AL LL FL LH BL Series Dacromet-Plated Truck Sky Stacker Car Parking Hoisting Machine Conveyor Leaf Chain for Forklift

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.

How do leaf chains perform in high-speed lifting operations?

Leaf chains are generally not recommended for high-speed lifting operations due to their design and construction. While leaf chains excel in heavy-duty and slow-speed applications, they may encounter challenges when used in high-speed lifting scenarios. Here are some factors to consider:

  • Flexibility: Leaf chains consist of interconnected links with little flexibility between them. At high speeds, this lack of flexibility can lead to increased vibration and stress on the chain, potentially causing premature wear and fatigue.
  • Dynamic Loading: High-speed lifting involves rapid changes in load and direction. Leaf chains may not handle dynamic loading as well as other chain types, which could compromise the safety and reliability of the lifting operation.
  • Wear and Heat: The higher the speed, the more friction and heat are generated within the chain. This can accelerate wear and reduce the chain’s lifespan, leading to more frequent maintenance and replacement.
  • Alternate Options: For high-speed lifting applications, roller chains or other types of high-speed lifting chains are more commonly used. Roller chains have better flexibility and are specifically designed to handle dynamic loading and high-speed operations.

It’s essential to carefully consider the specific requirements of the lifting operation and consult with chain manufacturers or lifting equipment experts to choose the most appropriate chain type. While leaf chains are reliable and robust for many lifting tasks, high-speed lifting is one area where alternative chain types may be more suitable for optimal performance and safety.

Can leaf chains be used in tower cranes and construction hoists?

Yes, leaf chains can be used in tower cranes and construction hoists, and they are a popular choice for these applications due to their excellent lifting capabilities and durability.

Tower cranes and construction hoists are essential equipment in the construction industry, used to lift and transport heavy materials and equipment to different heights on construction sites. These applications require robust and reliable lifting solutions to ensure the safety and efficiency of construction operations.

Here’s why leaf chains are suitable for tower cranes and construction hoists:

  • High Strength: Leaf chains are designed to handle high loads and provide reliable lifting performance, making them well-suited for lifting heavy construction materials and equipment.
  • Wear Resistance: The construction environment can be demanding, with exposure to dust, debris, and rough surfaces. Leaf chains are constructed from durable materials and have good wear resistance, ensuring they can withstand harsh conditions and extended use.
  • Minimal Stretch: Leaf chains have minimal elongation, which means they maintain their length and lifting accuracy over time. This characteristic is crucial in construction applications where precise positioning is essential.
  • Compact Design: Tower cranes and construction hoists often operate in confined spaces, and the compact design of leaf chains allows for efficient use of space while providing powerful lifting capabilities.
  • Reliability: Construction projects have tight schedules, and equipment reliability is crucial to meet project deadlines. Leaf chains’ reliable performance and low maintenance requirements contribute to the smooth operation of tower cranes and construction hoists.

Leaf chains are used in various configurations, such as single-strand or multi-strand setups, depending on the specific lifting requirements of the tower crane or construction hoist.

It is essential to select the appropriate size and type of leaf chain based on the load capacity, lifting height, and environmental conditions of the construction site. Regular inspection, lubrication, and maintenance are also necessary to ensure the optimal performance and longevity of leaf chains in tower cranes and construction hoists.
