Abstract

A refuse collection vehicle is described, having a lifting-and-tilting or tilting apparatus arranged at the rear and at least one step (7) which can be moved out of a position of rest into the position of use. The step (7) triggers at least one contact switch (11) which interacts electrically, via a control unit (17), with reference contact switches (18, 19). As a result, firstly the moving-out of the step (7) is permitted or prevented as a function of the raised position of the lifting-and-tilting or tilting apparatus, and secondly the lifting-and-tilting or tilting apparatus is locked when the step (17) is moved out. The step can be arranged to be pivotally guided on connecting arms (8, 9) of the supporting cross-pieces (5, 6) extending rearwards from the back of the refuse collection vehicle (1) in its lower region. <IMAGE>

Description

Die Erfindung betrifft ein Müllfahrzeug mit einer am Heck angeordneten Hubkipp- oder Kippvorrichtung zur Entleerung von Müllbehältern in die Einschüttöffnung des Sammelbehälters und mindestens einem aus einer Ruhestellung in die Gebrauchsstellung ausfahrbaren Trittbrett, auf dem ein Müllwerker während der Sammelfahrt stehend mitfahren kann.The invention relates to a garbage truck with a lifting and tipping device arranged at the rear for emptying garbage containers into the pouring opening of the collecting container and at least one running board which can be extended from a rest position into the use position and on which a garbage collector can ride while standing during the collecting trip.

Müllfahrzeuge dieser Art sind hinreichend bekannt, sie werden auch als sogenannte Hecklader bezeichnet. Hierbei ist üblicherweise eine Hubkipp- oder Kippvorrichtung - im folgenden Schüttung genannt - zur Entleerung der Müllbehälter am Heck des Fahrzeuges angeordnet.Refuse collection vehicles of this type are well known, they are also referred to as so-called rear loaders. In this case, a lifting and tipping device - in the following called a bed - is usually arranged at the rear of the vehicle for emptying the waste containers.

Man unterscheidet diese Schüttungen in Hubkippvorrichtungen und Kippvorrichtungen einerseits und in Einzelschüttungen, Doppelschüttungen oder Kombischüttungen andererseits. Allen gemeinsam ist, daß die Breite der Einfüllöffnung auch in etwa der Breite der jeweiligen Schüttung entspricht. Die Breite und Art der Schüttung wird insbesondere dadurch bestimmt, welche Art und Größe von Müllbehältern im Sammelgebiet zur Entleerung anstehen. So gibt es z.B. auch solche Müllfahrzeuge, bei welchen die Schüttung sich über die gesamte Breite des Sammelbehälters erstreckt und der Sammelbehälter keine von seinem Innenmaß wesentlich abweichende Größe der Einfüllöffnung aufweist. Je nach Breite der Schüttung sind links und rechts davon Trittbretter angeordnet, auf denen die Müllwerker bei der Weiterfahrt des Müllfahrzeugs zwischen den Sammelstationen stehend mitfahren können.A distinction is made between these beds in lifting and tipping devices and tipping devices on the one hand and in single beds, double beds or combination beds on the other. Common to all is that the width of the filling opening also approximately corresponds to the width of the respective bed. The width and type of the filling is determined in particular by the type and size of waste containers in the collection area that are to be emptied. For example, there are also refuse collection vehicles in which the fill extends over the entire width of the collecting container and the collecting container does not have a size of the filling opening that differs significantly from its internal dimensions. Depending on the width of the fill, footboards are arranged to the left and right of it, on which the garbage collectors can ride when the garbage truck continues between the collection stations.

Diese Trittbretter sind häufig hochklappbar oder auch wegschwenkbar ausgebildet, um sie bei notwendiger Rückwärtsfahrt nicht zu beschädigen, oder weil sie bei der Entleerung größerer Behälter störend sind.These running boards are often designed to be folded up or swung away so as not to damage them when driving backwards, or because they are disruptive when emptying larger containers.

