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.

How do leaf chains handle reverse motion or anti-reverse requirements?

Leaf chains are designed to handle reverse motion or anti-reverse requirements in lifting applications. They offer a unique design that prevents the chain from backtracking, ensuring the load remains securely in place even during sudden stops or reversals.

The anti-reverse feature in leaf chains is achieved through their construction. Leaf chains consist of link plates connected by pins and retainers, forming a continuous loop. The link plates have a shape that allows them to interlock with one another, creating a self-locking mechanism.

When the chain experiences a reverse motion or tries to move backward, the interlocking link plates engage and resist the motion, effectively preventing the load from descending unintentionally. This anti-reverse capability is crucial for ensuring the safety of lifting operations and protecting both the load being lifted and the equipment.

In addition to their anti-reverse characteristics, leaf chains also offer smooth and quiet operation during forward motion, making them suitable for various lifting applications where controlled and precise movement is essential.

It is important to note that proper maintenance and periodic inspections are necessary to ensure the anti-reverse feature of leaf chains remains effective. Regular lubrication and prompt replacement of worn or damaged components can help maintain the chain’s reliable performance in handling reverse motion requirements.

In summary, leaf chains possess inherent anti-reverse capabilities due to their interlocking link plate design, making them suitable for lifting applications that involve frequent changes in motion direction while maintaining load security and stability.

Can leaf chains be used in overhead storage and retrieval systems?

Yes, leaf chains can be used in overhead storage and retrieval systems, commonly known as overhead cranes or bridge cranes. These cranes are used in various industries, including manufacturing, warehouses, and material handling, to lift and transport heavy loads within the facility.

Leaf chains are well-suited for such applications due to their high tensile strength, durability, and resistance to wear and fatigue. They are capable of handling heavy loads and providing reliable lifting capabilities in continuous operations.

In overhead storage and retrieval systems, leaf chains are typically used in the lifting mechanism, where they connect the hoist unit to the trolley and allow vertical movement of the load. The chains run over the sheaves or sprockets and are driven by a motorized pulley system.

Using leaf chains in overhead crane systems ensures efficient and safe material handling, optimizing the workflow and reducing the risk of accidents. However, it is essential to select the right size and strength of the leaf chain based on the specific requirements of the crane system to ensure smooth and reliable operation.

In summary, leaf chains are a reliable and robust choice for overhead storage and retrieval systems, providing the necessary strength and performance for heavy lifting operations in industrial settings.
