Definitions
- the present invention relates to a load lifting system mentioned in the preamble of claim 1.
- the term “Prisms” include bodies of the same type as, for example Cuboids, cubes or truncated pyramids.
- the term “cable pull” includes simple load ropes as well as pulley blocks with one lower, loose roller arrangement.
- Load lifting systems of the generic type are particularly used for lifting and handling large containers.
- the crane scaffold is generally a rail-bound one or free-moving container truck with one Trolley carrying the load lifting system.
- the movement of the container pallet truck enables large-scale transport of the container between individual stacking places.
- the Rough positioning of the container at the stacking place in the two horizontal axis directions in turn takes place through the Movement of the container truck and if necessary by the movement of a trolley; the general
- the lifting and lowering movement is carried out by actuating the Rope drums; generally several or also all cables of a load lifting system on a common one Rope drum led.
- the described possibilities of movement generally do not allow the burden of the modern Container handling operations require accuracy position and align.
- the permissible position deviation for example, two large containers stacked on top of each other is at most 10 mm. Hence the need To create facilities to the lifting system in the horizontal plane to move and rotate small amounts.
- FIG. 1 This shows schematically one approximately rectangular container C with a major transverse axis X, a main longitudinal axis Y and a vertical axis Z. displacements in the direction of the X or Y axis are called X or Y movements, Rotations around the X axis, the Y axis and the Z axis, respectively referred to as pitching movements, rolling movements or yawing movements. These terms are also used in the following.
- a load lifting system to create the generic type, which with compared to the prior art simpler means at least the X and Y movements as well as the yaw movements allowed.
- a load lifting system in the preamble of the claim 1 type is defined by each of two load levels Corner area of the fictitious prism each assigned a pair of cables, which each pull a cable from one of the two includes the load planes forming the corner.
- the invention provides that additional adjusting means are provided to the cables at least individual pairs of cables to adjust in the same direction and in a coordinated manner. These additional Adjustment means allow individual corners or Raise or lower edges of the fictitious prism and up this way the load lifting system to one or both of the each other to tilt vertical horizontal axes.
- At a particularly simple arrangement are at least two in the direction of a main longitudinal axis and / or two in the direction cable pairs adjacent to a main transverse axis of the prism equipped with the additional adjustment means.
- the simultaneous and same-directional adjustment of two neighboring ones Cable pairs immediately result in a tilting movement around one of these two axes.
- the term "coordinates to adjust" means that generally in the case of one Tilting involved possible differences must be taken into account for their distance from the tilt axis.
- Rope force compensation devices are provided between at least individual cables of the load lifting system.
- Rope force compensation devices can achieve that all cables connected to such a device bear the same loads. This allows, for example uneven changes in length of the ropes, uneven Compensate rope pulley diameter etc.
- rope balancing devices are in particular between two Cables of a pair of cables provided.
- the adjustment mechanisms can for an opposite adjustment of the cables a load level are released. This measure allows, for example, if as a result high driving accelerations external horizontal forces the load act and shift that from that shift adjustment mechanisms of the displacement movement concerned in each case can follow this way To prevent individual rope sections from becoming slack.
- an adjustment drive adjustable in two directions attacks comes as the adjustment drive Actuating cylinder, an electric threaded spindle drive or the like. If that through Connect the two free ends of rope formed in one Is adjusted, a rope end in the sense of a Shortening the assigned cable pull, the other end of the cable adjusted in the sense of an extension of the assigned cable pull, so that the desired opposite adjustment of the two cables with a single actuator is effected.
- the free ends of the two cables on each load level are articulated on a connecting link arrangement, and that on the link assembly in one direction adjustable actuator attacks.

- the pressures in the hydraulic cylinders of a cable balancing device equalize over the equalization lines off until the same in all hydraulic cylinders Pressure and therefore the same traction in all ropes prevails.
- the adjustment mechanisms for the opposite adjustment the cable pulls are assigned shock absorber means to a load level which are especially when the adjustment drive is released which, for example, induced by accelerations Movement of the adjustment mechanism dampens.
- the cables are preferably simple pulley blocks with a loose pulley, the end of the drum in essentially vertical and the free end in a pointed Angle to the vertical runs upwards.
- Fig. 1 shows schematically the example of a container C the possible micro-movements necessary for precise positioning and positional alignment of a load are required. These movements include shifts in the X direction and Y direction as well as rotations around the X-axis, the Y-axis and the Z-axis.

- the pulley blocks are as simple pulley blocks, each with a lower one loose roll R formed from the end of the drum T of a pull rope S vertically upwards and if necessary after deflections on a rope drum, not shown is guided, while the other, free end E obliquely above to an attachment point P of the not shown Crane structure is guided.
- the angles ⁇ between the end of the drum and the free end are preferred for all Pulleys the same.
- Such a pendulum-free lifting system is basically known and is also called Inscribed "rope tower".
- FIG. 3 to 5 show schematically in three different Views of a load lifting system with essentially one Fig. 2 corresponding rope guide. It will therefore be here the same designations as used in Fig. 2.
- the Elements of the eight pulleys are each identified by a reference number and denotes an index number from 1 to 8.
- the rope guide is shown using individual examples Pulley blocks described in more detail.
- the free ends E1 or E2 of the pulleys F1 and F2 visible in FIG Load level 1 become the assigned attachment points P1 or P2 led.

- the additional deflection rollers Q4 and Q5 are corresponding the arrow 10 adjustable so that the associated Pulleys F4 and F5 either shortened or lengthened can be.
- the drum ends T6 and T7 of the block and tackle F6 and F7 in the corner defined by the load planes L3 / L4 are also via upper deflection rollers 06 or 07 and additional deflection rollers Q6 or Q7 led to the cable drum 8 (see Fig. 5).
- the upper pulleys O4 and O5 or O6 and O7 can each be designed as coaxial double rollers, as Fig. 5 shows.
- the additional pulleys Q6 and Q7 are also adjustable in the direction of arrow 10.
- the drum ends T8 and T1 to T3 in the through the load levels L4 / L1 or L1 / L2 defined corners are also over upper pulleys O8 and O1 to O3 and from there directly to Rope drum 8 out (see also Fig. 5).
- To the container C could also tilt around the Y axis, for example the drum ends T2 and T3 of the block and tackle pair F2, F3 also be guided over additional, adjustable pulleys, around this pulley pair together with the pulley pair F4, F5 can be adjusted in the same direction. In the illustrated embodiment however, a different one is used for tilting about the Y axis, followed the path described below.