Die Anordnung von Trittbrettern an Müllfahrzeugen mit Einschüttvorrichtungen der zuvor beschriebenen Art kann zwar grundsätzlich als gelöst angesehen werden, jedoch ist die bekannte Anordnung schwierig, wenn am Heck des Fahrzeugs zwei oder mehr Schüttungen angeordnet werden sollen, die die gesamte Breite des Fahrzeugs beanspruchen, oder Fahrzeuge von geringer Breite zum Einsatz kommen, bei denen neben der oder den Schüttungen kein Raum verbleibt, um ein Trittbrett anzubringen.The arrangement of footboards on garbage trucks with pouring devices of the type described above can in principle be considered as solved, but the known arrangement is difficult if two or more beds are to be arranged at the rear of the vehicle, which occupy the entire width of the vehicle, or vehicles Small widths are used, where there is no space next to the fill (s) to attach a running board.

Für diesen Fall wurde ein Trittbrett unten an der Ladewanne des Sammelbehälters so angeordnet, daß die Müllwerker auf dem Trittbrett nicht neben sondern hinter der Schüttung stehend mitfahren können.In this case, a footboard was arranged at the bottom of the loading trough of the collecting container so that the garbage workers can ride on the footboard, not next to but behind the bed.

Es sind fest angeordnete Trittbretter bekannt oder auch solche, die zwar wegschwenkbar sind, aber trotzdem in ihrer Gebrauchsstellung den Schüttungsbetrieb nicht behindern. Das hat aber zur Folge, daß die Müllwerker die Weiterfahrt bereits signalisieren ohne die Schüttung in eine gesicherte, angehobene Position zu bringen. D.h. die Weiterfahrt zum nächsten Standplatz wird mit abgesenkter Schüttung durchgeführt, die dann bei der Fahrt über unebene Wege oder andere Hindernisse leicht beschädigt werden kann.Fixed running boards are known or also those that can be swung away, but still do not hinder the bulk material operation in their position of use. However, this has the consequence that the garbage workers signal the onward journey without moving the dump into a secured, raised position. I.e. the next trip to the next parking space is carried out with a lowered fill, which can then be easily damaged when driving over uneven paths or other obstacles.

Aus der DE 37 29 107 A1 ist ein Sammelfahrzeug mit einer Rückfahrsicherung bekannt, bei dem die Trittbretter bei Auflast einen Kontaktschalter auslösen. Wenn ein Müllwerker auf dem Trittbrett steht und der Fahrer des Sammelfahrzeuges den Rückwärtsgang einlegt, wird über ein Relais der Motor ausgeschaltet. Es ist auch vorgesehen, daß bei Einlegen des Rückwärtsgangs automatisch die Trittbretter zurückgeschwenkt werden, so daß die Müllwerker erst gar nicht aufsteigen können. Hierbei sind die Trittbretter außerhalb des Arbeitsbereichs des Beladewerks über einen Schwenkhebel mit Gelenken am Fahrgestell befestigt und schwenken unter das Fahrgestell. Sowohl bei eingeschwenkter als auch bei ausgeschwenkter Stellung der Trittbretter ist eine Weiterfahrt möglich, ohne daß zuvor die Schüttung in eine sichere Position angehoben werden muß.From DE 37 29 107 A1 a collecting vehicle with a reversing device is known, in which the Trigger a contact switch under load. When a garbage collector stands on the running board and the driver of the collecting vehicle engages reverse gear, the motor is switched off via a relay. It is also provided that when the reverse gear is engaged, the running boards are automatically pivoted back so that the garbage workers cannot climb up at all. The running boards are attached to the chassis outside the working area of the loading plant by means of a swivel lever and pivot under the chassis. Both when the running boards are swiveled in and when they are swung out, it is possible to continue driving without the bed having to be raised to a safe position beforehand.

