The invention relates to a lifting device for lifting, transporting and depositing loads with a housing having two lifting arms which delimit between them at least one side open load receiving space and each having an abutment against which a locking member in its latched position is supported with the respective abutment, which is guided in its dissolved position by means of an actuating device about a pivot axis rotatably movable.

Such a generic lifting device is for example off DE 20 2006 019 490 U1 known. The known lifting device is a load hanger for lifting a load, with at least one, hinged at a free end of the load hanger pawl as a locking part, which is in the closed state for lifting a load in the region of a load-receiving zone of the load yoke and is pivotable such that a load-receiving means is detachable from the load bar. The pawl includes two on one leg or a lifting arm of the load strap successively hinged slats, which extend in the closed state largely parallel to each other and across the opening of the load yoke and allow a load handling device, such as a rope or a chain, passed over this is to pick up a load. The catch part forming the catch is supported in its latched position, each with an abutment formed by the free ends of the lifting arms of the load yoke, at this. With regard to the safety of locking or locking the locking part in the latched position, especially against unintentional opening of the latch with the risk of dangerous falling out of a load from the lifting device, the known solution leaves nothing to be desired.

The invention has as its object to increase the reliability of a lifting device for lifting, transporting and depositing loads to the effect that accidental opening of the locking member from the latched or locked position is effectively avoided.

This object is achieved by a lifting device with the features of claim 1 in its entirety. Advantageous embodiments of the invention are the subject of the dependent claims.

A lifting device according to the invention is characterized in that the locking part is provided with a control part, which in its actuated or unactuated state, the locking member in a translational movement transversely to the pivot axis of the same out of or in latching contact with the respective abutment. By the control part, the reliability of the lifting device is increased to the effect that the latching of the locking member takes place in a different from the rotational opening or closing movement, translational movement. The associated technical design of the lifting device prevents an opening movement of the latched locking part, since this must first be transferred from the latched position in translational motion in the released position to be opened from this position in a rotational movement. The control part is a locking mechanism for the locking of the locking part, which connects the two lifting arms bridge-like manner in contact with the abutments and thus closes the open side of the load receiving space. The force for the translatory movement the locking part is applied via the control part and in particular via a load acting on the locking part.

In a preferred embodiment of the lifting device according to the invention, the locking part at its free end on a locking lug which engages in the locked state in the wedge-shaped abutment on a lifting arm and that at the free end opposite end of the locking part, a further locking lug is formed, which is latched Condition is in abutment with the abutment on the other lifting arm, which is cylindrical or wedge-shaped. In particular, in an embodiment of two wedge-shaped abutments, in which a preferably also wedge-shaped locking lug engages from above, a completely secure latching respectively locking between the two lifting arms and the locking part is achieved.

In a preferred embodiment of the lifting device according to the invention, the locking part and the control part are connected to each other via a web portion such that at least in the latched position of the locking part a receiving space for a load-receiving means is formed as a subspace of the load receiving space. Typically, locking and web part and control and web part are each at a right angle to each other, so that the composite of locking, control and web part forms a U-shape. In a rotational movement of the locking part from the open to the closed position, the component comprising latching, control and web part is pivoted into the load receiving space such that at least the locking part, preferably locking and control part, abuts against the web part opposite lifting arm. The locking part, the web part, the control part and the at least one lifting arm form the sides of the receiving space. By locking the locking part of the abutments, which are preferably formed in the region of the free end of the respective lifting arm, the position of the composite of locking, control and web part is fixed and the position of a in the receiving space recorded load-receiving means, such as a rope, a chain or a fixedly attached to the load eyebolt.

In a preferred embodiment of the lifting device according to the invention, the locking part, the control part and the web part perpendicular to each other forms a component with the receiving space.

Particularly preferably, the load-receiving space delimited by the lifting arms has a substantially rectangular cross-sectional shape. This results in the advantage of a structurally simple construction of the lifting device, since at least in a portion of the mutually parallel lifting arms, the transverse thereto arranged locking part is translationally movable. For this purpose, a recess or a guide slot is preferably formed on at least one lifting arm on the receiving space associated inner surface, in which engage the free end of the locking part and can be moved in the direction of the abutment. Conveniently, the locking part in a lifting arm associated with a housing portion is pivotable and moved out of the load receiving space.

In a further preferred embodiment of the lifting device according to the invention, the preferably bar or web-like locking part in the region of the free end of the respective lifting arm at the same time in abutment with the respective abutment can be brought. A bar-shaped or ridge-like locking part represents a particularly suitable for the use of the lifting device plane contact surface for a load handling device, such as a rope or a chain, by the arrangement of the abutment in the region of the free end of the respective lifting arm is the largest possible receiving space for a Load receiving means formed as a subspace of the laterally limited by the lifting arms load receiving space. The respective abutment is optimized to meet requirements as a receptacle, latching nose, molding or the like configured.

It is also advantageous that the abutments are arranged in each case one, preferably in a common, aligned perpendicular to the translational movement of the locking part level and formed in its shape corresponding to the locking part. This results in the advantage that the abutment unhindered in a translational movement of the locking member come into contact with this and form a support for the latched locking part. The example cylindrical or wedge-shaped abutment are expediently designed counterpart to the locking part, wherein the latching part is provided a corresponding locking lug or recess.

