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.

If you’re not sure exactly what type or size of chain that you need, we have decades of experience working with customers to provide the ideal chain or sprocket to keep you moving. We have a full line of Leaf AL Series Chains as well as Leaf BL Series Chains.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.

What are the common issues and troubleshooting tips for car parking chains, such as jamming or misalignment?
Car parking chains, like any mechanical system, may encounter various issues over time. Here are some common problems and troubleshooting tips to address them:
1. Jamming:
– Troubleshooting: If the chain becomes jammed and doesn’t move smoothly, inspect the chain links and the surrounding area for any obstructions or debris that may be causing the jam. Clean the chain and the chain path to ensure smooth movement.
– Prevention: Regularly clean and lubricate the chain to prevent dirt or debris buildup that could lead to jamming.
2. Misalignment:
– Troubleshooting: If the chain appears misaligned or is not moving along its intended path, check the chain’s tension and alignment. Adjust the tension or realign the chain as necessary to ensure proper movement.
