Leaf Chains are manufactured for substantial load, slow speed tension linkage applications. Generally they are really specifi ed for reciprocating motion lifting gadgets this kind of as fork lifts or cranes. These chains are typically supplied to a specifi c length and therefore are connected to a clevis block at just about every end. The clevis may well accommodate male ends (inside or from time to time termed “articulating” back links) or female ends (outside or even the hyperlinks over the pin link) as needed (see illustration below)
Leaf chains are available in 3 series; AL (light duty), BL (heavy duty), or LL (European regular). For new selections we advise the BL series in preference to your AL series since the latter continues to be discontinued as being a acknowledged ASME/ANSI standard series chain. BL series chains are made in accordance with all the ASME/ANSI B29.8 American Leaf Chain Standard. LL series chains are generated in accordance together with the ISO 606 global leaf chain standard.
A chain with an even variety of pitches normally has a 1 male and one particular female finish. It is extra common to get the chain possess an odd quantity of pitches through which case the each ends will 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 noted. Clevis pins, usually with cotters at every single finish, are utilized to connect male chain ends to female clevis blocks. Chains with female ends tend to be (but not generally) connected on the clevis block having a cottered form connecting link. The connecting link is the female finish part in this case.
Leaf Chain Selection
Make use of the following formula to verify the choice of leaf chain:
Minimal Greatest Power > T x DF x SF
T: Calculated Maximum Chain Tension
DF: Duty Element
SF: Services Issue
Note that the greatest allowable chain pace for leaf chains is 100ft per minute.
