument to KUMONOS office software.
