Commonly used track shoes are divided into three types according to the grounding shape, there are single-reinforced, three-reinforced and flat-bottomed, and some of them also use triangular track shoes. Single-reinforced track shoes are mainly used for bulldozers and tractors, because this type of machinery requires the track shoes to have a higher traction capacity when working. However, it is rarely used on excavators. This type of track shoe is only used when the excavator is equipped with a drill frame or requires a large horizontal thrust. A higher traction is required when turning from a child, so a higher crawler bar (ie crawler spike) will squeeze away the soil (or ground) between the crawler bars, thereby affecting the mobility of the excavator.
Steel track shoes can be divided into: excavator plates and bulldozer plates. These two are the most commonly used, using section steel as the raw material. Then there is the wet floor used by bulldozers, commonly known as "triangular plates", which are cast plates. Another cast slab is used on crawler cranes. The weight of this slab can be as little as tens of kilograms, and as many as hundreds of kilograms.
