Gnawing rail bridge crane

Bridge crane is lifting the main types of equipment, the use is widespread, special equipment is included in the national governance, the quality of its running state has a direct impact on production safety.  overhead bridge crane  in use after a certain time, or run the prerequisite conditions frequently, will emerge at different levels gnawing rail carts run phenomenon, ranging from decreased effectiveness of the work equipment, increased protection workload and operating costs while in lead safe now suffering, bring their own issue and devices incident, based on many years of testing and actual crane work for gnawing rail  bridge gantry crane  to explore the phenomenon analyzed, and the corresponding solutions.

Gnawing track "scene
Usually crane wheels between the side edge of the rail is designed with a certain clearance, in normal operating conditions, they do not touch. But sometimes the wheel is not in the center of the running track, which occurred in the wheel rim in contact with the side of the track (Mount wipe) the gnawing rail phenomenon.
Crane testing process, if found running crane rail of the following signs to confirm cranes of varying degrees of "bite track."
(A) the crane in operation, special in starting, braking body deviate twist Akira, sometimes bigger sound.
(2) traveling  overhead gantry crane  in the rail flange due to the gap interval changes are obvious.
(3) side of the track there is a crystal traces of severe and deep groove-shaped burr grinding marks.
(4) There are bright spots inside the wheel rim and a burr, graders.
(5) will be issued when the carts did not run over a loud "hissing" sound bite rail, stern when running carts will bring them out, "Hang Hang" the rattle, even showing derailment.
