How to judge whether the bridge crane wheel gnaws the rail?

Everyone knows that crane gnawing on rails is a more serious matter. If you don't pay attention, it will often lead to more serious consequences. So early to find out whether the crane is gnawing the rail is obviously more important. How to judge whether the bridge crane wheel is gnawing on the rail?

Under normal conditions, a certain gap is designed between the wheel flange and the side of the track, and under normal operating conditions, they will not touch. When gnawing occurs, the two come into contact. In the previous article, we talked about the causes and hazards of rail gnawing by bridge cranes , and today we will introduce how to judge whether or not to gnaw rails.

The manifestations of bridge crane wheel gnawing phenomenon include:

• (1) There are scars on the side of the track or the inner side of the wheel rim. In severe cases, there are burrs or iron scraps on the marks.
• (2) When the bridge crane is traveling, the gap between the wheel flange and the track changes significantly within a short distance.
• (3) During the operation of the bridge crane, the car body skews and the wheels deviate.
• (4) When the cart is running, it will make a louder "hissing" gnawing sound.
• (5) When the rail gnawing is particularly serious, the cart will make a crashing sound or even crawl on the rail.

The above is a relatively obvious phenomenon, which has a great effect on helping us to judge whether the crane is gnawing on the rail.

Rail gnawing degree of bridge crane

• (1) Slightly gnaw rails. The controller starts slowly in the first gear, and the inertial running distance is short after stopping.
• (2) Moderate gnawing. The controller does not start in the first gear, and the second gear starts slowly. When stopping, sometimes it runs without inertia, the wheel flange wears quickly, and there is curling.
• (3) Severely gnaw rails. The second gear of the controller does not start, and within l0m of reverse operation, the vehicle body skew reaches the maximum value and starts to gnaw the track.

We know that the hazards of bridge cranes gnawing rails are more serious, so it is necessary to strengthen the maintenance of cranes to find and solve problems in time.
