They are commonly used in construction machinery such as excavators, bulldozers, crawler cranes, and pavers. Commonly used track shoes are divided into three types according to the ground contact shape: single-rib, triple-rib and flat-bottom. Some of them also use triangular track shoes. The track shoes on construction machinery can be divided into steel and rubber based on the material. Steel track shoes are mostly used on equipment with relatively large tonnage, and rubber track shoes are mostly used on equipment with small tonnage.

[0003] Its application number "CN202021742080.5" discloses "a wear-resistant bottom-fixed rubber track shoe", which "comprises a track shoe body, connecting blocks are fixedly connected to both sides of the bottom of the track shoe body, bolts are fixedly connected to the bottom of the connecting blocks, limiting holes are provided on both sides of the bottom of the track shoe body, the track shoe body comprises a base layer, a protective layer is fixedly connected to the top of the base layer, a protective layer is fixedly connected to the top of the protective layer, the protective layer comprises a first wear-resistant layer, and a second wear-resistant layer is fixedly connected to the top of the first wear-resistant layer".