Aufgabe der Erfindung ist es, das Trittbrett in Abhängigkeit von der Stellung der Schüttung so anzuordnen und zu steuern, daß Beschädigungen durch den Schüttungsbetrieb vermieden werden und das Trittbrett nur benutzbar ist, wenn die Schüttung vor Weiterfahrt des Müllfahrzeugs in eine angehobene Position gefahren ist.The object of the invention is to arrange and control the running board in dependence on the position of the bed in such a way that damage by the bed operation is avoided and the running board can only be used if the bed has moved into a raised position before the garbage truck continues to travel.

Diese Aufgabe wird mit einer Ausbildung gemäß den kennzeichnenden Merkmalen von Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.This object is achieved with a training according to the characterizing features of claim 1. Advantageous refinements are the subject of the dependent claims.

Die erfindungsgemäße Anordnung des Trittbretts hat den Vorteil einer Zwangssteuerung, die durch Kontakt- und Referenzschalter erreicht wird, die in gegenseitigem Zusammenwirken und Abhängigkeit von der Position von Trittbrett und/oder Schüttungsteilen die Steuerung freigeben oder blockieren.The arrangement of the running board according to the invention has the advantage of a forced control, which is achieved by contact and reference switches, which in mutual interaction and depending on the position of the running board and / or bulk parts release or block the control.

Bei beispielsweise hydraulischer Arbeitsweise werden die entsprechenden Ventile so angesteuert, daß das Trittbrett nur bei angehobener Schüttung der Ruhelage in die Gebrauchslage gebracht werden kann und andererseits die Schüttung nur betriebsbereit ist, wenn das Trittbrett mindestens aus dem unteren Wirkungsbereich der Schüttung entfernt ist.In hydraulic operation, for example, the corresponding valves are controlled so that the footboard can only be brought into the position of use when the bed is in the rest position and the bed is only ready for operation when the footboard is at least removed from the lower effective area of the bed.

Mindestens einer der Kontaktschalter, die vom Trittbrett bzw. dessen Schwenk- oder Befestigungseinrichtung betätigt werden, ist einer Endlage des Trittbretts zugeordnet. Vorteilhafterweise werden im Bereich beider Endlagen des Trittbretts Kontaktschalter zugeordnet, um die korrekte Einnahme der Ruhe- und Gebrauchsstellung überwachen zu können. Zwischen den Endlagen kann noch mindestens ein weiterer Kontaktschalter vorgesehen sein, wenn eine wegabhängige Steuerung, insbesondere eine simultane Bewegung von Hubkipp- oder Kippvorrichtung und Trittbrett, bewerkstelligt werden soll. Die Steuervorrichtung ist in diesem Fall entsprechend ausgebildet.At least one of the contact switches, which are actuated by the running board or its pivoting or fastening device, is assigned to an end position of the running board. Contact switches are advantageously assigned in the area of both end positions of the running board in order to be able to monitor the correct taking of the rest and use positions. At least one further contact switch can be provided between the end positions if a path-dependent control, in particular a simultaneous movement of the lifting and tipping device and the footboard, is to be accomplished. In this case, the control device is designed accordingly.

Durch entsprechende Anzeigeeinrichtungen im Fahrerhaus kann die Position des Trittbretts und/oder der Hubkipp- oder Kippvorrichtung auch vom Fahrer zusätzlich beobachtet und überwacht werden.Corresponding display devices in the driver's cab can also be used to monitor and monitor the position of the footboard and / or the lift and tilt device.

Das Trittbrett kann sich über die gesamte Breite des Fahrzeugs erstrecken. Es können aber auch zwei oder mehr Trittbretter im Arbeitsbereich der Hubkipp- oder Kippvorrichtung vorgesehen sein, wenn dies aufgrund der Bauart des Müllfahrzeugs erforderlich sein sollte.The running board can extend across the entire width of the vehicle. However, two or more running boards can also be provided in the working area of the lifting and tipping device if this should be necessary due to the design of the garbage truck.

