Device and method for conveying thick matter, in particular concrete, with angle of rotation measurement

Abstract

A device for conveying thick matter, in particular concrete, including a thick matter pump; a feed line which leads away from the pump; a boom which receives the feed line and which includes at least one boom arm and which is arranged on a swivel bogie that is preferably provided with a swivel ring, wherein the swivel bogie is rotatable for angular orientation of the boom through a drive, in particular a hydraulic motor with a transmission arranged thereon, wherein the swivel bogie is preferably rotatable through a transmission sprocket acting on the swivel ring of the swivel bogie; and a measuring device which includes rotation angle sensors for measuring the rotation angle of the swivel bogie, wherein the rotation angle of the swivel bogie is measured through direct measurement of a rotation angle of the drive or of the transmission arranged between the motor and swivel bogie.
