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.
Plate configuration and thickness are the same as ANSI G8 roller chain. Pin diameter is almost the same as ANSI G8 roller chain.
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 mining and excavation equipment?
Yes, leaf chains can be used in mining and excavation equipment for various lifting and pulling applications. Mining and excavation equipment often require heavy-duty components that can withstand harsh and demanding conditions. Leaf chains are well-suited for these environments due to their robust construction and high load-bearing capabilities.
Some common applications of leaf chains in mining and excavation equipment include:
- Bucket Elevators: Leaf chains are used in bucket elevators to lift and transport bulk materials, such as coal, ores, and minerals.
- Draglines: Leaf chains are employed in draglines to control the bucket movements for digging and moving large amounts of earth.
- Excavators: Leaf chains are utilized in the lifting arms and booms of excavators to perform digging and material handling tasks.
- Haul Trucks: Leaf chains are used in haul trucks to support heavy loads during the transportation of mined materials.
- Conveyor Systems: Leaf chains can be incorporated into conveyor systems to move materials efficiently within the mining site.
When using leaf chains in mining and excavation equipment, it is essential to consider factors such as the chain’s load capacity, wear resistance, and resistance to environmental elements like dust, moisture, and chemicals. Regular maintenance and proper lubrication are also crucial to ensure the chains perform reliably and have a long service life in these demanding applications.
Can leaf chains be used in overhead storage and retrieval systems?
Yes, leaf chains can be used in overhead storage and retrieval systems, commonly known as overhead cranes or bridge cranes. These cranes are used in various industries, including manufacturing, warehouses, and material handling, to lift and transport heavy loads within the facility.
Leaf chains are well-suited for such applications due to their high tensile strength, durability, and resistance to wear and fatigue. They are capable of handling heavy loads and providing reliable lifting capabilities in continuous operations.
In overhead storage and retrieval systems, leaf chains are typically used in the lifting mechanism, where they connect the hoist unit to the trolley and allow vertical movement of the load. The chains run over the sheaves or sprockets and are driven by a motorized pulley system.
Using leaf chains in overhead crane systems ensures efficient and safe material handling, optimizing the workflow and reducing the risk of accidents. However, it is essential to select the right size and strength of the leaf chain based on the specific requirements of the crane system to ensure smooth and reliable operation.
In summary, leaf chains are a reliable and robust choice for overhead storage and retrieval systems, providing the necessary strength and performance for heavy lifting operations in industrial settings.
