This allows the cable, which is usually led directly from the energy store to the electric motor of the drive device for controlling the hydraulic unit, to be led over the control board, whereby the energy consumption for the activation of the tion of the control device on the one hand monitored and at the same time the state of charge of the energy storage is detected to timely display a recharge of the energy storage device on the display device.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die Steuerplatine als Not-Aus-Schalter ausgebildet ist, wobei alle Anschlüsse derart an der Steuerplatine angeordnet sind, dass die Steuerplatine durch eine einfache Abziehbewegung von allen Anschlüssen trennbar ist. Dies ermöglicht, dass in einfacher Weise ein Not-Aus erzielt werden kann. Gleichzeitig wird dadurch aber auch wieder eine einfache Inbetriebnahme ermöglicht. Zudem kann durch ein Bedienpersonal ein Komplettaustausch der Steuerplatine erfolgen, ohne dass dafür ein Fachpersonal erforderlich ist. According to a further advantageous embodiment of the invention it is provided that the control board is designed as an emergency stop switch, wherein all terminals are arranged on the control board, that the control board is separable by a simple Abziehbewegung of all terminals. This allows an emergency stop to be easily achieved. At the same time, however, this also makes easy commissioning possible again. In addition, a complete exchange of the control board can be carried out by an operator, without the need for a specialist staff is required.
Die Aufgabe wird des Weiteren erfindungsgemäß durch ein Verfahren zum Prüfen und Überwachen einer Hebevorrichtung, insbesondere einer Einsäulen-Hebebühne zum Heben und Senken von Lasten, die mit zumindest einer weiteren Einsäulen-Hebebühne ein Hebesystem bildet, gelöst, bei welchem beim Einschalten der Hebevorrichtung durch eine Auswerteeinrichtung auf einer Steuerplatine der Antriebssteuerung, an welcher die Anschlüsse des zumindest einen Energiespeicher, der Ladeeinrichtung, der Antriebseinrichtung und des zumindest einen Sensors und/oder des zumindest einen Aktors angeschlossen ist, von jeder angeschlossenen Komponente ein Stromprofil abgefragt und ausgewertet wird. Aufgrund der unterschiedlichen Leitungsquerschnitte und der verschiedenen Widerstände der einzelnen Komponenten kann sowohl eine einfache Zuordnung der abgefragten Stromprofile zu den Anschlussleitungen und/oder Komponenten ermöglicht werden. Darüber hinaus kann eine Selbstdiagnose stattfinden, ob die einzelnen Anschlussleitungen in Ordnung oder beschädigt sind und/oder ob die einzelnen Komponenten noch funktionsfähig und angeschlossen sind. Dadurch wird beim Einschalten der Hebevorrichtung eine Selbstdiagnose durchgeführt und sichergestellt, dass die weitere Inbetriebnahme zum Heben und Senken von Lasten nur dann durchgeführt wird, wenn durch die Selbstdiagnose die Hebevorrichtung als ordnungsgemäß detektiert wird. Eine weitere bevorzugte Ausgestaltung der Erfindung sieht vor, dass vor, während oder nach dem Anheben und Senken der Lastaufnahme das Stromprofil der einzelnen Komponenten überwacht wird. Dadurch können einzelne Zustände erfasst und insbesondere auf der Anzeigenvorrichtung ausgegeben werden. Sollten einzelne Zustände von den zugelassenen Stromprofilen abweichen, wird eine Fehlermeldung ausgegeben. Darüber hinaus kann nicht nur eine Fehlermeldung ausgegeben werden, sondern auch spezifisch angezeigt werden, welche Komponenten fehlerhaft sind oder die Fehlermeldung verursacht haben. The object is further achieved according to the invention by a method for testing and monitoring a lifting device, in particular a single-column lift for lifting and lowering of loads, which forms a lifting system with at least one further single-column lift, wherein when switching the lifting device by a Evaluation device on a control board of the drive control, to which the terminals of the at least one energy storage, the charging device, the drive device and the at least one sensor and / or the at least one actuator is connected, queried from each connected component, a current profile and evaluated. Due to the different conductor cross sections and the different resistances of the individual components, both a simple assignment of the queried current profiles to the connecting lines and / or components can be made possible. In addition, a self-diagnosis can take place, whether the individual connection lines are in order or damaged and / or whether the individual components are still functional and connected. As a result, a self-diagnosis is carried out when the lifting device is switched on and it is ensured that the further start-up for lifting and lowering loads is only carried out if the lifting device is correctly detected by the self-diagnosis. A further preferred embodiment of the invention provides that the current profile of the individual components is monitored before, during or after the lifting and lowering of the load suspension. As a result, individual states can be detected and in particular output on the display device. If individual states deviate from the permitted current profiles, an error message is output. In addition, not only can an error message be issued, but also specific information about which components are faulty or caused the error message.
