Description

Die Erfindung bezieht sich auf eine Hubvorrichtung an einer Krananlage zum wahlweisen Heben und Senken eines Hängetasters, der zum Steuern der Krananlage und/oder von Hebezeugen vorgesehen und über ein Hubseil und eine Steuerleitung mit der Krananlage verbunden ist, wie diese beispielsweise aus der DD-A- 93 414 bekannt ist.The invention relates to a lifting device on a crane system for selectively lifting and lowering a pendant switch, which is provided for controlling the crane system and / or hoists and is connected to the crane system via a lifting cable and a control line, such as this from the DD-A - 93 414 is known.

Stand der Technik:State of the art:

Krananlagen werden über Schaltelemente betrieben, die in einem Hängetaster angeordnet sind. Der Hängetaster ist über ein Hubseil und eine Steuerleitung mit der Krananlage verbunden - vgl. DE-A1-39 26 935 -. Soll dieselbe Krananlage durch eine an sich bekannte Fernsteuerung - vgl. DE-U- 89 15 382 - oder von einer anderen Bedienstelle gesteuert werden, so wird der Hängetaster durch eine an der Krananlage vorgesehene Hubvorrichtung angehoben - vgl. DD-A- 93 414 -. Die Hubvorrichtung wird außerdem dann eingesetzt, wenn der Arbeitsbereich der Krananlage auf unterschiedlichen Ebenen liegt. In diesem Fall kann der Hängetaster in verschiedenen Positionen gebracht werden. Ein weiterer Einsatzfall ist dann gegeben, wenn innerhalb des Arbeitsbereichs der Krananlage Hindernisse vorhanden sind, über die der Hängetaster gehoben werden muß.Crane systems are operated via switching elements that are arranged in a pendant control. The pendant control is connected to the crane system via a hoist rope and a control line - cf. DE-A1-39 26 935 -. If the same crane system is to be operated by a remote control known per se - cf. DE-U- 89 15 382 - or controlled by another control point, the pendant control is raised by a lifting device provided on the crane system - cf. DD-A-93 414 -. The lifting device is also used when the working area of the crane system is on different levels. In this case the pendant can be moved to different positions. Another application is when there are obstacles within the working area of the crane system, over which the pendant switch must be lifted.

Bekannte Hubvorrichtungen für Hängetaster fahren, gestartet über ein Steuersignal, in eine durch Endschalter vorgegebene Position. Das Steuersignal kann durch einen Schalter, der sich auf dem Hängetaster selbst befindet, oder durch einen an einer anderen Stelle fest installierten Schalter gegeben werden.Known lifting devices for pendant switches move, started via a control signal, into a position specified by limit switches. The control signal can be given by a switch, which is located on the pendant control itself, or by a switch permanently installed at another point.

Nachteilig bei den Anordnungen der genannten Art ist die ortsfeste Bedienung der Hubvorrichtung für den Hängetaster. Ist zum Beispiel der Schalter zum Heben des Hängetasters in seinem Gehäuse selbst installiert, kann sich folgende Situation ergeben: Zum Arbeiten auf einer Hallenebene, die an die Hallenebene angrenzt, auf der bisher gearbeitet wurde, und höher gelegen ist, wird der Hängetaster angehoben. Ist die Krananlage jedoch nicht nahe genug an der höher gelegenen Hallenebene positioniert, kann der Hängetaster von dort nicht erreicht werden.A disadvantage of the arrangements of the type mentioned is the fixed operation of the lifting device for the pendant control. If, for example, the switch for lifting the pendant switch is installed in its housing, the following situation can arise: To work on a hall level that is adjacent to the hall level on which work was carried out and is located higher, the pendant switch is raised. However, if the crane system is not positioned close enough to the higher hall level, the pendant control cannot be reached from there.

Darstellung der Erfindung:Presentation of the invention:

Hier will die Erfindung Abhilfe schaffen. Der Erfindung liegt die Aufgabe zugrunde, eine Hubvorrichtung zu schaffen, die unabhängig von der Position des Hängetasters steuerbar ist.The invention seeks to remedy this. The invention has for its object to provide a lifting device that is controllable regardless of the position of the pendant button.

Gemäß der Erfindung wird die genannte Aufgabe dadurch gelöst, daß in der Hubvorrichtung ein Empfänger vorgesehen ist, über den die Hubvorrichtung steuerbar ist und der seinerseits über mindestens einen ortsunabhängigen Sender drahtlos steuerbar ist.According to the invention, the above object is achieved in that a receiver is provided in the lifting device, via which the lifting device can be controlled and which in turn can be controlled wirelessly via at least one location-independent transmitter.

Mittels der drahtlosen Steuerung für die Hubvorrichtung des Hängetasters ist es möglich, diesen in jeder Position ohne zusätzliche Hilfsmittel zu heben und zu senken. Dabei können kostengünstige drahtlose Steuerungen verwendet werden. Der Empfänger ist durch einen oder mehrere Sender, insbesondere Handsender, ortsunabhängig steuerbar.Using the wireless control for the lifting device of the pendant control, it is possible to raise and lower it in any position without additional aids. Inexpensive wireless controls can be used. The receiver can be controlled regardless of location by one or more transmitters, in particular hand-held transmitters.
