Description

The invention relates to a crane hitch for loading bar material into tree shelves with the possibility to store and remove materials from any floor.

Tree shelves have the advantage over shelf racks in that each bundle of material is stored on a separate floor accessible laterally. In these tree racks, however, the bar material cannot be inserted in a conventional rope way, since it has to be inserted from the aisle space between the arms of the individual floors. This requires free space above the center of gravity of the load to be stored. This can be achieved by placing the load on the forks of either the pulling crane, stacker or forklift. These devices are relatively expensive, require a special crane, or in the case of forklifts very wide aisles.

Special crane forks with automatic counterbalance balancing are used to a small extent, but they work only one-sided.

These drawbacks are eliminated by a crane hitch for loading bar material into tree shelves, consisting of a support beam with at least two sidewalls, characterized in that the sidewalls are provided on both sides with arms with abutment surfaces for abutment, these bearing surfaces lie in the non-deflected position outside the vertical plane of the hinge. The angle d that forms the contact surface with the perpendicular to the sidewall axis is greater than the angle θ that the side walls and the sidewall are perpendicular to the unilaterally loaded loading hinge.

- 2 The sling has a simple construction, can be hung on conventional types of overhead cranes, does not require wide aisles between shelves: it can load material on both sides and in case of using a crane with a double-drum trolley the material can be loaded

The principle of operation of this loading hinge is illustrated in Figures 1 to 4, wherein, Fig. 1 is a perspective view and the loading hinge of a double anchor, Figure 2 shows the deflection of the loading hinge under unilateral load, pbr. 3 shows the load on both sides of the loading hitch, and FIG. 4 shows schematically various variants of the loading and unloading of the load into atrometric racks by means of the loading hanger.

The support hinge 1 according to Fig. 1 ee consists of a support beam 2 with catches 3k fastening to the crane girder, of the side walls 4 ▼ of the lower part extended to form an anchor with arms 3 ^{3 by the} feeding surfaces 6, to load the load 2 ·

With the load 2 unilaterally loaded also according to FIG. 2, the load hinge 1 is deflected by an angle such that the resulting center of gravity of the load 2 and the load hinge 1 coincides with the load lowered from the catches 3. of the load 2 ^{2 of} any floor of the tree rack 2, on the deflection side.

When the load 2 and the other side plate arm 2 are loaded with the same weight of the load 2, the loading hinge is aligned as shown in FIG. 3. At this load one or the other load 2 can be slid into the free space of the tree shelf £ n®. , fold the load 2 on the arm 2 of the tree rack. 2 · A load 2 ^{2 of} another floor of the same or another tree rack 2 on the respective side can then be picked up on the released arm 2.

In practice, there are four possibilities of combining the loading hinge 1 according to FIG. 4. According to FIG. 4a, where the loading hinge χ is without load ²⁸ in this method, the load 2 can be removed from either side of the tree rack 2. unilaterally burdened message and load 2 lae from your side. According to FIG. 4c, the loading hinge X is unilaterally loaded from the left and the load 21 is removed from the right side. According to FIG. 4d and hinge mutually -zatížený load store 2 l ^2e from both sides of the rack £ stromečkového.

The four combinations fully exhaust all loading and unloading possibilities. 2 · The auxiliary load may consist of conventional stored material from one of the upper floors, which can only be removed temporarily to swivel the load-bearing suspension X to the required side.
