20140246101 | DEVICE AND METHOD FOR CONVEYING THICK MATTER, IN PARTICULAR CONCRETE, WITH ANGLE OF ROTATION MEASUREMENT - 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. | 09-04-2014 |
20090090687 | Hydraulic Cylinder - In a hydraulic cylinder for a multiple-part mast superstructure comprising at least two mast arms which are connected in an articulated manner and of which one can be pivoted with respect to the other mast arm by the hydraulic cylinder, it is proposed that the base region of the cylinder container is of curved configuration, which cylinder container is closed in the base region on one side in order to accommodate a piston. In this way, the force flux is improved in the walls of the hydraulic cylinder, with the result that manufacturing which uses less material and is correspondingly less expensive is possible, with a simultaneously reduced overall weight. The hydraulic cylinder in accordance with the invention is suitable, in particular, for use with concrete pumps, cranes, lifting platforms and the like or general apparatuses having mast superstructures, in which hydraulic cylinders are used for pivoting. | 04-09-2009 |
20090028633 | ARTICULATED MAST FOR A THICK-MATTER DELIVERY INSTALLATION - 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. | 01-29-2009 |
