Leaf Chains are made for high load, slow velocity tension linkage applications. Often they’re specifi ed for reciprocating motion lifting gadgets such as fork lifts or cranes. These chains are commonly supplied to a specifi c length and therefore are linked to a clevis block at each and every end. The clevis may well accommodate male ends (within or occasionally named “articulating” back links) or female ends (outside or the links over the pin hyperlink) as demanded (see illustration below)
Leaf chains are available in three series; AL (light duty), BL (heavy duty), or LL (European standard). For new selections we propose the BL series in preference for the AL series because the latter continues to be discontinued like a acknowledged ASME/ANSI standard series chain. BL series chains are made in accordance together with the ASME/ANSI B29.8 American Leaf Chain Conventional. LL series chains are produced in accordance using the ISO 606 worldwide leaf chain conventional.
A chain with an even amount of pitches usually features a 1 male and one particular female end. 
It really is extra typical to have the chain possess an odd amount of pitches during which situation the the two ends might be both male (most common) or female (much less com-mon). When ordering lengths with an odd variety of pitches male ends are supplied unless of course otherwise noted. Clevis pins, normally with cotters at every single finish, are utilised to connect male chain ends to female clevis blocks. Chains with female ends are often (but not often) connected to your clevis block by using a cottered variety connecting link. The connecting hyperlink would be the female finish component in this instance.
Leaf Chain Assortment
Make use of the following formula to verify the variety of leaf chain:
Minimum Ultimate Power > T x DF x SF
T: Calculated Optimum Chain Stress
DF: Duty Element
SF: Services Factor
Note the highest allowable chain pace for leaf chains is 100ft per minute.
