Leaf chain is commonly used in which equipment?

• A. Leaf chain
• B. Roller chain
• C. Sprocket chain
• D. Linked chain

Answer: (A)

Leaf chain is a flat, high-strength chain specifically designed for lifting and hoisting equipment. Its wide, plate-like links distribute load over a larger area and resist the shock and bending that occur when lifting heavy loads. This makes it ideal for chain hoists and similar lifting devices where the chain must handle sudden starts, stops, and heavy loads repeatedly without excessive elongation or wear.

Roller chains are optimized for smooth, efficient power transmission around sprockets in continuous-motion machinery, not for the peak loads and dynamic stresses of lifting. The other terms are generic and don’t capture the lifting-focused design of leaf chain. So, leaf chain is the common choice for hoisting equipment.
