ABSTRACT
The common ‘flexible track belt’ system that is mounted on many bulldozers or tractors comes in two general mechanical engineering styles. In the first style, only up-down movements of a track plate that spans between mutually connected road rollers can occur. This arrangement is as shown in Figure 6.1. In the second structural configuration or style, up-down and side-side movements of road rollers that are mutually connected by hinges, springs or torsion bars can occur. This second style is shown in Figure 6.2. In general, the flexible track system is appropriate for construction work that must take place on or over terrains that are geometrically rough or which are full of ups and downs.