Eine weitere bevorzugte Ausgestaltung der Erfindung sieht vor, dass der Ladezustand des zumindest einen Energiespeichers abgefragt und überwacht wird. Durch die zentrale Zuführung von allen Anschlüssen beziehungsweise Leitungen der Hebevorrichtung über die Steuerplatine wird vor und/oder während des Betriebes als auch nach dem Betrieb der Ladezustand des Energiespeichers erfasst. Dadurch wird bei Unterschreiten eines vorbestimmten Schwellwertes des Ladezustandes ein Signal zum Aufladen des Energiespeichers ausgegeben, wobei der Schwellwert derart bemessen ist, dass der Arbeitszyklus noch kontrolliert zu Ende geführt werden kann. A further preferred embodiment of the invention provides that the state of charge of the at least one energy store is queried and monitored. Due to the central supply of all terminals or lines of the lifting device via the control board is detected before and / or during operation as well as after operation of the state of charge of the energy storage. As a result, a signal for charging the energy store is output when falling below a predetermined threshold value of the state of charge, wherein the threshold value is dimensioned such that the duty cycle can still be performed controlled to the end.
Nach einer weiteren bevorzugten Ausgestaltung des Verfahrens ist vorgesehen, dass während eines Ladevorganges des zumindest einen Energiespeichers der Ladezustand des Energiespeichers durch die Auswerteeinrichtung der Steuerplatine überwacht und die Ladeeinrichtung durch die Auswerteeinrichtung angesteuert wird. Dies ermöglicht, dass ein einfaches Netzteil genügt, wodurch eine Kostenreduzierung erzielt wird. According to a further preferred embodiment of the method, it is provided that, during a charging process of the at least one energy store, the charge state of the energy store is monitored by the evaluation device of the control board and the charging device is controlled by the evaluation device. This allows a simple power supply to suffice, thereby achieving a cost reduction.

An der Basiseinrichtung 12 ist eine Hubsäule 14 vorgesehen. An der Hubsäule 14 ist eine Antriebseinrichtung 15 befestigt, welche einen Träger 16 relativ zur Hubsäule 14 auf und ab bewegt. An dem Träger 16 ist ein Lastaufnahmemittel 17 vorgesehen, welches eine zu hebende Last untergreift. Bevorzugt ist das Lastaufnahmemittel als Radgreifelement ausgebildet. Andere Anwendungen sind ebenfalls möglich. Die Antriebseinrichtung 15 umfasst ein Hydraulikaggregat 21, welches einen Antriebszylinder, der bevorzugt innerhalb des Trägers 16 angeordnet ist, antreibt. Alternativ kann die Antriebseinrichtung auch als elektrischer oder mechanischer Antrieb ausgebildet sein, so dass beispielsweise auch ein Spindelantrieb oder dergleichen ansteuerbar ist. Zur Ansteue- rung des Hydraulikaggregates 21 ist eine hydraulische Steuerung 23 vorgesehen, welche von einer Antriebssteuerung 25 angesteuert wird. Zur hydraulischen Steuerung der Antriebseinrichtung 15 sind Aktoren 24, wie beispielsweise ein Proportionalventil, ein Senkventil und/oder ein Motorregelventil vorgesehen. The single-column lift 11 has a base device 12, which according to the embodiment preferably comprises a chassis or steering gear. Alternatively, the base means 12 may be formed as a support plate or mounting plate to which the single-column lift 11 is attached to the floor of a workshop or a mobile or a stationary work space. At the base device 12, a lifting column 14 is provided. At the lifting column 14, a drive device 15 is attached, which moves a carrier 16 relative to the lifting column 14 up and down. On the carrier 16, a load-receiving means 17 is provided, which engages under a load to be lifted. Preferably, the load-receiving means is designed as a wheel gripping element. Other applications are also possible. The drive device 15 comprises a hydraulic unit 21, which drives a drive cylinder, which is preferably arranged within the carrier 16. Alternatively, the drive device can also be designed as an electrical or mechanical drive, so that, for example, a spindle drive or the like can be controlled. To actuate the hydraulic unit 21, a hydraulic control 23 is provided, which is controlled by a drive control 25. For hydraulic control of the drive device 15 actuators 24, such as a proportional valve, a lowering valve and / or a motor control valve are provided.
