- the invention relates to a reach truck, which is equipped with a Zinkenverstell réelle for laterally adjusting the individual load tines.
- a limit switch system it is known to detect the center position of a fork carriage and a safety height of the forks in a side slide provided on the mast.
- the well-known limit switch system provides to release a lifting and tilting of the fork in principle, but if the fork carriage is below the safety height of 500 to 600 mm, to turn off all other hydraulic functions.
- the mast is fully advanced and the fork is below the safety height, retraction of the mast is blocked by the known limit switch system.
- the other functions are unlocked.
- the known limit switch the functions for further lowering the fork, the mast, the side thrust and additional hydraulic functions such as a lateral fork adjustment.
- the hydraulic function for the mast thrust and the lowering is automatically released on reaching the central position of the fork carriage, while the other hydraulic functions remain locked.
- a lifting and tilting is basically release and other hydraulic functions when the fork carriage has a minimum height of 500 to 600 mm or more. With the mast fully extended and the forks below the safety height, mast retraction is disabled while all other functions remain enabled. If the mast is not completely advanced and the forks are below the safety height, further lowering of the forks, a mast thrust, a side thrust and additional hydraulic functions such as a fork adjustment are blocked. The blocking is canceled via the additional bridging button. Locked hydraulic functions can be enabled as long as the button is pressed. In the known limit switch system is a lifting of the lock without actuation of the lock-up button when the associated actuator undergoes a zero crossing to the respective function. In this case, the blocking of the corresponding function is then canceled and continued at a lower speed.
- Out DE 103 05 901 A1 is a reach truck with a mast known, which is by means of a mast drive to a drive part of the truck to and away from this on a horizontal guide displaceable, a load receiving means which is mounted on a side slide, a height adjustable mounted on the mast and with the help of a lifting - And sink drive actuated side shift guide, which carries the side slide laterally movable, and a side shift drive and associated with actuators for the lifting and lowering operation, the mast pushing operation and the side shift operation electrical control device for the corresponding drives.
- the position of the side shifter is detected by an analog sensor whose position signal is given to the control device and the side shifter is automatically shifted by the control unit to a predetermined center position in which a collision with the radar arms is avoided.
- the invention has for its object to provide a truck with a limit switch, in which a lock can be safely and reliably automatically canceled.
- the truck according to the invention has a pair of longitudinally projecting radar arms.
- the truck is equipped with a longitudinally movable mast.
- a Zinkenverstell till is provided by which each load prong of a pair of load tines is displaceable transversely to the longitudinal direction of the truck independently of the respective other load tine.
- the load tines are jointly adjustable in height along the mast.
- the limit switch system is equipped with a control which prevents a collision of each of the load tines with the wheel arms.
- the limit switch system has a height sensor for at least one of the load tines, which detects a falling below a predetermined minimum height. If the load tine falls below the predetermined minimum height, the height sensor responds.
- the limit switch system is equipped with sensors that can detect a position of the load tines relative to the radar arms.
- the control of the limit switch system locks in a not fully advanced position of the mast all functions for moving the load tines when the predetermined minimum height is exceeded.
- a lowering function for the load tines to a height below the minimum height is released by the control if, for each load tine, a position on the side of the wheel arms has been detected by the corresponding sensors.
- the limit switch system according to the invention makes it possible to release locked hydraulic functions without additional operating procedures, so that the load tines can also be lowered to a height below the predetermined minimum height.
- According to the invention checks the Limit switch system, whether there is a risk of collision of the load tines with the radar arms.
- a load sensor is also provided which detects whether there is a load on the load tine.
- the control of the limit switch system is in this embodiment, a lowering function for the load tines to a height below the minimum height then free when the load sensor has also found that there is no load on the load tines. This ensures that, even if the load tines do not collide with the wheel arms, a received load does not collide with the wheel arms when the load tines are fully lowered and the mast is not in its maximum advanced position.
- the control of the limit switch system locks a mast thrust when the predetermined minimum height of the load tines is exceeded.
- the mast thrust is blocked when reaching or falling below the predetermined minimum height for the load tines, thereby preventing the mast is retracted to the vehicle.
- another feed of the mast is blocked. The locking of the mast thrust ensures that a collision of the load tines with the radar arms is not caused by the mast thrust.