Vorzugsweise ist das Trittbrett an Lenkarmen schwenkbar geführt, die an sich vom Heck des Müllfahrzeugs nach hinten erstreckenden Lagertraversen angeordnet sind, welche im unteren Bereich des Mülllfahrzeugs vorgesehen sind. Die Lenkarme schwenken bei dieser Ausführungsform um eine horizontale Achse.The running board is preferably on steering arms pivoted out, which are arranged on the rear of the garbage truck extending rear cross members, which are provided in the lower region of the garbage truck. In this embodiment, the steering arms pivot about a horizontal axis.

Diese Art der Anbringung des Trittbretts hat den Vorteil, daß die Lenkarme je nach Art des Fahrzeugaufbaus abgestimmt werden können und die Anlenkpunkte an der Lagertraverse so gewählt werden können, daß ein ausreichender Schwenkbereich bei optimalem Bodenbestand in Ruhe- und Arbeitsstellung gewährleistet ist.This type of attachment of the footboard has the advantage that the steering arms can be adjusted depending on the type of vehicle construction and the articulation points on the crossbeam can be selected so that a sufficient swivel range is guaranteed with optimal floor space in the rest and working position.

Die Viergelenkführung gemäß einer weiteren Ausführungsform hat den Vorteil, daß an jeder Seite des Trittbretts zwei Lenker angreifen, mit welchen das Trittbrett in einer eindeutig fixierten Lage in Gebrauchs- und Ruhestellung gehalten werden kann. Durch z.B. unterschiedliche Länge der Lenker kann die Stellung des Trittbretts individuell auf das jeweilige Fahrzeug abgestimmt werden.The four-bar guide according to a further embodiment has the advantage that two handlebars engage on each side of the running board, with which the running board can be held in a clearly fixed position in the use and rest position. By e.g. different length of the handlebars, the position of the running board can be individually tailored to the respective vehicle.

In vorteilhafter Weiterbildung bestehen die Lenker jeweils aus parallel zueinander verlaufenden Doppellenkern, die einerseits an der Lagertraverse mittels Gelenkbolzen gelagert sind und damit zwischen sich einen Freiraum zur Aufnahme einer Kolben-Zylindereinheit bilden, die einerseits an der Lagertraverse und andererseits zwischen den Doppellenkern um einen diese verbindenden Bolzen angreift.In an advantageous further development, the control arms each consist of double links running parallel to one another, which are mounted on the bearing crossbar by means of articulated bolts on the one hand and thus form a space between them for receiving a piston-cylinder unit which on the one hand connects to the bearing crossbar and on the other hand between the double links Bolt attacks.

Durch die vorteilhafte Ausbildung der Lagertraversen mit U-förmigem Querschnitt wird die Kolben-Zylindereinheit vor Verschmutzung und äußeren Beschädigungen weitgehend geschützt.Due to the advantageous design of the crossbeams with a U-shaped cross section, the Piston-cylinder unit largely protected from dirt and external damage.

Die Anordnung der Kontaktschalter an einer der Lagertraversen hat den Vorteil, daß sie an beliebiger Stelle in der Bewegungsbahn der Lenker angebracht werden können, um damit den Schaltzeitpunkt zu bestimmen. Außerdem ist die geschützte Anordnung von Schalter und der erforderlichen Zuleitung innerhalb der U-förmigen Lagertraversen ein weiterer Vorteil.The arrangement of the contact switches on one of the bearing traverses has the advantage that they can be attached anywhere in the movement path of the handlebars in order to determine the switching time. In addition, the protected arrangement of switches and the required supply line within the U-shaped bearing cross members is another advantage.

Die Anbringung der Referenz-Kontaktschalter zwischen Hubrahmen und Schwenkarm ermöglicht eine sensible Lagebestimmung des Hubrahmens in der gewünschten Endstellung. Die zusätzlichen Referenz-Kontakt-Schalter zwischen Schwenkarm und Rückwand des Sammelbehälters stellen sicher, daß auch die Schwenkarme in abgesenkter Lage anliegen.The attachment of the reference contact switch between the lifting frame and the swivel arm enables a sensitive determination of the position of the lifting frame in the desired end position. The additional reference contact switches between the swivel arm and the rear wall of the collecting container ensure that the swivel arms are also in a lowered position.