Zwischen der Antriebssteuerung 25 und der hydraulischen Steuerung 23 ist ein Elektromotor 26 vorgesehen, der wiederum das Hydraulikaggregat 21 antreibt. Oberhalb der Antriebssteuerung 25 ist eine Schnellwechseleinrichtung 28 vorgesehen, welche einen oder mehrere Energiespeicher 29 zur Energieversorgung der Einsäulen-Hebebühne 11 auswechselbar aufnimmt. Diese Schnellwechseleinrichtung 28 kann auch Teil einer Montageplatte 35 oder als Montageplatte 38 zur Aufnahme der Energiespeicher 29 und/oder der Antriebssteuerung 25 und/oder der Antriebseinrichtung 15 vorgesehen sein. Die Montageplatte 38 kann ebenfalls in einfacher Weise an der Hubsäule 14 befestigt werden, wobei die Komponenten der Antriebseinrichtung 15 an der Montageplatte 35 vormontierbar sind. Between the drive control 25 and the hydraulic control 23, an electric motor 26 is provided, which in turn drives the hydraulic unit 21. Above the drive control 25, a quick-change device 28 is provided, which receives one or more energy storage 29 replaceable for powering the single-column lift 11. This quick-change device 28 can also be provided as part of a mounting plate 35 or as a mounting plate 38 for receiving the energy store 29 and / or the drive control 25 and / or the drive device 15. The mounting plate 38 can also be attached in a simple manner to the lifting column 14, wherein the components of the drive means 15 are preassembled on the mounting plate 35.
Am oberen Ende der Hubsäule 14 ist beispielsweise ein Sensor 30 zur Erkennung einer oberen Hubendlage vorgesehen. Des Weiteren ist am oberen Ende der Hubsäule 14 ein Aktor 31 vorgesehen, der als Fallsicherung ausgebildet ist und einen Entriegelungsmagneten umfasst. Dieser Entriegelungsmagnet wird über eine Spule angetrieben, und dadurch kann die Spule auch als Sensor eingesetzt werden, um die Position der Fallsicherung abzufragen. At the upper end of the lifting column 14, for example, a sensor 30 is provided for detecting an upper stroke end position. Furthermore, an actuator 31 is provided at the upper end of the lifting column 14, which is designed as a fall arrester and comprises an unlocking magnet. This unlocking magnet is driven by a coil, and thereby the coil can also be used as a sensor to interrogate the position of the fall arrester.
Die Antriebssteuerung 25 umfasst eine Steuerplatine 33, welche bevorzugt an der Montageplatte 35 ansteckbar und somit einfach austauschbar befestigt ist. Ebenso ist eine Ladeeinrichtung 36 für den zumindest einen Energiespeicher 29 an der Montageplatte 35 auswechselbar befes- tigt. Die Antriebssteuerung 25 regelt den gesamten Betrieb der Hebevorrichtung 11. The drive control 25 includes a control board 33 which is preferably attached to the mounting plate 35 and thus attached easily replaceable. Likewise, a charging device 36 for the at least one energy storage 29 on the mounting plate 35 interchangeably befes- Untitled. The drive controller 25 controls the entire operation of the elevator 11.
In Figur 2 ist eine schematische Ansicht der Steuerplatine 33 der Antriebssteuerung 25 mit den daran angeschlossenen Komponenten dargestellt. FIG. 2 shows a schematic view of the control board 33 of the drive control 25 with the components connected thereto.
