Crane Rail Gnawing Reasons

Crane Rail Gnawing Reasons


Crane Rail Gnawing Crane Rail Gnawing 2

1.Crane brake itself - we all know that when the crane started braking , it will definitely have a considerable driving forces, if the crane traveling and trolley traveling simultaneously, it will cause the crane traveling (longitudinal traveling) and trolley traveling (traversing traveling) to produce a synthetic system power, in this case, it will inevitably lead to discontinuity on the whole track, if the track itself is installed when there is a level difference, the crane center overall tilt in the other side, it cause the lower side of the crane bear more stress, resulting in the phenomenon of crane gnawing rail.

2. The reason of the wheels - the wheel itself when manufactured, existing different sizes of the left and right side, in this case, during the crane traveling, because of the fast speed, the larger-diameter side walking ahead will ultimately lead to the distortion and bending of the wheel.

3. The reason of the track - in fact, we cannot rule out the reason of the track itself, due to the installation of the track itself, does not comply with the relevant rules and related parameters, resulting in a larger tolerance of span, finally resulting in the crane wheel rail gnawing.
