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.

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.
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.

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.

How do I choose the right car parking chain for my parking facility based on traffic volume and vehicle types?
Choosing the right car parking chain for your parking facility involves considering the traffic volume and types of vehicles that will use the facility. Here are the key factors to consider:
1. Traffic Volume:
– For high-traffic areas with a significant number of vehicles entering and exiting frequently, consider a durable and heavy-duty parking chain made from materials like steel or stainless steel. These materials can withstand the wear and tear associated with frequent use.
– For low-traffic areas or temporary parking setups, lighter materials like plastic or PVC chains may be suitable as they are more cost-effective.
2. Vehicle Types:
– For standard passenger cars and small vehicles, most parking chains should be sufficient. However, consider the length of the chain to accommodate wider entry points.
– For larger vehicles, such as trucks or buses, ensure that the parking chain is robust enough to support their weight and size. Opt for heavy-duty chains with thicker links and higher load-bearing capacity.
3. Manual vs. Automatic:
– Manual parking chains operated by attendants may be suitable for smaller parking facilities with moderate traffic. They offer a cost-effective and simple access control solution.
– Automatic parking chains integrated with electronic access control systems are more suitable for larger parking facilities or those with high traffic volume. They provide faster and more efficient access control, minimizing waiting times.
4. Customization:
– Consider whether you require customized parking chains to fit specific dimensions or to align with the overall aesthetic of the parking facility.
5. Environmental Factors:
– For outdoor parking facilities exposed to harsh weather conditions, opt for materials that offer good corrosion resistance, such as stainless steel or aluminum.
6. Budget:
– Determine the budget available for the parking chains, considering both the initial investment and long-term maintenance costs.
7. Compliance:
– Ensure that the chosen parking chains comply with local regulations and accessibility requirements to provide a safe and accessible parking environment.
By carefully evaluating these factors, you can select the most appropriate car parking chain that aligns with your parking facility’s specific needs, ensuring efficient access control and a positive user experience for all vehicle types and traffic volumes.
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.
