Crawler-type construction machinery must choose different track shoes in different operating environments, so as to improve the efficiency of mechanical operations and maximize its performance.

　　Loading and snow digging operations. It is advisable to use semi-double-tooth grouser shoes. The height of the grousers is between the single-tooth and three-tooth grouser shoes. There are two grousers with unequal heights, which have the characteristics of large traction and can prevent frequent turns. This kind of grouser has a large thickness. It has high torsion and bending strength under heavy load, but the disadvantage is poor ride comfort on hard ground.

　　Wetland track shoes and snow track shoes should be used on wetland and snow respectively. The cross section of the wetland track shoe is 3 arcs, with large grounding area, large buoyancy, no tooth tip, and will not cut any objects on the ground; there are special arc sections at both ends to prevent sideslip. The disadvantage is that it is low in strength and easy to deform, so it is not applicable except for wet ground. The snow track shoe has ribs, and the grousers have steps to prevent side slip. The trailing edge of the board surface is cut off, which is easy to squeeze out the ice and snow remaining on the track shoe. If used in ordinary soil and rocks, the track is easy to wear or damage.

　　Working in special environments such as paving. Flat track shoes and rubber track shoes can be used for paving stone roads and paved roads. The former has no crawler teeth and the bolt head is lower than the board surface, which will not damage the road or the ground when walking or working; the latter is to fix the rubber block on the ground surface of the crawler shoe, when the machine is walking, it does not damage the road surface and there is no noise when crawling; It is that their scope of application is limited. If processing high-temperature slag, use slag to treat track shoes, which are characterized by high heat resistance, high strength and long life, and can also be used for stonework.