Auf den Lenkarmen 8, 9 sind Schaltfahnen 12 angeordnet, die in der in Figur 1 gezeigten Trittbrettstellung Sensoren 11, wie z.B. an den Lagertraversen 5, 6 angebrachten Näherungsschaltern, gegenüberliegen, so daß durch ein entsprechendes Signal die Hub-Kipp-Vorrichtung mit dem Hubwagen 10 blockiert wird.Switching lugs 12 are arranged on the steering arms 8, 9, the sensors 11 in the running board position shown in FIG. on the bearing crossbars 5, 6 attached proximity switches, opposite, so that the lifting and tilting device with the lifting truck 10 is blocked by a corresponding signal.

Die Figur 2 zeigt das Trittbrett 7 in Ruhestellung bei abgesenktem Hubwagen 10 der Schüttung 2. In dieser Stellung ist der Sensor 11 von der Schaltfahne 12 eines der Lenkarme 9 nicht bedämpft, so daß damit die Schaltung zum Absenken des Hubwagnes 10 freigegeben ist.FIG. 2 shows the running board 7 in the rest position when the lifting truck 10 of the bed 2 is lowered. In this position, the sensor 11 is not damped by the switching flag 12 of one of the steering arms 9, so that the circuit for lowering the lifting carriage 10 is released.

Die Figur 3 zeigt eine Ausführung mit zwei Sensoren 11, 11', mit denen eine Endlagen-Steuerung erreicht wird. D.h. der Hubwagen 10 wird jeweils bei dem Erreichen der Endlage des Trittbretts 7 freigegeben oder blockiert. Hierbei ist die Schaltfahne 12 derart am Lenkarm 9 angeordnet, daß die Sensoren 11, 11' bei Erreichen der jeweiligen Endlage bedämpft werden. Es liegt aber auch im Rahmen der Erfindung, eine wegabhängige Steuerung vorzusehen, bei der ein oder mehrere Sensoren den Weg des Trittbretts überwachen und bereits zu einem Zeitpunkt ein Freigabesignal für das Absenken des Trittbretts erfolgt, damit eine Kollision zwischen Trittbrett und Hubwagen ausgeschlossen werden kann. Bei richtiger Abstimmung ist es vorteilhaft, die Bewegung von Trittbrett und Hubwagen simultan zu steuern, so daß die Bewegung von Hubwagen und Trittbrett über eine einzige Auslösetaste gleichzeitig erfolgen kann.FIG. 3 shows an embodiment with two sensors 11, 11 'with which an end position control is achieved. Ie the lifting truck 10 is released or blocked when the end position of the running board 7 is reached. Here, the switching flag 12 is arranged on the steering arm 9 such that the sensors 11, 11 'are damped when the respective end position is reached. However, it is also within the scope of the invention to provide a path-dependent control in which one or more sensors monitor the path of the running board and a release signal for lowering the running board is given at a time so that a collision between running board and lifting truck can be ruled out. With correct coordination, it is advantageous to control the movement of the footboard and pallet truck simultaneously, so that the movement of the pallet truck and footboard can take place simultaneously via a single trigger button.

In jedem Fall ist es erforderlich, daß die jweilige Position des Trittbretts 7 auch im Fahrerraum signalisiert wird, so daß sichergestellt ist, daß der Fahrer keienswegs vor Erreichen der Endstellung (Gebrauchsstellung) des Trittbretts 7 weiterfährt.In any case, it is necessary that the respective position of the footboard 7 is also signaled in the driver's compartment, so that it is ensured that the driver does not drive on the footboard before reaching the end position (use position) of the footboard 7.

