| About BL Series Leaf Chain<\/font><\/b><\/span><\/h2>\n

BL (LH) series leaf chains, also referred as forklift chain, made to ASME and ISO standards are constructed of thicker plates and larger pins than<\/font> AL series leaf chain<\/font><\/a> of the same pitch. <\/font><\/font><\/span><\/p>\n

The plates and pin diameter have the same sizes of next larger size in <\/font>roller chains<\/font><\/a>. <\/font><\/font><\/span><\/p>\n

For example, BL6 (LH12) uses plate thickness and pin diameter of ANSI 80 roller chain. <\/font><\/span><\/p>\n

Having high strength and durability, BL series leaf chains are commonly used for lifting equipment, forklift trucks, container lift trucks and material handling applications.<\/font><\/span><\/p>\n

For corrosive environment, <\/font>corrosion resistant coating<\/font><\/a> is available.<\/font><\/span>
<\/font><\/p>\n