Die Steuerplatine 33 ist als Steckmödul ausgebildet und kann durch Stecken und Ziehen an der Montageplatte 35 befestigt werden. Diese Steuerplatine umfasst mehrere Schaltungskomponenten, insbesondere auch Mikroprozessoren, von denen nur eine Auswerteeinrichtung 38 und ein Strommesswiderstand 39 dargestellt sind. Die Steuerplatine 33 weist einen Anschluss 41, insbesondere einen Hochstromanschluss, auf, an dem ein mit dem zumindest einen Energiespeicher 29 verbundenes Kabel 42 verbunden ist. Ein weiterer Anschluss 43 führt zum Elektromotor. Der durch die Energiespeicher 29 zugeführte Ladestrom wird über den Strommesswiderstand 39 zum Elektromotor 26 geführt. Dadurch wird ein Hochstromkreis gebildet, der über die Steuerplatine 33 geführt ist. The control board 33 is formed as Steckmödul and can be attached by plugging and pulling on the mounting plate 35. This control board comprises a plurality of circuit components, in particular also microprocessors, of which only one evaluation device 38 and one current measuring resistor 39 are shown. The control board 33 has a connection 41, in particular a high-current connection, to which a cable 42 connected to the at least one energy store 29 is connected. Another connection 43 leads to the electric motor. The charging current supplied by the energy store 29 is conducted via the current measuring resistor 39 to the electric motor 26. As a result, a high-current circuit is formed, which is guided via the control board 33.
An der Steuerplatine 33 ist ein weiterer Anschluss 46, insbesondere Steckanschluss, vorgesehen, an welchem der zumindest eine Sensor 30 und der zumindest eine Aktor 31 angeschlossen sind. Des Weiteren ist an dem Steckanschluss 46 die Ladeeinrichtung 36 angeschlossen, welche beispielsweise mit einem Netzanschluss über ein Ladekabel 52 verbunden ist. Alternativ können autonome Energieerzeuger wie Solarmodule, Notstromaggregate und dergleichen den Ladestrom zur Verfügung stellen. Ergänzend können an diesem Steckanschluss 46 noch weitere Sensoren, wie beispielsweise eine Wägezelle oder ein Temperatursensor, angeschlossen sein. Der Steckanschluss 46 wiederum steht mit dem Strommesswiderstand 39 in Verbindung, so dass alle daran angeschlossenen Komponenten mit dem Strommesswiderstand 39 kontaktiert sind. On the control board 33, a further connection 46, in particular plug connection, is provided, to which the at least one sensor 30 and the at least one actuator 31 are connected. Furthermore, the charging device 36 is connected to the plug connection 46, which is connected, for example, to a mains connection via a charging cable 52. Alternatively, autonomous power generators such as solar modules, emergency generators and the like can provide the charging current. In addition, further sensors, such as a load cell or a temperature sensor, may be connected to this plug connection 46. The plug connection 46 in turn is connected to the current measuring resistor 39, so that all components connected thereto are contacted with the current measuring resistor 39.
An der Steuerplatine 33 ist des Weiteren ein Anschluss 48, insbesondere Steckanschluss, vorgesehen, der zur Anzeigeeinrichtung 49, insbesondere einem LCD-Display, führt, an welchem verschiedene Schaltzustände und Informationen der Einsäulen-Hebebühne angezeigt werden können. Ergänzend können ein oder mehrere weitere Schnittstellen oder Anschlüsse 50 vorgesehen sein, wie beispielsweise eine serielle Schnittstelle RS-485, so dass weitere Komponenten daran anschließbar sind. Beispielsweise kann ein GPS-, ein GSM- und/oder ein Funkmodul oder dergleichen anschließbar sein. Furthermore, a connection 48, in particular plug connection, is provided on the control board 33, which leads to the display device 49, in particular an LCD display, on which various switching states and information of the single-column lift can be displayed. In addition, one or more further interfaces or connections 50 may be provided, such as, for example, a serial interface RS-485, so that further components can be connected thereto. For example, a GPS, a GSM and / or a radio module or the like can be connected.
Die Steuerplatine 33 kann des Weiteren einen Anschluss 51 aufweisen, der als ein Service-, Diagnose- und/oder Update-Steckanschluss ausgebildet ist. Dadurch kann nach Anschluss eines externen Gerätes beispielsweise eine Fehlerdiagnose durchgeführt werden. Ebenso können darüber weitere Software-Updates abgespielt werden. An diesen Anschluss können ebenso Funkmodule oder dergleichen angeschlossen werden, um eine externe Sicherheitsüberwachung zu ermöglichen. The control board 33 may further include a terminal 51 which is formed as a service, diagnostic and / or update plug-in connection. As a result, after connection of an external device, for example, a fault diagnosis can be carried out. Likewise, further software updates can be played. Radio modules or the like can also be connected to this connection in order to enable external security monitoring.