In a preferred embodiment of the invention, a preferably acting on the control part restoring device, preferably with a spring element, such as a compression spring provided, which causes a translational return movement of the locking part from the latched position to the released position. Due to the automatic, caused by the return device provision of the locking part a user-friendly, easy handling of the lifting device is ensured. Typically, the restoring device is arranged in a housing part adjoining the control part, particularly preferably in the region of the pivot axis for latching and control part.

In a further preferred embodiment of the lifting device according to the invention the pivot axis for the rotational movement is provided in the region of the housing side, facing away from the open end of the load receiving space, and in particular the control part is arranged on the pivot axis and movable via the actuating device. This results in the advantage of a particularly compact construction of the lifting device, because the control part for opening, closing and locking of the load receiving space and the associated actuating device are arranged adjacent to each other and space-saving in the housing of the lifting device. The control part is typically designed bar or web-like, wherein the pivot axis is particularly preferably arranged centrally. The actuating device usually engages in an end region of the control part, particularly preferably in the connection region of web and control part, on the control part.

In a further preferred embodiment of the lifting device according to the invention the restoring device is arranged in the region of the pivot axis arranged preferably centrally on the control part such that the restoring direction changes in accordance with the pivot position of the control part and a translational return of the locking part is effected only in the correct position of the control part. This is achieved in particular by the fact that the restoring device is not fixed to the housing but is fixedly arranged on the pivotable control part.

It is also advantageous that the actuating device for the locking part which preferably acts on the control part comprises an operating element for a manual actuation and / or a motor, preferably a battery-operated electric motor, for an automatic actuation. By example, designed as a control lever operating element results in a simple, reliable handling of the lifting device, which is opened as needed to bring in or take out a lifting device and closed again for the load operation or storage of the lifting device. For a reliable operation of the lifting device in load operation, the two-point support of the locking part on the abutments in conjunction with the force applied via the load-receiving means on the locking part force is essential.

In a further preferred embodiment of the lifting device according to the invention a preferably acting on the control part further restoring device, preferably provided with a resilient element, which causes a rotational return movement of the locking part from the access to the load receiving space releasing position back into a load receiving space occluding position. It is understood that the locking part connected to the control part via the web part releases and closes the receiving space for the load receiving part in a corresponding manner. Typically, the further restoring device is arranged stationarily on the housing of the lifting device and, with particular preference, engages in the region of the control part on which the actuating device also engages.

The further restoring device is particularly preferably arranged outside the region of the pivot axis, which is preferably arranged centrally on the control part, such that a rotational return of the locking part is effected independently of the pivoting position of the control part. In this way, the force required for provision force is applied particularly easily to the control and locking part.

In a further preferred embodiment of the invention, an actuating part having the actuating device and the control part and further a carrier part adjoins a load-receiving part of the housing having the lifting arms, and in particular the carrier part comprises a receiving device for the lifting device. In the load-receiving part of the housing typically a lifting arm is widened or connects to a corresponding housing part, in which the locking part, in particular in conjunction with the web part and control part, is pivotable into.

The central control part for the movable components and the actuation and return mechanisms acting on the latter are arranged in the actuating part of the housing, which typically represents a central part of the housing. The carrier part which particularly preferably adjoins the actuating part has, in particular, the function of enabling a reception of the lifting device, for example via a retaining ring. Viewed as a whole, the housing is composed of carrier part, operating part and fork-like load receiving part. In general, the lifting device with the housing and the components arranged therein as well as the receiving device has a flat shape.

Advantageously, the motor for the actuator is arranged on the carrier part of the housing, preferably attached to the outside. In this way, no space for the motor is required in the load-receiving and operating part of the housing. In general, the motor is connected via a cable with the pivotally mounted control part. The arrangement on the outside of the housing or of the carrier part has the advantage that the motor is accessible in a simple manner for maintenance or repair purposes and can not be arranged in the housing of the lifting device for reasons of space size.

In the presentation of the Fig. 1a to 1d the lifting arms 14a, 14b are directed downwards and opposite to each other a receiving device 16 is arranged at the top of the housing 12. This corresponds to the extent of the use position of the lifting device 10 when lifting, transporting and depositing loads. The receiving device 16 is designed as a vertically parallel to the housing 12 aligned retaining ring and is penetrated for example by a crane hook.

The lifting arms 14a, 14b define a load receiving space 18 with the housing 12 connecting them. The load receiving space 18 has a substantially rectangular cross-sectional shape and is open to one side, down here. Via this opening, a load-receiving means, such as a rope, a chain or a fixedly attached to the load eyelet, are introduced into the load receiving space 18. In the load receiving space 18, a component 20 can be inserted, which has a locking part 24 for closing the open side of the load receiving space 18. The locking part 24 is formed like a bar and connected to a control part 26 via a likewise beam-like web portion 28. The locking part 24, the control part 26 and the web part 28 form the movable member 20 of the lifting device 10. In the jargon, the component 20 is sometimes referred to as a "pawl".

