A locker hub is a high-capacity smart locker installation deployed in high-traffic shared locations to serve as a centralised delivery and collection point for multiple users or organisations. Unlike single-building locker units, locker hubs are typically found in transport hubs, shopping centres, residential complexes, or business parks, and are built to handle large parcel volumes from multiple carriers simultaneously. They operate 24/7 and form a key part of out-of-home delivery networks, enabling last mile operators to consolidate deliveries and reduce individual address stops. Columat designs and deploys locker hub solutions for urban logistics operators, real estate developers, and smart city projects. Related concepts include PUDO points and smart lockers.
