Leaf Chains are created for substantial load, slow speed tension linkage applications. Typically they can be specifi ed for reciprocating movement lifting gadgets such as fork lifts or cranes. These chains are commonly provided to a specifi c length and are linked to a clevis block at just about every end. The clevis may perhaps accommodate male ends (inside or at times referred to as “articulating” hyperlinks) or female ends (outside or the hyperlinks within the pin website link) as needed (see illustration below)
Leaf chains can be found in three series; AL (light duty), BL (heavy duty), or LL (European regular). For new choices we suggest the BL series in preference to your AL series since the latter is discontinued as being a acknowledged ASME/ANSI normal series chain. BL series chains are created in accordance with all the ASME/ANSI B29.eight American Leaf Chain Normal. LL series chains are made in accordance with the ISO 606 international leaf chain typical.
A chain with an even amount of pitches always includes a one male and a single female end. It really is additional frequent to possess the chain possess an odd quantity of pitches during which situation the both ends might be both male (most common) or female (significantly less com-mon). When ordering lengths with an odd number of pitches male ends are provided unless of course otherwise mentioned. Clevis pins, ordinarily with cotters at each finish, are utilized to connect male chain ends to female clevis blocks. Chains with female ends are sometimes (but not always) linked to your clevis block having a cottered sort connecting link. The connecting website link could be the female finish part in this instance.
Leaf Chain Choice
Make use of the following formula to verify the selection of leaf chain:
Minimal Ultimate Power > T x DF x SF
T: Calculated Highest Chain Stress
DF: Duty Element
SF: Service Issue
Note that the greatest allowable chain velocity for leaf chains is 100ft per minute.
