20.500.12556/RUL-129515 An alternative approach to control measurements of crane rails Horizontal and vertical positions of points for the control assessment of crane rails are classically determined separately. The procedure is time consuming and causes non-homogenous accuracy of the horizontal and vertical position of control points. The proposed alternative approach is based on polar measurements using a high accuracy total station instrument and a special platform with two precise surveying prisms fixed on it. Measurements are carried out from a single station thus ensuring a common coordinate system and homogenous accuracy. The position of the characteristic point of a rail is derived from the measured positions of both prisms with known geometry of the platform. The influence of platform non-horizontality is defined, along with its elimination procedure. Accuracy assessment is ensured with redundant measurements. Result of the proposed procedure is a numerical and graphical presentation of characteristic points. The control parameters required in international Eurocode standards are easily determined from them. control measurements crane rails electronic tachymeter "L" platform kontrole meritve žerjavne proge elektronski tahimeter nosilec "L" true false true Angleški jezik Slovenski jezik Članek v reviji 2021-09-03 11:14:36 2021-09-03 11:14:40 2022-09-08 04:08:59 0000-00-00 00:00:00 2012 0 0 Str. 5906-5918 iss. 5 Vol. 12 2012 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 528.53:62 1424-8220 10.3390/s120505906 5823841 RAZ_Marjetic_Ales_2012.pdf RAZ_Marjetic_Ales_2012.pdf 1 2671A99BEFB447EA8A74AF280A38B9AC 472e3f14e061a1a3fd72415d591295725f869db8ae58e09ffb9da84dec07cfab 6b8795fc-0c97-11ec-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=146512 https://www.mdpi.com/1424-8220/12/5/5906 0 60ce8349-0c97-11ec-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=146511 Fakulteta za gradbeništvo in geodezijo 0 0 0
