Leaf Chain – Standard Information and Assortment

Leaf Chains are made for higher load, slow pace stress linkage applications. Normally they’re specifi ed for reciprocating motion lifting products this kind of as fork lifts or cranes. These chains are normally provided to a specifi c length and therefore are connected to a clevis block at just about every end. The clevis could accommodate male ends (inside or at times referred to as “articulating” links) or female ends (outside or the back links around the pin link) as essential (see illustration beneath)
Leaf chains are available in three series; AL (light duty), BL (hefty duty), or LL (European regular). For new choices we endorse the BL series in preference for the AL series as the latter is discontinued like a recognized ASME/ANSI common series chain. BL series chains are developed in accordance using the ASME/ANSI B29.8 American Leaf Chain Regular. LL series chains are created in accordance with all the ISO 606 global leaf chain standard.
A chain with an even variety of pitches always features a one male and 1 female finish. It really is a lot more typical to possess the chain possess an odd variety of pitches in which situation the the two ends will be both male (most common) or female (much less com-mon). When ordering lengths with an odd variety of pitches male ends are provided except if otherwise noted. Clevis pins, normally with cotters at every finish, are used to connect male chain ends to female clevis blocks. Chains with female ends are frequently (but not normally) connected towards the clevis block having a cottered form connecting website link. The connecting website link could be the female finish element in this case.
Leaf Chain Variety
Use the following formula to confirm the choice of leaf chain:
Minimal Greatest Power > T x DF x SF
T: Calculated Highest Chain Tension
DF: Duty Issue
SF: Service Component
Note the highest allowable chain speed for leaf chains is 100ft per minute.
