Gravity roller conveyors uses gravity to move materials along a Linear or curved path. They consist of a series of rollers placed at regular intervals along a frame. Objects placed on the rollers move along the conveyor as the rollers rotate freely due to the force of gravity. It is typically less expensive than other types of conveyors, making them a cost-effective solution for many material handling applications. Gravity roller conveyors require minimal maintenance, as they have no moving parts or power source. This reduces the risk of downtime and increases productivity.
