FIELD OF THE INVENTION The invention relates to a lifting and transport machinery, namely, running gears of bridge type cranes.

The purpose of the invention is to improve the ease of operation of the chassis.

Figure 1 shows the suspension part of the crane type bridge, general view; figure 2 is the same, top view; on fig.Z - section aa in figure 1; and figure 4 - section bb in figure 1.

The suspension part of the bridge-type crane contains a box-shaped girder 1, inside which a wheel 2 is installed, made with a hub 3. Vertical plates 4 are located between the side walls of the beam 1 and the wheel 2. Glasses 5 are made on one side with a flange 6, and on the other side bearings 7 are installed. The side walls of the beam and the plate 4 are made with coaxially arranged and reinforced pads 8 holes 9 in which the glasses 5 are mounted. The hub 3 of the wheel 2 is made with cylindrical parts 10 on which the bearings 7 are fastened. Tina 4 is made C-shaped and connected to the horizontal and corresponding lateral 12129152

the outer walls of the beam 1, the end 11 of which, in the part located in front of the wheel 2, is made with a cut-out closed by a removable plate 12 with a buffer 13. The wheel 2 can be connected to the drive mechanism 14. 5 The suspension part of the crane of the bridge type works as follows.

The pressure from the wheels 2 is transmitted through the bearings 7 to the sleeves of the cups 5, through them to the vertical plate 4 and 10 of the wall of the box girder 1.

To roll out Ko. ieco 2, it is necessary to remove the plate 12 with buffer 13 and remove the sleeves of the cups 5.

Thus, in the proposed construction, due to the installation of C-shaped 15 plates 4, the sleeves of the cups 5 rest on two walls, which ensures high rigidity of their installation and does not require a powerful developed flange 6 for fastening to the beam 1. This in turn allows the cup 5 to be made with a detachable flange 6, which serves only as an element allowing the cup 5 to be attached to the beam 1. As a result, the walls of the beam 1 that are attached to the flange 6 of the upper wall do not require additional machining.
