Leaf Chains are created for large load, slow velocity stress linkage applications. Often these are specifi ed for reciprocating movement lifting units this kind of as fork lifts or cranes. These chains are commonly provided to a specifi c length and therefore are connected to a clevis block at every single finish. The clevis could accommodate male ends (inside or from time to time called “articulating” hyperlinks) or female ends (outdoors or the backlinks within the pin hyperlink) as demanded (see illustration under)
Leaf chains can be found in 3 series; AL (light duty), BL (hefty duty), or LL (European typical). For new selections we propose the BL series in preference to the AL series as the latter has been discontinued as being a recognized ASME/ANSI typical series chain. BL series chains are produced in accordance with the ASME/ANSI B29.8 American Leaf Chain Common. LL series chains are made in accordance with the ISO 606 worldwide leaf chain typical.
A chain with an even number of pitches often features a one male and one particular female finish. It is actually extra common to get the chain possess an odd variety of pitches during which case the each ends is going to be both male (most typical) or female (significantly 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 are sometimes (but not normally) connected towards the clevis block that has a cottered style connecting website link. The connecting hyperlink is the female end element in this instance.
Leaf Chain Variety
Utilize the following formula to confirm the collection of leaf chain:
Minimum Greatest Power > T x DF x SF
T: Calculated Greatest Chain Tension
DF: Duty Factor
SF: Services Factor
Note that the optimum allowable chain speed for leaf chains is 100ft per minute.
