AL Leaf Chain refers to a specific type of leaf chain used in industrial applications. Here are some key details about the AL leaf chain:

Function: The AL leaf chain is commonly used for heavy-duty lifting, load-bearing, or conveying applications. It is often found in equipment such as forklifts, elevators, construction machinery, and material handling systems.

Leaf Chain Design: The AL leaf chain consists of interlocking plates, known as "leaves," connected by pins. The leaves are wider and thicker than those found in roller chains, providing greater tensile strength and durability.

AL Classification: The "AL" classification indicates that it is an alloy steel leaf chain. Alloy steel leaf chains are made from high-strength alloy steel to withstand heavy loads and resist wear. They undergo heat treatment processes to enhance their strength and toughness.

Maintenance: Regular maintenance, including lubrication and periodic inspection for wear or damage, is crucial to ensure optimal performance and longevity of the AL leaf chain. Following the manufacturer's recommended maintenance guidelines is important to prevent premature failure and maintain proper functionality.

Sizes and Specifications: AL leaf chains are available in various sizes and specifications to accommodate different load capacities and application requirements. These specifications include pitch size, plate thickness, pin diameter, and overall length