- the control of the limit switch system releases the mast thrust, if a lowering function for the load tines is released to a height below the minimum height. By releasing the further lowering of the load tines is already ensured that the load tines are in a position that does not collide with the radar arms.
- the control of the limit switch system a lateral Adjustment of the load tines blocks if they have a height below the minimum height. In this way it can be ensured that if the sensors have detected that there is a danger of collision of the load tine with the wheel arms, the load tines are not adjusted laterally and thus collide with the wheel arms.
- Zinkenverstell In the Zinkenverstell founded there are basically two different variants.
- One variant relates to a Zinkenverstell noticed that allows lateral adjustment of the load tines only in the area between the radar arms and on this and a lateral adjustment outside the wheel arms does not allow.
- a second alternative embodiment of the Zinkenverstell allows an adjustment of the load tines in a region outside of the wheel arms. If the Zinkenverstell responded allows lateral adjustment of the load tine only within and above the wheel arms, so not in an area beyond the wheel arms, the sensors for detecting the position of the load tines are each not arranged outside the wheel arms and each have a magnetic switch. The load tines are equipped accordingly with magnets, each of the magnetic switch changes its switching state when the magnets sweep it laterally. In this embodiment, the magnetic switch changes its switching position when the load tine is inside the wheel arms. If the load tine is moved outwards again and is thus above the wheel arms, the corresponding magnetic switch changes its switching position.
- the sensors for detecting the position of the load tines relative to the radar arms are each equipped with a pair of magnetic switches.
- a pair of magnetic switches to the wheel arms is used in particular when the ZinkenverstellUNE allows lateral movement of the load tines inside and outside of the wheel arms.
- the load tines are each equipped with a magnet, wherein the magnetic switches each change their switching state when the magnet sweeps them laterally.
- the control of the limit switch system to evaluate the position of the magnetic switch to each fork to determine whether the fork is located between the Radarmen or outside of the wheel arms. It is so that at one position of the fork tine, which does not collide with the wheel, only one of the magnetic switch has been swept so that the switching state of both magnetic switch is readable, whether the fork is located above the radar.
- the magnetic switch in the Zinkenverstell est are arranged in pairs according to the position of the wheel arms such that a first magnetic switch changes its switching state when the load tine is adjusted from outside the side over the wheel, and a second magnetic switch changes its switching state when the Lastzinke from the area between the load tines is adjusted laterally over the Radarm.
- the arrangement of the magnetic switch on the Zinkenverstell est also allows to determine at any height on the Radarmen whether the forks are located above the arms or not.
- the control of the limit switch system detects a possible collision of a load tine with one of the wheel arms such that only one of two magnetic switches, which are assigned to the wheel arm, has changed its switching state. If both magnetic switches on a wheel arm have changed their switching state, the control system of the switch system can evaluate that the fork tine has completely swept over the wheel arm.
- Fig. 1 shows a reach truck 10 in a perspective view in which a left front wheel 11 can be seen.
- the reach truck 10 has a mast 12 with two extendable mast segments 13 (not shown).
- a load-receiving means 14 is mounted, which is adjustable in height to the mast 12.
- the load-receiving means 14 has two parallel arranged load tines 16, which in Fig. 1 are lowered outside of the wheel arms 18.
- the load-receiving means 14 is designed as a Zinkenverstell réelle 20, which allows the load tines 16 individually adjusted laterally, so that they can be lowered, for example, within the wheel arms 18 or outside of the wheel arms 18. The adjustment of the load tines in their lateral position allows, for example, to accommodate long goods during transport, and to support them by the load tines 16 spaced from each other.
- a height sensor 22 is provided laterally.
- the height sensor 22 is actuated by a corresponding trigger 24, which is arranged on the Zinkenverstell réelle on the side facing the mast 12 side.
- the height sensor 22 and its trigger 24 are arranged at a height to the vehicle above the ground, that the underside of the load tines 16 has the minimum distance to the ground and thus to the radar arms provided.
- Fig. 2 shows an enlarged view of the left front wheel arm 18 at a lowered load prong 16.
- the load tine 16 is moved by the Zinkenverstell réelle in its maximum outer position, in which the load tine 16 outside the radar 18 can be lowered.
