Sažetak
During the past 35 year period of a rotary kiln work at the cement factory "Cemex" in Kaštel Sućurac, Croatia, its central support has been damaged. This caused increased horizontal displacements. Furthermore, as a result of a rotary kiln work, vibrations were transmitted to the ground in the vicinity of the support, which made the use of LVDT (Linear Variable Differential Transformer) sensors for displacement measurements questionable. For this reason, dynamic displacements of the rotary kiln support were planned to be measured by additional method using Robotic Total Station (RTS). RTS could be set up outside the area of vibration caused by the work of the rotary kiln, but the problems for its usage were the values of the expected displacements that were in the range of a few tenths of a millimetre. For this reason, prior to the measurements, it was necessary to test whether it was possible to determine submillimetre dynamic displacements using RTS. Tests were conducted in the Laboratory of Civil Engineering at the University of Zagreb and were simulated by using a universal (static- dynamic) testing machine. The results of RTS testing from the laboratory, as well as the comparison of determined displacements of the rotary kiln support measured by RTS and LVDT sensors will be presented in the paper.
