Abstract
(DE)
Die Erfindung bezieht sich auf ein mobiles Arbeitsgerät, insbesondere eine Autobetonpumpe, mit einem Fahrgestell (10), mit zwei vorderen und zwei rückwärtigen, von einer Transportstellung in mindestens eine Arbeitsstellung ausfahrbaren und mit jeweils einem mittels eines Antriebsaggregats telesko-pierbaren Stützbeins (28) auf einem Untergrund (36) abstützbaren Stützaus-legern (22,24). Die Antriebsaggregate der Stützbeine (28) sind über eine rechnergestützte Steuerelektronik (40) ansteuerbar, die mindestens ein von Hand betätigbares Steuerorgan (58,60) aufweist. Erfindungsgemäß ist jedem Stützausleger (22,24) mindestens ein Kraftsensor (38) zur Messung der stützbeinbezogenen Stützkräfte zugeordnet, wobei die Steuerelektronik eine auf Kraftmesswerte (Fi) der Stützkraftsensoren (38) sowie einen vorgegebe-nen minimalen Vergleichswert (Fmin) ansprechende Auswerteroutine zur An-steuerung der Antriebsaggregate mindestens eines ausgewählten Stützbeins (38) aufweist. Eine Besonderheit der Erfindung besteht darin, dass die Steu-erelektronik (40) eine Auswerteroutine (B,C) zur gekoppelten Ansteuerung der Antriebsaggregate der vier Stützbeine (28) mit Hilfe eines handbetätigten Steuerorgans (58,60) aufweist.
(EN)
The invention relates to a mobile working device, particularly an auto-concrete pump, comprising a chassis (10), two front and two rear supporting extension arms (22,24) which can rest on a base (36) and which can be moved outwards from a transport position into at least one working position and which are respectively supported with the aid of a telescopic supporting leg (28) which can be driven by means of a drive unit. The drive units of the supporting legs (28) can be controlled by means of a computer-assisted control electronics system (40) comprising at least one manually actuated control element (58,60). According to the invention, at least one force sensor (38) is associated with each supporting extension arm (22,24) in order to measure the supporting forces relating to the supporting legs, wherein the control electronics system is provided with an evaluation routine which reacts to the force measurement values (Fi) of the supporting force sensors (38) and a predefined minimum comparative value (Fmin) in order to control the drive units of at least one selected supporting leg (38). One particularity of the invention is that the control electronics system (40) is provided with an evaluation routine (B,C) to ensure coupled control of the drive units of the four supporting legs (28) with the aid of a manually actuated control element (58,60).

L'invention concerne un outillage mobile, en particulier une pompe à béton automatique, comprenant un châssis (10), deux bras avant et arrière d'extension (22, 24) de support, lesquels peuvent reposer sur une base (36) et qui peuvent être déplacés d'une position de transport dans une position de travail et qui sont supportés respectivement à l'aide d'une tige de support (28) télescopique, laquelle peut être commandée au moyen d'une unité de commande. Les unités de commande des tiges de support (28) peuvent être commandées au moyen d'un système électronique (40) à commande assistée par informatique, comprenant au moins un élément (58, 60) de commande activé manuellement. Selon l'invention, au moins un détecteur de force (38) est associé à chaque bras (22, 24) d'extension de support, de manière à mesurer les forces de support concernant les tiges de support, le système d'électronique de commande étant pourvu d'une routine d'évaluation qui réagit aux valeurs de mesure de la force (Fi) des détecteurs de force (38) de support et une valeur (Fmin) comparative minimum, permettant de commander les unités de commande d'au moins une tige (38) de support sélectionnée. Une des particularités de l'invention, est que le système d'électronique de commande (40) est doté d'une routine d'évaluation (B, C), assurant la commande couplée des unités de commande des quatre tiges de support (28) à l'aide d'un élément de commande (58, 60) activé manuellement.
