Leaf Chains are made for higher load, slow speed stress linkage applications. Normally they are really 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 each and every finish. The clevis may perhaps accommodate male ends (within or from time to time known as “articulating” backlinks) or female ends (outside or the backlinks to the pin link) as expected (see illustration under)
Leaf chains are available in three series; AL (light duty), BL (hefty duty), or LL (European conventional). For new selections we advise the BL series in preference to your AL series as the latter continues to be discontinued being a recognized ASME/ANSI conventional series chain. BL series chains are created in accordance with all the ASME/ANSI B29.8 American Leaf Chain Typical. LL series chains are generated in accordance together with the ISO 606 international leaf chain typical.
A chain with an even quantity of pitches normally has a 1 male and one female end. It can be more typical to have the chain possess an odd quantity of pitches through which situation the both ends will likely be both male (most common) or female (much less com-mon). When ordering lengths with an odd variety of pitches male ends are supplied unless otherwise mentioned. Clevis pins, ordinarily 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 normally) connected to your clevis block that has a cottered type connecting website link. The connecting website link could be the female end part in this case.
Leaf Chain Choice
Use the following formula to confirm the selection of leaf chain:
Minimum Greatest Strength > T x DF x SF
T: Calculated Optimum Chain Stress
DF: Duty Component
SF: Support Issue
Note that the optimum allowable chain velocity for leaf chains is 100ft per minute.
