Description

The invention is bound to load-lifting devices, in particular to safety measures in the operation of cranes.

The purpose of this is to increase device reliability.

Figure 1 shows the proposed device, o.General view; FIG. 2 shows a base-to-stem connection assembly; on fig.Z - section in figure 1; Ia figure 4 - section bb in fig.Z.

The stacked load contains a rod 1 with a base 3 attached to it by an annular disk 2 and cargo elements 4 spanning the rod. , to the rod 1 by means of welds 8. In each cargo element, 4 there are radial slot 9 and first

Pencils 10 to it, in which the locking shells are placed. In addition, the cargo elements 4 have recesses 12 for the lifting loops 13. For hanging on. hook 14 of the tested crane rod 1 is equipped with a transitional link 15 with axles 6 and 17., -the assembly of goods, for testing

Noah site on the base 3 stack elements 4.

The lower cargo element, built up for four rigging loops 13, each of which is located in the recess 12, is fed laterally to

the base 3, covering the radial slot 9 rod 1. After placing the cargo element 4 on the base 3, a locking 11 is placed in the recess 10 to prevent

tea load of the load element 4. Each subsequent load element is placed on the lower part in the same order.

After the required test mass has been collected, the collected load is connected via a transition link 15, connected to the rod 1, with a hook 14 of the test crane. Attaching the rod 1 to the base 3 is carried out -

by clamping the diaphragm 7

between the annular disks 2 connected by welds 8 with the rod 1.

The implementation of the rod 1 of the varietal

steel and annular disks 2 made of sheet steel products allow a reliable weld to be made between them.

Attaching the rod 1 to the base 3 by welding the annular discs 2 makes it possible to perform the base 3 not only from cast steel, but also from other materials, such as cast iron, concrete, etc.

Claims (2)

1. MULTI-FREIGHT, mainly for testing cranes, comprising a rod with a base attached to it and covering a rod with weights with radial slots, characterized in that, in order to increase reliability, the base is made with a diaphragm having a central through hole separating each other other upper and lower nests with cylindrical side walls with circular cross sections in which annular disks are placed, rigidly connected to the barrel, and weights are made with through recesses, -conjugated perpendicular to the radial slits, and with locking inserts, the ends of which are located in the through recesses. 2. Load pop 1, distinguished by the fact that the ring discs are welded to the rod.
