A leaf chains supplier like Yorkshire’s YB Components will tell you that these chains are a fundamental component in many industrial applications, but especially in lifting and hoisting equipment like forklifts, hoists and cranes. They are popular for these tasks because of their high strength, durability and ability to withstand heavy loads.
Here we take a closer look at leaf chains, how they work and the best practices for keeping them performing well.
How Leaf Chains Work
Leaf chains are constructed from interlinked plates, typically arranged in stacked rows and connected by riveted pins. Not featuring rollers makes the products available through your local leaf chains supplier in Yorkshire particularly well-suited for applications requiring tensile strength rather than rotational movement. This is because when force is applied, these interlinked plates distribute the load evenly, allowing the chain to lift or suspend heavy objects efficiently.
In forklifts, the leaf chain connects the mast to the hydraulic lifting system. Then, as the hydraulic pressure is applied, the mast extends or retracts and the chain transfers this motion to lift or lower the forks. The simplicity of this roller-less design means fewer moving parts that can wear out or fail, making leaf chains reliable under heavy-duty conditions thanks to their tensile strength being superior.
Keeping Leaf Chains Performing Optimally
To ensure leaf chains remain in peak operating condition, regular maintenance and proper handling are essential. To achieve this, leaf chains should be inspected regularly for signs of wear, elongation, corrosion or any other form of damage. Visual inspections can identify issues like cracked plates, rust or pin wear. Measuring the chain’s length can also detect elongation, and when the elongation exceeds 3% of the original length, the chain should be replaced.
Proper lubrication is also critical for reducing friction between the plates and pins, which helps to minimise wear and tear. The right lubricant helps prevent rust and corrosion, especially in environments exposed to moisture or chemicals. They also need to be kept clean, particularly in dirty or dusty environments as leaf chains suppliers in Yorkshire will confirm that the leaf design can trap dirt. The dirt and debris can then accelerate wear by grinding between the plates and pins.
Leaf Chain Alignment and Tension
Ensuring that the chain is properly aligned and tensioned is vital, as misalignment can cause uneven wear and stress. On top of that issue, incorrect tension can also lead to premature failure. Make sure the chain runs straight and true along the sprockets or guides, and the tension should be within the manufacturer’s specified range.
