What equipment stores and retrieves goods in high-density warehouses?

• A. Conveyor belt
• B. Storage retrieval machine
• C. Automated palletizer
• D. Storage retrieval system

Answer: (B)

In high-density warehouses, the equipment that physically stores and pulls goods from tight, tall racks is the storage retrieval machine. This device, often part of an automated storage and retrieval system, moves along aisles and operates within the racks to place items into storage slots and retrieve them on demand. It’s designed to handle the actual handling task with precision, enabling maximum use of space and fast access.

Other options don’t fit as well. A conveyor belt mainly shifts items from one place to another and doesn’t perform storing into racks. An automated palletizer focuses on stacking goods onto pallets rather than storing them in a shelving system. The storage retrieval system refers to the entire setup, including software and conveyors, not the single device that carries out the storage and retrieval action. So the equipment that stores and retrieves goods itself is the storage retrieval machine.
