Leaf Chain – Standard Info and Choice

Leaf Chains are made for high load, slow pace stress linkage applications. Often they may be specifi ed for reciprocating motion lifting products such as fork lifts or cranes. These chains are commonly provided to a specifi c length and are linked to a clevis block at every end. The clevis may accommodate male ends (within or sometimes known as “articulating” links) or female ends (outdoors or the back links within the pin website link) as expected (see illustration beneath)
Leaf chains can be found in three series; AL (light duty), BL (heavy duty), or LL (European conventional). For new choices we propose the BL series in preference towards the AL series as the latter is discontinued like a recognized ASME/ANSI typical series chain. BL series chains are generated in accordance with the ASME/ANSI B29.eight American Leaf Chain Normal. LL series chains are developed in accordance with all the ISO 606 worldwide leaf chain typical.
A chain with an even number of pitches usually features a one particular male and one female end. It truly is far more widespread to possess the chain possess an odd amount of pitches by which case the the two ends will likely be both male (most typical) 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 each end, are applied to connect male chain ends to female clevis blocks. Chains with female ends are sometimes (but not always) linked to the clevis block by using a cottered type connecting hyperlink. The connecting website link may be the female finish element in this instance.
Leaf Chain Variety
Utilize the following formula to confirm the variety of leaf chain:
Minimal Greatest Strength > T x DF x SF
T: Calculated Optimum Chain Stress
DF: Duty Component
SF: Support Factor
Note the optimum allowable chain speed for leaf chains is 100ft per minute.
