What's the Difference Between Bl and Al Leaf Chain?

What's the Difference Between Bl and Al Leaf Chain?

2024/9/19
Leaf chains are a type of heavy-duty chain used in lifting, pulling, and balancing applications. They're common in machinery such as forklifts, cranes, and hoists due to their high tensile strength. However, when selecting the right chain for your application, you may encounter two main types: BL (Block Link) and AL (American Link) series. While both serve similar functions, they differ in design, strength, and standards.

Leaf Chain Application

AL chains, with their lighter construction, are often employed in more moderate tasks, like light-duty lifting or smaller-scale industrial machinery.
Due to their higher strength and load-bearing capacity, BL chains are commonly used in heavy-duty machinery such as forklifts, telescopic booms, and material handling equipment. They can also be paired with smaller pulleys, which allows for more compact designs in industrial equipment.
