Leaf Chain - Common Facts and Selection

Leaf Chains are manufactured for large load, slow speed stress linkage applications. Usually they are specifi ed for Leaf%20Chainreciprocating motion lifting gadgets such as fork lifts or cranes. These chains are generally provided to a specifi c length and therefore are connected to a clevis block at every finish. The clevis may perhaps accommodate male ends (within or occasionally referred to as “articulating” links) or female ends (outside or even the back links about the pin link) as required (see illustration below)
Leaf chains are available in three series; AL (light duty), BL (hefty duty), or LL (European typical). For new choices we advise the BL series in preference to your AL series since the latter has become discontinued as a recognized ASME/ANSI conventional series chain. BL series chains are made in accordance together with the ASME/ANSI B29.eight American Leaf Chain Regular. LL series chains are created in accordance together with the ISO 606 worldwide leaf chain regular.
A chain with an even number of pitches usually features a one male and one female finish. It truly is more widespread to get the chain possess an odd number of pitches during which case the the two ends are going to be either male (most common) or female (less com-mon). When ordering lengths with an odd amount of pitches male ends are supplied unless otherwise mentioned. Clevis pins, usually with cotters at every single finish, are utilised to connect male chain ends to female clevis blocks. Chains with female ends are sometimes (but not normally) connected on the clevis block that has a cottered style connecting link. The connecting website link would be the female finish component in this instance.
Leaf Chain Assortment
Utilize the following formula to confirm the selection of leaf chain:
Minimum Ultimate Strength > T x DF x SF
T: Calculated Optimum Chain Tension
DF: Duty Factor
SF: Service Issue
Note that the maximum allowable chain speed for leaf chains is 100ft per minute.
