LL2866 Series Leaf Chain for Manual Hydraulic Forklifts and Small Tonnage Diesel Forklifts

The LL series plate chains are industrial-grade chains crafted meticulously to endure large pulling forces. Typically used in lifting equipment and forklift lifting mechanisms, they also find application in other scenarios that require linear motion. The robust structure of these chains consists of a series of plate-shaped links, also known as blades, interconnected by pins.

Application of LL Series Leaf Chain

The LL series leaf chain is versatile and has a wide range of applications...

How to choose the pitch of the LL Series Leaf Chain

Choosing the pitch of an LL Series leaf chain is an important decision that can significantly affect the performance and operation of the chain in the application. Pitch refers to the distance between consecutive chain links, usually measured in inches or millimeters. There are some factors to consider when selecting the pitch of LL series leaf chain:Application requirements: The pitch of the chain should be selected according to the specific application requirements. For example, if you require a high-speed chain with low noise and vibration levels, a smaller pitch may be preferred. On the other hand, if you need a chain that can handle heavier loads, a larger pitch may be more appropriate.Load Capacity: The pitch of a chain affects its load capacity. A smaller pitch provides greater strength and support under heavy loads, while a larger pitch may be better suited for lighter loads. Consider the maximum expected load on the chain when making your choice.Chain Length: The length of the chain also affects the pitch selection. Shorter chains typically require smaller pitches to maintain proper tension and alignment, while longer chains may require larger pitches to prevent excessive sag or bending.Space limitations: The space available for chain installation should be considered when selecting pitch. Smaller pitches may require more chain wraps or smaller bend radii, which may not be feasible in limited space. Conversely, a larger pitch allows for more flexible mounting and less chain tangles.Manufacturer's Recommendations: Finally, refer to the manufacturer's recommendations for selecting the appropriate pitch for your LL Series Leaf Chain. Manufacturers can provide guidance based on their product experience and knowledge, taking into account various factors such as material properties, loading conditions and chain dynamics.

The manufacturing process of LL series plate chain

The manufacturing process of LL Series leaf chain typically involves several consecutive steps to create the desired link pattern and ensure its structural integrity. Here is a general overview of the manufacturing process:Raw Material Selection: The first step in the manufacturing process is selecting the right raw material for the chain. These materials can include steel, stainless steel or other alloys, depending on the properties required such as strength, corrosion resistance and cost.Cutting and punching: The raw material is then cut and punched to form individual links. This step involves precision cutting and stamping operations using dies and punches to shape the links to the required specifications.Link assembly: The individual links are then assembled into the desired pattern to form the LL series leaf chain. This step may involve welding, riveting, or other joining methods to securely join the links and maintain their structural integrity.Surface Treatment: After assembly, the chain undergoes a surface treatment process to enhance its corrosion resistance, wear resistance and overall durability. This may involve electroplating, painting, chromating, physical vapor deposition (PVD) or heat treatment, depending on the desired surface properties.Quality Control: Finished chains undergo stringent quality control inspections to ensure they meet specified standards and tolerances. This includes defect inspection, dimensional accuracy and testing to ensure it meets the required performance standards.Packaging and Shipping: Finally, the LL Series Leaf Chain is ready for packaging and shipping. It can be individually boxed, palletized, or shrink-wrapped for protection during shipping and storage. Packaging should be designed to prevent damage and ensure safe delivery to the customer.
