Requirements for wagons to use

The most common fault is the formation of different trucks cracks in detail. So when servicing cars requires careful examination of parts trucks and replace them if necessary.

In the freight car bogie cracks are most likely to thrust bearing, vertical and horizontal walls bolsters thrust zone, in the side frames. In the latest cracks may mainly in the corners of box and spring openings, in an oblique, the upper and lower areas in the columns in the tide for roller brake shoe hangers, etc.

In trolleys UVZ that lack cross-connection, there cracks in the vertical walls with bolsters of the hole under the bolts to hold the relief angles triangelya incident on the way. In trolleys CRI-X3-0 and triaxial fracture may also supports skolzunov, while biaxial MT 50 and UVZ - in boxes skolzunov and liner.

During the inspection and repair of triaxial carts should pay attention to the state of balance beams, pivot beams, shells friction shock absorbers, which can cause cracks in service. Bolts connecting the pivot beam with a bolster or transverse, should all be in place and be slack in the range of 10-15 mm to allow for "Quitting" frame in a vertical plane.

In trolleys CRI-HZ-0 is not allowed a break or crack in the wedge friction damper, the absence or break skolzuna cap or bolt fastenings, and three-axle bogies - bar skolzuna

In the four-axle trucks, in addition to troubleshooting specific to trucks CRI-A3-0, cracks can occur in connective beam in an area of skolzunov, pyatnikov and the central thrust. When detecting such cracks car must be uncoupled.