Der Antrieb für die Bewegungen des Trittbretts 7 erfolgt über eine Kolben-Zylinder-Einheit 13, 13', die an das hydraulische System der Schüttung 2 bzw. des Fahrzeugs 1 angeschlossen ist. Dabei ist es vorteilhaft, die Kolben-Zylinder-Einheit 13, 13' wie in Figur 2 und 3 gezeugt, so anzuordnen, daß sie von den U-förmig ausgebildeten Lagertraversen 5, 6 teilweise oder völlig überdeckt sind. Im gezeigten Beispiel sind die Zylinder an den Lagertraversen 5, 6 gelagert, während die Kolben zwischen je einem der Doppellenker der Lenkarme 8, 9 an einem diese verbindenden Bolzen 14 angreifen.The movement of the footboard 7 is driven by a piston-cylinder unit 13, 13 ', which is connected to the hydraulic system of the bed 2 or the vehicle 1. It is advantageous to arrange the piston-cylinder unit 13, 13 'as shown in FIGS. 2 and 3 so that they are partially or completely covered by the U-shaped bearing cross members 5, 6. In the example shown, the cylinders are mounted on the bearing cross members 5, 6, while the pistons engage between one of the double links of the steering arms 8, 9 on a bolt 14 connecting them.

Die Auslösung der Bewegung erfolgt elektrisch über die Taster 15, 16 und ein Steuergerät 17 (s. Figur 4), welches zunächst die Stellung von Hubwagen 10, Schwenkarm und Trittbrett 1 über die Sensoren 11, 11' und Referenz-Sensoren 18, 18', 19, 19' überprüft und erst nach dem Vorliegen der entsprechenden Freigabe-Signale die Steuerung in der gewünschten Weise einleitet. Im hier beschriebenen Beispiel heißt das, daß die angesteuerten Elektromagnetventile das Hydrauliksystem offen oder blockiert sind.The movement is triggered electrically via the buttons 15, 16 and a control device 17 (see FIG. 4), which first of all controls the position of the lifting truck 10, swivel arm and running board 1 via the sensors 11, 11 'and reference sensors 18, 18'. , 19, 19 'is checked and the control is initiated in the desired manner only after the corresponding enable signals have been received. In the example described here, this means that the actuated solenoid valves of the hydraulic system are open or blocked.

Die Figur 4 zeigt schematisch die Anordnung der Kontaktschalter 11, 11' (Sensoren) und der Referenz-Kontaktschalter 18, 18', 19, 19' (Sensoren), die über elektrische Leitungen 25 mit dem Steuergerät 17 verbunden sind, welches über die Taster 15, 16 aktiviert wird und dann über Elektromagnetventile 21, 22, 23 die Kolben-Zylinder-Einheiten 13, 13' beaufschlagt.FIG. 4 schematically shows the arrangement of the contact switches 11, 11 '(sensors) and the reference contact switches 18, 18', 19, 19 '(sensors), which are connected via electrical lines 25 to the control device 17, which is connected via the Button 15, 16 is activated and then applied to the piston-cylinder units 13, 13 'via electromagnetic valves 21, 22, 23.

