Product Description
Leaf Chain
Leaf chains are known for their durability and high tensile strength. They are primarily used in lift device applications such as forklifts, lift trucks, and lift masts. These hard working chains handle the lifting and balancing of heavy loads with the use of sheaves instead of sprockets for guidance. One of the primary differences with leaf chain compared to roller chain is that it only consists of a series of stacked plates and pins, providing superior lifting strength.
Leaf Chains and Strength
Leaf chains are famous with engineers for their strength in materials handling, such as with forklifts, lift trucks, lift masts, straddle carriers, and other major works of civil engineering. Their long service life, high fatigue strength and maximum wear resistance make them the ideal solution for long-term projects that need to be both reliable and incredibly strong. The compact design of leaf chains allows them to fit well within a variety of systems. The key parts of a leaf chain include:
Link Plates: Close control of the plate dimensions allows for high fatigue strength and long service life.
Pins: The pins pass through the plates and are subject to shearing forces, while the plates articulate on the pins through rotation over the sheave.
Leaf Chain AL Series or Leaf Chain BL Series
The American National Standards Institute (ANSI) determines consensus standards for a wide range of products and processes in the U.S. that are also adopted worldwide. This regulatory body provides the chain industry with specifics around size and strength that govern the manufacture of different types of chains, including leaf chains and roller chains. While these standards do not often change, AL Series was removed from ANSI Standard in 1975. The newer edition of the standard is BL Series, which replaced the AL Series. AL and BL Series are dimensionally different. BL Series has a higher tensile strength than AL Series and is more commonly used today. However, older machinery may still use the AL Series of leaf chain, which is still offered by HangZhou Star Machine Technology Co., Ltd. in a variety of different sizes.

Leaf chains are built of interlaced plates held together by rivet pins. They are built with the same high degree of precision as our roller chains. HKK Leaf chains are used for applications that require strong flexible linkage for transmitting motion or lift. Specially selected steel and unique heat treatment assures high strength and durability. The first number or numbers in leaf chains identifies the chain pitch, the last 2 numbers identify the chain’s lacing. New applications should use BL series leaf chains.

Leaf Chain is the most simple of steel chains, consisting only of link plates and pins. This chain generally has greater tensile strength than roller chains and runs over sheaves rather than sprockets. They are suitable for hanging, balancing or motion transmitting applications. Leaf chains are often used as counterweight chains for machine tools, elevator and oven doors, fork lift truck masts, spinning frames and similar lifting or balancing applications.
Plates are connected by pins and hold the tension loaded on the chain.
AL Type
Plate configuration and thickness are the same as ANSI G8 roller chain. Pin diameter is almost the same as ANSI G8 roller chain.
BL Type
BL Series leaf chains consist of link plates which are thicker and larger in contour than the AL Series link plates of the same pitch. The link plates have the same thickness as the link plates of the next larger pitch size in ANSI G8 roller chains. The pins have the same diameter as those of ANSI G8 roller chains of the next larger pitch.

Can leaf chains be used in stage and theater rigging systems?
Yes, leaf chains can be used in stage and theater rigging systems. Theatrical rigging involves the use of various equipment and mechanisms to move and control stage elements, such as curtains, backdrops, lighting fixtures, and props. Leaf chains are commonly employed in these applications due to their reliable lifting capabilities, high load capacity, and durability.
Stage and theater rigging systems often require smooth and precise movements to create visually captivating performances. Leaf chains are well-suited for these requirements as they offer low vibration and minimal stretching, ensuring smooth and accurate motion during lifting and lowering operations.
The compact design of leaf chains is advantageous in theater settings where space may be limited. Additionally, their ability to handle shock loads and dynamic forces makes them suitable for safely raising and lowering heavy stage elements.
When incorporating leaf chains into stage and theater rigging systems, it is essential to consider factors such as load capacity, speed, and alignment to ensure the safety of performers, crew, and the audience. Regular maintenance and inspection of the leaf chains are also crucial to ensure their continued reliable performance.
In summary, leaf chains are a reliable and efficient choice for stage and theater rigging systems, providing the necessary strength and precision for moving stage elements effectively in a theatrical production.
