Leaf Chains
Leaf chains, also known as flyer chains, or occasionally fleyer chains, are a special type of chain designed for lifting applications. They are standardized according to ISO 4347 (DIN 8152) for European series or ANSI B29.8 for American series, and are available in both light-duty and heavy-duty versions.
Leaf chains consist of a series of pins onto which plates are alternately assembled along the entire length in various configurations. The ends of the chain can be equipped with attachment plates for mounting or for connection to other components.
We structure our offer of leaf lifting chains by manufacturer. Our key suppliers are:
-
Donghua
Donghua is one of the world’s largest manufacturers of leaf (flyer) chains. These chains are used in most lifting applications – from forklifts, lifting platforms, and container handling systems to offshore platforms and various other industrial operations.
Many leading manufacturers of handling equipment use Donghua chains as standard components.
Donghua leaf chains are available in various designs – such as AL, LLLight Plate + Light Plate, LHLight Plate + Heavy Plate/BL or FFC. Versions with special guides for reduced noise and vibration are also available. On request, the chains can be equipped with accessories, special pins, end fittings, or other modifications tailored to specific load and operating requirements.
-
ČZ
For smaller quantity orders of leaf (flyer) chains, the range from Czech manufacturer ČZ is a suitable choice. The chains are more readily available and generally not subject to minimum production quantities.
ČZ also offers accessories for leaf chains – including end plates, cotter pins, and holders.
Main Types and Design of Leaf Chains
The table below shows the basic classification of flyer chains based on their standardization. In addition to international standards – both European and American – special series defined by individual manufacturers are also available.
Designation | Type | Standard |
---|---|---|
LLLight Plate + Light Plate | Light-duty – European | ISO 4347 (DIN 8152) |
AL | Light-duty – American | ANSI B29.8 |
LHLight Plate + Heavy Plate | Heavy-duty – European | ISO 4347 (DIN 8152) |
BL | Heavy-duty – American | ANSI B29.8 |
Note: Selected LHLight Plate + Heavy Plate (ISO/DIN) and BL (ANSI) chain types are structurally equivalent and interchangeable. Always verify dimensions based on the manufacturer's catalog.

Chains Fields of Use
Leaf (flyer) chains are primarily used in lifting systems and function as tensile load-bearing components.
They are used in lifting devices such as elevators, forklifts, and garage doors, or in any application where steel wire ropes are unsuitable.
Chains Material
Steel.
