Horizontal carousels can improve picking accuracy by: Reducing travel time - Horizontal carousels bring the required items directly to the operator, eliminating the need for them to walk or search for the items in a typical storage system. This reduces the chances of picking errors due to confusion or incorrect item identification; Incorporating pick-to-light technology - Many horizontal carousels use pick-to-light technology, where the carousel displays the exact location and quantity of items to be picked. This visual aid helps the operator confirm the right item has been selected and the correct quantity has been picked; Automatic replenishment - Some horizontal carousel systems are equipped with sensors that can signal when inventory levels are low, and automatically restock the carousel with new items. This helps to ensure that the carousel is always stocked with the correct items; Barcoding and scanning - Many horizontal carousels are compatible with barcoding and scanning systems that allow pickers to quickly and accurately identify the right items to be picked. This reduces the risk of human error.
