Leaf Chains are created for substantial load, slow pace tension linkage applications. Usually they may be specifi ed for reciprocating motion lifting gadgets this kind of as fork lifts or cranes. These chains are typically supplied to a specifi c length and therefore are linked to a clevis block at just about every 
end. The clevis could accommodate male ends (inside or occasionally identified as “articulating” links) or female ends (outdoors or even the links around the pin hyperlink) as needed (see illustration below)
Leaf chains can be found in three series; AL (light duty), BL (heavy duty), or LL (European normal). For new choices we endorse the BL series in preference for the AL series because the latter has become discontinued as being a acknowledged ASME/ANSI normal series chain. BL series chains are generated in accordance with the ASME/ANSI B29.eight American Leaf Chain Regular. LL series chains are created in accordance using the ISO 606 worldwide leaf chain regular.
A chain with an even variety of pitches often features a a single male and a single female finish. It’s far more widespread to get the chain possess an odd amount of pitches by which case the the two ends might be either male (most typical) or female (significantly less com-mon). When ordering lengths with an odd number of pitches male ends are provided unless of course otherwise noted. Clevis pins, typically with cotters at every end, are utilized to connect male chain ends to female clevis blocks. Chains with female ends tend to be (but not often) linked towards the clevis block having a cottered variety connecting hyperlink. The connecting hyperlink will be the female finish component in this instance.
Leaf Chain Assortment
Make use of the following formula to verify the collection of leaf chain:
Minimal Ultimate Power > T x DF x SF
T: Calculated Greatest Chain Tension
DF: Duty Element
SF: Service Aspect
Note the greatest allowable chain speed for leaf chains is 100ft per minute.
