Leaf Chain – Standard Info and Variety

Leaf Chains are created for substantial load, slow velocity tension linkage applications. Usually they may be specifi ed for reciprocating motion lifting units 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 each end. The clevis could accommodate male ends (within or at times identified as “articulating” links) or female ends (outdoors or even the hyperlinks within the pin website link) as needed (see illustration beneath)
Leaf chains can be found in 3 series; AL (light duty), BL (heavy duty), or LL (European common). For new selections we recommend the BL series in preference for the AL series since the latter has become discontinued as being a acknowledged ASME/ANSI normal series chain. BL series chains are generated in accordance using the ASME/ANSI B29.eight American Leaf Chain Regular. LL series chains are made in accordance using the ISO 606 global leaf chain normal.
A chain with an even amount of pitches constantly includes a one particular male and one particular female end. It really is far more prevalent to get the chain possess an odd amount of pitches by which case the the two ends are going to be both male (most typical) or female (less com-mon). When ordering lengths with an odd number of pitches male ends are supplied unless of course otherwise mentioned. Clevis pins, normally with cotters at each and every finish, are utilized to connect male chain ends to female clevis blocks. Chains with female ends tend to be (but not constantly) linked for the clevis block using a cottered form connecting hyperlink. The connecting hyperlink may be the female finish element in this case.
Leaf Chain Assortment
Make use of the following formula to verify the variety of leaf chain:
Minimal Ultimate Power > T x DF x SF
T: Calculated Greatest Chain Stress
DF: Duty Element
SF: Services Aspect
Note the maximum allowable chain speed for leaf chains is 100ft per minute.
