Leaf Chains are created for substantial load, slow speed tension linkage applications. Usually they can be specifi ed for reciprocating motion lifting devices such as fork lifts or cranes. These chains are commonly supplied to a specifi c length and are connected to a clevis block at each finish. The clevis may perhaps accommodate male ends (within or in some cases called “articulating” backlinks) or female ends (outdoors or even the hyperlinks about the pin hyperlink) as demanded (see illustration under)
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 to your AL series since the latter continues to be discontinued being a acknowledged ASME/ANSI standard series chain. BL series chains are created in accordance together with the ASME/ANSI B29.8 American Leaf Chain Typical. LL series chains are made in accordance with the ISO 606 worldwide leaf chain normal.
A chain with an even amount of pitches constantly includes a a single male and one particular female end. It can be extra popular to have the chain possess an odd number of pitches during which case the each ends will likely be either male (most common) or female (significantly less com-mon). When ordering lengths with an odd number of pitches male ends are provided unless otherwise noted. Clevis pins, ordinarily with cotters at just about every end, are employed to connect male chain ends to female clevis blocks. Chains with female ends are often (but not often) linked on the clevis block using a cottered type connecting link. The connecting link will be the female end part in this instance.
Leaf Chain Selection
Make use of the following formula to confirm the variety of leaf chain:
Minimum Ultimate Strength > T x DF x SF
T: Calculated Maximum Chain Stress
DF: Duty Component
SF: Support Element
Note that the maximum allowable chain pace for leaf chains is 100ft per minute.