Durch diese Anordnung der Anschlussleitungen der einzelnen Komponenten zur Steuerplatine 33 sind alle an der Einsäulen-Hebebühne 11 ansteuerbaren elektrischen Komponenten an der Steuerplatine 33 angeschlossen. Dies ermöglicht eine sternförmige Anordnung der Anschlussleitungen zur Steuerplatine 33. Dadurch wird der Verkabelungsaufwand der einzelnen Komponenten an der Hubsäule 14 vereinfacht. Insbesondere kann dabei vorgesehen sein, dass die Hubsäule 14 selbst als Minuspol bzw. als Nullleiter dient, so dass darüber hinaus eine weitere Einsparung bei der Verlegung von Leitungen zu den einzelnen Komponenten erzielt werden kann. Des Weiteren weist diese sternförmige Anordnung und zentrale Zuführung der einzelnen Anschlussleitungen zur Steuerplatine 33 den Vorteil auf, dass alle Anschlüsse in einfacher Weise über zumindest einen Strommesswiderstand 39 geführt werden können, der die erfassten Stromsignale der angeschlossenen Komponenten an eine Auswerteeinrichtung 38 weitergibt. Dadurch kann eine Selbstdiagnose der angeschlossenen Komponenten beim Einschalten der Einsäulen- Hebebühne 11 ermöglicht werden, indem nacheinander die einzelnen angeschlossenen Komponenten abgefragt werden. Aufgrund der unterschiedlichen Leitungsquerschnitte und der unterschiedlichen Potenziale der daran angeschlossenen Komponenten kann aus dem jeweiligen erfassten Stromprofil der Zustand der jeweiligen Komponente abgefragt und erfasst werden. Eine solche Abfrage und Überwachung kann auch während dem Betrieb der Einsäulen-Hebebühne 11 erfolgen und durch die Auswerteeinrichtung 38 ausgewertet werden. Des Weiteren wird durch die Anbindung der einzelnen Komponenten über Anschlüsse, insbesondere Steckanschlüsse, ein einfacher Austausch einer solchen Steuerplatine 33 ermöglicht. Nach dem Abziehen der Anschlüsse kann die Steuerplatine 33 von der Montageplatte 38 abgezogen und durch eine neue Steuerplatine ersetzt werden. Das Anbringen der Anschlüsse ist unproblematisch, da keiner der Anschlüsse dem anderen gleicht und somit Verwechslungen ausgeschlossen sind. As a result of this arrangement of the connection lines of the individual components to the control board 33, all electrical components which can be activated on the single-column lift 11 are connected to the control board 33. This allows a star-shaped arrangement of the connection lines to the control board 33. This simplifies the cabling of the individual components on the lifting column 14. In particular, it may be provided that the lifting column 14 itself serves as a negative pole or as a neutral conductor, so that, moreover, a further saving in the laying of lines to the individual components can be achieved. Furthermore, this star-shaped arrangement and central supply of the individual connecting lines to the control board 33 has the advantage that all connections can be guided in a simple manner via at least one current measuring resistor 39, which forwards the detected current signals of the connected components to an evaluation device 38. As a result, a self-diagnosis of the connected components when switching on the single-column lift 11 are made possible by successively querying the individual connected components. Due to the different cable cross sections and the different potentials of the components connected thereto, the state of the respective component can be queried and recorded from the respective detected current profile. Such a query and monitoring can also take place during operation of the single-column lift 11 and are evaluated by the evaluation device 38. Furthermore, a simple exchange of such a control board 33 is made possible by the connection of the individual components via connections, in particular plug-in connections. After removing the terminals, the control board 33 can be removed from the mounting plate 38 and replaced with a new control board. The attachment of the connections is not a problem, since none of the connections are the same as the other and thus confusion is excluded.
Diese sternförmige Anordnung der einzelnen Komponenten an der Steuerplatine 33 weist des Weiteren den Vorteil auf, dass beispielsweise während dem Laden des zumindest einen Energiespeichers 29 durch eine Ladeeinrichtung 36, welche an ein öffentliches Stromversorgungsnetz oder an einen Generator oder dergleichen anschließbar ist, der Ladestrom über den Strom messwiderstand läuft. Der Ladestrom und der Ladezustand des Energiespeichers 39 werden durch die Auswerteeinrichtung überwacht. Dadurch kann die Ladeeinrichtung 39 in einfacher Weise nur als Netzteil ausgebildet werden. This star-shaped arrangement of the individual components on the control board 33 further has the advantage that, for example, during charging of the at least one energy storage device 29 by a charging device 36 which is connected to a public power grid or to a generator or the like, the charging current through the Current measuring resistor is running. The charging current and the state of charge of the energy store 39 are monitored by the evaluation device. As a result, the charging device 39 can be formed in a simple manner only as a power supply.
