Talking about the Excavator undercarriage for track shoe

Track shoe The track shoe is one of the chassis parts of construction machinery, and is a wearing part of the construction machinery used. It is now commonly used in construction machinery such as excavators, bulldozers, crawler cranes, and pavers. Crawler shoes, use: excavators, bulldozers, crawler cranes, etc. Nature: chassis parts of construction machinery Material: Steel and Rubber Structure: The track shoes on construction machinery come from materials, which can be divided into: steel and rubber. Steel track shoes are mostly used on equipment with relatively large tonnage, and rubber track shoes are mostly used on equipment with small tonnage. Classification: Steel track shoes can be divided into: excavator shoes, bulldozer shoes, these two are the most commonly used, with section steel as the raw material. Then there is the wet floor used by the bulldozer, commonly known as “triangle plate”, which is a cast plate. Now a large number of cast plates are used for crawler cranes. The weight of this plate can range from tens of kilograms to hundreds of kilograms. The plate of Sany Heavy Industry’s SC10000 crawler crane at the 2008 Shanghai Bauma Exhibition, It is more than 800 kilograms, which is currently the heaviest track shoe in China. Processing method: The processing technology of the track shoe of the profile is generally: using the profile blanking, drilling (punching), heat treatment, straightening, painting and other processes, the board of the bulldozer is single-reinforced, and the general paint color is yellow; excavation; The machine board is generally three-rib, and the paint color is black. The material of the profile is generally purchased now is 25MnB, and the final heat treatment hardness of the material is HB364-444.   Folding heat treatment: The heat treatment of track shoes is a very complicated process, and diathermy forging is the most important process in all heat treatment processes. The diathermy forging of the track shoe (diathermy is the overall heating of the metal from the outside to the inside, which is the heat treatment before the metal forging) can be completed by selecting an intermediate frequency induction heating furnace.
