Definitions
- the invention relates to a device that can be moved on a carrier for lifting and transporting large containers of different external dimensions, with a Einteilvor ⁇ device for adapting the distance of the fasteners to the spacing of the load-bearing points on the large containers and a hoist.
- the large containers include containers, swap bodies and semitrailers, i.e. freight containers, which are intended in particular for goods that are not or only lightly packaged, moisture-sensitive or for the formation of larger loading units.
- Such large containers not only save packaging, but also increase the speed of handling.
- the large containers mentioned each have different sizes, which is why the lifting and transfer devices for such large containers with their receiving and transport devices must be designed flexibly.
- gripping devices for container handling are known, which are referred to as spreaders and can be equipped with additional interchangeable platform tongs to accommodate swap bodies and semi-trailers.
- the spreaders have so-called twistlocks with which the containers can be gripped from above.
- gripping claws are provided, which can engage in the gripping pockets attached to the below-mentioned containers.
- the twistlocks are set to the different container lengths in the spreader by means of telescopic devices which, when extended, are subjected to a great deal of bending.
- the uniform device namely the guide columns with lifting elements, means that different gripping elements, such as were previously available in the form of twist locks on the one hand and pivoting gripping arms on the other hand, can be dispensed with. Weight is also saved by eliminating the previously required spreader.
- the lifting vehicle can be equipped with any number of wheels, so that the wheel load can be chosen to be correspondingly low.
- the distance between the respective opposite guide columns can preferably also be changed, for example via a displacement device which is provided in a cross member on the lifting vehicle.
- the variability in distance creates, on the one hand, the possibility of dispensing with additional pivoting or sliding devices for the fastening means, since the fastening means can be moved together with the guide columns relative to the large container.
- the fastening elements with the load-carrying points of the containers or the gripping pockets of the swap bodies or semitrailers are brought into engagement or into the engagement position and released again by moving them apart.
- the lifting vehicle is preferably suspended from the lower flange of a carrier so that it can be moved, for example, in a high-bay warehouse.
- the carriers preferably consist of I or U profiles, so that, for example, large containers of corresponding width can be placed on the upper flanges of the carrier of the lower level of a shelf storage below.
- a carrier can thus serve both with its upper flange as a depositing level and with its lower flange as a track for a lifting vehicle of the level below.
- a preferred embodiment of the fastening element is that it can be brought into engagement with both the lower load-bearing points of the containers and with the gripping pockets of the swap bodies and semitrailers.
- the fastening element is equipped with a claw for the gripping pockets, in which, at right angles to it, a bolt which is displaceable in the direction of its longitudinal axis and is secured against rotation is arranged and which is held by a spring in the normal position, i.e. its extended position is held.
- the fastening elements are brought into engagement position by reducing the distance between the respective opposite guide columns.
- the bolts engage in the elongated holes in the load suspension points. Slipping of the container is prevented by two lugs located at the front end of the bolt, which engage behind the elongated holes when the container is lifted.
- the lifting vehicle consists of two semi-vehicles, each arranged on or on a carrier, which, viewed in the transport direction, can be moved relative to one another.
- the semi-vehicles can thus be moved together or independently of one another into the position which enables the fastening elements on the large container to engage on both sides.
- the lifting vehicle or the semi-vehicles are supported by several wheels.
- the separate controllability of the lifting drives enables even inclined loading units to be picked up.
- the lifting drives are controlled synchronously to lift the containers.
- their drives can also be controlled separately so that they can be positioned according to the container size or the position of the load suspension points. They are controlled synchronously for horizontal transport.
- FIG. 1 shows a side view of an embodiment of the invention in a high-bay warehouse
- FIG. 1 is an end view of the embodiment of FIG. 1,
- Fig. 3a shows a fastener in section
- FIG. 3b shows a fastening element in a side view (from the view Illb-IIIb according to FIG. 3a),
- Fig. 4 is a fastener with recorded Con tainer and
- Fig. 5 is a fastener with an interchangeable container or semitrailer.
- the illustrated embodiment shows, as part of a high-bay warehouse, respective vertical supports 10, on which respective supports 11 and 12 are arranged at a distance from one another as double-T supports.
- Lifting vehicles 13, which are equipped with running wheels 14, can be moved on the lower flange track of the upper carrier 11.
- the lifting vehicle consists of two semi-vehicles of identical construction, each of which, as can be seen from FIG. 1, has two vertical guide columns 15, each of which vertically guides lifting elements 16 which are equipped with gripping elements 17 at the lower end. Both the distance between two guide columns 15 lying one behind the other in the direction of travel (see FIG. 1) as well as the distance between two opposite guide columns 15 (see FIG. 2) can be adjusted, the latter via a cross member 18 or a corresponding telescopic unit.
- the lifting elements on each side of a large container 19 to be accommodated can be driven separately if required.
- the fastening element 17 is fastened to the lifting elements 16 and has a U-shaped claw 23 for gripping pockets of swap bodies or semi-trailers.
- the fastening element 17 also has a bolt 20 which can be displaced in the direction of its longitudinal axis and is secured against rotation, which can be inserted by a spring 21 in the unloaded state in the extended position (normal position) and which can be inserted into the elongated holes of the load-receiving points of containers.
- the relative position of the fastening element 17 with respect to a received container is FIG. 4 and to a received one Semitrailer can be seen in Figure 5.
- the bolts 20 are inserted into elongated holes 22 of the load-bearing points of the container.
- the bolt can preferably also have one or two lugs 25 which prevent slipping by engaging behind the elongated holes when lifting.
- the claw 23, as shown in FIG. 5, is used. First, the bolt 20 comes into contact with the swap body or semi-trailer, being pushed back against the force of the spring 21. The claw 23 engages in a corresponding undercut in the gripping pockets 24 of the swap body or semitrailer.
- the device according to the invention works as follows:
- the guide columns 15 are positioned by moving the semi-vehicles in such a way that the fastening elements 17 lie exactly opposite the load-carrying points, namely the elongated holes 22 or gripping pockets 24. If the large container 19 is not in a horizontal position, the individual fastening elements 17 can be brought into the desired height by the separate actuation of the lifting elements to the load receiving points. Subsequently, the opposite guide columns 15 are moved towards each other with the aid of the telescopic unit in the traverses 18 until either the bolts 20 protrude into the elongated holes of the container or the claws 23 come to rest on the gripping pockets after the bolts 20 have been pushed back.
- the lifting elements 16 are actuated synchronously with the lifting of the large container 19, the nose 25 engaging behind the elongated holes 22 when lifting a container or the claw 23 engaging behind the undercut of the gripping pocket 24 when lifting an interchangeable container or semi-trailer.
- REPLACEMENT BLA ⁇ (RULE 26) If the device described is part of a high-bay warehouse, the container 19 is only raised enough to have sufficient freedom with respect to the upper flange of the carrier 12 (or the storage base) during horizontal transport.
- the lifting vehicle consisting of two half-vehicles, is moved into the desired position with synchronized switching of all wheel drives with a suspended container 19, after which the lifting devices 15 are lowered again until the container 19 is parked.
- the drives of the semi-vehicles 13 are controlled separately, they can easily be positioned according to the size of the containers 19 to be moved and the spacing of the pockets or load bearing points (elongated holes 22). This device makes the otherwise usual telescopic device unnecessary, which saves considerable weights and the overall height can be minimized.