- the Zinkenverstell réelle 20 has a trigger 24, which may be formed for example as a magnet and with the height sensor 22, which may be formed, for example, as a magnetic switch cooperates.
- a respective magnet 28 is arranged at the root of the load tines 16 a and 16 b. In a lateral adjustment of the load tines of the magnet 28 passes each one of the magnetic switch 26 ad.
- position of the load tine 16 a have the associated magnetic switch 26 a and 26 b respectively the switching position +. This means that the load tine 16 a is located above the wheel arms. If the load tine 16 a is moved to the left via the magnetic switch 26 a, then the switching state changes in -. This means the switches 26 a and 26 b have the switching state (-, +).
- This switching state indicates to the control of the limit switch system that the load tine 16 a is located outside the wheel arms. Likewise, the switching state of the magnetic switch 26 b changes in the case of a movement inwards toward the load tine 16 b, so that the switching state (+, -) is present for the control of the limit switch system. This switching state also indicates to the controller that there is no collision of the load tine 16 a with the wheel arm.
- the controller recognizes that an error has occurred. In this case, the controller can block a lowering of the load tines below the minimum height.
- the magnetic switches 26 a and 26 d which in their switching state (+, +) as in Fig. 2 shown, the control of the limit switch system indicate that the load tine 16 b is located above the wheel arms.
- the switching state (-, +) of the magnetic switch 26 c, 26 d indicates that the load tine 16 b is located within the wheel arms, while the switching state (+, -) indicates that the load tine 16 b is outside the wheel arms.
- the Endschaltstrom invention makes it possible for a Zinkenverstell pleased cancel a shutdown of the lowering function, if a collision with the Radarmen is excluded. In this case, a collision with the radar arms is checked individually for each load tine 16. In addition, a sensor can ensure that there is no load on the load tines. If there is no load tine in the collision area with the wheel arm, a blocking of the lowering operation is canceled.
- Fig. 4 shows in a flow chart the individual steps performed by the controller.
- lifting and tilting is generally allowed and permitted. If it is determined in step 32 that the load bearing is above the safety height, all hydraulic functions are released. In this case, hydraulic functions are released in step 34 for lowering, pushing forward and backward of the mast for a side thrust of both load tines and for individual tine adjustment. If the condition in step 32 is not met, that is, the load bearing is not above the safety height, it is queried in a subsequent step 36, if the mast is in its fully advanced position. If the query 36 that the mast is fully advanced, so in step 38, the hydraulic function is disabled for pushing back the mast. All other hydraulic functions of the mast are released in step 38.
- step 40 If it is determined in step 36 that the mast is not fully advanced, it is checked in step 40, as explained above, whether the load tines are in the collision area of the wheel arms. In this case, the hydraulic functions for lowering, forward and backward pushing of the mast, side sliding and tine adjustment are inhibited in step 42. Are the load tines not in the Collision area of the wheel arms, it is checked in step 44, whether a load is on the forks. If there is a load, the said hydraulic functions are likewise blocked in step 42. If, however, it is determined in step 44 that there is no load on the forks, a lowering of the load forks and a displacement of the lifting mast is automatically released back and forth in step 46.
- Step 46 thus presupposes that the load tines 16a, 16b are neither in the collision area with the wheel arms 18 nor is there a load on the load tines.

Description
Die vorliegende Erfindung betrifft ein Flurförderzeug mit einem Paar von in Längsrichtung vorstehenden Radarmen, einem in Längsrichtung verschiebbaren Hubgerüst, einer Zinkenverstelleinrichtung und einem Paar von Lastzinken, die gemeinsam in ihrer Höhe entlang dem Hubgerüst und einzeln quer zur Längsrichtung verstellbar sind. Insbesondere betrifft die Erfindung einen Schubmaststapler, der mit einem Zinkenverstellgerät zum seitlichen Verstellen der einzelnen Lastzinken ausgestattet ist.The present invention relates to an industrial truck with a pair of longitudinally projecting wheel arms, a longitudinally displaceable mast, a Zinkenverstelleinrichtung and a pair of load tines, which are adjustable in height along the mast and individually transversely to the longitudinal direction. In particular, the invention relates to a reach truck, which is equipped with a Zinkenverstellgerät for laterally adjusting the individual load tines.
