Basics
1.1.2 Basic Structure of Small Pitch Conveyor Chain The basic structure is the same as that of power transmission chain. Figure 1.4 shows a single pitch conveyor chain. The double pitch type in Figure 1.5 has an outer plate and an inner plate of the same height, but often has a roller with a larger diameter. Usually, an attachment is used with this chain.

1.1.3 Basic Structure of Large Pitch Conveyor Chain—Engineering Class Large pitch conveyor chain has the same basic structure as double pitch con- veyor chain (Figure 1.5), but there are some differences. Large pitch conveyor chain (Figure 1.6) has a headed pin, sometimes a flanged roller (F-roller), and usually does not use a riveted pin. Large pitch conveyor chain is also called engineering class chain.
1.1.4 Functions of Chain Parts Plate
The plate is the component that bears the tension placed on the chain. Usually this is a repeated loading, sometimes accompanied by shock. Therefore, the plate must have not only great static tensile strength, but also must hold up to the dynamic forces of load and shock. Furthermore, the plate must meet environmental resistance requirements (for example, corrosion, abrasion, etc.).
