Leaf Chains are created for higher load, slow pace stress linkage applications. Normally these are specifi ed for reciprocating motion lifting devices such as fork lifts or cranes. These chains are usually supplied to a specifi c length and therefore are connected to a clevis block at every finish. The clevis may accommodate male ends (inside or at times known as “articulating” hyperlinks) or female ends (outside or even the links to the pin website link) as necessary (see illustration below)
Leaf chains can be found in three series; AL (light duty), BL (heavy duty), or LL (European normal). For new choices we suggest the BL series in preference towards the AL series as the latter has been discontinued like a acknowledged ASME/ANSI conventional series chain. BL series chains are made in accordance together with the ASME/ANSI B29.8 American Leaf Chain Conventional. LL series chains are created in accordance with all the ISO 606 international leaf chain regular.
A chain with an even number of pitches often features a one particular male and a single female finish. It is actually additional common to possess the chain possess an odd quantity of pitches through which situation the the two ends will likely be either male (most typical) or female (significantly less com-mon). When ordering lengths with an odd variety of pitches male ends are provided unless otherwise noted. 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 frequently (but not constantly) connected to the clevis block having a cottered style connecting hyperlink. The connecting link may be the female finish element in this case.
Leaf Chain Assortment
Make use of the following formula to verify the collection of leaf chain:
Minimal Ultimate Power > T x DF x SF
T: Calculated Highest Chain Tension
DF: Duty Issue
SF: Support Issue
Note the optimum allowable chain speed for leaf chains is 100ft per minute.
