LEAF CHAINS
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 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.
LEAF CHAINS STRENGHTH
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.
AL SERIES TYPE AND BL SERIES TYPE
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.
When you need a leaf chain to keep your project in balance, contact the experienced professionals at HangZhou Star Machine Technology Co., Ltd. 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.
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 plateave 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 retrofitted into existing parking facilities to upgrade their security measures?
Yes, car parking chains can be retrofitted into existing parking facilities to upgrade their security measures and access control. Retrofitting parking chains is a practical and cost-effective solution for improving security without the need for major infrastructure changes. Here’s how it can be done:
1. Site Assessment: Conduct a thorough site assessment to identify suitable locations for installing the parking chains. Consider factors such as traffic flow, vehicle types, and entry/exit points.
2. Choose the Right Chains: Select parking chains that are compatible with the existing facility and meet the security requirements. Consider factors like traffic volume, weather resistance, and automation options.
3. Anchor Points: Identify and prepare sturdy anchor points on either side of the entrance or exit where the chains will be installed. Ensure the anchors are securely attached to the ground or wall.
4. Installation: Install the parking chains according to the manufacturer’s instructions, ensuring proper tension and alignment. Consider automatic systems for smoother access control.
5. Integration with Access Control: If using automated parking chains, integrate them with access control systems like key cards, remote controls, or license plate recognition technology.
6. Signage: Install clear signage to inform users about the presence of parking chains and how to operate them.
7. Testing: Test the parking chains’ movement to ensure they raise and lower smoothly without obstructions or jams.
8. Training: Provide training to parking attendants or personnel responsible for operating the chains to ensure proper use and maintenance.

What materials are commonly used to manufacture car parking chains, and how do they affect durability and performance?
Car parking chains are typically manufactured using various materials, and the choice of material can significantly impact the durability and performance of the chains. The most common materials used include:
1. Steel: Steel is the most prevalent material for parking chains due to its high strength and durability. It can withstand heavy loads and resist wear and tear, making it suitable for both indoor and outdoor use. Steel chains are often coated or galvanized to enhance their corrosion resistance and extend their lifespan.
2. Stainless Steel: Stainless steel chains offer excellent corrosion resistance, making them ideal for parking areas in coastal or high-humidity environments. They are less prone to rust and maintain their appearance over time.
3. Plastic or PVC: Plastic or PVC chains are lightweight and cost-effective alternatives to metal chains. While they may not be as strong as steel, they are suitable for low-traffic areas and temporary parking setups. However, they may be less durable and require more frequent replacement compared to metal chains.
4. Brass: Brass chains are sometimes used for their aesthetic appeal, as they have a distinct gold-like appearance. However, they are not as commonly used as steel or stainless steel due to their higher cost and lower strength.
5. Aluminum: Aluminum chains are lightweight and resistant to corrosion, making them suitable for outdoor use. However, they are not as strong as steel or stainless steel, and their use is often limited to less demanding applications.
The choice of material depends on several factors, including the intended usage, environmental conditions, budget constraints, and aesthetic preferences. Steel and stainless steel are the most popular choices for parking chains as they offer a good balance of strength, durability, and resistance to various weather conditions. Plastic or PVC chains are more suitable for temporary setups or situations where cost is a primary concern.
Regular maintenance and proper care, regardless of the material used, will also contribute to the longevity and performance of car parking chains. Periodic inspections, lubrication, and prompt repair of any damage are essential to ensure the chains function effectively and provide reliable access control in parking facilities.
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.
