Abstract: A device for conveying thick matter 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, 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, 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.

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.

Abstract: Articulated mast, in particular for concrete delivery installations, comprising at least two mast sections connected to one another by means of a swivel joint and having a straight longitudinal extent, wherein one mast section can be swiveled about a swivel joint axis with respect to the adjacent mast section, such that the articulated mast can be shifted from a folded transport position into a swung-out working position and wherein at least one swivel joint of the articulated mast has an inclined swivel joint axis.

Abstract: The invention relates to a vehicle comprising a pivotable mast arm and frame supports provided on both sides of the vehicle, wherein at least one frame support includes a support element which is extensible into a support position laterally from the vehicle, wherein the vehicle is supported in the support position against tipping through a support base assembly arranged at the support element, wherein the extension of the support element (27) of at least one frame support (4) is provided along at least one slotted link support (35) through a control curve (35a).

Abstract: The invention relates to a device with at least one extension arm or support arm for multi-linked crane shaped extension arms, concrete spreader columns and similar, comprising at least one hydraulic differential cylinder for actuating a support arm. The cylinder comprises a hollow piston rod which has a tubular segment and two end pieces arranged on the ends of said segment, whereby at least one of the end pieces is welded on to the segment thereof. The welded joint is machined and the root of the weld is eliminated. At least one of the end pieces comprises a through opening which enables tool access in order to machine the hollow cavity of the hollow piston rod.
