Leaf Chains are produced for substantial load, slow speed tension linkage applications. Generally they may be specifi ed for reciprocating movement lifting products such as fork lifts or cranes. These chains are generally provided to a specifi c length and are connected to a clevis block at every single end. The clevis may accommodate male ends (within or sometimes called “articulating” backlinks) or female ends (outside or even the hyperlinks within the pin website link) as necessary (see illustration beneath)
Leaf chains can be found in 3 series; AL (light duty), BL (hefty duty), or LL (European regular). For new choices we recommend the BL series in preference to your AL series since the latter has been discontinued as being a acknowledged ASME/ANSI standard series chain. BL series chains are generated in accordance with the ASME/ANSI B29.eight American Leaf Chain Normal. LL series chains are produced in accordance with the ISO 606 global leaf chain standard.
A chain with an even number of pitches often has a a single male and one particular female finish. It is actually extra frequent to possess the chain possess an odd variety of pitches by which situation the each ends are going to be both male (most typical) or female (significantly less com-mon). When ordering lengths with an odd quantity of pitches male ends are provided unless of course otherwise noted. Clevis pins, commonly with cotters at just about every end, are applied to connect male chain ends to female clevis blocks. Chains with female ends are sometimes (but not always) connected on the clevis block which has a cottered sort connecting hyperlink. The connecting website link is the female end part in this case.
Leaf Chain Assortment
Make use of the following formula to confirm the selection of leaf chain:
Minimal Greatest Power > T x DF x SF
T: Calculated Maximum Chain Stress
DF: Duty Aspect
SF: Support Factor
Note that the maximum allowable chain pace for leaf chains is 100ft per minute.
