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.

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.
QUICK REFERENCE XIHU (WEST LAKE) DIS.
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 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.
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.
How do automatic car parking chains work, and what are their advantages over manual systems?
Automatic car parking chains are an advanced version of traditional manual parking chains that offer more convenience and efficiency in controlling vehicle access. Here’s how they work and their advantages over manual systems:
1. Automated Operation: Automatic parking chains are integrated with electronic access control systems, such as keycard readers, RFID (Radio Frequency Identification) tags, or remote-controlled mechanisms. When an authorized vehicle approaches the entrance, the system automatically detects the vehicle’s credentials and raises the chain to allow entry.
2. Enhanced Security: With automated access control, there is a reduced risk of human error, which can be a vulnerability in manual systems. Only vehicles with valid credentials can enter, making it harder for unauthorized vehicles to gain access.
3. Time Efficiency: Automated car parking chains operate swiftly, minimizing waiting times for authorized users. This is particularly advantageous in high-traffic areas where manual control could cause congestion during peak hours.
4. Remote Management: Some automatic parking chains can be remotely controlled, allowing operators to manage access from a central location. This can be especially useful for large parking facilities or when physical attendance is not feasible.
5. Integration with Payment Systems: Automated chains can be connected to payment systems, enabling seamless access for users who have paid the required fees or have valid subscriptions.
6. Scalability: Automatic car parking chains can be easily integrated with other smart parking technologies, like ticketing systems or license plate recognition, to create a comprehensive and efficient parking management solution.
7. Reduced Labor Costs: As the system operates automatically, there is no need for manual attendance, leading to potential cost savings in labor.
8. Remote Monitoring: Some advanced automatic systems come with remote monitoring capabilities, allowing operators to track vehicle movement and access patterns in real-time.
Despite these advantages, automatic car parking chains may require higher upfront investment and ongoing maintenance costs compared to traditional manual systems. The choice between the two largely depends on the specific needs and budget constraints of the parking facility or garage.
