Applications
1.6.2Leaf Chains Lifting, counterbalance, forklifts, machine tools
Application Examples Leaf Chains are used for fork lift masts, as balancers between head and counterweight in machine tools, or for low-speed pulling (tension linkage). This type of chain is also called “Balance Chain,” and is regulated by ANSI B29.8M, JIS B 1804, and ISO 4347. (See Figure 1.23.)
Figure 1.23 Leaf Chain and a Leaf Chain Application
Construction and Features These steel chains have a very simple construction: link plates and pins. The chain number indicates the pitch and the lacing of the links. (See Figure 1.24.) The chains also have the features shown below. (1) High tensile strength per section area. This allows the design of smaller equipment. (2) There are A- and B-type chains in this series. Both AL6 Series and BL6 Series have the same chain pitch as RS60 (19.05 mm), but they differ, as shown in Table 1.10. (3) These chains cannot be driven with sprockets. Sprockets Sheaves, not sprockets, are used to change the direction of these chains (Figure 1.25).
