The invention relates to load gripping devices, in particular, traverses d,; 1 Dia. 1, and NPO mee | 1 and s.

Known traverse pp llinnomern1) 1 Izlel comprising nesun1y e.lemept with foupzhnoy pp 11aven1ivani sruzonolemnogo mechanism to hook blocks novorotno mounted on the axes x, zakrenlennyh on the support member symmetrically with respect to its vertical axis, and the lines with envelopes blocks bodies for means of handling 1 ends .

A disadvantage of the known cross bar is the relatively low reliability caused by the absence of fixation of the slings on the blocks of the cross bar.

The purpose of the invention is to increase reliability.

The goal is achieved by the fact that in the traverse for lengthy products containing a nonsunny element with a different one for hanging on the hook of the lifting mechanism, blocks newly mounted on the axes fixed on the supporting element symmetrically about its vertical axis and the envelopes of the blocks with load gripping bodies on the ends, the axes of the blocks are fixed on the carrier, the element by means of wire ropes with the possibility of vertical movement and are spring-loaded in the vertical direction, and the traverse is provided with gaskets fixed by on the bearing element, between the crown clamps, with the possibility of mutual action with the blocks, while the blocks and gaskets are made of friction material.

FIG. Figure 1 shows schematically a traverse with blocks of friction material mounted on a bearing element; in fig. 2 - the same, with the blocks installed under the bearing part; in fig. 3 node I of FIG. one; pas figs. 4 shows section A-A in FIG. one.

FIG. 2

On a nonsunked element 1 (beam, frame), a nylon of 2 is fixed for visiting the hook of a lifting mechanism and brackets 3 with blocks 4 (FRG 1 and 2) are located symmetrically relative to the vertical axis of the bearing element at ends of D .1I seize cargo 6.

The axis 7 of block 4 (figs. 3 and 4) is mounted on brackets 3, which are attached to the supporting element 1. Axis 7 is spring-loaded in the vertical direction by springs 8 and has the possibility of vertical movement in the slots 9 of the royshchteyn 3. Between the brackets 3 on the supporting element 1 is fixed gasket 10. Block 4 and gasket 10 are made of friction material. The block 4 is provided with a groove 1 1 for bending around the sling.

Traverse works as follows.

0 When the load-lifting mechanism lifts the crossbeam with a load in blocks 4, the tension of the straps 5 is inoperative, as a result of which the blocks 4 begin to rotate. On this, on each block 4, under the action of springs 8, tension is equalized in both straps. The tension alignment is stopped when the traverse with the load-line is reached due to the termination of rotation of the blocks 4 of friction material as a result of braking while pressing them against the gaskets 10 of friction material.

Upon delivery of the load to the place and removal of the slings 5 from the product, the blocks 4 are returned to their original (inoperative) position, and the traverse can be used for lifting and transporting subsequent loads.

The invention improves production efficiency and product quality, drastically reduces damage during demolding and transportation of reinforced concrete and other products.
