Definitions
- the invention relates to a load loading crane, in particular a container loading crane, comprising a crane bridge extending in a transfer direction, a first lifting unit, a second lifting unit which is arranged at a distance in the transfer direction from the first lifting unit, the first lifting unit and the second lifting unit each have at least one lifting mechanism with assigned load-carrying means, and a transfer unit arranged between the lifting units, the transfer unit and the lifting units being designed such that loads can be exchanged between each of the lifting units and the transfer unit.
- Such a loading crane is known, for example, from DE-PS 19 06 212.
- the well-known crane is used for loading and unloading container ships.
- the first lifting unit the so-called water or ship trolley
- the transfer trolley transfers this container on land to the second lifting unit, the so-called land trolley, which then places the container on land, while the transfer trolley returns to the first lifting trolley.
- the working time for loading and unloading load carriers has so far been limited by the two lifting trolleys.
- the time required for loading the container ship from the ship's cat, for example, to lower a container, to uncouple the load handler from this container, to transfer the load handler to another container, to couple the load handler to this further container and for Raising the further container to the transfer cat was usually longer than the travel time required by the transfer cat from the ship cat to the land cat and back to the ship cat including the respective handover times.
- a conveyor unit is provided on the side of the second lifting device facing away from the transfer direction of the first lifting unit, the conveyor unit and the second lifting unit being designed such that loads can be exchanged between them, and wherein the conveyor unit has at least one delivery / acceptance points for loads.
- the transfer path covered by the transfer trolley is shortened with a corresponding reduction in the transfer times between the ship and land trolley, as a result of which the working time of the cargo loading crane is also shortened.
- the conveyor unit have at least two conveyor lines, each with a delivery / acceptance point for loads.
- the at least two conveyor lines are arranged one above the other.
- a conveyor line can have, for example, a conveyor platform which can be moved on rails extending in the transfer direction.
- the conveyor platform can be formed by a fixed plate which can be moved on the rails by means of rollers attached to it.
- the conveying section can also take on the function of a buffer to compensate for the conveying rates of the load loading crane and a transport device downstream of the delivery / acceptance point for loads.
- a transfer device can advantageously be provided at both ends of the conveyor line and return line in order to enable transfer of at least one conveyor platform from the conveyor line to the return line or vice versa.
- the base plane i. the base supporting the load loading crane is essentially kept free and, for example in the event of a malfunction or failure of the transport device downstream of the delivery / acceptance point for loads, is used to maintain emergency operation.
- an essentially free base level enables special operation to be carried out, for example the reloading of loads to be delivered in a hurry, directly from the loading loading crane to trucks or the like.
- the load loading crane can have an additional lifting unit.
- the additional lifting unit is advantageously displaceable in the transfer direction.
- the second lifting unit can be designed to be displaceable in the transfer direction. If necessary, this enables offset runs to be carried out by the width of one or more loads, for example when exchanging loads with the transfer unit, which will be discussed in more detail below.
- a particularly simple construction results here if the second lifting unit can be displaced in the transfer direction on a transport track provided on the crane bridge.
- the second lifting unit can also be designed to be non-displaceable in the transfer direction, which enables cost savings since the second lifting unit does not require a horizontal drive.
- the first lifting unit can be moved past the second lifting unit if necessary. The latter is advantageous, for example, in the case of container loading cranes used in freight ports for depositing the loading hatch covers present in older-type container ships.
- Instruction areas for the load receiving means of the second lifting unit are arranged on the load loading crane.
- guide means for the load-carrying means of the second lifting unit can be provided on the load-loading crane in order to be able to essentially exclude such pendulum movements from the outset.
- the loads at the delivery / acceptance points be supported by an essentially continuously promoting transport device. direction taken over or delivered to an essentially continuously conveying transport device.
- the transfer unit has a load receiving area with a load receiving area and that an operating device is assigned to the load receiving area by means of which the load receiving area is used to exchange loads with a front one
- Lifting units is adjustable in a forward direction between a transfer position and a front operating position and is adjustable in a rearward direction between the transfer division and a rear operating position for load exchange with a rear one of the lifting units.
