Definitions

  • the invention relates to a lifting device, in particular a lifting clamp, which can be used, for example, to lift wooden panel walls.
  • the invention also relates to a load-carrying arrangement comprising at least two such load-carrying means.
  • Load handling devices of the type mentioned are already known in a wide variety of embodiments and are used for lifting a wide variety of loads.
  • the object of the invention is to provide a load-carrying device of the type mentioned at the outset, which is particularly suitable for handling wooden panel components without damaging them visibly from the outside by attaching the load-carrying device.
  • a load handling device with the features of independent claim 1 is first proposed.
  • a load-carrying device in particular a lifting clamp, is proposed, in particular, with a base element, a pull strap movably mounted on the base element and at least one expanding leg pivotable between an initial position and a spread position and mounted on the base element, the pull strap being connected via a coupling element, for example via a coupling rod, is connected to the at least one spreader leg in such a way that the at least one spreader leg can be moved by moving the pull tab relative to the base element between the initial position and the spread position.
  • a preferably linear movement of the pull tab caused by a pull on the pull tab can in this way be converted into a movement of the expansion leg are implemented in its spread position or at least in the direction of its spread position.
  • the at least one expansion leg can preferably be mounted pivotably on the base element and thus pivoted between its initial position and its expanded position on the base element.
  • the at least one expansion leg In the starting position, the at least one expansion leg can be folded in and/or approached to the base element with its free end and/or arranged within a receiving space defined by the base element.
  • the at least one expansion leg In the initial position, the at least one expansion leg can be stowed away in the base element.
  • the at least one spreader leg In the spread position, the at least one spreader leg can be folded out and/or its free end can be further away from the base element than in the starting position.
  • the coupling element is preferably designed as a coupling rod. This enables a transfer of tension and pressure between the pull tab and the at least one expansion leg.
  • a coupling element can be assigned to each expansion leg of the load handling device.
  • the coupling element is connected to the pull tab via a joint and to the spreader leg via a joint.
  • the at least one expansion leg can be moved into the expanded position by a pulling movement of the pull tab in the direction of its free end.
  • the load-carrying means has two spreader arms, which are each mounted on the base element so that they can be moved, preferably pivoted, between an initial position and a spread position.
  • the pull tab can be connected to each of the two spreader legs via a respective coupling element.
  • a load-carrying means is provided that can hook particularly reliably in a receiving opening of a load and that is therefore particularly suitable for lifting even comparatively heavy loads, such as wooden panel components.
  • Each coupling element is preferably connected to the pull tab via a joint and to its respective expansion leg via a joint.
  • the two spreader legs of the load-carrying means are arranged on two different sides of the pull strap of the load-carrying means.
  • the load handling device is given a symmetrical structure, at least in relation to the two expansion legs uniform application of force when lifting a load in the load handling device.
  • the pull tab can be mounted so that it can move linearly on the base element and/or between the expansion legs. A movement of the pull tab, in particular a linear movement of the pull tab, can thus take place between the two expansion legs.
  • the linear movement of the pull tab can be converted into a movement, in particular into a pivoting movement of the two spreader legs, via the coupling elements.
  • the coupling elements can be aligned at an acute angle to a longitudinal center axis and/or to a direction of movement of the pull tab. In this way, it is ensured that a tensile force that is transferred to the pull tab when a load connected to the load handling device is lifted is reliably converted into a clamping force with which the load handling device can be releasably fixed to the load.
  • the above-mentioned acute angle between the coupling elements and the longitudinal center axis and/or to the direction of movement of the pull strap is also advantageous in order to be able to detach the load handling device from the load.
  • the pull tab can have a suspension point, for example an eyelet, for suspending a hoist.
  • the load handling device can be attached to a hoist via the pull strap and the pull strap when lifting from a starting position in which the at least one spreader leg is applied or folded in, move to an extended position.