In the 1a and 1b the component 20, which is movable about a pivot axis S, is pivoted into the load receiving space 18 and delimits, with the lifting arm 14a shown on the right, a receiving space 22 for the load-carrying means not shown in the figures. The receiving space 22 is a partial space of the load receiving space 18 and also has a substantially rectangular cross-sectional shape. According to a translational movement T1, in the representation of Fig. 1a from top to bottom, the locking part 24 has been brought into the locked position shown and there in abutment with abutments 30a, 30b. The abutments 30a, 30b are respectively in the end region associated with the open side of the load receiving space 18 arranged the lifting arms 14a, 14b and formed as a cylindrical web (abutment 30b) or as a wedge-shaped receptacle (abutment 30a).

About a translational return movement T2, in the representation of Fig. 1b from bottom to top, the locking member 24 is in the released position and out of engagement with the abutments 30a, 30b brought. In Fig. 1b are the counter to the abutments 30a, 30b formed locking lugs 32a, 32b of the locking member 24 clearly visible. The one latching nose 32 a is at the in the Fig. 1a to 1d shown on the right, free end of the locking part 24 is formed and engages in the wedge-shaped abutment 30a on the lifting arm 14a. At the opposite end of the locking part as a kind of extension, the locking lug 32b is formed to rest against and on the cylindrical abutment 30b on the lifting arm 14b.

In the in Fig. 1b shown released position engages the locking member 24 with a locking lug 32a in a formed on web-like lifting arm 14a recess 34 (see. Fig. 1c and 1d ) one. The component 20 can be pivoted about the pivot axis S in the block-like widened lifting arm 14b such that the other latching nose 32b of the latching part 24 protrudes from the housing 12 on the side of the lifting arm 14b opposite the load receiving space 18. The pivot axis S is arranged centrally on the control part 26. In the region of the pivot axis S, a restoring device 36 for the translational return movement T2 of the latching part 24 is arranged.

Fig. 2 shows the return device 36 in detail. In the control part 26, a slot 38 is formed, in which a fastening bolt 40 is inserted along the pivot axis S and fixed to the housing 12 for pivotally mounting the control part 26. Perpendicular to the fastening bolt 40, a screw 24 is supported on this, which is acted upon by a compression spring 44. The compression spring 44 causes a movement of the control part 26 in the vertical direction of the screw 42, corresponding to the translational return movement T2 in the vertical direction. The screw 42 with the compression spring 44 as a central element of the return device 36 is arranged in an extension 46 of the web-like control part 26. If a tension spring is used instead of the compression spring 44, this exerts a force on the locking part 24 at least in its closed position, so that the latching lugs 32a, b are held with a predeterminable contact pressure on the abutments 30a and 30b. In this way, the locking part 32 is held particularly secure in its closed or locked position.

Via an operating element 48, which is arranged in the connecting region of web part 28 and control part 26, the control part 26 and with it the movable component 20 in a rotational movement R1 from the load receiving space 18 in the housing 12 is pivotable, as in Fig. 1c and 1d shown. An opposing rotational return movement R2 is effected by the further restoring device 50, which is arranged in an actuating part of the housing 12 adjoining the pivoting region of the component 20. The further restoring device 50 is a spring-elastic element fixed to the attachment point 54c. The housing 12 and the components arranged in or on it are via fastening means, of which in the Fig. 1a to 1d only two are designated 54b and 54c, firmly connected.

The lifting device 10 is characterized in that the locking part 24 from the in the Fig. 1a locked position not shown in the Fig. 1c and 1d shown, the access to the load receiving space 18 releasing position can be moved. The translational return movement T2 in the in the Fig. 1b shown dissolved position is imperative and thus constitutes a securing mechanism. About a cable 52, the control part 26 is connected to an insertion funnel 53 of an electric motor, not shown.

Accordingly, the cable 52 in the illustration of Fig. 1c and 1d shortened compared to the representation in the Fig. 1a and 1b ,

The resilient element comparable to a metal strip formed further restoring device 50 is located on the other lifting arm 14b associated part of the top of the control part 26 on this and exerts a spring force on this. About the spring force applied by the further restoring device 50, the rotational return R2 of the component 20 (see. Fig. 1d ) causes. The elastic return device 50 rests against the end of the control part 26 assigned to the web part 28, the fastening means 54c representing the axis of rotation for the restoring force acting in the radial direction. The cable 53 is guided through a slot 55 formed in the further restoring device 50 and open towards the free end. Regardless of the pivot position of the component 20 and the voltage applied to him further restoring device 50, the cable 52 engages the control part 26, wherein the force acting on the cable 52 electric motor a rotational movement R1 to open the load receiving space 18 and the further restoring device 50 a rotational movement R2 for closing of the load receiving space 18 causes. Alternatively, another cable, not shown in the figures, can be provided on the free end of the control part 26 associated with the one lifting arm 14a and connected to the insertion funnel 53. About this further cable a restoring force on the control part 26 as part of the component 20 can be applied.
