How to determine whether the crane traveling wheels gnawing rail

Traveling crane, also known as overhead crane or traveling crane, mainly across the factory building and other frames between the operation, it has a role in the implementation of various types of processes. The quality of its operation to ensure that enterprises will be prompted to obtain better economic operating results. So how to determine whether the crane wheel gnawing rail? Traveling car wheels gnawing rail is the wheel rim and track side of the intense friction, resulting in wheel rim and track side damage, which will make available more than ten years of wheel damage in a few months, but also due to the gnawing of the rail increased running resistance, resulting in the traveling car walking mechanism of the electro-mechanical components, service life is reduced, the track is deformed, loose, and in serious cases, but also affects the strength of the structure of the plant changes. Traveling car gnawing rail causes, can be a unilateral cause, can also be a combination of reasons caused by a variety of aspects, there are also track installation quality problems caused by. Here we will analyze how to determine whether the crane traveling wheel gnawing rail.
How to determine whether the crane traveling wheel gnawing rail
Whether the bridge crane trolley gnawing rail occurs in the work, from the following points to judge:
There is a bright trace on the side of the rail, and there is a burr on the trace when it is serious.
There is a bright spot on the inside of the wheel rim.
When the crane is traveling, there is a significant change in the wheel rim and track clearance within a short distance.
Crane in operation, especially when starting and braking, the car body deviation, twisting and swinging.
Gnawing rail is particularly serious when it will issue a hissing sound or louder utterance of the gnawing sound.
There are bright spots on the top surface of the track.
Crane rail gnawing can be divided into 3 levels:
Crane traveling wheels light gnawing rail
Controller handle to put 1 gear when the crane does not start, 2 gear start, stop the inertia of the running (not braking) distance is short, the rim of the wheel wear is slow, there is no chip, crimping phenomenon, wheel service life of 2 to 3 years.
Crane traveling wheels gnawing on rails
The crane does not start when the controller handle is put in 1st gear, starts slowly in 2nd gear, stops sometimes without inertia running or running distance is very short, the rim of the wheel wears fast and has curled edges, the service life of the wheels is 0.5～1 year.
