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.

Can car parking chains be integrated with access control systems, such as key cards or remote controls?
Yes, car parking chains can be integrated with access control systems, allowing for more efficient and convenient vehicle access in parking facilities. Integration with access control systems offers several benefits:
1. Key Cards: Parking chains can be linked to electronic access control systems that use key cards or RFID tags. Authorized users are provided with key cards that they can swipe or tap at the entrance to raise the chain, granting them access to the parking area.
2. Remote Controls: In automated parking chains, remote controls can be used to raise or lower the chains. This is particularly useful for parking attendants or personnel who can remotely manage vehicle access from a central location, reducing the need for physical presence at the entrance.
3. Electronic Passes: Some parking facilities issue electronic passes to authorized users. These passes can be read by sensors at the entrance, automatically raising the chain to allow access without the need for manual operation.
4. License Plate Recognition: Advanced access control systems may use license plate recognition technology to automatically identify and grant access to pre-registered vehicles as they approach the entrance, eliminating the need for physical cards or passes.
5. Time-Based Access: Access control systems can be configured to grant access only during specific times or days. This is particularly useful for parking facilities with restricted access hours or reserved parking spaces for certain users.
6. Enhanced Security: Integration with access control systems improves security by ensuring that only authorized vehicles can enter the parking area, reducing the risk of unauthorized access or parking violations.
7. Efficient Traffic Management: Automated access control systems can process vehicles more quickly, reducing waiting times and traffic congestion at the entrance during peak hours.
By integrating car parking chains with access control systems, parking facilities can enhance security, improve user experience, and efficiently manage vehicle access, making it a popular choice for modern parking facilities.

7. Environmental Certifications: Look for parking chain manufacturers that have obtained environmental certifications or adhere to sustainable production practices.
By choosing eco-friendly car parking chains, parking facility owners and operators can contribute to environmental conservation and sustainability efforts, aligning their operations with green initiatives and reducing their overall ecological impact.
What is a car parking chain, and how is it used in parking facilities and garages?
A car parking chain is a mechanical barrier used in parking facilities and garages to control vehicle access and prevent unauthorized entry. It consists of a sturdy metal chain suspended across the entrance or exit of a parking area.
The chain is connected to two sturdy posts or walls on either side of the entrance. When lowered, the chain obstructs the passage of vehicles, restricting their entry or exit. Conversely, when lifted, it allows authorized vehicles to pass through.
Parking chains are commonly used in places where a more sophisticated access control system like a gate or a barrier arm may not be necessary. They offer a simple and cost-effective solution for managing vehicle flow.
Typically, parking facility attendants or authorized personnel are responsible for controlling the car parking chain. They manually raise and lower the chain using a key or a specialized lock system.
In some cases, modern parking chains may be automated and integrated with access control systems. This can include keycard readers, electronic passes, or even remote-controlled mechanisms, making it more convenient for authorized users to enter and exit the parking area.
Overall, car parking chains serve as a physical deterrent to prevent unauthorized access and ensure better control over vehicle movement in parking facilities and garages.
