Patent number: 11732488Abstract: A vehicle having a thick matter pump has multiple supporting devices, a rotatable mast assembly with part-mast members, and a hydraulic drive assembly with hydraulic drives for the supporting devices and the mast assembly. A valve assembly is provided for the hydraulic drive assembly. The valve assembly has a group of proportional valves and a group of switching valve devices which are each connected to at least one hydraulic drive of the supporting devices or the part-mast members. The switching valve devices are connected downstream of the proportional valves. Exactly one switching valve device is supplied by exactly one proportional valve and is connected downstream of exactly one proportional valve such that outputs of the proportional valves lead exclusively to inputs of the switching valve devices.Type: GrantFiled: January 29, 2020Date of Patent: August 22, 2023Assignee: Putzmeister Engineering GmbHInventors: Martin Diebold, Jan-Martin Veit

Patent number: 10788055Abstract: A manipulator for concrete pumps having an articulated boom with at least two boom arms and a hydraulic drive that pivots one or more of the boom arms. A hydraulic cylinder has piston and rod side working volumes. A hydraulic circuit has a first switching state in which the hydraulic circuit connects a first working port for feed or discharge of hydraulic fluid to the rod-side working volume and connects a second working port for feed or discharge of hydraulic fluid to the piston-side working volume. In a second switching state, the hydraulic circuit separates the first working port from the first fluid channel and thereby connects the first fluid channel to the second fluid channel for the feed of hydraulic fluid from the rod-side to the piston side working volume. A sensor acquires an operating state variable based upon which an activation assembly sets the switching state.Type: GrantFiled: October 22, 2019Date of Patent: September 29, 2020Assignee: Putzmeister Engineering GmbHInventors: Martin Diebold, Werner Münzenmaier, Roman Zirbs

Patent number: 9463933Abstract: The invention relates to a hydraulic drive system for a belt conveyor with a motor-driven primary pump which is arranged in a hydraulic primary circuit and is intended for conveying hydraulic fluid, a hydraulic motor which is supplied with hydraulic fluid via the primary circuit and is intended for driving the belt conveyor, and a control device which influences the flow of hydraulic fluid in the primary circuit and is intended for controlling the belt speed of the belt conveyor. In exemplary embodiments, the primary pump is a variable displacement pump and has a pump regulator for regulating the conveyed flow of hydraulic fluid, and the control device comprises a hydraulic control circuit, which is operated by means of an auxiliary pump, for subjecting the pump regulator to an adjustable actuating pressure.Type: GrantFiled: March 26, 2015Date of Patent: October 11, 2016Assignee: Putzmeister Engineering GmbHInventors: Martin Diebold, Martin Mayer, Werner Münzenmaier

Patent number: 9371214Abstract: A locking device for supporting members for a mobile machine, which supporting members are arranged on a chassis or load-bearing frame and can be extended, pivoted or telescoped from a retracted transport position into a deployed working position, has a locking bolt which can be displaced between a locked position and an unlocked position in a guide sleeve which is fixed to the frame and is arranged transversely with respect to the pulling-out direction of the supporting member, which locking bolt is prestressed in the direction of the locked position under the action of a spring, has an actuating member which displaces the locking bolt between the locked position and the unlocked position, and has a latching and guiding member for the locking bolt, which latching and guiding member is arranged rigidly on the supporting member, wherein the latching and guiding member has a guiding curve which pushes the locking bolt into a release slope, and wherein the locking bolt can be moved in the release slope automaticType: GrantFiled: August 21, 2013Date of Patent: June 21, 2016Assignee: Putzmeister Engineering GmbHInventors: Torben Gerlof, Oliver Jaumann, Gernot Goeggelmann, Martin Diebold
