Abstract
An improved apparatus for rebuilding worn shoe grouser for track chain by welding operation is disclosed. The worn part of shoe is cut off and replacement lug is placed on grouser so that the welding end face of the former comes in tight contact with the welding end face of the latter while they are held between the lug holding member and the shoe holding member. The shoe holding member is adapted to move forward and backward via a shoe supporting member by means of a hydraulic cylinder and the whole assembly of hydraulic cylinder, shoe supporting member, shoe holding member and lug holding member is turnable about the axis of rotary shafts by actuating the turning mechanism. While replacement lug and grouser are brought in firm contact with one another, welding operation is carried out over the one welding area on shoe to be rebuilt. After completion of welding operation the turning mechanism is actuated by rotating a handle so that the whole assembly is turned upside down whereby another welding operation is carried out over the other welding area. The lug holding member is formed with a groove on the one side into which replacement lug is fitted, while it includes a rotary shaft on the other side so that the assembly can be turned. Plural combinations of lugs and grousers may be arranged one after another with spacers interposed therebetween.
