The crane truck walked in a wrong way
The cause of the wheel gnawing Single-girder crane wheel rail gnawing occurred reasons or more, hoisting machinery co., LTD in anhui think is probably the wheel, wheel installation position is not very accurate, for example, exist in the process of machining error of the wheel and so on the related problems of the wheel will eventually lead to the wheel rail gnawing phenomenon. There is also the possibility that the cause of the orbit will cause the wheels to chew the rails. The orbital quality of the car and the quality of the installation are poor, and the track is not straight enough to be on the rails. If two orbit if elevation is no longer the same horizontal plane, can cause the crane transverse rupture occurred during normal operation of the process, thus resulting in the wheel rail gnawing phenomenon. If the car is orbit with the materials such as oil and water will make the whole car rail is better, so single-girder crane cart in orbit is very likely to lead to tilt when I was walking around and produce the phenomenon that gnaw rail. These are the problems that cause the wheel to gnaw. In addition to the above mentioned reasons of wheel and rail, and deformation of the bridge and the corresponding transmission device of large error and so on will cause the wheel rail gnawing phenomenon occurred.
The related inspection method of the wheel gnawing Relatively simple method is visual, www.qzj99 if found traces of rail surface has obvious bright, even hairy scar, or is the edge of the wheels have a bright spot, that might have occurred wheel rail gnawing phenomenon; If running in normal single-beam crane, wheel and track all of a sudden a very obvious changes have taken place, the crane is the wheel rail gnawing phenomenon; If the crane to start or braking, crane body had the obvious inclined or twist phenomenon, is also causes the wheel rail gnawing.
Measures to prevent the wheel gnawing It is possible to prevent the wheel gnawing by limiting the ratio between the span of the single beam crane bridge and the ratio between the wheelbase. Can also be used between the orbits of the wheel rim and the corresponding coupled with lubricating oil, which can effectively reduce the whole operation of the friction, and finally reduce the wheel wear, and so on to prevent wheel gnawing rail; In addition, anhui crane machinery co., LTD. Is a more direct method to check the relevant equipment in time.
Single-girder crane cart wheels in the process of the running of the crane, the edge of the wheel and rail is very tight, so as to make the normal operation of the resistance increasing, which eventually led to the edge of the wheel of the cart and the corresponding rail with related wear phenomenon is what we usually call related to gnaw rail phenomenon. The occurrence of this phenomenon will make the single-beam crane wheels and the corresponding rail use of life is there will be largely reduced, otherwise there will be make the crane the risk of derailment, serious still can cause of deaths and injuries. According to the experience of single beam crane, anhui crane machinery co., LTD. Summarizes the relevant reasons and corresponding measures for the wheel gnawing.
