Leaf Chains are manufactured for higher load, slow pace tension linkage applications. Normally these are specifi ed for reciprocating motion lifting units such as fork lifts or cranes. These chains are ordinarily provided to a specifi c length and are connected to a clevis block at every single end. The clevis may perhaps accommodate male ends (inside or often referred to as “articulating” back links) or female ends (outside or even the links on the pin link) as required (see illustration under)
Leaf chains can be found in 3 series; AL (light duty), BL (hefty duty), or LL (European conventional). For new selections we advocate the BL series in preference on the AL series as the latter is discontinued as being a acknowledged ASME/ANSI conventional series chain. BL series chains are generated in accordance together with the ASME/ANSI B29.8 American Leaf Chain Common. LL series chains are created in accordance with the ISO 606 global leaf chain typical.
A chain with an even number of pitches generally includes a one male and one female finish. It is actually a lot more frequent to get the chain possess an odd number of pitches by which situation the both ends are going to be either male (most typical) or female (less com-mon). When ordering lengths with an odd variety of pitches male ends are provided except if otherwise noted. Clevis pins, commonly with cotters at every finish, are used to connect male chain ends to female clevis blocks. Chains with female ends tend to be (but not usually) connected on the clevis block with a cottered kind connecting link. The connecting hyperlink is definitely the female finish component in this case.
Leaf Chain Assortment
Use the following formula to verify the collection of leaf chain:
Minimum Ultimate Power > T x DF x SF
T: Calculated Greatest Chain Stress
DF: Duty Factor
SF: Support Component
Note the optimum allowable chain velocity for leaf chains is 100ft per minute.