- the operating device extends and transfers a load to the lifting mechanism or accepts a load from it.
- the operating device then moves back into the transfer unit. Then or at the same time, the transfer unit begins the transfer journey to the other lifting unit.
- the entire mass of the transfer unit does not have to be accelerated in the load loading crane according to the invention for transferring or taking over a load. Accelerating the much smaller mass of the operating device requires less time, which results in shorter working cycles, and moreover also saves energy which conventionally had to be used to accelerate the large masses.
- equipping the transfer unit with an operating device also has advantages in terms of control technology, since the control of the movements of the transfer unit and of the lifting mechanisms of the lifting units is unbundled, that is to say carried out independently of one another can be.
- the transfer unit In the case of a conventional freight loading crane, the transfer unit must brake in front of the respective lifting unit, wait for the lifting device to be fully lifted, and finally move on to exactly below the lifting unit, ie the movement of the transfer unit must be coordinated with the movement of the lifting unit of the lifting unit.
- the transfer unit moves directly to its end position next to the lifting unit. If the hoist has reached its end position, ie its highest position, the operating device is extended in response to a corresponding signal.
- a further shortening of the working cycle times can be achieved in that the transfer unit has at least two load receiving areas, each with a load receiving area, the load receiving areas being arranged and / or designed such that each of them is used to transfer loads from the lifting units to the load receiving area and can cooperate with each of the lifting units to take over loads by the lifting units from the load-receiving surface (hereinafter briefly: load exchange with the lifting units).
- each of the lifting units when they meet the transfer unit can first transfer the load carried by them to a first of the receiving areas and then independently of this remove the load supplied by the transfer unit from the second receiving area.
- the lifting unit al ⁇ the Transferein ⁇ ness loaded to the meeting point, exchange their loads out there and leave the meeting also reloaded.
- At least one of the load-receiving areas has an operating device by means of which the load-receiving surface for load exchange with a front of the lifting units in a forward direction is adjustable between a transfer position and a front operating position and for load exchange with a rear one of the lifting units is adjustable in a reverse direction between the transfer position and a rear operating position.
- the operating device it is proposed for all container loading cranes according to the invention that it has at least one extendable element with a base part fastened to the transfer unit and at least one telescopic part which is telescopically adjustable in the forward and backward directions relative to the base part.
- the load-bearing surface can be formed here by a surface of the telescopic part facing away from the base part.
- the operating device can have a platform which can be extended on rails projecting in the forward direction and backward direction from the receiving area.
- This embodiment is characterized by particularly high stability due to the fixed rails.
- the platform can be formed by a fixed plate which can be extended on the rails by means of rollers attached thereto, the load-bearing surface being formed by an upper, horizontally running surface of the fixed plate. Using such a platform results in a stable and yet space-saving construction of the operating device.
- the platform is formed by an endless belt that is drawn around a guide body that can be extended on the rails by means of roller elements, the load-bearing surface being formed by an upper, horizontally running part of the endless belt.
- the two load-bearing areas are arranged one above the other, at least the lower load-bearing area rich, preferably both load-bearing areas, has an operating device.
- the two load receiving surfaces are fixed relative to the assigned load receiving areas and can be pivoted together relative to the transfer unit about an essentially horizontal axis, while maintaining their orientation relative to the transfer unit .
- the two load-bearing surfaces can be fixedly arranged on a substantially horizontal turntable that can be rotated about an essentially vertical axis.
- the transfer unit of which has at least two load receiving areas in the case of a load loading crane which can also be operated in double play, the transfer unit can have a load receiving area, with each of the lifting units being assigned at least two hoists, each with associated load carrying means, each of which is associated with The load receiving area for transferring loads to the load receiving surface and for taking over loads from the load receiving surface can cooperate regardless of whether the respective other hoist assigned to the same lifting unit has taken up a load or not.
- each of the lifting units at a meeting with the transfer unit can first take over the load it has delivered from the load-receiving area with the currently empty load-carrying means and then transfer the load carried by the other load-carrying means into the receiving area.