Für eine Endschalteranlage ist es bekannt, bei einem an dem Mast vorgesehenen Seitenschieber die Mittelstellung eines Gabelträgers und eine Sicherheitshöhe der Gabeln zu erfassen. Die bekannte Endschalteranlage sieht vor, ein Heben und Neigen der Gabel grundsätzlich freizugeben, jedoch wenn sich der Gabelträger unterhalb der Sicherheitshöhe von 500 bis 600 mm befindet, sämtliche anderen Hydraulikfunktionen abzuschalten. Ist ferner der Mast vollständig vorgeschoben und befindet sich die Gabel unterhalb der Sicherheitshöhe, wird ein Zurückziehen des Hubgerüsts durch die bekannte Endschalteranlage gesperrt. Die übrigen Funktionen sind dagegen freigeschaltet. Bei einem nicht vollständig vorgeschobenen Hubgerüst und Gabeln unterhalb der Sicherheitshöhe sperrt die bekannte Endschalteranlage die Funktionen für ein weiteres Senken der Gabel, den Mastschub, den Seitenschub und hydraulische Zusatzfunktionen wie beispielsweise eine seitliche Zinkenverstellung. Bei der bekannten Endschalteranlage wird bei Erreichen der Mittelposition des Gabelträgers automatisch die Hydraulikfunktion für den Mastschub und das Senken freigegeben, während die weiteren Hydraulikfunktionen gesperrt bleiben.For a limit switch system, it is known to detect the center position of a fork carriage and a safety height of the forks in a side slide provided on the mast. The well-known limit switch system provides to release a lifting and tilting of the fork in principle, but if the fork carriage is below the safety height of 500 to 600 mm, to turn off all other hydraulic functions. Furthermore, if the mast is fully advanced and the fork is below the safety height, retraction of the mast is blocked by the known limit switch system. The other functions are unlocked. In a not fully advanced mast and forks below the safety height locks the known limit switch the functions for further lowering the fork, the mast, the side thrust and additional hydraulic functions such as a lateral fork adjustment. In the known limit switch system, the hydraulic function for the mast thrust and the lowering is automatically released on reaching the central position of the fork carriage, while the other hydraulic functions remain locked.
Bei einer weiteren Endschalteranlage ist es bekannt, dass der Fahrer durch manuelle Betätigung eines zusätzlichen Überbrückungstasters gesperrte Funktionen freigeben kann. Hierbei ist vorgesehen, dass ein Heben und Neigen grundsätzlich freigeben ist sowie sonstige Hydraulikfunktionen, wenn der Gabelträger eine Mindesthöhe von 500 bis 600 mm oder mehr besitzt. Ist der Mast vollständig vorgeschoben und befinden sich die Gabeln unterhalb der Sicherheitshöhe, wird das Zurückziehen des Hubgerüsts gesperrt, während alle übrigen Funktionen weiterhin freigegeben sind. Ist das Hubgerüst nicht vollständig vorgeschoben und befinden sich die Gabeln unterhalb der Sicherheitshöhe, sind ein weiteres Senken der Gabeln, ein Mastschub, ein Seitenschub und hydraulische Zusatzfunktionen wie beispielsweise eine Zinkenverstellung gesperrt. Eine Aufhebung der Sperrung erfolgt über den zusätzlichen Überbrückungstaster. So können gesperrte Hydraulikfunktionen freigegeben werden, solange der Taster betätigt ist. Bei der bekannten Endschalteranlage erfolgt eine Aufhebung der Sperrung ohne Betätigung des Überbrückungstasters, wenn das zugehörige Betätigungselement zu der jeweiligen Funktion einen Nulldurchgang erfährt. In diesem Fall wird dann die Sperrung der entsprechenden Funktion aufgehoben und mit geringerer Geschwindigkeit fortgesetzt.In another limit switch system, it is known that the driver can release locked functions by manual operation of an additional bridging button. It is provided that a lifting and tilting is basically release and other hydraulic functions when the fork carriage has a minimum height of 500 to 600 mm or more. With the mast fully extended and the forks below the safety height, mast retraction is disabled while all other functions remain enabled. If the mast is not completely advanced and the forks are below the safety height, further lowering of the forks, a mast thrust, a side thrust and additional hydraulic functions such as a fork adjustment are blocked. The blocking is canceled via the additional bridging button. Locked hydraulic functions can be enabled as long as the button is pressed. In the known limit switch system is a lifting of the lock without actuation of the lock-up button when the associated actuator undergoes a zero crossing to the respective function. In this case, the blocking of the corresponding function is then canceled and continued at a lower speed.
