Product Description
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.

Can leaf chains be used in aerial work platforms and scissor lifts?
Yes, leaf chains are commonly used in aerial work platforms and scissor lifts for their reliable lifting capabilities and durability. Aerial work platforms and scissor lifts are equipment designed to elevate workers or materials to various heights, and they require robust and safe lifting mechanisms.
Leaf chains are well-suited for these applications because:
1. High Load Capacity: Leaf chains are capable of handling heavy loads, making them ideal for lifting platforms with varying weight requirements.
2. Strength and Reliability: In aerial work platforms, safety is paramount, and leaf chains are known for their strength and reliability, providing secure lifting operations.
3. Simple Construction: Leaf chains have a simple construction with fewer moving parts, reducing the risk of mechanical failures and simplifying maintenance.
4. Compact Design: The compact design of leaf chains allows them to fit into the limited space available in scissor lift and aerial work platform mechanisms.
5. Cost-Effective: Leaf chains offer a cost-effective solution for lifting applications compared to other more complex lifting systems.
However, it’s essential to ensure that the leaf chains are regularly inspected and properly maintained to ensure safe and efficient operation. Regular lubrication and inspection of the chain and sprockets are crucial to extending the chain’s lifespan and preventing unexpected failures.
In conclusion, leaf chains are a suitable and widely used choice for aerial work platforms and scissor lifts due to their strength, reliability, and cost-effectiveness. When correctly selected and maintained, they provide a safe and efficient lifting solution for various applications in construction, maintenance, and material handling industries.
What are the safety certifications and standards for leaf chains?
Leaf chains used in lifting and rigging applications are subject to various safety certifications and standards to ensure their reliability and performance. Some of the common safety certifications and standards that apply to leaf chains include:
- ISO 4347: This standard specifies the requirements and test methods for leaf chains for general lifting applications. It covers dimensions, strength, and performance characteristics to ensure safe usage.
- ASME B29.8: The American Society of Mechanical Engineers (ASME) standard B29.8 covers leaf chains, including design, dimensions, and minimum performance requirements for leaf chains used in industrial applications.
- EN 818: European Norm (EN) 818 defines the safety requirements for various types of lifting chains, including leaf chains, used in the European Union.
- DIN 8152: Deutsches Institut für Normung (DIN) standard 8152 outlines the design and construction requirements for leaf chains used in lifting and materials handling.
- CE Certification: Leaf chains, like other lifting equipment, may require CE certification to indicate compliance with European safety directives.