- load carriers such as container ships, can be loaded and unloaded simultaneously in double play operation.
- the transfer unit can be designed to be displaceable in the transfer direction. This has the advantage that the distances to be covered can be divided between all three units, lifting units and transfer unit, with corresponding time savings. A particularly simple construction results here if the transfer unit can be displaced in the direction of transfer on a transport path running between the longitudinal ends of the crane bridge.
- the transfer unit it is also possible for the transfer unit to be designed to be non-displaceable in the direction of transfer.
- the transfer function is also taken over by the two lifting units. This can be done in a simple manner in that the transfer unit is fixedly arranged on the crane bridge, for example on its lower cross members.
- the transfer unit is arranged so as to be movable on a base supporting the load loading crane in a direction that is essentially orthogonal to the transfer direction. In both cases, the transfer unit can follow the load loading crane during its movement along the quay, ie crthogonal to the direction of the cat ride. But even a firm arrangement on the surface carrying the load loading crane is conceivable.
- the invention relates to a method for transporting loads between two horizontally spaced load-storage areas, in which the loads are raised in both load-storage areas and in each case at least by a load-receiving and transport system associated with a first of the load-storage areas along a first section and by at least one load pick-up and transport system belonging to a second of the load-parking areas are transported along a second section, with a transfer from the first load-pick-up and transport system to the second load-pick-up and transport system using a twin between the two sections ⁇ shear carrier system takes place, and an additional conveyor system is used to transport the loads along at least one of the first and second sections in addition to the respective load pick-up and transport system.
- the use of the additional conveying system shortens the path to be taken to replace the two load pick-up and transport systems and thus also reduces the working time which determines the transport rate of the method.
- loading and transport systems for example. the above-described lifting units, the intermediate carrier system, the above-described transfer unit and, as an additional conveyor system, the above-described conveyor unit can be used.

Meanwhile, the transfer trolley 932 is on a water journey without a container (arrow W). It is understood that the conveyor line 964s can be used both for loading and for unloading.
- the large size of transfer cat In order to move the transfer cat under the land cat, the large size of transfer cat must include the size of the Unloading containers are accelerated and braked again and also to release the space under the land cat, the mass of the transfer cat must first be accelerated. On the one hand, much time is required to accelerate this large mass and, on the other hand, a lot of energy has to be used.
- the transfer trolley 932 If the transfer trolley 932 has reached the water trolley 928 according to FIG. 15d, it is locked with it. If the spreader 928c of the water trolley 928 is in its highest position together with the unloading container 922E ", the operating device 936s extends on the water side. The spreader 928c then places the unloading container 922E" on the container mounting surface 938s and is decoupled from it ⁇ pelt.
- the land cat 926 has meanwhile placed the unloading container 922E 'on the conveyor line 964s and is beginning to lift its spreader 926c in the direction of arrow II 1 .
- the container loading crane according to the invention also saves both time and energy compared to the conventional container loading crane when it comes to the container handover on the water side.
- equipping the transfer trolley with an operating device also has advantages in terms of control technology, since the control of the movements of the transfer trolley and the lifting mechanisms of land or water trusses is unbundled, ie can be carried out independently of one another.
- the transfer trolley has to brake in front of the respective lifting trolley, wait for the spreader to fully lift and then move on to exactly below the lifting trolley, ie the movement of the transfer trolley has to be coordinated with the movement of the lifting trolley of the lifting trolley .
- the transfer trolley moves directly to its end position next to the lifting trolley. If the hoist has reached its end position, ie its highest position, the operating device is extended in response to a corresponding signal.
- the operating device is preferably designed in such a way that in its maximally extended state it has the required relative positioning to the lifting mechanism of the lifting trolley.
- the use of the loading loading crane according to the invention is not restricted to loading and unloading of container ships. Rather, it can be used with advantage wherever large quantities of general cargo are to be implemented in the shortest possible time. It should also be noted that the number of conveyor lines and the transport rail levels can be chosen as required.