  • the preferably linear movement of the pull tab in the pull direction is converted into the movement, preferably into the pivoting movement of the at least one spreader leg from its initial position into a spread position spread apart from the base element.
  • the load-carrying device can be automatically fixed to the load to be lifted when a tensile force is transferred to the load to be lifted via the pull strap of the load-carrying device.
  • the free end of the pull tab can be the end of the pull tab that faces away from the base element of the load handling device.
  • this has a locking device.
  • the locking device can be set up to lock the at least one expansion leg in its applied initial position and/or in an intermediate position between the initial position and the expanded position.
  • Locking the at least one expansion leg in its initial position can be helpful in order to lift the load handling device by pulling on the pull strap and thereby separating it from the load to be lifted, without the at least one expansion leg being moved from its initial position into its spread position by the pull on the pull strap is moved in which it would prevent the load handling attachment from separating from the load to be lifted, as intended.
  • the locking of the expansion leg thus serves to hold the expansion leg in its initial position independently of a load on the pull tab.
  • Locking the at least one spreader leg in an intermediate position between the initial position and the spread position can be helpful if the Load handling equipment is to be used in an opening of a load which is formed in an inclined surface of the load and/or which has a longitudinal central axis which is oriented obliquely to the direction of gravity.
  • Such a situation can arise, for example, in the case of so-called gable walls, that is to say wooden panel construction walls which have a gable.
  • openings for inserting the load-carrying means are often arranged on an inclined surface and then have longitudinal center axes oriented obliquely to the direction of gravity.
  • the at least one expansion leg can be moved from its initial position into an already slightly expanded expanded position by pulling on the pull tab.
  • the locking of the at least one expansion leg in the intermediate position outlined above can be used to keep the load handling device fixed to a load in an obliquely oriented insertion opening and to prevent the load handling device from being pulled out of the insertion opening before the at least one expanding leg is properly expanded has.
  • the at least one expansion leg is locked in the intermediate position with play, ie with room to move.
  • the locking of the expansion leg in the position can therefore be designed in such a way that the expansion leg can still cover a remaining adjustment path from its locked intermediate position to its proper spread position by pulling on the pull tab.
  • the Locking of the at least one expansion leg in its intermediate position can thus be understood as a lower stop, which effectively prevents the expansion leg from returning from the intermediate position to its starting position, for example due to the force of gravity.
  • An upper stop which defines the spread position of the at least one spreader leg, can be provided between the base element and the pull tab and/or between the base element and the at least one spreader leg.
  • the pull strap has a guide recess, for example a longitudinal slot, the upper edge of which can define the starting position and the lower edge of which can define the maximum spread position of the at least one spreader leg.
  • the base element can have a guide element that fits the guide recess, which serves to limit the travel of the pull tab and is arranged on the base element in the guide recess of the pull tab when the pull tab is in the position of use.
  • the length of the guide recess which is preferably designed as a longitudinal slot, and the guide element on the base element can then define a maximum linear adjustment path for the pull tab on the base element.
  • the locking device has at least one actuating lever for activating and/or releasing the locking.
  • the locking device can have an actuating lever for locking in the initial position and for locking in the intermediate position. In this way it is possible to activate or release the locking for the intermediate position and also the locking for the starting position separately from one another. It can be advantageous if the actuating lever or levers is/are set up to to be connected to a pulling element, for example a rope, a cord or a cable. In this way it is possible to actuate the actuating lever or levers of the lock in a simple manner, even from a distance.
  • a pulling element for example a rope, a cord or a cable.
  • an electrical, in particular an electromechanical, actuating device is provided for actuating the locking device for activating and/or releasing the locking.
  • the locking device for locking the at least one expansion leg in the starting position can have a locking bolt and a bolt receptacle.
