Leaf Chains are produced for large load, slow speed stress linkage applications. Often they can be specifi ed for reciprocating motion lifting gadgets such as fork lifts or cranes. These chains are generally supplied to a specifi c length and therefore are connected to a clevis block at each and every finish. The clevis may possibly accommodate male ends (within or sometimes referred to as “articulating” backlinks) or female ends (outdoors or even the links on the pin website link) as expected (see illustration beneath)
Leaf chains are available in 3 series; AL (light duty), BL (hefty duty), or LL (European typical). For new selections we suggest the BL series in preference towards the AL series as the latter continues to be discontinued as a recognized ASME/ANSI normal series chain. BL series chains are developed in accordance with the ASME/ANSI B29.8 American Leaf Chain Normal. LL series chains are created in accordance using the ISO 606 international leaf chain typical.
A chain with an even number of pitches generally includes a 1 male and one female finish. It really is much more widespread to get the chain possess an odd quantity of pitches by which case the both ends is going to be both male (most common) or female (much less com-mon). When ordering lengths with an odd amount of pitches male ends are provided unless otherwise noted. Clevis pins, normally with cotters at every end, are utilized to connect male chain ends to female clevis blocks. Chains with female ends are frequently (but not constantly) linked on the clevis block which has a cottered style connecting website link. The connecting link may be the female end part in this instance.
Leaf Chain Selection
Make use of the following formula to verify the collection of leaf 
chain:
Minimum Greatest Power > T x DF x SF
T: Calculated Maximum Chain Tension
DF: Duty Factor
SF: Support Issue
Note the highest allowable chain velocity for leaf chains is 100ft per minute.
