An assembly of interconnected metal links, designed to transmit mechanical power, lift heavy loads, or secure objects. It operates through a series of interlocking oval or specialized links that articulate freely at each joint, allowing flexibility along its length while maintaining high tensile strength. When tension is applied, force distributes continuously through the joined links to pull or hold loads; when tension is released, the joints allow the loop or length to fold, coil, or wrap around sprockets and drums without sacrificing structural integrity.