  • the bolt receptacle can be formed on the pull tab and the locking bolt can engage in the bolt receptacle in the locking position in order to fix the pull tab in its initial position on the base element. If the bolt receptacle for locking the at least one expansion leg in the starting position has no or only a minimal oversize compared to the locking bolt, the locking bolt and thus ultimately also the expansion leg can be fixed in the starting position without play or largely without play.
  • the locking device for locking the at least one expansion leg in the intermediate position has a locking bolt and a bolt receptacle.
  • the bolt receptacle can be formed on the pull tab and the locking bolt can engage in the bolt receptacle in the locking position in order to fix the pull tab in an intermediate position on the base element.
  • the bolt receptacle for the intermediate position can preferably be an elongated hole aligned in the direction of movement of the pull tab to the base element and/or have an oversize in the direction of movement of the pull tab to the base element compared to a cross section of the locking pin relevant for locking. In this way it is possible to lock the to provide at least one expansion leg in the intermediate position with the aforementioned play.
  • the pull tab can be moved further in the pulling direction within the limits specified by the bolt receptacle, so that by pulling on the pull tab, the at least one expansion leg can be removed from the Intermediate position can still be moved into the spread position.
  • At least one locking bolt preferably both of the aforementioned locking bolts, can be movably mounted on the base element between a locking position and a release position. It can be advantageous if at least one locking bolt, preferably both locking bolts, is/are movably mounted against a restoring force of one, preferably one in each case, restoring element from its arresting position into a release position or vice versa. The restoring force of the restoring element ensures that the locking bolt remains in its respective locking position or in its release position when the locking device is not actuated.
  • the locking bolt for locking the at least one expansion leg in the starting position i.e. in the position in which the at least one expansion leg is folded in and the load suspension device is not fixed in a corresponding insertion opening of a load, against the action of a Restoring element from the locked position is movable into a release position. This ensures that the locking bolt remains in its locking position when the locking device is not actuated.
  • the locking bolt for locking the at least one expansion leg is movable in its intermediate position against a restoring force of a restoring element from its release position into its locking position.
  • the restoring element can be prestressed.
  • the locking can thus be released automatically and easily by actuating or possibly remotely actuating the actuating lever assigned to the locking bolt for locking the at least one expansion leg in its intermediate position. If the actuating lever is moved into a release position, the restoring element relaxes and the locking bolt can be moved by the restoring element from its locking position into its release position and the at least one expanding leg can be moved back into its folded-in initial position without restrictions by the locking bolt.
  • the locking of the at least one expansion leg in its initial position can be activated. This is possible by actuating or possibly remotely actuating the actuating lever of the locking device, which is assigned to the locking bolt for locking the at least one expansion leg in its initial position. Due to the restoring force of the restoring spring, the locking bolt then automatically moves into its locking position when the actuating lever is actuated.
  • a locking bolt namely preferably the locking bolt for the intermediate position of the at least one expansion leg, can be locked in its locking position, preferably with an actuating lever of the locking device, for example the one already mentioned above.
  • At least one locking bolt in particular the locking bolt for the starting position, can be locked in a locking position. This preferably with one, for example with the previously mentioned actuating lever of the locking device.
  • the at least one expansion leg can have a friction-increasing coating and/or a friction-increasing structure, for example teeth, on its contact surface facing a load in the position of use. In this way, it may be possible to transfer higher forces with the load handling device and, if necessary, to lift even higher loads.
  • the load handling device has a fastening interface for fastening a spacer bar, in particular on its base element.
  • Two or more load handling devices can be coupled to one another via a spacer rod in such a way that they maintain their position relative to one another. In this way it is possible to provide and lift a load with two or more of the aforementioned load handling devices. Not only the insertion of the load-carrying devices into corresponding insertion openings on the load to be lifted, but also the removal of the load-carrying devices from the insertion openings is considerably simplified by fixing the relative distance between the load-carrying devices by the spacer bar.
  • a load-carrying arrangement comprising at least two load-carrying means is also proposed, the load-carrying means being connected to one another via a spacer bar.