Aus
Der Erfindung liegt die Aufgabe zugrunde, ein Flurförderzeug mit einer Endschalteranlage bereitzustellen, bei dem eine Sperrung sicher und zuverlässig automatisch aufgehoben werden kann.The invention has for its object to provide a truck with a limit switch, in which a lock can be safely and reliably automatically canceled.
Erfindungsgemäß wird die Aufgabe durch ein Flurförderzeug mit den Merkmalen aus Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen bilden den Gegenstand der Unteransprüche.According to the invention the object is achieved by an industrial truck with the features of claim 1. Advantageous embodiments form the subject of the dependent claims.
Das erfindungsgemäße Flurförderzeug besitzt ein Paar von in Längsrichtung vorstehenden Radarmen. Das Flurförderzeug ist mit einem in Längsrichtung verschiebbaren Hubgerüst ausgestattet. Ferner ist eine Zinkenverstelleinrichtung vorgesehen, durch die jede Lastzinke von einem Paar von Lastzinken unabhängig von der jeweils anderen Lastzinke quer zur Längsrichtung des Flurförderzeugs verschiebbar ist. Die Lastzinken sind gemeinsam in ihrer Höhe entlang dem Hubgerüst verstellbar. Erfindungsgemäß ist die Endschalteranlage mit einer Steuerung ausgestattet, die eine Kollision jeder der Lastzinken mit den Radarmen verhindert. Die Endschalteranlage besitzt einen Höhensensor für mindestens eine der Lastzinken, der ein Unterschreiten einer vorbestimmten Mindesthöhe erfasst. Unterschreitet die Lastzinke die vorbestimmte Mindesthöhe, so spricht der Höhensensor an. Ferner ist die Endschalteranlage mit Sensoren ausgestattet, die eine Position der Lastzinken relativ zu den Radarmen erfassen können. Die Steuerung der Endschalteranlage sperrt in einer nicht vollständig vorgeschobenen Position des Hubgerüsts sämtliche Funktionen zur Bewegung der Lastzinken, wenn die vorbestimmte Mindesthöhe unterschritten wird. Eine Senkfunktion für die Lastzinken auf eine Höhe unterhalb der Mindesthöhe wird von der Steuerung freigegeben, wenn für jede Lastzinke eine Position seitlich der Radarme von den entsprechenden Sensoren erfasst wurde. Die erfindungsgemäße Endschalteranlage erlaubt es, ohne zusätzliche Bedienvorgänge gesperrte Hydraulikfunktionen freizugeben, so dass die Lastzinken auch auf eine Höhe unterhalb der vorbestimmten Mindesthöhe abgesenkt werden können. Erfindungsgemäß prüft hierzu die Endschalteranlage, ob die Gefahr einer Kollision der Lastzinken mit den Radarmen besteht.The truck according to the invention has a pair of longitudinally projecting radar arms. The truck is equipped with a longitudinally movable mast. Further, a Zinkenverstelleinrichtung is provided by which each load prong of a pair of load tines is displaceable transversely to the longitudinal direction of the truck independently of the respective other load tine. The load tines are jointly adjustable in height along the mast. According to the invention, the limit switch system is equipped with a control which prevents a collision of each of the load tines with the wheel arms. The limit switch system has a height sensor for at least one of the load tines, which detects a falling below a predetermined minimum height. If the load tine falls below the predetermined minimum height, the height sensor responds. Furthermore, the limit switch system is equipped with sensors that can detect a position of the load tines relative to the radar arms. The control of the limit switch system locks in a not fully advanced position of the mast all functions for moving the load tines when the predetermined minimum height is exceeded. A lowering function for the load tines to a height below the minimum height is released by the control if, for each load tine, a position on the side of the wheel arms has been detected by the corresponding sensors. The limit switch system according to the invention makes it possible to release locked hydraulic functions without additional operating procedures, so that the load tines can also be lowered to a height below the predetermined minimum height. According to the invention checks the Limit switch system, whether there is a risk of collision of the load tines with the radar arms.
