Leaf Chain – Standard Information and Assortment

Leaf Chains are made for large load, slow velocity tension linkage applications. Typically they are specifi ed for reciprocating movement lifting devices such as fork lifts or cranes. These chains are commonly supplied to a specifi c length and are connected to a clevis block at every single finish. The clevis may accommodate male ends (within or in some cases called “articulating” back links) or female ends (outside or the backlinks over the pin website link) as required (see illustration beneath)
Leaf chains are available in 3 series; AL (light duty), BL (heavy duty), or LL (European typical). For new choices we suggest the BL series in preference towards the AL series as the latter has become 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 with all the ISO 606 international leaf chain common.
A chain with an even variety of pitches generally features a one male and a single female end. It is actually additional widespread to get the chain possess an odd amount of pitches during which situation the both ends might be both male (most common) or female (less com-mon). When ordering lengths with an odd amount of pitches male ends are supplied unless of course otherwise mentioned. Clevis pins, typically 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 generally) linked for the clevis block which has a cottered style connecting link. The connecting website link will be the female end component in this case.
Leaf Chain Variety
Utilize the following formula to verify the choice of leaf chain:
Minimum Greatest Power > T x DF x SF
T: Calculated Maximum Chain Tension
DF: Duty Issue
SF: Service Element
Note that the maximum allowable chain velocity for leaf chains is 100ft per minute.
