Leaf Chains are made for substantial load, slow velocity stress linkage applications. Usually they are really specifi ed for reciprocating movement lifting products such as fork lifts or cranes. These chains are typically provided to a specifi c length and are linked to a clevis block at each and every end. The clevis might accommodate male ends (within or at times known as “articulating” links) or female ends (outside or the links on the pin website link) as essential (see illustration below)
Leaf chains can be found in 3 series; AL (light duty), BL (heavy duty), or LL (European typical). For new selections we propose the BL series in preference to your AL series because the latter has been discontinued as a acknowledged ASME/ANSI normal series chain. BL series chains are created in accordance with all the ASME/ANSI B29.8 American Leaf Chain Common. LL series chains are developed in accordance with all the ISO 606 global leaf chain conventional.
A chain with an even number of pitches constantly features a one particular male and one female finish. It truly is additional common to possess the chain possess an odd amount of pitches through which situation the both ends will likely be either male (most common) or female (much less com-mon). When ordering lengths with an odd number of pitches male ends are supplied unless otherwise mentioned. Clevis pins, usually with cotters at each end, are employed to 
connect male chain ends to female clevis blocks. Chains with female ends tend to be (but not usually) linked to the clevis block which has a cottered variety connecting link. The connecting link could be the female end component in this instance.
Leaf Chain Assortment
Use the following formula to verify the selection of leaf chain:
Minimal Ultimate Power > T x DF x SF
T: Calculated Greatest Chain Tension
DF: Duty Factor
SF: Services Factor
Note that the highest allowable chain speed for leaf chains is 100ft per minute.