In einer bevorzugten Ausgestaltung ist ferner ein Lastsensor vorgesehen, der erfasst, ob sich auf dem Lastzinken eine Last befindet. Die Steuerung der Endschalteranlage gibt in dieser Ausgestaltung eine Senkfunktion für die Lastzinken auf eine Höhe unterhalb der Mindesthöhe dann frei, wenn der Lastsensor zusätzlich festgestellt hat, dass sich keine Last auf den Lastzinken befindet. Hierdurch wird sichergestellt, dass, selbst wenn die Lastzinken nicht mit den Radarmen kollidieren, auch eine aufgenommene Last nicht mit den Radarmen kollidiert, wenn die Lastzinken vollständig abgesenkt werden und das Hubgerüst nicht in seiner maximal vorgeschobenen Position ist.In a preferred embodiment, a load sensor is also provided which detects whether there is a load on the load tine. The control of the limit switch system is in this embodiment, a lowering function for the load tines to a height below the minimum height then free when the load sensor has also found that there is no load on the load tines. This ensures that, even if the load tines do not collide with the wheel arms, a received load does not collide with the wheel arms when the load tines are fully lowered and the mast is not in its maximum advanced position.
In einer weiteren bevorzugten Ausgestaltung sperrt die Steuerung der Endschalteranlage einen Mastschub, wenn die vorbestimmte Mindesthöhe der Lastzinken unterschritten wird. Bei dieser Ausgestaltung wird also bei einem Erreichen oder Unterschreiten der vorbestimmten Mindesthöhe für die Lastzinken der Mastschub gesperrt, wodurch verhindert wird, dass der Mast zum Fahrzeug zurückgezogen wird. Zudem ist ein weiterer Vorschub des Mastes gesperrt. Das Sperren des Mastschubs stellt sicher, dass eine Kollision der Lastzinken mit den Radarmen nicht durch den Mastschub verursacht wird.In a further preferred embodiment, the control of the limit switch system locks a mast thrust when the predetermined minimum height of the load tines is exceeded. In this embodiment, therefore, the mast thrust is blocked when reaching or falling below the predetermined minimum height for the load tines, thereby preventing the mast is retracted to the vehicle. In addition, another feed of the mast is blocked. The locking of the mast thrust ensures that a collision of the load tines with the radar arms is not caused by the mast thrust.
Bei einer bevorzugten Weiterbildung gibt die Steuerung der Endschalteranlage den Mastschub frei, wenn eine Senkfunktion für die Lastzinken auf eine Höhe unterhalb der Mindesthöhe freigegeben ist. Durch die Freigabe des weiteren Absenkens der Lastzinken ist bereits sichergestellt, dass sich die Lastzinken in einer Position befinden, die nicht mit den Radarmen kollidiert.In a preferred embodiment, the control of the limit switch system releases the mast thrust, if a lowering function for the load tines is released to a height below the minimum height. By releasing the further lowering of the load tines is already ensured that the load tines are in a position that does not collide with the radar arms.
Bei dem erfindungsgemäßen Flurförderzeug ist bei einer bevorzugten Weiterbildung ferner vorgesehen, dass die Steuerung der Endschalteranlage eine seitliche Verstellung der Lastzinken sperrt, wenn diese eine Höhe unterhalb der Mindesthöhe aufweisen. Auf diese Weise kann sichergestellt werden, dass wenn die Sensoren erkannt haben, dass eine Kollisionsgefahr des Lastzinkens mit den Radarmen vorliegt, die Lastzinken nicht seitlich verstellt werden und so mit den Radarmen kollidieren.In the truck according to the invention is further provided in a preferred development that the control of the limit switch system a lateral Adjustment of the load tines blocks if they have a height below the minimum height. In this way it can be ensured that if the sensors have detected that there is a danger of collision of the load tine with the wheel arms, the load tines are not adjusted laterally and thus collide with the wheel arms.
