Repair of track shoes

Jan 12,2022

The wear of the track shoe mainly has two parts: the raceway surface and the track pin hole. It is very simple to repair. After the raceway is worn, a groove sags, and when the depth does not exceed 2~3 mm, it can be directly repaired by surfacing welding. When the wear is deep, steel bars of different sizes can be filled in the grooves according to the specific conditions, and then welded from all sides. The pin hole should be restored to its original size and the center position of the original hole after grinding. To do this, cut the worn pin hole, insert a standard size pin, then heat it to about 800 ℃, and then roll up the edge of the ear. Add a semi-circular iron plate to the outside of the incision and weld it firmly with electric welding. The track shoes thus repaired can last for more than 100 shifts
