The invention relates to lifting equipment, namely, lifting beams.

A known lifting beam with a rotatable working body, supporting vertical platforms, traversing arms located on opposite sides, ti, one ends of which are hinged on brackets, and elements for mounting it on the lifting body of the crane Ll. . A disadvantage of the known lifting beam is comparatively low reliability when performing technological operations between the ladders.

The purpose of the invention is to increase the reliability of technological operations between the racks.

The goal is achieved by the fact that a lifting beam, containing a rotary working body, supporting vertical platforms, located on opposite sides of the crossbeam, one ends of which are hinged on brackets, and elements for hanging it on the crane lifting body, the crosshead is fitted with horizontal guides attached to it , sliders installed in the said guides and pivotally connected to the other ends of the tg, blocks with flexible bodies mounted in the upper part of the sliders, retractors with counterweights located respectively with the outer and inner parts of the sliders and flexible organs suspended from the ends, and drive-mounted kinematic pairs of screw-nuts located perpendicular to the direction of movement of the supporting vertical platforms mounted on the carriages, while the brackets are fixed on the nuts of the kinematic pairs.

Figure 1 shows gruzozahvatg-, on the traverse, a general view; Figure 2 is the same, top view,

The lifting beam of the traverse contains a rotary working body 1, supporting verticals 2 platforms, traversing arms located on opposite sides, ti 3, one ends of the cat & 410632

fastened on brackets 4 mounted on drive-mounted kinematic pairs 5 of screws-nuts, and the other ends of the t h are hingedly connected with 5 sliders 6 installed in

i horizontal guides. In the upper part of the sliders 6 are mounted blocks 8, covered by a flexible body

9, on the ends of which are hung from 0 the outer side of the slide 6 carriage

10, ac internal - a counterweight 11. On the carriages 10 the support platforms 2 are mounted. On the traverse there are elements for mounting it on the crane lifting body (not shown). The traverse is designed to work in the racks 12, on which the pallets 13 are installed.

Grab traverse works

0 as follows.

Traverse using a crane is lowered into the opening between the racks 1 2 to the specified rack 1 2 with the pallet 13, then turn on the drive kinematic

5, pair 5 and slide the slides 6 up to the stop of the platforms 2 in the racks 12. The traverse is fixed from lateral movement. Push the working body 1 under the pallet 13 and

0, using a crane, raise the traverse until the body 1 lifts the pallet 13 above the rack 12, while the carriages 10 with the platforms 2 remain stationary and continue to fix

5 to the traverse from lateral displacement, and the raising of the traverse is provided by its movement upwards relative to the stationary carriage 10. After moving -. no pallet I3 in traverse dimension

d, drive pair 5 shifts slides

6 inside the crosshead and the latter is lifted by a crane from the opening between the racks 12. Similarly, the cross bar works when lowering the pallet 13 on the racks 12.

Thus, lifting capacity. the traverse can work in the opening between the racks, has lateral fixation relative to the racks and can

g at the same time to make technological movements in the vertical direction, which increases the reliability of operation of the traverse in the inter-shelf space. g 1 3