Bei der Zinkenverstelleinrichtung gibt es grundsätzlich zwei unterschiedliche Varianten. Die eine Variante betrifft eine Zinkenverstelleinrichtung, die ein seitliches Verstellen der Lastzinken nur in dem Bereich zwischen den Radarmen und über diesen zulässt und ein seitliches Verstellen außerhalb der Radarme nicht zulässt. Eine zweite alternative Ausgestaltung der Zinkenverstelleinrichtung erlaubt eine Verstellung der Lastzinken auch in einem Bereich außerhalb der Radarme. Wenn die Zinkenverstelleinrichtung eine seitliche Verstellung der Lastzinke nur innerhalb und oberhalb der Radarme, also nicht in einem Bereich über die Radarme hinaus, zulässt, sind die Sensoren zur Erfassung der Position der Lastzinken jeweils nicht außerhalb der Radarme angeordnet und weisen jeweils einen Magnetschalter auf. Die Lastzinken sind entsprechend mit Magneten ausgestattet, wobei jeder der Magnetschalter seinen Schaltzustand ändert, wenn die Magneten diesen seitlich überstreichen. Bei dieser Ausgestaltung wechselt der Magnetschalter seine Schaltposition, wenn sich die Lastzinke innerhalb der Radarme befindet. Wird die Lastzinke wieder nach außen verfahren und befindet sich somit oberhalb der Radarme, wechselt der entsprechende Magnetschalter seine Schaltposition.In the Zinkenverstelleinrichtung there are basically two different variants. One variant relates to a Zinkenverstelleinrichtung that allows lateral adjustment of the load tines only in the area between the radar arms and on this and a lateral adjustment outside the wheel arms does not allow. A second alternative embodiment of the Zinkenverstelleinrichtung allows an adjustment of the load tines in a region outside of the wheel arms. If the Zinkenverstelleinrichtung allows lateral adjustment of the load tine only within and above the wheel arms, so not in an area beyond the wheel arms, the sensors for detecting the position of the load tines are each not arranged outside the wheel arms and each have a magnetic switch. The load tines are equipped accordingly with magnets, each of the magnetic switch changes its switching state when the magnets sweep it laterally. In this embodiment, the magnetic switch changes its switching position when the load tine is inside the wheel arms. If the load tine is moved outwards again and is thus above the wheel arms, the corresponding magnetic switch changes its switching position.
In einer bevorzugten Ausgestaltung sind die Sensoren zur Erfassung der Position der Lastzinken relativ zu den Radarmen jeweils mit einem Paar von Magnetschaltern ausgestattet. Ein Paar von Magnetschaltern zu den Radarmen wird insbesondere dann eingesetzt, wenn die Zinkenverstelleinrichtung eine seitliche Bewegung der Lastzinken innerhalb und außerhalb der Radarme zulässt. Ferner sind die Lastzinken jeweils mit einem Magneten ausgestattet, wobei die Magnetschalter jeweils ihren Schaltzustand ändern, wenn der Magnet diese seitlich überstreicht. Auf diese Weise kann bevorzugt die Steuerung der Endschalteranlage die Stellung der Magnetschalter zu jeder Gabelzinke dahingehend auswerten, ob die Gabelzinke sich zwischen den Radarmen oder außerhalb der Radarme befindet. Hierbei ist es so, dass bei einer Stellung der Gabelzinke, die nicht mit dem Radarm kollidiert, nur einer der Magnetschalter überstrichen wurde, so dass am Schaltzustand beider Magnetschalter ablesbar ist, ob die Gabelzinke sich oberhalb des Radarms befindet.In a preferred embodiment, the sensors for detecting the position of the load tines relative to the radar arms are each equipped with a pair of magnetic switches. A pair of magnetic switches to the wheel arms is used in particular when the Zinkenverstelleinrichtung allows lateral movement of the load tines inside and outside of the wheel arms. Furthermore, the load tines are each equipped with a magnet, wherein the magnetic switches each change their switching state when the magnet sweeps them laterally. In this way Preferably, the control of the limit switch system to evaluate the position of the magnetic switch to each fork to determine whether the fork is located between the Radarmen or outside of the wheel arms. It is so that at one position of the fork tine, which does not collide with the wheel, only one of the magnetic switch has been swept so that the switching state of both magnetic switch is readable, whether the fork is located above the radar.