Die Ausgestaltung der Steuerplatine 33 ermöglicht auch, dass ein Motorstrom für den Elektromotor 26 der Antriebseinrichtung 15, ein Ladestrom für die Energiespeicher 29 und ein Versorgungsstrom für die Sensoren 30 und/oder Aktoren 24, 31 gesamthaft über die Steuerplatine 33 geführt werden, wodurch eine vollständige Überwachung und Diagnose der Komponenten der Einsäulen-Hebebühne 11 sowie die Ermittlung einer Energiebilanz der Energiespeicher 29 ermöglicht wird. The design of the control board 33 also allows a motor current for the electric motor 26 of the drive device 15, a charging current for the energy storage 29 and a supply current for the sensors 30 and / or actuators 24, 31 are performed in total on the control board 33, whereby a complete Monitoring and diagnosis of the components of the single-column lift 11 and the determination of an energy balance of the energy storage 29 is made possible.
Bei der Anordnung von einem GSM-Modul oder eines weiteren Computers mit einem Internetzugang wird darüber hinaus auch eine Fernwartung bzw. Ferndiagnose als auch gegebenenfalls ein Aufspielen einer neuen Programmversion zur Ansteuerung der Einsäulen-Hebebühne 11 die Abfrage eines Betriebsprotokolls möglich. In the arrangement of a GSM module or another computer with an Internet access is also a remote maintenance or remote diagnosis and possibly a Aufspielen a new program version for controlling the single-column lift 11, the query of an operating log possible.
Die Steuerplatine 33 weist bevorzugt eine Leitungsstruktur sowie eine Anordnung der Anschlüsse 41, 43, 46, 48 und/oder 50 auf, die derge- stalt angeordnet sind, dass die Steuerplatine 33 als Not-Aus-Schalter ausgebildet ist. Dies bedeutet, dass durch ein einfaches Abziehen dieser Steuerplatine 33 alle angeschlossenen Komponenten über deren Anschlüsse in einfacher weise getrennt werden können. Diese vorteilhafte Ausgestaltung der Steuerplatine 33 ermöglicht, dass auf eine separate Ausgestaltung eines Not-Aus-Schalters verzichtet werden kann. The control board 33 preferably has a line structure and an arrangement of the terminals 41, 43, 46, 48 and / or 50, which are Stalt are arranged, that the control board 33 is formed as an emergency stop switch. This means that by simply pulling off this control board 33 all connected components can be disconnected via their connections in a simple manner. This advantageous embodiment of the control board 33 allows that can be dispensed with a separate embodiment of an emergency stop switch.
In den Figuren 3 und 4 ist die Montageplatte 35 mit den beispielsweise daran anordenbaren Komponenten der Einsäulen-Hebebühne 11 dargestellt. Diese Anordnung in den Figuren 3 und 4 bildet eine In Figures 3 and 4, the mounting plate 35 is shown with the example of it can be arranged components of the single-column lift 11. This arrangement in Figures 3 and 4 forms a
vormontierbare Baugruppe, welche darüber hinaus auch auf die Funktion geprüft werden kann. Somit kann diese vorgefertigte Baugruppe unmittelbar an die Hubsäule 14 der Einsäulen-Hebebühne in einfacher Weise montiert werden. Alternativ kann die Montageplatte 35 auch zweiteilig ausgebildet sein, so dass beispielsweise die hydraulische Steuerung separat an einer Montageplatte angeordnet ist. Pre-assembled module, which can also be tested on the function. Thus, this prefabricated assembly can be mounted directly to the lifting column 14 of the single-column lift in a simple manner. Alternatively, the mounting plate 35 may be formed in two parts, so that, for example, the hydraulic control is arranged separately on a mounting plate.
Die vorgenannte Ausgestaltung der Steuerplatine 33 für Hebevorrichtungen 11 kann insbesondere bei Einsäulen-Hebebühnen, bei Fahrschienen- Bühnen als auch bei weiteren Hebevorrichtungen zum Heben von Fahrzeugen jeglicher Art als auch Sonderfahrzeugen vorgesehen sein. The aforementioned embodiment of the control board 33 for lifting devices 11 may be provided in particular in single-column lifts, on platforms rails as well as other lifting devices for lifting vehicles of any kind as well as special vehicles.
