The invention relates to a lifting and transport machinery, and it is related to the attachment points of the traveling wheel to the end beam of a crane.

The purpose of the invention is to simplify the cd structure.

FIG. 1 shows the mount of the traveling wheel to the end beam, general view; -on FIG. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 shows a section B-B in FIG. one; in fig. 5 is a section of YYD in FIG. one.

The mount of the traveling wheel to the end beam of the crane contains an end beam 1 in which the driving wheels 2 are mounted on shafts 3, 4 and are supported on bearings 5 mounted in cups 6, which are mounted by fitting in annular grooves 7 made in lining 8, welded from the outer sides to the walls of the end beam 1. The fixing of the cups 6 to the plates 8 is provided with bolts 9. Bearings 5 are protected from dirt and dust on the outside by covers 10, and from the inside by covers 11. In the walls of the end beam 1 and, accordingly, on hordes 8 are provided with horizontal grooves 12 intended for outputting shafts 3, 4 with driving wheels 2, bearings 5, cups 6 and lids 11.,

Kinematically, the drive wheel 2 (Fig. 2) is connected via shaft 3 with the mounted gearbox 13 and the engine 14. At the same time, the gearbox 13 is kept from rotation by a bracket 15 attached to the upper hl of the end beam 1.

Similarly mounted on the shaft 4 non-driving chassis 2

(Fig. 4).

At the ends of the end beam 1, the scrapers 17 and the buffer 18 are fastened with bolts 16, and the glasses 6 are provided with squeezing holes 19.

To dismantle the chassis of the crane, unscrew the bolts 16 and remove the buffer 18 and scrapers 17. Unscrew the bolts 9 and remove the covers 10. Screw the bolts 9 into the release holes 19 of the cups 6 (Fig. 5) and pull them out of the annular grooves 7. Roll out in the direction of the open horizontal groove 12 running wheel assembled with shaft 3 or 5 shaft 4, bearings 5, cups 6 and covers 11. When removing the drive running wheel, it is necessary to disconnect the reducer 13 from the bracket 15.
