A chain-driven live roller conveyor is a type of material handling system used to move products from one place to another. It consists of a series of rollers that are powered by a motor and connected by chains to move the product along. The rollers are mounted on bearings and are used to support and guide the product as it moves along the conveyor. The chains provide the necessary force to move the product and are typically made of durable material, such as steel, to withstand heavy loads. Chain-driven live roller conveyors are commonly used in industrial settings for applications such as assembly, packaging, and distribution, and are favored for their versatility and ability to handle heavy loads.