Bei einer bevorzugten Ausgestaltung sind die Magnetschalter in der Zinkenverstelleinrichtung jeweils paarweise entsprechend der Position der Radarme derart angeordnet, dass ein erster Magnetschalter seinen Schaltzustand wechselt, wenn die Lastzinke von außerhalb seitlich über den Radarm verstellt wird, und ein zweiter Magnetschalter seinen Schaltzustand wechselt, wenn die Lastzinke aus dem Bereich zwischen den Lastzinken seitlich über den Radarm verstellt wird. Die Anordnung der Magnetschalter an der Zinkenverstelleinrichtung erlaubt es auch, in einer beliebigen Höhe über den Radarmen festzustellen, ob die Gabelzinken sich oberhalb der Radarme befmden oder nicht.In a preferred embodiment, the magnetic switch in the Zinkenverstelleinrichtung are arranged in pairs according to the position of the wheel arms such that a first magnetic switch changes its switching state when the load tine is adjusted from outside the side over the wheel, and a second magnetic switch changes its switching state when the Lastzinke from the area between the load tines is adjusted laterally over the Radarm. The arrangement of the magnetic switch on the Zinkenverstelleinrichtung also allows to determine at any height on the Radarmen whether the forks are located above the arms or not.
Bei einer bevorzugten Weiterbildung erkennt die Steuerung der Endschalteranlage eine mögliche Kollision einer Lastzinke mit einem der Radarme derart, dass nur einer von zwei Magnetschaltern, die dem Radarm zugeordnet sind, seinen Schaltzustand gewechselt hat. Wenn beide Magnetschalter an einem Radarm ihren Schaltzustand gewechselt haben, kann die Steuerung der Schalteranlage auswerten, dass die Gabelzinke den Radarm vollständig überstrichen hat.In a preferred embodiment, the control of the limit switch system detects a possible collision of a load tine with one of the wheel arms such that only one of two magnetic switches, which are assigned to the wheel arm, has changed its switching state. If both magnetic switches on a wheel arm have changed their switching state, the control system of the switch system can evaluate that the fork tine has completely swept over the wheel arm.

An dem Hubgerüst 12 ist seitlich ein Höhensensor 22 vorgesehen. Der Höhensensor 22 wird durch einen entsprechenden Auslöser 24 betätigt, der an dem Zinkenverstellgerät auf der zum Hubgerüst 12 weisenden Seite angeordnet ist. Der Höhensensor 22 und sein Auslöser 24 sind dabei in einer Höhe an dem Fahrzeug über dem Boden angeordnet, dass die Unterseite der Lastzinken 16 den vorgesehenen Mindestabstand zum Untergrund und damit zu den Radarmen besitzt.On the mast 12, a

Sollte an den Schaltern 26 a und 26 b der Schaltzustand (-, -) vorliegen, so erkennt die Steuerung, dass ein Fehler aufgetreten ist. In diesem Fall kann die Steuerung ein Absenken der Lastzinken unter die Mindesthöhe sperren. Ebenso verhält es sich bei den Magnetschaltern 26 a und 26 d, die in ihrem Schaltzustand (+, +) wie in
Bei einer Zinkenverstelleinrichtung, die nur ein Verschieben der Lastzinken 16a und 16b in dem Bereich innerhalb der Radarme zulässt, können die Magnetschalter 26a und 26d entfallen.In a Zinkenverstelleinrichtung, which allows only a displacement of the
Die erfindungsgemäße Endschaltanlage erlaubt es, für eine Zinkenverstelleinrichtung eine Abschaltung der Senkfunktion aufzuheben, wenn eine Kollision mit den Radarmen ausgeschlossen ist. Hierbei wird für jede Lastzinke 16 einzeln eine Kollision mit den Radarmen überprüft. Zusätzlich kann eine Sensorik sicherstellen, dass sich keine Last auf den Lastzinken befindet. Wenn sich keine Lastzinke im Kollisionsbereich mit dem Radarm befindet, wird eine Sperrung des Senkbetriebs aufgehoben.The Endschaltanlage invention makes it possible for a Zinkenverstelleinrichtung cancel a shutdown of the lowering function, if a collision with the Radarmen is excluded. In this case, a collision with the radar arms is checked individually for each
