Leaf Chains are manufactured for higher load, slow speed stress linkage applications. Generally they are specifi ed for reciprocating movement lifting products such as fork lifts or cranes. These chains are usually provided to a specifi c length and therefore are linked to a clevis block at each and every finish. The clevis could accommodate male ends (within or in some cases named “articulating” back links) or female ends (outdoors or even the links over the pin website link) as expected (see illustration below)
Leaf chains are available in 3 series; AL (light duty), BL (hefty duty), or LL (European normal). For new choices we advise the BL series in preference on the AL series since the latter has been discontinued as being a recognized ASME/ANSI common series chain. BL series chains are generated in accordance with all the ASME/ANSI B29.8 American Leaf Chain Common. LL series chains are generated in accordance using the ISO 606 global leaf chain common.
A chain with an even quantity of pitches always has a one male and one female end. It is actually extra popular to possess the chain possess an odd amount of pitches through which case the both ends will probably be either male (most typical) or female (significantly less com-mon). When ordering lengths with an odd variety of pitches male ends are supplied unless otherwise noted. Clevis pins, typically with cotters at each end, are employed to connect male chain ends to female clevis blocks. Chains with female ends are frequently (but not normally) connected to the clevis block that has a cottered kind connecting website link. The connecting website link will be the female finish component in this instance.
Leaf Chain Assortment
Make use of the following formula to confirm the selection of leaf chain:
Minimum Ultimate Strength > T x DF x SF
T: Calculated Greatest Chain Tension
DF: Duty Issue
SF: Services Element
Note the maximum allowable chain speed for leaf chains is 100ft per minute.