Die Figur 5 zeigt in schematischer Darstellung eine elektrohydraulische Schaltung. Mit dem Taster 15 wird ein Signal an das Steuergerät 17 zum Ausfahren des Trittbretts 7 gegeben. Das Steuergerät 17 überprüft, ob die entsprechenden Bedingungen vorliegen, um das Trittbrett 7 ausschwenken zu lassen. Die Überprüfung dieser Bedingungen muß ergeben, daß die Sensoren 18, 18' bedämpft sind zum Zeichen dafür, daß der/die Hubwagen 10 angehoben sind. Die Überwachung durch die Sensoren 19, 19' dient zur Feststellung, ob die Schwenkarme 20 des Hubwagens 10 im abgesenkten Zustand anliegen oder nicht. Liegen alle Bedingungen vor, wird das Magnetventil 21 geöffnet und das Druckmittel gelangt in die Zylinder/Kolbeneinheiten 13, 13', um das Trittbrett 7 auszuschwenken. In dieser Stellung wird der Endlage-Sensor 11 von dem Lenkarm 9 des Trittbretts bedämpft und das Steuergerät 17 blockiert die Stromzufuhr zum Magnetventil 23. Damit wird der Hydraulikstrom zur Schüttung unterbrochen.Figure 5 shows a schematic representation of an electro-hydraulic circuit. With the button 15, a signal is given to the control unit 17 for extending the running board 7. The control unit 17 checks whether the corresponding conditions exist in order to allow the running board 7 to swing out. Checking these conditions must show that the sensors 18, 18 'are damped as a sign that the lift truck (s) 10 are raised. The monitoring by the sensors 19, 19 'serves to determine whether the swivel arms 20 of the lifting truck 10 are in contact in the lowered state or not. If all conditions are present, the solenoid valve 21 is opened and the pressure medium enters the cylinder / piston units 13, 13 'in order to swing out the footboard 7. In this position, the end position sensor 11 is damped by the steering arm 9 of the running board and the control unit 17 blocks the current supply to the solenoid valve 23. This interrupts the hydraulic flow to the bed.

Mit dem Taster 16 wird ein Signal an das Steuergerät 17 zum Einschwenken des Trittbretts 7 gegeben. Dabei wird in gleicher Reihenfolge über das Steuergerät 17 geprüft, ob die Bedingungen zur Wegbewegung des Trittbretts 7 erfüllt sind. Nach Freigabe wird das Magnetventil 22 angesteuert und der Hydraulikstrom zu den Kolben/Zylindereinheiten geleitet, die das Trittbrett 7 in die Ruhelage einschwenken. Mit der gleichzeitig oder verzögert erfolgten Freigabe des Magnetventils 23 wird auch der Schüttungsantrieb (nicht dargestellt) mit Druckmittel beaufschlagt und kann in bekannter Weise in Betrieb genommen werden. Ein in den Druckmittelkreislauf für das Einschwenken des Trittbretts 7 eingesetzter Druckspeicher 24 verhindert das Absenken bzw. Ausschwenken des eingefahrenen Trittbretts 7. Ein weiterer Endlage-Sensor 11' kontrolliert diese eingefahrene Stellung und gibt ein Signal an das Steuergerät 17, wenn die vorgegebene Bedingung nicht mehr vorliegt, mit der Folge, daß das Magnetventil 23 geschlossen wird und der Druckmittelfluß zum Lifterantrieb unterbrochen wird.With the button 16, a signal is given to the control unit 17 for pivoting the footboard 7. It is checked in the same order via the control unit 17 whether the conditions for moving the running board 7 are met. After release, the solenoid valve 22 is actuated and the hydraulic flow is directed to the piston / cylinder units which pivot the running board 7 into the rest position. With the release of the Solenoid valve 23 is also applied to the bulk drive (not shown) with pressure medium and can be put into operation in a known manner. A pressure accumulator 24 inserted into the pressure medium circuit for swiveling the running board 7 prevents the retracted running board 7 from being lowered or swung out. A further end position sensor 11 'checks this retracted position and sends a signal to the control unit 17 when the specified condition no longer exists is present, with the result that the solenoid valve 23 is closed and the pressure medium flow to the lifter drive is interrupted.

In dem beschriebenen Beispiel handelt es sich um ein Steuergerät mit Relais-Schaltungen für die einzelnen Bewegungsabläufe. Es liegt aber auch im Rahmen der Erfindung, diese Schaltung durch eine elektronische programmierbare Steuerung zu ersetzen. Durch eine entsprechende Steuerung kann auch eine simultane Bewegung von Hubwagen und Trittbrett ermöglicht werden.In the example described, it is a control device with relay circuits for the individual movement sequences. However, it is also within the scope of the invention to replace this circuit with an electronic programmable controller. Appropriate control can also enable simultaneous movement of the pallet truck and running board.
