Leaf Chain – Standard Information and Choice

Leaf Chains are manufactured for higher load, slow velocity tension linkage applications. Usually they are specifi ed for reciprocating motion lifting devices such as fork lifts or cranes. These chains are generally supplied to a specifi c length and are connected to a clevis block at every single finish. The clevis may perhaps accommodate male ends (inside or in some cases termed “articulating” back links) or female ends (outside or the hyperlinks over the pin website link) as required (see illustration below)
Leaf chains are available in 3 series; AL (light duty), BL (heavy duty), or LL (European normal). For new choices we suggest the BL series in preference to the AL series since the latter continues to be discontinued like a acknowledged ASME/ANSI common series chain. BL series chains are developed in accordance using the ASME/ANSI B29.8 American Leaf Chain Normal. LL series chains are produced in accordance using the ISO 606 international leaf chain common.
A chain with an even variety of pitches generally features a one male and 1 female end. It is actually far more widespread to get the chain possess an odd quantity of pitches during which situation the both ends will likely be both male (most common) or female (less com-mon). When ordering lengths with an odd variety of pitches male ends are supplied unless otherwise mentioned. Clevis pins, generally with cotters at every single end, are employed to connect male chain ends to female clevis blocks. Chains with female ends are sometimes (but not often) linked for the clevis block which has a cottered style connecting link. The connecting website link will be the female end part in this case.
Leaf Chain Variety
Utilize the following formula to verify the variety of leaf chain:
Minimum Greatest Power > T x DF x SF
T: Calculated Maximum Chain Tension
DF: Duty Issue
SF: Service Aspect
Note that the maximum allowable chain velocity for leaf chains is 100ft per minute.
